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.
