Shanxi Jianing Forging produces a full range of flanges, including plate-type flat welding, neck butt welding, stainless steel, carbon steel, wind turbine tower tubes, pressure vessel flanges, blind plates, figure-8 blind plates, and threaded special-shaped flanges, all customizable with multiple sealing surface types, and a full set of production qualifications for stable supply.
Pressure vessel flanges often leak or require frequent maintenance due to poor sealing or dimensional deviations during use. Jianing's forged container flanges use high-precision machining and high-quality forgings to address leakage pain points at the source, providing reliable connection solutions for industries such as petrochemicals and energy.

Jianing forged container flanges are connecting components specifically designed for pressure vessels, covering various types such as flat welding, butt welding, and concave-convex surfaces. The product is forged from high-quality carbon steel, stainless steel, or alloy steel, strictly adhering to national standards such as NB/T 47023, helping the flange strength, sealing, and durability meet working requirements.
High-precision machining: CNC lathe precision machining, sealing surface roughness Ra≤3.2μm, dimensional tolerances meeting standards.
Strong sealing structure: Multiple sealing surface types (RF, FF, MFM, TG, etc.) to accommodate different media and pressure levels.
High pressure resistance and corrosion resistance: Undergoing strict heat treatment and non-destructive testing, suitable for environments with high temperature, high pressure, and corrosive media.
Full traceability: Each flange comes with a material report and certificate of conformity to help maintain consistent quality.
Container flanges are customized products, with prices calculated comprehensively based on material, specifications, quantity, and technical requirements. Please provide specific parameters or drawings, and we will provide you with a one-on-one quotation service.
If there are non-human quality issues during the warranty period, returns or exchanges are free.
We provide technical selection consultation and installation guidance.
Standard specifications ship within 48 hours; expedited orders can be negotiated.
