Third, carbon steel rectangular pipe application field
1. Construction: carbon steel rectangular pipe is used as a material to carry the structure in the building structure, and is often used to form a grid or arch support member in the steel frame structure.
2. Mechanical manufacturing: carbon steel rectangular pipe is widely used, such as machine tools, automobiles, trains, rail cars, aircraft, ships and other mechanical equipment can use carbon steel rectangular pipe.
3. Petrochemical: carbon steel rectangular pipe is also widely used in the petrochemical industry, such as chemical equipment, liquid storage tanks, transportation pipelines, etc.
4. Other fields: carbon steel rectangular pipe can also be applied in other fields, such as water conservancy, power, aerospace, national defense, fire protection, environmental protection and other fields.
General carbon steel pipe
General carbon steel pipe: It is made of 10, 20, 30, 35, 45 high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steels by hot rolling or cold rolling. Seamless pipes made of 10, 20 and other low-carbon steels are mainly used for fluid delivery pipelines. Seamless pipes made of 45, 40Cr and other medium-carbon steels are used to manufacture mechanical parts, such as stress-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.
Carbon steel pipes are mainly divided into two categories: seamless steel pipes and welded steel pipes. Seamless steel pipes have the characteristics of high strength and high pressure bearing capacity, and are suitable for harsh environments such as high pressure and high temperature; welded steel pipes have the advantages of low cost and short production cycle, and are suitable for general engineering and civil fields.
