Wear resistance of seamless steel pipes

Date:2022-01-19View:567Tags: seamless steel pipes

According to the understanding of seamless pipe manufacturers, seamless steel pipes are made of a single piece of metal and have no joints on the surface. Then it is made by hot rolling, cold rolling or cold drawing. Different from other steel pipes, seamless steel pipes have strong corrosion resistance, stability and durability, adapt to different uses, and have a strong application in the construction process.

It is not limited by natural conditions during the installation process, and has excellent wear resistance: the thickness of the wear layer of the seamless pipe is 3-12mm, the hardness of the wear layer can reach HRC58-62, and the wear resistance is 15-20 times that of ordinary steel plates. The above is more than 5-10 times the performance of low-alloy steel plates, 2-5 times more than the wear resistance of high chromium cast iron, and the wear resistance is much higher than that of spray welding and thermal spraying.

The seamless steel pipe is a double-layer metal structure. The wear-resistant layer and the base material are metallurgically separated. The separation strength is high. It can absorb energy in the process of being impacted, and the wear-resistant layer will not fall off. Under strong working conditions, this is beyond the reach of cast wear-resistant materials and ceramic materials. The alloy carbide of seamless steel pipe has strong stability at high temperature.

Wear-resistant steel plates can be used within 500°C, and other special requirements can be customized and produced, and can be used within 1200°C; ceramics, polyurethane, molecular materials, etc. With the posting method, wear-resistant materials cannot meet such high temperature requirements. The base material of seamless steel pipe is ordinary Q235 steel plate, which ensures that the wear-resistant steel plate has resistance and plasticity, and provides the strength of opposing external forces. It can be connected with other structures by various methods such as welding, plug welding, and bolt connection, and the connection is firm and not easy to fall off. , the connection method is more than other materials.
