Seamless Steel Pipe and Welded Steel Pipe Difference

Seamless Steel Pipe

1.Appearance, seamless steel pipe and welded steel pipe have different welding reinforcement on the welded pipe wall

2.Pressure, Seamless pipes require higher pressure during production. Welded pipes usually have about 10 MPa when manufactured.

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.

Carbon Steel Pipe

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.

1. For raw materials, if you want to use stainless steel welded pipe equipment for normal processing, you must pay attention to the problems of the raw materials during transportation or loading and unloading, and try not to cause bumps or scratches.

2. For the used site, the processing site should be stable, and some bedding should be made on the workbench for reprocessing, so as to avoid the phenomenon of scratching the steel pipe on the workbench during operation.

3. When performing cutting construction, for the raw materials to be welded, either shearing or plasma cutting is used. When cutting, use something like rubber for paving.

4. After using stainless steel welding equipment for welding, clean the surface in time to ensure the best construction effect.

5. For the completed welding construction, it is necessary to do a good job in the protection construction of the finished product, try not to touch and other phenomena, so as to effectively avoid secondary pollution.
