Flanges

A flange is a forged or cast component used to connect pipes, valves, pumps, and other equipment in piping systems. Flanges allow easy assembly, inspection, maintenance, and disassembly.

Common Types

• Weld Neck Flange (WN) – Used for high-pressure and high-temperature services.
• Slip-On Flange (SO) – Slides over the pipe and is welded.
• Blind Flange (BL) – Used to close the end of a piping system.
• Socket Weld Flange (SW) – Used for small-bore, high-pressure piping.
• Threaded Flange – Connected without welding.
• Lap Joint Flange (LJ) – Used with stub ends for easy alignment.

Materials

• Carbon Steel
• Stainless Steel (304, 316)
• Alloy Steel
• Duplex Stainless Steel
• PVC / HDPE (for plastic piping)
