Common Material Grades
21CrMo10: A hot-work tool steel and a typical material for heavy-duty pipe molds, offering excellent heat resistance and fatigue resistance.
42CrMo: A commonly used high-strength alloy steel, also referenced in related research and process discussions.
Other tool steels: Such as Cr12MoV and SKD11, used to manufacture components such as molds and rollers in pipe forming equipment.
Typical Dimensions and Weights
Nominal Diameter DN2600: One of the typical specifications for large-scale centrifugal pipe molds in China.
Forging Weight 92.66 metric tons: The weight of the blank forged for a DN2600 pipe mold at a domestic factory, manufactured using a 12,000-metric-ton open-die forging press.
Wall thickness of approximately 175 mm: A typical wall thickness for large, thin-walled, long-sleeve pipe molds, such as those with a length of approximately 9 meters and an outer diameter of approximately 2 meters at the socket end.
Main Application Areas
Ductile iron pipe production: As the core forming mold in the centrifugal casting process, these are critical consumable spare parts in the cast pipe industry.
Steel Pipe and Fitting Manufacturing: Used to produce large, thick-walled, or high-specification steel pipes, fittings, and various types of industrial piping.
Heavy Industry Applications: Supports the manufacturing of large-scale pipe products for industries such as mining, shipbuilding, power generation, petroleum, chemical processing, and defense.

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 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.
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.
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.
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.
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.
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.
