WPC120 - High Temp Heat Shrink

 High Temp Heat Shrink for Pipelines

Covalence WPC120

     In the world of pipeline coatings, many different factors are important criteria for selecting the proper external corrosion prevention coating for your project. These can range a great deal, depending on the priorities for the engineers associated with any given pipeline project.  One thing never changes though:  the pipe coating must be compatible with the operating temperature of the pipeline.

     Elevated temperatures on pipelines can present quite a challenge to pipeline coatings.  Elevated temperatures can make some products become brittle.  High temperatures can make adhesives and sealant soften, leading to reduced peel, sheer and penetration resistance.  Temps can also lead to cracking and worse cathodic disbondment results.  "What is the operating temp of the line once it is in service" is almost always my starting point when working with someone to be sure our products are properly specified.  

     Covalence WPC120 is a heat shrink sleeve rated for use on pipelines operating at up to 251F.  WPC120 can also be used on pipelines operating at something less than 251; that is just the maximum.  Available in sleeve widths of 11", 17", 24" or 34" (can also offer custom widths as needed) it is the perfect selection for pipelines operating at high temps.

     Though WPC120 is not compatible with factory coated PP; with a few modifications, it becomes a sleeve system called PPS120 that can.  Give me a call so we can discuss your next project!  Steve - 936/321-3333

    Covalence WPC120 is our highest rated PE shrink sleeve in terms of operating temperature of the pipeline it is designed to protect the field joints on your pipelines that will operate at up to 251F (120C).  That is pretty much the maximum temperature that a PE can be used.  

     Designed to work with FBE, PE and other common pipeline coatings; WPC120 CAN be used with PP as well, but it requires some additional components to create a coating system rather than a simple single shrink sleeve coating.  

     Available in widths of 11", 17", 24", 34" or something custom, whatever you need we can make it happen (but 34" is the max). 

     Currently I have thousands of feet of WPC120 on hand, ready for your project (that you likely forgot to order the shrink sleeves for!).  Give me a call to discuss how I can help you get out of a bind....even if you just need a few hundred sleeves quickly to get your project started.

WPC120 Shrink Sleeve

High Temp Shrink Sleeve WPC120

Rated for use at 120C (251F) WPC120 is our highest rated shrink sleeve

     WPC120 heat shrinkable wrap around sleeves are designed for corrosion protection of girthwelds on buried pipelines operating at temperatures up to 120C.  WPC120 sleeve have a thick radiation crosslinked polyolefin backing coated with a high shear strength thermoplastic hotmelt adhesive.  during the installation the adhesive melts and flows, filling surface irregularities, bonding to metal and adjacent coated surfaces.
   
     At operating temperatures the adhesive and backing form a solid, tough, well bonded coating.  The flexible closure is coated with a high shear strength adhesive and is normally supplied separately with the sleeve; however, it is available pre attached to the sleeve in the unisleeve construction.

     To install, wrap the sleeve around a clean, preheated pipe (230C minimum).  A flexible closure forms the sleeve into a tube.  The sleeve is then torch shrunk and installed with simple tools.  No powder, primer or sophisticated equipment is required.  However, an induction heater can be used to reduce preheat time.

     WPC120 sleeves resist abrasion, impact and penetration, yet remain flexible even at very low temperatures.  No rock shield is required.

     WPC120 sleeves resist temperature cycling, soil stresses and hydrostatic pressure.  They demonstrate high resistance to ultraviolet light, fungus, cathodic disbondment and chemical attack by common fluids and solvents.  WPC120 sleeves are compatible with FBE, PE and most other high performance pipe coatings (but not PP unless a mastic material is used as the bonding agent).  The product has a long shelf life and is unaffected by typical storage conditions.
