What is the difference between seamless steel pipe and welded steel pipe?
At present, the steel pipes used in our daily life are divided into two types: welded steel pipes and seamless steel pipes. The difference between these two steel pipes can be analyzed from three aspects:
1. In appearance, the difference between seamless steel pipe and welded steel pipe is that the inner wall of the welded pipe has welding ribs, while the seamless steel pipe does not.
2. The pressure of the seamless pipe is high, and the welded pipe is generally about 10MPa. Now the welded pipe is seamless.
3. The seamless steel pipe is formed at one time during the rolling process. Welded steel pipes need to be rolled and welded, and spiral welding and straight welding are generally used. Seamless pipes perform better and of course cost more.
