3. The seamless steel pipe is formed once during the rolling process. Welded steel pipes need to be rolled and welded, usually spiral welding and direct welding. The performance of seamless pipes is better, and of course the price is higher.

Steel pipe classification: Steel pipes are divided into seamless steel pipes and welded steel pipes (seamless pipes). According to the cross-sectional shape, it can be divided into circular tubes and special-shaped tubes. Round tubes are widely used, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped tubes.

Seamless steel tube: The seamless steel tube is perforated with steel ingots or solid billets, and then hot rolled, cold rolled or cold drawn. The specifications of seamless steel pipes are expressed in mm outer diameter * wall thickness. Seamless steel pipes can be divided into hot-rolled and cold-rolled seamless steel pipes.
