Seamless steel tube has a hollow section, a large number of which are used for conveying fluid, such as crude oil, natural gas, coal gas, water and some solid materials, etc. Compared with solid round steel, when the torsional strength is same, the weight of the seamless steel pipe is relatively light, so it is a kind of economical steel, which is
China Hot Rolled/Cold Drawn Seamless Steel Pipe Low using hot rolled steel pipe billet to make heating and piercing, elongating, sizing and stranghtening, cooling, finally hollow bars finished, this is the type most commonly used. Because it is hot rolled, so cost is lowest, but it is suit for large quantity, for small quantity, have to make cold drawn or round bar piercing. size:outer diameter 32mm- 499mm , wall thickness 4mm- 80mm
