Pipe Repair Patch

Repair patch /patching piece is a kind of special polyethylene anticorrosive coating for steel pipeline patching patching repair with design developed by radiation crosslinking. It is made of radiation crosslinked polyolefin substrate and special hot melt adhesive sealing compound and into. When heated, Repaid parch in construction makes special hot melt adhesive coating melt, and patching parts tightly bonding, and the original pipe polyethylene anticorrosive layer to form an organic whole, evenly coated on the pipe surface, form a continuous close corrosion protection system. Can resist the soil stress, hydrostatic pressure resistance, chemical resistance and the erosion of the mold, and other corrosion behavior, for steel pipes to provide long-term and effective protection. It is mainly used in polyethylene pipe anticorrosion and three layers of two layers of polyethylene anticorrosive layer outside in the process of transportation, inspection and construction damage repair, such as local area of the injury
