Industrial Pipe Fittings

Coating: G.I/RAW/WARNISH

Available Size: 1/2" - 14"

🔎 What It Is:

A Weld Neck Raised Flange is a type of flange designed to be welded to the pipe’s neck (or pipe end) by butt welding. It features a raised face around the flange bore to improve the seal when connected to another flange with a gasket. This design provides high strength and is suitable for high-pressure and high-temperature applications.
