Seamless steel pipes are made of a single piece of metal and have no seams on the surface. They are made of steel ingots or solid pipe billets through perforation, and then hot-rolled, cold-rolled or cold-rolled. Seamless steel pipe is different from other steel pipes. It has strong corrosion resistance, sturdiness and durability, and adapts to different purposes. It has strong applicability in the construction process and is not restricted by natural conditions during installation. The details are as follows :
1. Excellent wear resistance:
The thickness of the wear-resistant layer of the seamless pipe is 3-12mm, the hardness of the wear-resistant layer can reach HRC58-62, the wear resistance is more than 15-20 times that of ordinary steel plates, and the performance of low-alloy steel plates is more than 5-10 times. It is high-chromium cast iron. The wear resistance is more than 2-5 times, and the wear resistance is much higher than that of spray welding and thermal spraying.
2. Excellent impact performance:
The seamless steel pipe is a double-layer metal structure. The wear-resistant layer and the base material are metallurgically bonded. The bonding strength is high. It can absorb energy during impact. The wear-resistant layer will not fall. It can be used for vibration and impact. Under strong working conditions, this is beyond the reach of cast wear-resistant materials and ceramic materials.
3. Excellent temperature resistance:
Alloy carbides of seamless steel pipes have strong stability at high temperatures. Wear-resistant steel plates can be used within 500°C, and other special requirements temperature can be customized to be used under conditions within 1200°C; ceramic, polyurethane, high Wear-resistant materials such as molecular materials cannot meet such high temperature requirements.
4. Excellent connection performance:
The base material of seamless steel pipe is general Q235 steel plate, which ensures the resistance and plasticity of the wear-resistant steel plate, and provides the strength against external forces. It can be connected with other structures by various methods such as welding, plug welding, and bolt connection. The connection is strong and not easy to fall. However, there are more ways to connect than other materials.
5. Excellent processing performance:
Seamless steel pipes can be processed into different standard sizes as required, and can be processed, cold-formed, welded, twisted, etc., which are convenient to use; can be tailor-welded on-site, making repair and replacement work time-saving and convenient, and greatly reducing work intensity.
6. High sex price ratio:
The price of seamless steel pipe is slightly higher than that of general steel, but considering the product life, repair costs, spare parts costs, etc., its performance-to-price ratio is much higher than that of general steel and other steels.
