Wear resistant steel pipe is also called wear-resistant pipe. It is a steel pipe made by welding a steel plate or a steel strip after being crimped. The wear-resistant pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment, but the general strength is lower than that of seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip continuous rolling production and advances in welding and inspection technology, the quality of welds has been continuously improved, and the variety of wear-resistant pipes has been increasing, and has been replaced in more and more fields. Seamless steel pipe. The wear-resistant pipe is divided into a straight welded pipe and a spiral welded pipe in the form of a weld.
1. Better impact performance
The wear-resistant steel plate is a double-layer metal structure. The wear-resistant layer and the substrate are metallurgically bonded. The bonding strength is high, and the energy can be absorbed in the process of impact. The wear-resistant layer does not fall off, and can be applied to vibration and impact. Under the working conditions, this is not as good as casting wear-resistant materials and ceramic materials.
2. Very good temperature resistance
Wear-resistant steel alloy carbide has strong stability at high temperature. Wear-resistant steel plate can be used at 500 °C. Other special requirements can be customized to meet the requirements of 1200 °C. Ceramic, polyurethane, high Molecular materials and other materials that adhere to the wear-resistant materials cannot meet such high temperature requirements.
3. Very good connection performance
The wear-resistant steel plate base is an ordinary Q235 steel plate, which ensures that the wear-resistant steel plate has toughness and plasticity, and provides strength against external force. It can be connected with other structures by welding, plug welding, bolting, etc., and the connection is firm and not easy to fall off. , more connections than other materials.
