A Integral Flange which is also called Long weld neck flange (LWN flange), is used for high pressure situations, integral hub weld neck flanges are used and for very high pressure cases Long Welding Neck flanges are preferred. In this case, the weld are far from the ring to avoid bending stresses and weld stress being combined.
Long Weld Neck Flange is similar to Welding Neck Flange with extensive large neck/bore used to weld against other pipe or fittings.
Long Weld Neck Flange is special purpose flange. Unlike standard weld neck, it is manufactured with large neck from forging stock or can be directly machined from a forged round bar.
