Pipeline Field Joint Coating
Product Description
Field Joint Coating Description :
CYG Field Joint Coating- heat shrink wrapping coating consist of cross linked polyethylene backing, hot melt and primer. It is compatible with and made from similar materials as Pre–manufactured Three Layers anticorrosion tape.
CYG Field Joint Coating mainly used in coating the weld joint of buried steel pipeline, Elbow, Tee joints ect.
The steel substrate, FBE primer and plant-applied polyethylene coatings excellently to form a continuous and durable anti-corrosion system on the pipeline.
Field Joint Coating Features:
Excellent adhesion to steel pipe
Long term corrosion protection , Resistant to UV
High chemical resistance under service temperature.
Outstanding electric property and permanent adhesion.
Perfect abrasion resistance performance
CYG Filed Joint Coating- FRDP heat shrink sleeve is Germany DVGW certified.
