Hot Melt Tape 3LPE Pipeline Anticorrosion Heat Shrink Sleeve for Welding Joint Sealing and Coating Protection
PE heat shrinkable sleeve is composed of cross-linked polyethylene back and special heat melt adhesive. Heat melt adhesive has good bonding with PE back, steel pipe, and Fusion bonded epoxy (FBE layer).It is a kind of connecting pipe fitting what is widely used on anti-corrosion, especially on Directly buried pre-insulated pipes field joint. It is made by Polyethylene sheets complex with the electro-fusion wire.
Application area:
It is mainly used for wrapping around the pipe, anti-corrosion of kinds of pipe joints, and repairing pipes.
For example Oil and gas pipe, PU insulation pipe, 3PE/2PE steel pipe.
Feature:
1. According to the pipe corrugated process, the peak valley width usually from 60mm to 80mm, the Narrow tape welding the pipe joint along the cutting edges.
2. Because of various of restrictions, can not guarantee the airproof capability after the pipe joint welded.
3. The best way to weld the joint should use the Hand extruder welding the cutting edges inside of the pipe first, the use the narrow tape welding it from outside.
