The polyethylene repair patch is a kind of radiation cross-linked polyethylene anti-corrosive repair piece specially designed for buried or overhead steel pipeline weld anti-corrosive patching and insulation pipeline insulation resistant patching.

This product is heated during construction to melt the adhesive layer and paste the broken pipe surface, forming a continuous and tight anti-corrosion system with the original pipe anti-corrosion layer, which can resist soil stress, hydrostatic pressure, cathodic stripping, chemical corrosion and mold erosion and other corrosion behavior. Polyethylene repair patch is mainly used for pipeline polyethylene external anti-corrosion layer in transport, inspection and construction process caused by the repair of damage, such as local area of the point injury, line scratches and other small area damage.
