Heat shrinkable pressure -sensitive is designed to protecting oil &gas pipeline from corrosion.
Construction: two-layer system
First layer: modified pressure-sensitive adhesive from butyl rubber
Second layer: radiation cross-linked, high density polyethylene, fiber reinforced composite structure.
Feature
→ Suitable for the project of newly built pipe and in-service pipe
→ Short preparation time; only need to remove the vapor in the surface of steel pipe, no demand for preheating
→ It is no need for primer; only need to use wire brush and abrasive tape to clean the surface of steel pipe.
