Products Metallurgy bimetallic wear resistant pipe is nearly two decades of rapid development of a foreign project pipeline, varieties, many functions, superior performance. Cooperation with well-known institutions to develop wear-resistant bimetallic tube metallurgy, centrifugal casting by bimetal coating material can be combined with metallurgical substrate interface and excellent quality, widely used in mining, power, chemical, and metallurgical coal industry. Bi-metal wear and metallurgical process characteristics in the production process pipe straight centrifugal casting technology, which is a fusion of the two metals are formed in the liquid state, to achieve a true metallurgical bonding purposes, combined interlaminar shear strength than the body metal, the full realization of the grassroots and mechanical wear layer complementary; elbows, tees, reducers and other fittings using vacuum suction casting EPC composite technology, advanced its technology to effectively solve complex problems can not bend, bend and other various special-shaped pipe can do the whole complex, does not change the material flow in the bend of the track, greatly reduce material handling resistance. In the material of choice centrifuge tube outer wall carbon steel pipe to ensure that the wear resistance with high mechanical strength and impact resistance; lining wear layer to choose our own research and development of anti-wear steel series, the steel major Add a Cr-Ni-Mo-Cu-RE alloy, after quenching and tempering heat treatment process, so that the steel has both a strong wear and corrosion resistance properties, have high mechanical strength and impact resistance. My company's entire process is a national initiative to fill the gaps in the industrial pipeline corrosion resistant, and has reached the international advanced level, has been widely used in mining, metallurgy, coal, electric power industry, is an ideal wear-resistant pipes .
