Cold drawn steel pipe factory
Cold drawn steel pipes have become core materials in fields such as mechanical manufacturing and automotive industry due to their high precision, excellent mechanical properties, and wide applicability.
Cold drawn steel pipe refers to seamless steel pipes produced through cold drawing processing technology. This process is to pull the hot rolled or extruded capillary tube through a specific mold at room temperature to achieve the predetermined outer diameter and wall thickness, while improving its surface quality and mechanical properties. Compared with hot-rolled pipes, cold drawn pipes usually have the characteristics of high dimensional accuracy, good surface smoothness, and superior mechanical strength.
Core performance characteristics and application fields of cold drawn steel pipes
Based on its unique processing technology, cold drawn steel pipes exhibit various advantages, which support their wide application.
1. High precision and excellent surface. The cold drawing process can produce steel pipes with a very small tolerance range for outer diameter and wall thickness, and the smoothness of the inner wall is also better than that of hot-rolled pipes.
2. Excellent mechanical performance. Through cold deformation processing and subsequent heat treatment, the tensile strength and yield strength of cold drawn steel pipes are usually higher than those of hot-rolled pipes of the same material, with better comprehensive mechanical properties and the ability to withstand higher pressures or loads.
3. Wide applicability. By adjusting the process parameters, cold drawn steel pipes of different specifications, materials, and performance levels can be produced to meet diverse needs.

Heavy Forging Press Capacity
Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat Treatment Capability
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
Heavy Shaft Machining
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Ring Forging Machining
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
Cylindrical Forging Machining
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Inspection & Testing
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Packing & Delivery
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
