Corrosion Resistant Wear Resistant Rubber Lined Composite Steel Pipes For Ore Slurries Transfer
Wear-resistant steel pipe is a steel pipe made of steel plate or steel strip after being crimped and welded. The wear-resistant pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment, but its 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 the progress of welding and inspection technology, the weld quality has been continuously improved, and the varieties and specifications of wear-resistant pipes have been increasing, and they have replaced seamless steel pipes in more and more fields. The wear-resistant pipe is divided into straight welded pipe and spiral welded pipe according to the form of weld.
