Wear-resistant pipe [1] mainly includes wear-resistant elbow, straight pipe, tee, size of the head, square and round section, reducer pipe and other structural components, mainly used for pneumatic, pumping slurry and other materials conveying pipeline. Due to the high hardness of the conveying medium, fast flow rate, large flow rate and other characteristics of the conveying medium for a long time to continue to produce impact on the pipe wall, abrasion, corrosion and other fatigue of the pipeline resulting in gradual wear through.

According to the different wear conditions, wear-resistant pipe lining also have different material selection. There are lined with wear-resistant ceramic pipe (lined with aluminum oxide, silicon carbide, zirconium oxide, silicon nitride, cylon, aluminum nitride, boron nitride, etc.); wear-resistant alloy pipe; tortoiseshell mesh wear-resistant pipe fittings; steel-orbital wear-resistant pipe; steel-plastic wear-resistant pipe; wear-resistant cast stone pipe; wear-resistant self-spreading composite pipeline; wear-resistant rare-earth alloys such as pipe.

Conveying has been all over the electric power, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries, and high-speed development. When the wear-resistant pipe conveying abrasive materials (such as ash, coal powder, mineral powder, tailings, cement, etc.), there is a wear-resistant pipe wear fast problem, especially the elbow pipe wear faster. When the wear-resistant pipe conveys gases, liquids or solids with strong corrosion, there is a problem that the wear-resistant pipe is corroded and quickly destroyed. When the wear-resistant pipe conveys materials with high temperature, there is the problem of using heat-resistant steel pipe is very expensive. These problems were solved when the wear-resistant pipes came on the market. Wear-resistant pipe is widely used in severe wear and tear of mine filling material, ore concentrate and tailings delivery, coal-fired thermal power plants to send powder, slag, ash conveyor wear-resistant pipe is also very suitable. Wear-resistant pipe is the ideal wear-resistant pipe for conveying strongly corrosive acids, alkalis, salts and abrasive solids and liquids. Wear-resistant pipe is very safe and reliable to be used in high-temperature corrosion, high-temperature abrasion or high-temperature melting and erosion.
