Product Description

Carbon steel square/round pipe

Carbon steel square pipe is made of steel ingot or solid round steel which is perforated into wool tube and then hot rolled, cold rolled or cold drawn. Carbon steel pipe plays an important role in our steel pipe industry. According to incomplete statistics, existing carbon steel pipe manufacturers in our country about 240 more than 250 sets of carbon steel pipe units, annual capacity of about more than 4.5 million tons. 760,000 tons of oil pipe, accounting for 5.7%; Hydraulic prop, precision pipe 150,000 tons, accounting for 4.3% stainless pipe bearing pipe, automobile pipe 50,000 tons, accounting for 1.4%.

Carbon steel pipes are divided into two categories:
hot-rolled and cold-rolled (drawn) steel pipes.
Hot-rolled carbon steel pipes 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 and other steel pipes.

In addition to general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (rolled) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, and stainless steel pipes. Rusty thin-walled steel pipes, special-shaped steel pipes. The outer diameter of hot-rolled seamless steel pipes is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipes can be up to 6mm, and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipes can be up to 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.

General carbon steel pipe: It is made of hot-rolled or cold-rolled high-quality carbon steel such as 10, 20, 30, 35, 45, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel. Seamless pipes made of 10 and 20 grade low carbon steel are mainly used for fluid transportation pipelines. Seamless tubes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors. Generally, carbon steel pipes must 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.
