1, Good wear resistance: because 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.

2, 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

3, Small running resistance: smooth and transparent surface of the liner, the inner wall of the absolute value is 0.082 rough, to reduce operating costs.

4, Good water resistance and stability, good aging resistance: It won't swell in the water like rubber products to affect performance.

5, Good combination: polyurethane tightly lined with steel pipe, and using a special process.
