Cold drawn pipe manufacturer
In the metal processing industry, cold drawn pipes are an important industrial material, and their production technology and product quality have received widespread attention. We use specific process technology to cold draw hot-rolled or seamless pipes to produce pipes with higher dimensional accuracy, smoother surface, and better mechanical properties.
Basic principles and characteristics of cold drawing process
*High dimensional accuracy: The cold drawing process is carried out under strict control of the mold, so the outer diameter, inner diameter, and wall thickness tolerances of the pipe can be controlled very accurately, far superior to hot-rolled pipes. This is crucial for mechanical components that require precision assembly.
*Good surface quality: The surface of cold drawn pipes is usually smooth and bright, with fewer defects. However, the surface of hot-rolled pipes has iron oxide scales, which are relatively rough.
*Mechanical performance improvement: The cold work hardening effect during cold drawing can enhance the strength and hardness of the pipe material. Of course, this is sometimes accompanied by a slight decrease in plasticity (such as elongation).
*Can produce thin-walled and small-diameter pipes: Cold drawing process is more suitable for producing pipes with very thin wall thickness or small diameter, which is difficult to achieve with hot rolling process.
The main application areas of cold drawn tube products
*Mechanical manufacturing: used for producing structural components such as hydraulic cylinders, cylinder barrels, various transmission shafts, and precision instruments. These occasions have strict requirements for the dimensional accuracy, straightness, and surface smoothness of the pipes.
*Automotive industry: applied to shock absorber pipes, steering gear rack pipes, some fuel system pipe fittings, etc.
*Textile machinery: used as a substrate for various rollers and shafts.
*Other fields: such as fitness equipment, furniture components, precision piping for some construction machinery, etc.

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.
