Product Description

Radiation Cross-Linked Pipeline Field Joint Girth Weld Corrosion Protective Coating Heat Shrink Tape
 

INTRODUCTION
The heat shrink tape is composed of cross-linked polyethylene back and special heat melt adhesive. It is applied together with Solvent-free two component epoxy primer.
The heat melt adhesive has good bonding with PE back, steel pipe and epoxy primer.
When heating the sleeves, the PE back shrinks, the adhesive layer melts and closely wraps around pipe joints. It can form together with epoxy primer a firm and continuous anti-corrosion body. It is resistant to corrosion, wear, impact, UV and aging, and is easy to be applied.

Our company has been working on this product for 18 years. We use high-quality raw materials for the production of Heat Shrink Sleeves, which can provide superior corrosion protection for the pipeline joints.

APPLICATION AREAS
The heat shrink tape is mainly used for sealing and corrosion protection of pipeline joints.
For example Oil and gas pipelines, Pre-insulated pipes, water transmission pipelines.

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

 



Features of our heat shrinkable sleeve:
1.fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosion performance,
4.long service life
5.using pure PE material and imported adhesive for ensuring the quality
