From Alaska to Memphis: The Evolution of Heat Shrink Technology

 

“Long distance information, get me Memphis, Tennessee!”

That’s where this stop takes us—June of 1976. The pipeline industry was in the middle of a quiet but important transition, and once again, innovation was being driven by necessity.

Not long before this, Raychem had made a name for itself by developing coatings used on the Trans-Alaska Pipeline System. One of those key products, Arcticlad, was engineered for extreme conditions—applied with specialized equipment on the unforgiving slopes of Alaska.

But as with most innovations, the next challenge wasn’t invention—it was adaptation.

By the time we arrive in Memphis, Raychem is working to modify that same Arcticlad technology for a much more practical application: coating pipe bends in the field—without the need for large, specialized equipment.

This was a big deal.

Bends have always been tricky. Unlike straight pipe, they introduce geometry that doesn’t cooperate easily with rigid or pre-formed coatings. The goal here was to create something flexible, field-friendly, and reliable—without sacrificing performance.

What we see in these early applications is a product that works… but still has some growing up to do.

Today, that evolution has led us to Flexclad Heat Shrinkable Tape—a far more refined and contractor-friendly solution.

Available in:

• 2", 3", and 4" widths
• 50-foot rolls

Flexclad is designed specifically for applications like these—tight geometries, field installs, and situations where simplicity matters. Even better, it’s readily available and kept in stock at our production facility in Conroe, Texas, just outside The Woodlands.

The photos from that 1976 Memphis job tell a familiar story—one that anyone who has ever worked with a “new” product can appreciate.

It’s a bit clunky.

You’ve got:

Hand application

One person dedicated to running a torch just to keep the pipe preheated

Constant adjustments to get the material to cooperate

And the result?

Functional—but not exactly pretty.

Wrinkles show up throughout the installation. At first glance, you might assume poor adhesion or trapped air. But in reality, those wrinkles are something different: pockets of adhesive that cooled too quickly, before the heat-shrink backing had a chance to fully conform and smooth out the surface.

In other words—it wasn’t a failure. It was a process still being refined.

What makes this moment in Memphis interesting isn’t just the product—it’s the process.

This is what innovation actually looks like in the field:

• Trial and error
• Imperfect installations
• Learning how materials behave outside of controlled environments

Those early “good enough” results laid the groundwork for the solutions we take for granted today.

Modern products like Flexclad eliminate many of those early challenges:

• Easier handling
• More forgiving installation
• Consistent performance across a range of conditions

The jump from Arcticlad on the Alaskan slopes to Flexclad in today’s field applications is a great example of how the industry evolves—not in giant leaps, but in steady, practical improvements.

Memphis, 1976 wasn’t about perfection. It was about progress.

And sometimes, a few wrinkles are just part of getting there.

A Look Back at Innovation (and Cigarettes) on the Pipeline Right-of-Way

 

Let’s start with the real question—because you know it crossed your mind too: back in the 1970s, how many packs of cigarettes did a pipeline crew go through in a single day? A carton? More? Honestly… I’d believe it.

Different time, different jobsite culture. And while a lot has changed since then, one thing hasn’t: the constant push to solve problems in the field.

We’re still in Bakersfield, California, in the early days of wrap-around shrink sleeve technology. At this point, the industry was transitioning from tubular sleeves—an important innovation, but one that came with limitations.

This particular project introduces a new challenge: an insulated pipeline.

The original tubular sleeves developed by Raychem were designed to slide over the pipe before welding. That works well—until insulation enters the picture.

With an insulated line, a tubular sleeve would have needed to:

• Be large enough to fit over the insulation during installation
• Still be capable of shrinking tightly down onto the steel pipe

That’s a big ask.

This is where the wrap-around shrink sleeve starts to shine.

Instead of sliding over the pipe, it wraps around the joint after welding—making it far more adaptable, especially in cases like insulated lines or field repairs.

It’s another example of Raychem doing what they did best:

• Thinking ahead
• Solving problems before they became widespread
• Constantly innovating for new applications 

It’s a mindset you still see today from companies like Henkel—always working multiple angles and anticipating what the market will need next.

Now, if you take a closer look at this particular installation… it’s not winning any awards.

There are visible wrinkles in the closure strip—something that would raise eyebrows today. But context matters:

• The technology was brand new
• Installers were still learning the process
• Best practices were being developed in real time

So if you happen to be the installer from 1976 reading this—no disrespect. You were laying the groundwork the rest of the industry would build on.

CCS Weave: The High-Shrink Material That’s Changing the Game

 

When it comes to high-performance sealing solutions, Covalence has engineered something truly remarkable: CCS Weave. This innovative material is used to create Casing Seals, Flange Seals, and other applications where a high-shrink product is essential. But what makes CCS Weave stand out in a crowded market? Let’s dive in.

1. Unmatched Shrink Ratio
CCS Weave boasts an impressive 66% shrink ratio. To put that into perspective: a 24-inch casing pipe could see the Caseal shrink all the way down to just 8.5 inches if allowed. This dramatic shrink capability ensures a tight, secure fit, even on irregular surfaces.

2. Durable, Multi-Layer Construction
At the heart of CCS Weave is a fiber-reinforced sheet laminated between two layers of polyethylene. This construction delivers exceptional performance in key areas:

• Penetration resistance – tough enough to withstand challenging environments
• Abrasion resistance – maintains integrity over time
• Elongation – flexible enough to handle complex applications

3. Hyper-Aggressive Mastic Sealant
A seal is only as good as the bond it creates. CCS Weave utilizes a hyper-aggressive mastic sealant that adheres well to a variety of substrates—even when surface preparation isn’t perfect. This ensures reliable sealing performance across diverse field conditions.

High-shrink materials can introduce a unique problem: how to keep the material intact during the shrinking process. Covalence tackled this challenge by borrowing a brilliant technique from Raychem, developed decades ago. Since 1995, we’ve been sewing a nylon zipper into the sleeve using Kevlar thread.

When the ends of the sleeve are zipped together, even the extreme 66% shrink ratio isn’t enough to break the threads. This simple yet ingenious solution allows CCS Weave to deliver maximum shrink performance without compromising structural integrity.

CCS Weave isn’t just another sealing material—it’s a high-performance solution designed to meet the demands of today’s toughest applications. With its impressive shrink ratio, multi-layer durability, and clever engineering, it’s a product that engineers and field teams alike can rely on.

It’s more than cool—it’s next-level material innovation.

Stopaq: The Common Sense Tank Chime Repair Solution

If you’ve followed some of my previous posts on Stopaq visco-elastic coating systems, you’ve likely seen how effective they can be when it comes to repairing and recoating tank chimes. Today, I want to walk through the application process—and highlight a few key advantages that really set this system apart in the field.

One of the first things that stands out is the minimal surface preparation required. Unlike traditional coating systems that often demand abrasive blasting and extensive prep work, this process eliminates the need for sandblasting altogether. That alone can significantly reduce both project complexity and cost.

Another major benefit is the simplicity of the application. There’s no need for specialized spray equipment or complex tooling. The system is designed to be straightforward and user-friendly, allowing crews to get the job done efficiently without a steep learning curve.

And perhaps most importantly, the time savings are substantial. Because of the streamlined process, you can complete projects with fewer crew members and in far fewer hours compared to conventional methods. In today’s environment—where labor availability and project timelines are constant challenges—that’s a game changer.

If you’re looking for a faster, simpler, and more efficient way to handle tank chime repairs and recoating, this is definitely a system worth considering.

Feel free to reach out if you’d like more information or want to discuss how it could fit into your next project.

• Tie-ins and fittings

Why? Because it offers:

• Excellent adhesion to FBE, liquid epoxies, and even coal tar epoxy (CTE)

• Strong mechanical properties

• The flexibility to be hand applied depending on the jobsite needs

One of the biggest advantages of Powercrete J is how adaptable it is in real-world conditions.

• Steel: SSPC-SP10 (Sa 2½) abrasive blast recommended

• FBE: SSPC-SP7 (Sa 1) sweep blast to remove gloss

• Handles situations where full blasting isn’t feasible

As long as the substrate temperature is at least 5°F above dew point, you're good to go.

• Can be applied up to 20 mils (500 microns) per layer

• Multi-coat builds up to 60 mils (1500 microns) depending on requirements

Powercrete J is designed to be user-friendly and efficient.

From the Product Data Sheet, a few highlights worth calling out:

• ~40.1 ft² per gallon at 40 mils

Another area where Powercrete J really delivers is availability and logistics.

• Offered in 2 lb, 4 lb, 10 lb, or custom kits

• Orders typically ship within 1 day (often same day)

• Common order sizes range from 8 kits to 20–30 kits

Bottom line: no order is too small, and you won’t be waiting around when the job is ready to move.

If you’re working in HDD, bores, or any application where coatings take a beating, Powercrete J has proven itself time and time again. But its versatility also makes it a strong candidate for standard field joints and rehabilitation work.

It’s that combination of performance, flexibility, and availability that keeps contractors coming back to it.

If you haven’t looked at Powercrete J recently—or only think of it as an HDD coating—it might be time to take another look.

Understanding Covalence’s WPCT Thermal Indicator: A Built-In Inspection Tool

For those who may not be familiar, WPCT from Covalence is a wrap-around heat-shrinkable sleeve designed for pipeline corrosion protection. One of the most interesting features of this product is its built-in thermal indicator, which essentially acts as a built-in inspection tool for installers and inspectors in the field.

When the sleeve is first supplied, the backing material displays a distinct cross-hatch pattern. This pattern is intentional and serves a very practical purpose.

During installation:

• Before heating: The sleeve shows the cross-hatch pattern across the backing.

• During proper heating: As the installer applies heat, the backing begins to shrink.

• After reaching the correct temperature: The cross-hatch pattern disappears and becomes smooth.

That smooth appearance indicates two important things have happened:

1. The sleeve has shrunk as much as the pipe substrate allows.

2. The mastic sealant has reached the correct temperature to properly flow and fill, ensuring a complete seal around the pipe.

In other words, the visual change from cross-hatched to smooth confirms that the sleeve has reached the proper installation temperature.

For pipeline inspectors and coating crews, this built-in indicator provides a simple but powerful benefit: instant visual confirmation of proper installation.
This type of backing technology isn’t limited to WPCT alone. Variations of the same thermal indicator backing are used across several products in the Covalence lineup, including:
Despite many innovations in pipeline coating systems over the years, Covalence heat shrink sleeves remain widely used both in the United States and around the world. Their durability, ease of inspection, and reliable sealing performance continue to make them a trusted choice for field joint coatings.

Rather than relying solely on temperature guesses or installer experience, the sleeve itself provides feedback. If the cross-hatch pattern remains visible, more heat is required. When the backing becomes smooth, the sleeve has reached the correct thermal state.

This feature helps improve:

• Installation consistency

• Inspection confidence

• Long-term coating performance

This same backing is used with the following products (and some that I haven't listed)

• WPCT

• WPC65M

• WPC100M

• HTLP60

• HTLP80

• WPC120

• TPS

Each of these products utilizes similar heat-shrink technology designed to provide reliable sealing and corrosion protection for pipeline field joints.

Today, Covalence operates as part of Seal For Life / Henkel, and the technology traces its origins back to the pioneering pipeline innovations of Raychem Corporation.

Even decades after their introduction, these heat-shrink systems continue to prove that simple visual engineering can make a big difference in the field.

 

ScarGuard: The New ARO

In recent years, one of the fastest-growing products in the pipeline industry has been ScarGuard from Seal For Life Industries.

If you want the informal description?

Think of it as a field-applied ARO… on steroids, testosterone, and nine cups of coffee.

If you prefer the technical version:

A fiber-reinforced composite mechanical protection system designed for HDD and other demanding applications.

 ScarGuard is a moisture-curable, fiber-reinforced wrap engineered to deliver serious mechanical protection. Once cured, it forms a tough composite shell around the pipeline — dramatically increasing resistance to:

• Abrasion

• Impact

• Gouging

• Shear forces during pullback

• Damage from sharp or rocky backfill

And in today’s environment, that matters more than ever.

As more pipelines are installed via horizontal directional drilling (HDD) and routed through rocky or unforgiving soil conditions, owners are becoming less comfortable relying solely on traditional ARO systems.

We’re seeing a growing trend:

• End users adding ScarGuard over field joints

• Owners specifying it as added protection over factory-applied coatings

• Projects in rocky terrain incorporating it as a risk-reduction strategy

Because when you’re pulling thousands of feet of pipe through abrasive conditions, the cost of extra protection is small compared to the cost of failure.

ScarGuard doesn’t replace your corrosion coating system — it enhances it.

It acts as a mechanical armor layer, giving your pipeline a fighting chance in conditions where standard protection may be pushed to its limits.

In challenging soils, HDD crossings, or projects where downtime simply isn’t acceptable, that added durability can make all the difference.

From the Jungle to the Jobsite: Raychem LTPS in Iquitos, Peru (1975)

 Get your passports ready — we’re heading to Iquitos, Peru, July 1975.

The project? A 24” crude oil pipeline.
The setting? Deep in the Amazon.
The timing? Right at the beginning of a coating revolution.

When this line was being built, Raychem’s pipeline division was barely two or three years old. The division really began gaining traction around 1972–1973, meaning this Peru project happened while the market was still very much in its infancy.

At the time, traditional field joint protection methods like:

• Cold-applied tape

• “Granny ragging”

• Other hand-applied systems

were the norm.

And then came heat-shrink technology.

Raychem’s LTPS (Large Tubular Pipe Sleeves) were quickly becoming a serious disruptor. For many contractors, this was their first exposure to a system that combined:

• Factory-engineered consistency

• Strong technical performance

• Faster, more predictable application

• Improved long-term corrosion resistance

Compared to traditional methods, tubular shrink sleeves offered something different: engineered performance rather than improvised craftsmanship in the ditch.

(And yes — if you’re still a believer in granny ragging as the pinnacle of technical achievement, we can respectfully agree to disagree.)

It’s important to remember where we are in the timeline.

In 1975, Raychem had not yet introduced the wraparound shrink sleeve. That innovation was still about a year away. At this stage, LTPS products were slipped over the pipe before welding — a method that required planning but delivered strong, uniform protection once installed and shrunk.

The wraparound sleeve would eventually change field joint coating logistics forever. But in Iquitos, tubular sleeves were already proving that heat-shrink technology could compete — and win — against legacy systems.

Projects like this 24” crude oil line in Peru weren’t just installations — they were proving grounds.

They demonstrated that:

• Heat-shrink sleeves could perform in challenging environments.

• Application speed could improve without sacrificing technical performance.

• Innovation in field joint coatings was not only possible — it was necessary.

In 1975, the pipeline coating market was just beginning to evolve. What seemed disruptive then is now standard practice.

And it all happened one joint at a time — even in the middle of the Amazon.

Stopaq Offshore Success: Re-Sealing the Angel Platform Roof in Australia

 

In 2012, Stopaq had the opportunity to take on a challenging offshore project quite literally “down under” — re-sealing the roof of the Angel offshore platform off the coast of Australia.

Offshore environments are never forgiving. Constant UV exposure, salt-laden air, temperature swings, and moisture intrusion combine to accelerate coating breakdown. In this case, the existing coating system had degraded much faster than anticipated due to the particularly harsh offshore conditions.

The client needed more than just a replacement coating. They needed a system that could truly withstand the environment long term.

For this project, several critical boxes had to be checked:

• Flexibility to accommodate movement and structural shifts

• High resistance to chlorides to prevent blistering commonly seen with traditional paint systems

• Tolerance to significant temperature fluctuations

• Extended UV resistance under constant sun exposure

Traditional coatings often struggle in one or more of these areas — especially when it comes to chloride resistance and long-term UV stability in offshore environments.

The Stopaq Solution: A Two-Component System

The approved system utilized:

• Stopaq Wrappingband EZ

• Stopaq Topcoat

Stopaq Wrappingband EZ

Wrappingband EZ delivered a simple, highly effective sealing solution with several key advantages:

• Minimal surface preparation required

• Wide application window for installers

• Immediate watertight sealing

• Maintains flexibility and structural integrity for foot traffic and movement

In offshore applications, ease of application is not just a convenience — it reduces labor exposure time and improves consistency. Wrappingband EZ created a durable, flexible barrier that addressed moisture intrusion at its source.

 To ensure long-term UV performance, Stopaq Topcoat was applied directly over the Wrappingband EZ.

This added UV-resistant protective layer ensured the system could withstand prolonged sun exposure without degradation — a critical factor for roof applications in offshore Australia.

---

The Result: All Boxes Checked

Once again, a Stopaq system provided a tailored solution that met every requirement:

• Flexibility

• Chloride resistance

• Temperature durability

• UV protection

Offshore projects demand systems that perform under relentless environmental stress. In this case, Stopaq delivered a proven, practical solution designed for exactly those conditions.

When the environment is at its harshest, having the right system in place makes all the difference.

Powercrete J: The Premier Two-Part Epoxy for Field Joint Protection

When it comes to protecting pipeline weld joints, not all coatings are created equal. In demanding applications like directional drills and road bores, the stakes are even higher. Abrasion resistance, adhesion, and long-term corrosion protection aren’t optional — they’re essential.

That’s where Powercrete J stands apart.  It was built for Directional Drills and Road Bores

In HDD (horizontal directional drilling) and road bore installations, pipelines are subjected to:

• Extreme abrasion during pullback

• High soil stress and friction

• Challenging environmental conditions

Powercrete J has earned its reputation as a premier two-part epoxy field joint coating specifically because it performs under these exact conditions. Its abrasion resistance and bond strength make it a go-to solution when the weld joint cannot be the weak link.

When you’re pulling thousands of feet through a bore, the last thing you want is coating failure at the weld.

Here’s something many people don’t realize:  Powercrete J isn’t just for HDD and road bores.

It’s also an excellent solution for standard field joints. Even in conventional installations, weld areas deserve the same level of protection as the factory-applied coating. Using a high-performance epoxy ensures continuity of corrosion protection across the entire pipeline.

If your pipe has been factory coated with Powercrete-DD, the recommendation is simple:

Pair it with Powercrete J for the field joints.

Powercrete-DD is widely recognized as one of the best abrasion resistant overcoats (ARO) on the market. And if your pipeline deserves that level of factory protection, it only makes sense to extend that same standard to the weld joints.

Powercrete J is available as a standard in:

• 2-pound kits

• 4-pound kits

Custom kit sizes are also available upon request, giving contractors flexibility depending on pipe diameter and project scope.

Want to See It for Yourself?

If you’re in the United States and would like to get your hands on a sample, let’s talk. There’s no substitute for seeing how a product handles in real-world conditions.

When it comes to protecting weld joints — whether in a challenging directional drill or a standard pipeline installation — Powercrete J delivers performance you can trust.

Because your pipeline deserves more than “good enough.”

STOPAQ Offshore Success in the Arabian Gulf: Speed Without Sacrificing Performance

 

When it comes to offshore pipeline construction, time truly is money. Every hour on a barge carries significant cost, and any process that slows production can quickly turn into a major financial setback.

That was exactly the concern for a major project in the Arabian Gulf, where a client was searching for a better way to handle offshore field joint coatings on pipe sizes ranging from 4” to 18”. The project spanned from 2012 to 2014 — and the mission was clear:

Field joint coating could not be the bottleneck.

The Challenge: Fast, Reliable, Offshore-Ready

The client’s requirements were straightforward — but demanding:

• A system that was quick and easy to apply

• Proven, robust, and reliable performance offshore

• Ready to hit the rollers and face the sea in a very short timeframe

• Minimal HSE concerns

• No unnecessary equipment or complicated prep procedures

If you’ve spent any time offshore, you know how difficult it can be to balance speed with long-term corrosion protection. Many coating systems look good on paper but slow down production with cure times, blasting requirements, or complex heating procedures.

This client wasn’t willing to take that risk again.

The STOPAQ Solution

The winning system centered around STOPAQ, combining:

• Wrappingband CZHT

• Outerwrap

• High Impact Shield HT

• Rockshield

Together, these components delivered exactly what the project demanded.

One of the biggest advantages of the STOPAQ Wrappingband CZHT system is its surface prep requirements.

Instead of full abrasive blasting, surface preparation could be achieved with simple power tools. Offshore, this is a game changer. Less equipment, less logistical complexity, and less downtime.

Speed was critical.

With STOPAQ Wrappingband, there is no cure time required before applying the Outerwrap and High Impact Shield HT. Application can proceed immediately.

That dramatically reduced the cycle time per joint compared to other technologies under consideration — especially those requiring primer cure times or complex heating sequences.

On a barge, shaving minutes off each joint adds up quickly.

The system required:

• Less heating equipment

• No hazardous primers

That means fewer HSE risks, simplified compliance, and a safer working environment for crews — all while maintaining coating integrity.

In offshore environments, fewer variables often equal fewer problems.

The coating system was ready to see rollers and seawater within a very short time frame. There was no waiting around for cure development or strength build-up.

For offshore contractors, that kind of reliability isn’t a luxury — it’s essential.

Checking Every Box

The client essentially submitted a checklist. The STOPAQ system checked every one:

Quick and easy to apply

Proven offshore performance

Reduced cycle time

Minimal surface prep requirements

Lower equipment demands

Improved HSE profile

Ready for immediate handling

From 2012 through 2014, this project demonstrated that STOPAQ isn’t just a corrosion solution — it’s a production solution.

Revisiting a Milestone in Raychem History: The Great Trans-Alaskan Pipeline Challenge (August 1975)

 

In August of 1975, Raychem found itself at the center of a historic moment in the oil and gas industry. The Trans-Alaskan Pipeline, a massive undertaking that would transport oil from the Alaskan wilderness to the rest of the world, was facing significant delays. One of the primary challenges? A substantial amount of pipe coated with Fusion Bond Epoxy (FBE) had been left exposed to the harsh UV rays of the Alaskan sun for far too long. As a result, the FBE began to degrade, jeopardizing the integrity of the entire pipeline.

Enter Raychem: a company known for its innovative solutions, but this time, the task ahead was nothing short of extraordinary. Raychem was given a daunting proposition: find a way to re-coat thousands of feet of exposed pipe without needing to ship it anywhere. The clock was ticking, and the stakes were high.

Raychem’s team immediately sprang into action. They understood that solving this issue wasn’t just about fixing a problem; it was about developing a solution that could be deployed quickly and effectively in some of the most remote and challenging conditions on Earth.

The result? Arcticlad. A revolutionary product—a spiral-wrapped, heat-shrinkable tape—was born. This tape could coat long lengths of pipe with precision, effectively protecting the pipeline and preventing further damage from UV exposure. But there was one more hurdle to overcome: the installation. Raychem didn’t just create a new product; they also engineered the machinery needed to apply the Arcticlad tape in the field.

This was a true engineering marvel. The teams worked tirelessly, and within an incredibly short amount of time, they had a solution that was both effective and scalable.

The success of Arcticlad wasn’t just a technical win. It was a business triumph that would have lasting implications for Raychem’s future. The ability to offer a cost-effective, field-deployable solution allowed the company to generate significant revenue while cementing its reputation as a leader in pipeline coatings. This success didn’t just solve a problem—it set the stage for Raychem’s pipeline division to thrive in the years to come, establishing a legacy that would last for decades.

Thanks to the ingenuity, quick thinking, and relentless dedication of the Raychem team, the Trans-Alaskan Pipeline project became more than just a milestone—it was a defining moment that helped Raychem’s pipeline division flourish and remain a leader in the industry for many years.

This remarkable chapter in Raychem’s history shows how, with the right combination of innovation, determination, and teamwork, a challenge can be transformed into an opportunity that reshapes the future.
