This may surprise some folks in the pipeline world, but simple tubular shrink sleeves are still very much in use—especially on smaller diameter pipe. In fact, for many applications, they remain a practical, reliable, and cost-effective solution.
One standout example is Covalence TPS (Tubular Pipe Sleeve), formerly a Raychem product, which continues to see strong demand in the field.
A Proven Solution for Small Diameter Pipe
TPS is available for pipe sizes ranging from 2” through 8”, making it a go-to option for smaller diameter pipelines where simplicity and speed matter. Despite the evolution of field joint coatings over the years, TPS has held its ground—and for good reason.
Straightforward Installation, Strong Performance
Installation is refreshingly simple:
-
The TPS sleeve is slipped onto the pipe prior to welding
-
Once the weld is complete, the sleeve is slid back into position
-
The release liner is removed
-
The sleeve is then shrunk in place using a propane torch
No blasting required—wire-brushed pipe surfaces are sufficient, thanks to the highly aggressive mastic sealant that delivers a reliable seal and long-term protection.
If you’ve ever wondered whether TPS is still actively used, consider this:
the pallets stacked behind this sleeve are all TPS. We keep large volumes in stock, with each sleeve providing 18 inches of pipe coverage prior to shrinking. That kind of inventory doesn’t exist unless the product is still solving real-world problems.
TPS may not be the right answer for every project—but when conditions, pipe size, and installation requirements line up, it can be an excellent fit.
If you think Covalence TPS tubular shrink sleeves might work for your application, we’d love to talk it through with you. Sometimes, the simplest solutions are still the best ones.
