Product Description

PE Heat Shrink Shrinkable Tape for Steel Pipe Girth Weld Field Joint Corrosion Protection

Product introduction
PE backed heat shrinkable wraparound sleeve (HSS) for pipeline is composed of radiation cross-linked polyethylene backing and special heat melt adhesive.
There is also a reinforced type, in which a glass fiber reinforced layer is added to the backing for better effect.
When heating the heat shrink sleeve, the PE backing shrinks and the adhesive melts. The sleeve closely wraps around the pipe. The heat shrinkable sleeve (HSS) forms a firm and continuous anti-corrosion body, which is resistant to corrosion, wear, impact, UV and aging.



Application:
1. Field joint corrosion protection for gas oil steel pipeline, water supply pipeline.

2.Corrosion protection pipes, bends, fittings of pipeline.

3.Anti-corrosion and seal for heating pipeline

4.Connecting and seal for corrugate pipes (sewage pipe, waste pipe, drain pipe).

Feature of our heat shrinkable sleeve:
1.Fast shrinkage speed
2.Good waterproof performance
3 Good anti-corrosive performance
4.Long service life
5.High-quality PE material and adhesive

Executive Standard
Products comply with national and international standards GB/T23257-2009, SY/T4054-2003, EN12068, DIN30672 etc.
