Thick-walled cylindrical forgings with flanges are integrated, thick-walled hollow forgings that incorporate flanges. They combine the high strength of thick-walled cylinders with the connecting function of flanges and are commonly used in critical applications involving high pressure and heavy loads.
Materials and Grades
Carbon Steel and Alloy Steel: Such as 1045, 4130, 4140, 4340, and 42CrMo4.
Stainless Steel/Corrosion-Resistant Alloys: Used in specialized fields such as nuclear power, for example, grade Z2CN18-10 (an austenitic stainless steel).
Dimension Range
The dimension range of large flanged cylindrical forgings covers a wide spectrum of applications, from standard to extra-large sizes. Specific dimensions and weights depend heavily on the end use and customer drawings.
General Manufacturing Capabilities: Capable of producing forged hollow components with a maximum outer diameter of 4,000 mm, a maximum length of 10,000 mm, and a weight of up to 30 metric tons.
Standard Size Range: Another specification range is an outer diameter of 150–1,500 mm, a length of ≤4,000 mm, and a weight of ≤12 metric tons.
The specific dimensional range for large flanged cylindrical forgings is as follows:
Cylinder outer diameter: 2,000 – 3,500 mm
Cylinder inner diameter: 1,000 – 1,800 mm
Cylinder length: 1,500 – 3,500 mm
Flange outer diameter: 2,100 – 4,000 mm
Flange thickness: 100 – 500 mm
Application Areas
Thick-walled cylindrical forgings with flanges are primarily used in fields with stringent requirements for component integrity, strength, and sealing performance:
Energy and Power: Flanges for nuclear reactor vessels, flanges for coolant storage tanks, etc.
Heavy Machinery and Hydraulics: Large hydraulic cylinders, construction machinery, mining equipment, presses, etc.
Petrochemicals and Shipbuilding: Pressure vessels, chemical processing equipment, marine machinery, etc.
Other Industries: Wind power equipment, metallurgical equipment, etc.

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.
