Seamless Pipe

The seamless steel pipe is made by perforating the whole round steel, and the steel pipe without weld seam on the surface. It is mainly used as high-precision structural steel pipes for petrochemical industry, boiler pipes, automobiles and aviation.

Seamless tubing can be made from any of several alloys and metals, such as carbon steel, stainless steel, molybdenum, or tungsten. Seamless pipes are used in those industrial applications that require the highest safety requirements. To produce seamless steel pipes, the solid block is pierced with a piercing plug before the pipe is drawn to the desired size.

Some of the differences between seamless and welded pipes are:

Seamless pipes are extruded and drawn from billets, while welded pipes are produced from roll formed and welded strips.

Due to the higher range of security offered by seamless pipe, it is more expensive than welded pipe.

Seamless pipes are available in relatively short lengths, while welded pipes can be manufactured in longer continuous lengths.

Seamless pipe generally does not show any signs of corrosion until and unless it is subjected to a highly corrosive environment, whereas in welded pipe the welded area is more susceptible to corrosion attack.

The welded area is considered to be inhomogeneous, so it exhibits different ductility and lower corrosion resistance, as well as larger dimensional changes. Seamless pipes eliminate any such problems and thus offer high corrosion resistance.
