Steel pipe is a hollow steel, a large number of pipes used as a channel to transmit kinds of fluid, such as oil, gas, water, gas, steam and so on, in addition, when the bending and torsional strength are same, they are light in weight compare to others, so it is also widely used in the manufacture of mechanical components and structures, and also used in producing a variety of conventional arms, barrel, shells etc.

In some ways, we can classify steel pipes into certain types, like seamless steel pipes and welded steel pipes. According to section, there are circular and shaped tubes, circular steel pipes are used more widely. But there are still square, rectangular, semicircular, Hexagon, triangle, Octagon and other special-shaped steel pipes.

For seamless steel pipes, firstly, the more thicker the thickness is, the more economic and practical the pipe are. Besides, the wall is more thin, the processing costs will rose by a wide margin.; secondly, the process of pipes decide the limitations of them, General seamless steel pipes have a low precision, the thickness is steady, and light degree of tube appearance is low, and there are spot within appearance. It is not easily removal; thirdly, its detection and the reforming must be made by offline processing. So it reflects its superiority in the mechanical structures materials which are posed in the high pressure and strength.

For welded steel pipes, firstly, they are a continuous online production, the more thicker the thickness is, the more lager the investment in welding equipment is, the less economic and practical the pipes are. The process decisides its pros and cons, welded steel pipes have a high precision, and the thickness is steady, pipe looks high luminous (the pipes’ level determines the surface brightness of the plate), which can be made any size. Therefore, it shows economy and beautility in the application to transmit high precision and low pressure fluid.
