James Duva supplies weld neck flanges that are durable, reliable and withstand stress for high-pressure applications.
Weld Neck Flanges come with a tapered hub for additional reinforcement and are used for severe service conditions including extremely high temperatures, extremely low temperatures, or high pressure. These flanges are attached by welding the pipe to the flange neck in order to transfer stress from the flange to the pipe. These flanges may be produced in a variety of different materials.
Welded neck pipe flanges are most often created with a raised face, flat face, or RTJ facing. When a raised face is necessary for weld neck pipe flanges, the standard height is 1/16″ for weld neck pipe flanges under 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4″.
They are also often referred to as Butt Weld Flanges. When joining these to a pipe, the “neck” is butted up to the pipe and welded, similar to welding two pieces of pipe together.
Welded neck flanges are also manufactured to withstand the most hostile applications with extreme temperature and pressure. This is achieved by sharing stress with the pipe that it is welded to. This flange has been proved to be successful up to 5,000 psi.
From high pressure and during high and low-pressure extremes, the welded neck flanges proves to provide reliable reinforcements for applications. It is also proven to help in low cycle fatigue that can be caused by line expansion of other forces.
