The high-chromium alloy wear-resistant pipe is formed by a centrifugal moulding process to form a high-chromium cast steel lining, which has the wear resistance of high-alloy cast steel, and can withstand pressure and high mechanical properties.
The bi-metal lined high-chromium wear-resistant alloy pipe series adopts the bi-metal composite casting process, the outer wall of the pipe is made of ordinary carbon steel pipe, and the inner lining is made of high-chromium wear-resistant alloy. It mainly has the following advantages:
- The high-chromium wear-resistant alloy tube with bimetal lining has high wear resistance. The hardness of high-chromium cast iron is M7C3 carbide, which has high toughness and high hardness, so it has good wear resistance.
- The bimetal lined high-chromium wear-resistant alloy tube has high bearing pressure and is suitable for use at any pressure level.
- The bimetal lined high-chromium wear-resistant alloy tube has good thermal vibration resistance. The thermal expansion coefficients of the inner layer and the outer layer of the main product are equivalent. For the working conditions with rapid temperature changes and frequent changes, no damage to the inner layer will occur. fall off and fail.
- The bimetal lined high-chromium wear-resistant alloy pipe is easy to install and use, and is installed by flanges, quick joints, and direct welding.
At the same time, bimetal lined high-chromium wear-resistant alloy pipes are widely used in many aspects, including hydraulic slag conveying systems and slurry conveying with larger particle sizes; coal powder conveying systems in thermal power plants, wet and dry ash conveying pipes, Stone coal system; various mine material transportation, etc.
