The wear of seamless stainless steel elbow has always been a factor affecting civilized production. With the continuous development of science and technology, materials have also been innovated, and materials such as cast stone, cast steel, alloys, and centrifugal cast composite ceramics have appeared one after another. Among them, the pipeline lining alumina ceramics has become a widely used wear-resistant material due to its high wear resistance, high hardness, oxidation resistance, good corrosion resistance and extremely high resistance to high and low temperature strength. It has become a widely used wear-resistant material, occupying the world's special ceramics market. The share (wear-resistant material) is about 80%.

Uses of seamless stainless steel elbow:
　　1. Seamless stainless steel elbow is suitable for pipeline systems in oil, natural gas, chemical, hydropower, construction and boiler industries. No tube blank is needed as raw material, which can save the cost of tube making equipment and molds, and can reach any large diameter and relatively thin wall thickness carbon steel elbow.
　　 2. The manufacturing cycle can be shortened, and the production cost is greatly reduced. Because it does not require any special equipment, it is especially suitable for on-site processing of large carbon steel elbows. The blank is a flat plate or a developable curved surface, so the blanking is simple, the accuracy is easy to ensure, and the assembly and welding are convenient.
