TPSM

Tubular heat‑shrinkable sleeve for corrosion protection of welded pipe joints in distribution lines. Two layers: a visco‑elastic mastic sealant and a cross‑linked HDPE backing. The sleeve is slid onto the pipe before the joint is made, then torch‑shrunk onto the cleaned and preheated surface with no primer. As it shrinks the sealant flows evenly and fills surface irregularities. The dimpled backing disappears at the right temperature, so the joint can be inspected afterwards.
