Weld Neck Flanges is used where high pressure is required. These pipe flanges attach by welding the pipe to the neck of the flange. It helps in reducing the stress concentration from the bottom of the center. JF Engineering offers the best weld neck flanges with a hub in varieties of specifications, grades, materials and sizes. These type of flanges have a long tempered hub and used in applications where high pressure is a factor. When ordering a weld neck flange, it is essential to identify the schedule pipe is being used for. This is because the inside diameter of the flange will match the inside diameter of your pipe. The buttweld joint this flange has with the pipe along with the tapered hub, makes this flange very resistant to dishing and a very sturdy connection. Weld Neck Flange is an ideal product used in extreme fluctuations of temperature and environments where there may be a lot of bending and handling of the flanges.
Weldneck flange bore is machined to coordinate the ID of the pipe or fitting. This makes a smooth move to and from the weld neck flange and prevents turbulence. It helps in distributing the stress through tapered neck.
