Large Size Of Forged Valve

Large Size Forged Valve is available in integral forging, split forging, or forged-welded construction, suitable for high-pressure, high-temperature, and harsh media pipelines.

Forged Structure: Utilizing forged or welded construction, combined with heat treatment and non-destructive testing to control material quality, suitable for high-pressure, high-temperature, and pressure-fluctuating pipelines.

CNC Machining: Valve body, stem, and seat are precision machined, controlling key dimensions and sealing surface fit, and verifying sealing performance through pressure testing.

Full-Process Inspection: Covering materials, dimensions, machining, assembly, and pressure testing, PMI, UT, RT, MT, PT, and third-party inspections can be provided according to project requirements.

Multiple Valve Body Structures: Integral Forged, Split Forged, or Forged-Welded structures are available based on valve type, diameter, and pressure rating.

Sealing Structure: Valve seat, disc, ball, stem, and packing are configured according to valve type, with sealing performance controlled through machining, assembly, and pressure testing.

Pipe Connections: Supports RF, RTJ, and Butt Weld connection types to meet the installation requirements of different piping systems.

Forging and Heat Treatment: Perform appropriate forging and heat treatment processes according to the material, controlling the material microstructure and mechanical properties.

CNC Precision Machining: Machin the valve body, valve stem, valve seat, and connecting ends, focusing on controlling dimensions, coaxiality, and sealing surface quality.

Assembly and Testing: Complete cleaning, assembly, opening and closing checks, pressure testing, and factory inspection.

Raw Material Inspection: Perform material certificate, chemical composition, mechanical properties, hardness, PMI, and UT checks according to project requirements.

Dimensional Inspection: Inspect the valve body, flanges, face-to-face, and critical machining dimensions.

Pressure Testing: Perform Shell Test, Seat Test, and functional tests according to applicable standards.

NDT Testing: Provide non-destructive testing (NDT) such as UT, RT, MT, and PT, and related reports.

Dimensions and Pressure: Support customization of DN/NPS, face-to-face, and pressure rating.
