1. Good structure: enhanced tube skeleton using high-performance adhesive composite steel tube and rubber layer as a whole, use special technology through professional vulcanization to composite vulcanization molding, owns advantages of both steel pipe and rubber.

2. Good wear-resisting performance, long service life: abrasion value test results generally within the scope of 0.03-0.20 cm3/0.20 km, is about 3 to 5 times that of the plastic, 4 to 6 times higher wear resistance than steel tube.

3. High strength, high impact resistance: rubber elastomer is low density (1.2 g/cm3), light weight, good vibration absorbing performance and excellent mechanical shock resistance, high strength, good rigidity, do not produce creep, shock resistance, seismic, water hammer resistance is strong, easy to transport, install and maintain.

4. Excellent anti-corrosion performance: it can resist majority of corrosive medium and organic solvent, such as polyethylene, polypropylene, nylon, ABS plastic, etc.

5. Wide temperature adaptation range: desulfurization lining pipe, elbow, tee can be used in 40 ° C to + 140 ° C for a long time, lining rubber will not steel disengaged with temperature change.
