High mechanical strength,anti-aging capablity,high environmental stress performance is good,adhesive outstanding performance.

CRP is specifically for the polyethylene coating of steel pipline design and development of mending radiation crosslinking mending repair pieces,it is made of radiation crosslinked polyolefin composite substrate and special seals made of hot melt.CRP in the construction of the heating,making the special hot melt coating to melt,and make close adhsive wound site,and the original pipe outer coating of polyethylene to form one,uniform coating in the pipe surface to form a continuous close preservative system can resist soil stress,hydrostatic pressure resistance, anti-cathode stripping, anti-chemical corrosion and erosion, and other corrosion-shaped mold is for the steel pipe to provide long-term ,effective protection.CRP is mainly used for corrosion and three layers of polyethylene pipe and PE anti-corrosion coating in the transportation,inspection and construction process of repairing the damage caused,such as the local area point of injury,the line scratch a small area of less than 100mm square injury.
