Flange Types

Weld Neck Flange (WN)

High-neck flange, butt-welded. Highest strength and rigidity, suitable for high-temperature and high-pressure applications.

Pressure VesselsHigh-temp/High-pressure PipelinesOil & GasAerospace Hydraulic Lines

A105F316LAlloy 625C-2762205 DuplexGH4169 Ring Forged

Slip-on Flange (PL/SO)

Pipe inserted into flange inner ring and welded. Lower pressure rating, cost-effective for general applications.

Water Supply/DrainageLow-pressure Chemical LinesGeneral Piping

Blind Flange (BL)

Seals pipe ends, closes flange openings. Used for spare ports and pipeline blockage.

Same as mating flange material

Socket Weld Flange (SW)

Small bore pipes, pipe inserted into flange bore and welded. High pressure, small diameter applications.

Instrument LinesHigh-pressure Small Bore PipingHydraulic Systems
