Base Pipe Thickness: Customizable
Silicon Carbide Thickness: ≥15mm
Application Scope: Suitable for power, steel mill slag flushing, coal chemical industry, mining, and conveying pipelines.
Silicon carbide wear-resistant pipes (elbows, tees, reducers) consist of three layers from inside to outside: silicon carbide, filling layer, and steel pipe. The inner silicon carbide layer uses silicon carbide particles as the main raw material, adding various chemical raw materials and antioxidants, with SiO2 micropowder as the high-temperature bonding phase. It is integrally sintered at a high temperature of 1500°C, fired into pipe shapes, and then embedded into steel pipes with high-temperature materials for filling, to manufacture silicon carbide composite wear-resistant pipe fittings.
