Seamless Steel Pipe

A seamless steel pipe is a circular pipe having a hollow section and no seams around it. The seamless steel pipe is made of carbon steel, alloy steel, stainless steel ingot or solid tube blank, and then is made by hot rolling, cold rolling or cold drawing. Seamless pipes, are considered superior to welded pipes as they are built using monolithic steel billets, with intrinsic mechanical strength, without seam welds.

Characteristics of seamless steel pipe

Seamless steel pipe for the use of engineering and construction is very widely, it is a hollow steel strip no seams, it is mainly used to transport liquids pipelines, different look and general steel,one of those heavy type steel, it has a strong resistance to corrosion, resistant to general corrosion.
Will not rust, this performance makes seamless steel tubes extend the life, the most important is that it is very clean and no toxins.
Compared with other plastic seamless steel pipe having strong mechanical resistance, impact regardless of how high a temperature is not interested in the use of seamless steel pipe, it is mounted and the other pipe is the same, can replace other piped water and other liquids.

Characteristics of seamless steel pipe are as follows:

  • High precision can do small batch production.
  • Smaller diameter.
  • Weldability strong, high compression capability.
  • Steel pipe superior performance, relatively dense metal.
  • The steel cross area is more complex.
  • High precision cold drawn products, good surface quality.

Tensile strength

The tensile strength of a material is the maximum amount of tensile stress that it can accept before failure (such as breaking or permanent deformation).
