Seamless steel ingot is made ​​of perforated or solid tube capillary tube, and then by hot-rolled, cold-rolled or cold-call is made. Seamless hollow sections, a large number of channels for transporting fluids, steel pipe and solid steel bar, etc. compared to the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding.

API seamless pipe will often be categorized based upon the way in which it was manufactured. Two manin methods of manufacturing api seamless pipe exist, cold drawing and finishing, cold drawing refers to a tube-building method in which the tubing is drawn, or shaped at room temperature. this method is good for creating a bettersurface finish, closer tolerances,lighter walls or smaller diameters of tubing. hot finished api seamless pipe is made without the use of any cold finishing, meaning that the seamless pipe is built while the material is extremely hot. Both of these processes are commonly used.
