About Weld Neck Flange
A weld neck flange is a type of flange characterized by a long, tapered hub that is welded to a pipe. This design ensures a smooth transition of stress between the flange and the pipe, providing strength and durability in high-pressure and high-temperature environments.
-
Tapered Hub: The weld neck flange has a long, tapered hub that provides an even distribution of stress during operation, which helps to prevent cracking and deformation under high pressures.
-
Butt Weld Connection: This type of flange is welded to the pipe by butt welding, where the pipe is inserted into the flange's hub and welded from both the inside and outside. This creates a strong, leak-proof connection between the flange and the pipe.
-
Raised Face or Ring Type Joint: Weld neck flanges typically have a raised face or a ring type joint (RTJ) facing to mate with a corresponding gasket or sealing surface on the opposing flange. This ensures a tight seal when the flanges are bolted together.
About Long Weld Neck Flange
A long weld neck flange (LWN flange) is a type of weld neck flange that features an elongated neck or hub compared to standard weld neck flanges.
-
Extended Neck: The defining feature of a long weld neck flange is its longer neck or hub. This extended length provides several benefits:
-
Design and Construction: Long weld neck flanges are typically manufactured from materials such as carbon steel, stainless steel, alloy steel, and other specialized alloys to meet specific requirements for corrosion resistance, temperature resistance, and mechanical properties.
