PRODUCT DESCRIPTION
Seamless steel pipes are made of steel ingots or solid tube blanks through perforation, and then hot rolled, cold rolled or cold drawn.
There are two types of seamless steel pipe: hot-rolled steel tube and cold-rolled (cold-drawn) seamless steel pipes.
Hot-rolled seamless steel tubes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, Stainless Steel Pipes, petroleum cracking pipes, geological steel pipes, line pipes and other steel pipes.
In addition to the above-mentioned steel pipes, cold-rolled (cold-drawn) seamless steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Stainless Steel thin-walled steel pipes, and special-shaped steel pipes.
The outer diameter of hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The diameter of cold-rolled seamless steel pipe can reach 6mm, and the wall thickness can reach 0.25mm. Rolling has higher dimensional accuracy than hot rolling.
Generally, seamless steel pipes are made of 10#, 20#, 30#, 35#, 45# and other high-quality carbon structural steels such as 16Mn, 5MnV and other low-alloy structural steels or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other combined steels that are hot-rolled or cold-rolled. rolled. 10#, 20# and other low Carbon Steel seamless pipes are mainly used for fluid conveying pipes. Seamless tubes made of medium carbon steel such as 45, 40Cr are used to manufacture mechanical parts, such as the stressed parts of automobiles and tractors. Generally, seamless steel pipes are used to ensure strength and flattening tests. Hot-rolled steel pipes are delivered in a hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state.
