Cangzhou Bohai Pipe Fittings Co., Ltd. has specialized in producing the essential difference between the traditional wear elbow abrasion resistant steel pipe, wear-resistant alloy steel pipe, cast pipe and steel-plastic, steel and rubber tubes. Wear-resistant outer layer is seamless steel pipe inner corundum. Corundum layer hardness up HV1100-1400, equivalent to tungsten carbide cobalt, abrasion than carbon steel pipe more than 20 times higher. Pipelines to resist abrasion wear mainly by sales corundum wear elbow inner layer a few millimeters thick, which is wear-resistant alloy steel pipe ratio, cast stone pipe both by composition and organization, but also by the thickness wear has been a qualitative leap. Pipe Co., Ltd. Cangzhou Bohai performance advantages of professional production ◆ wear elbow pipe liner wear corundum ceramics (a-AL2O3) wear elbow, Mohs hardness of up to 9.0 equivalent of HRC90 or more, wear life is quenched ten steel or even several times. ◆ long-term normal operation within -50--700 ℃ temperature range. Linear expansion coefficient of 6-8 × 10-6 / 0C wear elbow quotes around about 1/2 of the pipe, has good thermal stability. ◆ smooth inner surface is better than any metal pipe, clear the drag coefficient of 0.0193, running resistance, low operating costs.
