TPS and WPCT Shrink Sleeve
(Covalence / Raychem)

| A roll of WPCT material |
One of the very first, original shrink sleeves was an early form of TPS. It was a tubular sleeve, bonded into the form of a tube in the plant. It was originally offered for pipe sizes 2" through 12". The sleeves did revolutionize the market taking business away from cold applied tapes, from coal tar joint applications and from granny ragging the field joints. Suddenly with TPS on the market, field joint applications were faster, more consistent, simpler and technically superior.
Having seen the success of the TPS product, Raychem created the WPC sleeve (wraparound pipe coating). After a few iterations, WPC eventually became WPCT (when the Thermal indicator was added into the backing). Now, WPCT was able to be wrapped and shrunk around any size pipe which product a LOT more flexibility to the industry.
Now here we are nearly 50 years later, and WPCT and TPS are still cornerstones of the Seal for Life corrosion prevention catalog of products.
TPS is availabe in 18" lengths. WPCT is available in 11", 17", 24" and 34" widths (customs available as well). Would love to chat with you about your upcoming project!
