How Do I Coat a Long Length of Pipe or a Bend with a Shrink Sleeve

     It is fairly common that someone in the field needs to coat a length of pipe; or needs to coat an uncoated bend.  In such a case, we typically recommend that they lobster back the shrink sleeves down the length of the pipe.  This is a fairly simple application.  After the pipe has been cleaned (to whatever standard is required based on the sleeve material selected); the pipe is preheated (again; per manufacturers suggested installation methods) and then the first sleeve is installed; overlapping the existing factory applied coating by at least 3" (possibly 2" depending on end user specification).

     Next; the adjacent uncoated pipe is preheated; a new sleeve is wrapped (overlapping the previous sleeve by at least 3") and shrunk.  Shrink; preheat and repeat.  It's quite simple.  I've seen lengths of pipe as long as 600 feet coated in this manner and it was all done quickly and easily.  Sleeves are generally available in 11", 17", 24" and 34" widths and some combination of these can be used to coat most long radius bend and any length of uncoated pipe.
