NW Long Weld Neck Flanges
The Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. The welding neck flange is the best designed butt-welded flange of those currently available because of its inherent structural value. It is expensive because of the design. Key Features: This is the most common type of high pressure pipe flange. They are distinguished from other types of pipe flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the weld neck flange proper in terms of strength and resistance to dishing. Uses of weld neck flanges: The weld neck flange is very resistant to dishing and has a very sturdy connection because it has the pipe along with the tapered hub. The flanges are ideal for extreme fluctuations of temperature. The...
