WPC100M In Stock!

 Covalence WPC100M - In Stock!

Covalence WPC100M is the mastic shrink sleeve with the highest temperature rating

     WPC100M was invented back when Raychem was the name of the manufacturing company.  Using a high temp butyl mastic sealant and an irradiated polyolefin backing, WPC100M very quickly became the coating of choice for a number of higher temperature pipeline applications.  

    Rated for use on pipelines operating at up to 176F when the sleeve will see direct contact with soil or the ocean floor, WPC100M has the added feature that in cases where a pipeline is insulated or concrete coated; the sleeve is rated for use at up to 212F.  

     Beyond all of that, WPC100M was an ideal offshore field joint coating is it required only wire brushed surface preparation (the butyl mastic is very aggressive).  This allowed for VERY fast installations and offshore; time is money.

     Available in widths of 11", 17", 24" and 34" --- WPC100M can also be available in custom widths (less than 34").  

     We do stock WPC100M in our warehouse and can have sleeves ready to ship within hours.  As of this moment, I have several thousand feet of WPC100M ready to go at a moments notice!  Reach out for more information:  steve@jsicoatings.com  936/321-3333

WPC100M Shrink Sleeve Widths

 

In What Widths is WPC100M Available?

     WPC100M is a wrap around shrink sleeve manufactured by Seal for Life and sold through their Covalence brand (formerly Raychem).  WPC100M uses a butyl mastic sealant to prevent corrosion on field joints of pipelines that will operate at elevated temperatures.  When the shrink sleeve will be in contact with soil, WPC100M is rated for use at 176F.  If the WPC100M shrink sleeve is not directly exposed to soil (concrete coated pipe; insulated line; etc) then the sleeve is rated for use at 212F.  

Historically, WPC100M founds its primary home protecting offshore pipelines.  There are many onshore applications for it as well. 

     So, how do you know what the optimal sleeve width is for your specific project?  That is a fairly simple answer.  The sleeve needs to be wide enough to coat the bare steel of the field joint and overlap onto the adjacent factory applied coating (both sides) by at least 3" per side.  So if you have 4" of bare steel cutback at your field joint, and you then need 3" of overlap on one side of the weld and 3" of overlap on the other side of the weld; you would need a sleeve that is AT LEAST 10" wide (closest standard is 11"). 

     Notice the 'at least'.  There are many cases where a company realizes they could use an 11" wide shrink sleeve, but they choose to use a 17" or 24" wide sleeve instead to increase the area of their seal.  

     So what widths are stocked on a regular basis at JSI?  At any given moment, I may have ~20,000 feet of the following various sizes:

• WPC100M 11x100 (11" wide)
• WPC100M 17x100 (17" wide)
• WPC100M 24x100 (24" wide)
• WPC100M 34x100 (34" wide)
