Pipe is a hollow steel bar, a large number used for channels of transmitting fluids such as oil, gas, water, gas, steam, etc. In addition, when bending, torsional strength is same,the weight is lighter, so it is widely used for the manufacturing of mechanical parts and engineering structures. Also used in producing all kinds of conventional weapons, the barrel, shells and so on.
Seamless steel pipe  is made by steel ingot or solid tube by the piercing for capillary,and then by the hot-rolled, cold-rolled or cold call.
Specifications of seamless steel pipe is said by a diameter * wall thickness in millimeters. Seamless steel pipe includes hot-rolled and cold rolled seamless steel pipe.
