PU Lined ore concentrate conveying pipe is a synthetic material, rubber and plastic between between its function, with high strength, high load bearing, high tear strength, high hardness still has high elasticity and other features, the product convex from excellent wear performance, and its function is a natural rubber abrasion 5-8 times, and also has good corrosion resistance, low temperature resistance, aging resistance, oil resistance, organic solvents, and the metal has good adhesion and function, is a wide range of applications, integrated well-functioning product. PU Lined ore concentrate conveying pipe advantages: 1. PU Lined ore concentrate conveying pipe has high impact toughness. Impact resistance 30% higher than the high pressure hose, make up the shortage of rubber hose and steel pipe. 2. PU Lined ore concentrate conveying pipe has stable performance, low coefficient of expansion, similar to steel, can effectively reduce pressure loss. 3. wear resistance, strong corrosion ability, after long-term use is liable to wipe still bright as new. 4. good combination, polyurethane lined with steel pipe linked closely together, using a special process. Now widely used in the marine, ferrous metal mining, non-ferrous metal mining, non-metallic mineral mines.
