Professional Manufacturer of PE Cross-Linked Heat Shrink Wraparound Tape Production Lines for Field Joint Coating of 3PE Fbe Coated Steel Pipes

Product Description

Professional Manufacturer of PE Cross-Linked Heat Shrink Wraparound Tape Production Lines for Field Joint Coating of 3PE / 2PE / FBE Coated Steel Pipes

 

Product Description

The heat shrink tubing is composed of cross-linked polyethylene back and special heat melt adhesive.
The heat melt adhesive has good bonding with PE back, steel pipe and Fusion bonded epoxy (FBE layer). When heating the sleeves, the PE back shrinks, the adhesive layer melts and closely wraps around pipe joints. It can form together with FBE 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 tubing 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
