Dimensions of Long Weld Neck Flange:The long weld neck flange should be butt welded with the pipes,it means the neck dimensions is same with the matching pipe,same diameter and wall thickness,commonly the long weld has a plain end,not a bevel end for welding.Except the neck, the LWN flange has a same dimensions with the welding neck flange.In addition,there are also the type LWN heavy barrel (HB) and the equal LWN barrel (E);they have a different shape and a thicker “Wall” which name is nozzle. Sealing Face of the Long Weld Neck Flange:The sealing face of the long weld neck flange is same with the weld neck flange,so it could be raised face(RF),flat face(FF) or ring type joint(RTJ),the long weld neck flange is suitable to be used for the high pressure application.
