Product Introduction


Welded carbon steel pipe is a carbon steel pipe made of carbon steel plate or carbon strip steel after being crimped and welded, generally with a length of 6 meters.

The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and specifications, and the equipment investment is small, but in general, the strength of carbon steel welded pipe is lower than that of seamless steel pipe.
