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.
