Large heavy-duty forgings
Flange type
Scope of Application
Welding flanges are not easily deformed, have good sealing, and are widely used. They are suitable for pipelines with significant pressure or temperature fluctuations, as well as pipelines with high, high, and low temperatures. The advantage is that they are relatively inexpensive, with a nominal pressure not exceeding 2.5 MPa; It is also used on pipelines that transport expensive, flammable, and explosive media, with a nominal pressure of around PN16MPa.

production process
Forging, casting, and medium plate manufacturing
Slip-on Flange
The connection form is single-sided welding and double-sided nut connection.
Product features: Beautiful appearance, smooth and even surface, acid and alkali resistance, anti-corrosion resistance, strong texture performance.
The production process involves cutting materials in a sub oxygen furnace, forging them as a whole, or forging and cutting them into finished products.
Processing methods include high-precision CNC lathe turning and CNC rocker drilling.
We also provide forging blanks and CNC precision machining services for our clients, covering industries such as energy, petrochemicals, steel, engineering machinery, plastics, prevention and control, hydraulics, healthcare, and food. Please feel free to send us drawings for inquiries.

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.
