Carbon steel pipes are made from ingots or solid round bars by piercing to form rough pipes, which are then hot rolled, cold rolled, or cold drawn to produce the final tubing. Below is a detailed introduction to carbon steel pipes:
Carbon steel pipes are mainly divided into two categories: hot-rolled carbon steel pipes and cold-rolled (drawn) carbon steel pipes.
Hot-rolled carbon steel pipes: Including general steel pipes, low-medium pressure boiler pipes, high-pressure boiler pipes, alloy steel pipes, stainless steel pipes, oil cracking pipes, geological steel pipes, etc.
Cold-rolled (drawn) carbon steel pipes: In addition to certain categories of hot-rolled carbon steel pipes, it also includes carbon thin-walled pipes, alloy thin-walled pipes, stainless thin-walled pipes, and special-shaped pipes.
Select the appropriate carbon steel grade for the intended use and ensure the raw materials are free of defects. Cut the material to the specified dimensions using a sawing machine or cutting equipment. Shape the cut steel into the approximate form of carbon steel pipes through operations such as bending and rolling. For multi-segment steel sections that require connection, use manual arc welding or submerged arc welding processes. Modify the internal structure of the carbon steel pipes through heating and cooling to enhance their performance. Treat with processes such as rust removal, painting, or galvanizing to boost the corrosion resistance and aesthetics of the carbon steel pipes.
High strength, toughness, and hardness: Carbon steel pipes can withstand high pressure and are not easily deformed or fractured under twisting or bending.
Excellent corrosion resistance: Carbon steel pipes can withstand the erosion of various corrosive mediums under specified conditions. However, compared to stainless steel pipes, their corrosion resistance is poorer, and anti-corrosion treatment is required when used in damp or corrosive environments.
Low raw material cost: The raw material price of carbon steel pipes is relatively low, which also keeps the manufacturing cost low, making them very common in various fields.
Carbon steel pipes are widely used due to their unique physical and chemical properties, primarily in the following fields:
Support and drainage pipes commonly used in building structures. Play a critical role in the exploration, transportation, and processing of oil. Pipe systems for conveying chemicals, liquids, and gases. Widely utilized in urban water supply and drainage systems. Used in the manufacturing of various mechanical equipment and components, such as cars, ships, planes, and construction machinery.
