How much do you know about seamless steel pipe? Seamless steel pipe is a kind of round, square, rectangular steel with hollow cross section and no seam around. Seamless steel pipe is made from ingots or solid billets that are perforated to make a burr pipe and then hot rolled, cold rolled or cold dialed.

Nickel is a ferromagnetic metal element with excellent properties such as corrosion resistance, high temperature resistance, oxidation resistance and good ductility. It is widely used in metallurgy, chemical industry, aerospace and other fields. It is an important raw material for the preparation of stainless steel, high-temperature alloys, power batteries and other materials.

Arc welding: it is used for arc welding of straight seam steel pipes. It has good maintainability, good welding high temperature performance, good physical properties, aluminum alloy parts are not easy to burn, high connection index, good welding formability, no slag shell, and smooth surface. At present, the manual argon tungsten arc welding market is mainly used for argon arc welding of 0.5~3mm stainless steel plates.
