Many people can not make a distinction between an ordinary welded steel pipe and seamless steel pipe. In fact, we can conclude these two steel pipe’s difference from their names. Today, ADTOMALL, the leading professional steel pipe supplier based in China is going to help you to understand these two different kinds of steel pipes. 

These two kinds of steel pipes are manufactured in a different process and different technique.

Ordinary welded steel pipe, such as pipe used to transport the water, typically is manufactured by bending a flat plate and then welding it together. You can find weld seam in the surface of the steel pipe, generally thicker diameter spiral weld. The molten steel seamless pipe generally molten through an annular slit and then stretched out the backlog of processing such as molding process, so there is no weld seam on the surface of steel pipe.

Compared with the ordinary welded steel pipe, seamless steel pipe has greatly improved the bearing capacity, it is often being used for high-voltage equipment like hydraulic equipment such as piping connections. Ordinary welded steel pipe is weak in the structure due to the welding seam on the surface of steel pipes.
