Every flange type required for oil & gas, petrochemical, power and water desalination projects.
Weld Neck Flanges
Tapered hub design for high-pressure, high-stress piping systems requiring full weld penetration.
Slip-On Flanges

Blind Flanges
Used to seal the end of a piping system, valve, or pressure vessel opening.
Threaded & Socket Weld
For smaller-bore piping where welding is impractical or where a mechanical joint is preferred.
