What are Weld Neck Flange?
A weld neck flange is known for its long-tapered hub that gives it solid mechanical support. Welding neck flanges are reliable and come in various sizes, face types, and classes. Because of the sturdy hub and secure weld, this flange type is ideal for high-temperature and pressure environments. The smooth flow and minimal turbulence of a welding neck flange are attributed to its low-pressure drop. We stand for on-time deliveries as we are the top Weld Neck Flange Supplier in UAE.
Two types of weld neck flanges are standard and extended. Standard ones are for butt weld fittings, while long ones are for vessel nozzles and equipment. They are made to fit the pipe's inside diameter or fitting. It can withstand high pressure and temperatures, is resistant to oxidation, and shows excellent resistance to corrosion in different environments.
