What is the purpose of carbon steel pipe？
Carbon steel pipes are a type of metal pipe with high strength and corrosion resistance, and its main components are carbon and iron. Carbon steel pipes are widely used in industries, construction, automobile manufacturing, petrochemicals, etc.
First of all, carbon steel pipes are widely used in the field of construction, for the support and framework of building structures, such as stair handrails, guardrails, steel structure frames, etc. Carbon steel pipes have high strength and elasticity, can withstand large weight and pressure, and have good plasticity, which can meet the various needs of building structures.
Secondly, carbon steel pipes also have important uses in the industrial field for the transportation of liquids, gases and solid particles. For example, in the fields of oil, natural gas and chemical industry, carbon steel pipes are widely used to transport oil and gas, chemical raw materials and finished products, such as oil pipelines, natural gas pipelines, chemical pipelines, etc.

Carbon steel pipes are a kind of metal pipes with high strength and corrosion resistance, and their main components are carbon and iron. Carbon steel pipes are widely used in the fields of industry, construction, automobile manufacturing, petrochemicals, etc.
In addition, carbon steel pipes also play an important role in the field of automobile manufacturing, and are used to manufacture automobile parts and structural parts, such as engine exhaust pipes, wheel hubs, frames, etc. Carbon steel pipes have high strength and toughness, which can meet the requirements of automobile manufacturing for parts.
In addition, carbon steel pipes are also widely used in the manufacture of mechanical equipment and tools, such as drilling rigs, punching machines, excavators, cranes, etc., as well as the manufacture of furniture, electrical appliances, heating equipment, etc. Carbon steel pipes have good machinability and corrosion resistance, and are suitable for the manufacture of various mechanical equipment and parts.
Carbon steel pipes are divided into 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 (drawn) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes, and special-shaped steel pipes. 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 steel 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 pipes: are made by hot-rolling or cold-rolling high-quality carbon steels such as 10, 20, 30, 35, 45, low-alloy structural steels such as 16Mn, 5MnV, or alloy steels such as 40Cr, 30CrMnSi, 45Mn2, 40MnB. Seamless pipes made of low-carbon steels such as 10 and 20 are mainly used for fluid delivery pipelines. Seamless pipes made of medium-carbon steels such as 45 and 40Cr are used to manufacture mechanical parts, such as load-bearing parts of automobiles and tractors. Generally, carbon steel pipes must ensure strength and flattening tests. Hot-rolled steel pipes are delivered in hot-rolled or heat-treated states; cold-rolled steel pipes are delivered in heat-treated states.
