Description
Wear tube transport has been in power, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries, and has been developing rapidly. When the abrasive material in the wear-resisting pipe is used for grinding large materials (such as ash, coal powder, mineral powder, etc.), there is a problem of wear and tear, especially the curve bending of the bend pipe is faster. When it carries a strong corrosive gas, liquid or solid, easily was corroded and quickly destroyed. When conveying materials with high temperature, the problem of using heat resistant steel tube is very expensive. After the wear tube is listed, these problems are solved.
