Product Detail
Heat-shrinkable wraparound sleeve with closure patch mainly used in coating the weld joint of buried steel pipeline.
FRDP Heat-shrinkable wraparound sleeve with closure patch mainly used in coating the weld joint of buried steel pipeline and insulated pipeline.
Wraparound Sleeve for three-layer coated pipes forms excellent adhesion with the surface of steel pipeline, PE-coating; meanwhile, it forms a continuous and firm anti-corrosive system with the surface of the pipeline.
Heat-shrinkable wraparound sleeve with closure patch has strong adaptive capacity to environment and good resistance to mechanical damage. It has good resistance to liquid pressure and bacterium, mildew and other chemical corrosion.
