The importance of carbon steel tube

The carbon steel tube is made of steel ingot or solid round steel through perforation to make capillary tube, and then it is made by hot rolling, cold rolling or cold drawing. The carbon steel tube plays an important role in my country's steel pipe industry.

The classification of carbon steel tube

The carbon steel tube is divided into two categories: hot-rolled and cold-rolled (drawn) steel tubes. Hot rolled carbon steel tube is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, geological steel pipe 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 (dial) carbon steel tubes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Stainless thin-walled steel pipe, special-shaped steel pipe. The outer diameter of hot-rolled seamless pipes is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless pipes can reach 6mm and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipes can reach 5mm and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.

General carbon steel tube: It is made of 10, 20, 30, 35, 45 and other high-quality carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold-rolled. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transportation pipelines. 45, 40Cr and other medium carbon steel seamless pipes are used to manufacture mechanical parts, such as the stressed parts of automobiles and tractors. Generally, carbon steel tube is used to ensure the strength and flattening test. Hot-rolled steel pipes are delivered in hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in heat-treated state.

The parameter of carbon steel tube

Do you know about the parameter of carbon steel tube? The carbon steel tube is made of steel ingots or solid tube blanks through perforation to make capillary tubes, and then hot rolled, cold rolled or cold drawn. The carbon steel tube plays an important role in my country's steel pipe industry. According to incomplete statistics, there are more than 240 carbon steel tube production enterprises in my country, more than 250 sets of the carbon steel tube units, and an annual production capacity of about 4.5 million tons. From the perspective of diameter, <φ76, accounting for 35%, <φ159-650, accounting for 25%. In terms of varieties, 1.9 million tons of general-purpose pipes, accounting for 54%; 760,000 tons of petroleum steel pipes, accounting for 5.7%; 150,000 tons of hydraulic props and precision pipes, accounting for 4.3% of stainless steel pipes, bearing pipes and automobile pipes, a total of 50,000 tons. 1.4%. Specifications: The specification of carbon steel tube is expressed by outer diameter * wall thickness mm.
