HDPE Hollow Wall Pipe for sewage pipeline joint PE Heat Shrinking Sleeve
Heat shrinkable sleeve-HSSC-1
Hollow Wall Pipe Heat Shrinking Sleeve PE Sleeve Cover (2 layers), which are developed and manufacture by Qingdao Huashida machinery Co., Ltd for anti-corrosion of pipeline, are the composition of radiation cross-linked polyethylene backing and high shearing strengthen melt adhesive, and have the function of shape memory. The hot melt adhesive is squeezed into the joint by the shrink power to form a perfectly sealed surface, after being heated. HSSC-1 is compatible with standard pipe coating, also can be used for coating bare, replacement pipe section and large radius bends. The system is designed to be applied with minimum preheating and is ideal for large diameter wastewater pipe.
Feature
Fast shrinkage speed, good waterproof performance, good anti-corrosive performance, long service life, convenient transportation and fast construction. The product are ideal material for corrosion prevention and insulation.
Application scope
It's mainly used for HDPE corruagated pipe network, metal inforced spril pipe connecting, chemical pipes and sewage pipes etc.
