Features of Polyurethane lined anticorrosion pipe steel pipe: 1, anti-aging The carbon nanomaterials used in polyurethane is a leading international business technology, through a certain proportion and complex process makes both complementary strengths and weaknesses, polyurethane material aging rate in 50 years does not exceed 0.26%. 2, the optimal impact and abrasion resistance Due to polyurethane lined has better elastic, when the medium subjected to impact polyurethane is forced to compression under the action of external force, polyurethane restitution after external force disappears, this kind of way greatly reduces the wear that directly strong scour to inner wall of pipeline by the medium, its wear life is ten times of the pipe. 3, Anti-fouling: Polyurethane elastomer liner having a symmetrical molecular structure, it do not form on the slurry Ca2 +, Co32-, HCO3, OH plasma suction effect, do not form scale layer, with a smooth inner surface, good elasticity, can prevent the adhesion of fouling layer, so it has better scaling, slow performance scale 4, Small running resistance: Smooth and transparent surface of the liner, an absolute roughness of the inner wall of 0.082, can reduce operating costs. 5, good combined Polyurethane lined with steel pipe tightly, using a unique process, casting polyurethane elastomer with steel up to 100% of the binding, the unique overall flanging process, does not appear to fall off, tearing off the air and local.
