Product Description

PE Adhesive Two-layer Heat Shrink Tape Oil Gas for Pipeline Girth Welding Corrosion Protective Coating Ce Certificate

INSTRUSTION
PE backed heat shrinkable tape for pipeline is composed of two layers: radiation cross-linked polyethylene backing and special heat melt adhesive. The heat shrinkable sleeve is applied together with a solvent-free two-component epoxy primer to form a three-layer polyethylene anti-corrosion coating (3LPE) , which replicates the structure and performance of 3LPE coating in factory conditions, providing effective and long-term anti-corrosion for the welding joint of the steel pipe.

During installation, the epoxy is applied to the prepared pipe surface and the heat-shrinkable sleeve is immediately wrapped around the joint over the wet epoxy. Heat is then applied to the sleeve which shrinks to form a tight fit around the joint. While curing, the epoxy forms strong mechanical and chemical bonds to the pipe surface and to the copolymer adhesive layer. The radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission.


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

2.Field joint corrosion protection for water supply steel pipeline.

3.3LPE coating repairing.

Feature of our heat shrinkable sleeve:

1. Brand new PE material and adhesive
2. Strict quality control
3. Fast shrinkage speed
4. Good waterproof performance
5. Good anti-corrosive performance
6. Long service life
7. Easy operation
