Product Desciption

Pipeline Field Joint Heat Shrink Sleeve for 3LPE Coating Steel Gas Oil Water Supply Pipe

INTRODUCTION
PE heat shrinkable sleeve has a two-layer structure, it is composed of radiation cross-linked polyethylene backing and special heat melt adhesive. The shrink sleeve should be applied together with non-solvent two component epoxy primer for field joint coating for steel pipeline.
Heat melt adhesive has good bonding with PE backing, steel pipe and epoxy primer. By heating PE back shrinks, adhesive layer melts, the sleeve closely wraps around the pipe joints. It forms together with the epoxy primer a firm and continuous anti-corrosion body, which is similar to the 3-layer anticorrosive coating in factory conditions. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.

Application area:
It is mainly used for field joint coating, wrapping around pipes, anti-corrosion of kinds of pipe joints, and repairing pipes.
For example Oil and gas pipe, PU insulation pipe, 3LPE/2LPE steel pipe.

Field joint coating of steel pipe with 3LPE coating

Feature of heat shrinkable sleeve HSD:
1.fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosive performance,
4.long service life

5.using pure PE material and imported adhesive for ensuring the quality
