Industrial Flanges
Weld neck, slip-on, blind, socket weld, lap joint, and threaded flanges across all pressure classes and international standards.
Overview
Forged flanges in carbon, stainless, alloy, and nickel materials, supplied from Class 150 to Class 2500 and PN6 to PN250. Available with Raised Face (RF), Flat Face (FF), and Ring-Type Joint (RTJ) facings to match your gasket and pressure-temperature rating.
Types & Configurations
Weld Neck (WNRF)
Tapered hub welded to pipe for high-pressure, high-temperature and cyclic service.
Slip-On (SORF)
Slides over pipe and is fillet-welded — economical for low-pressure service.
Blind (BL)
Closes the end of a piping run or vessel nozzle; handles full system pressure.
Socket Weld / Lap Joint / Threaded
Small-bore, stub-end, and threaded options for specialised connections.
