Application and Advantage of Weld neck flange

Weld neck flange are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow.This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection.



Application of weld neck flange

Weld neck flange have a long tapered hub and are often used for high pressure applications.When ordering a weld neck flange, it is important to specify 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.These flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.



Advantages of weld neck flange

Such flanges are suitable for use in hostile environments that have extremes of temperature,pressure or other sources of stress.The resilience of this type of flange is achieved by sharing the environmental stress with the pipe with which it is welded.This type of flange has been used successfully at pressures up to 5,000 psi.

The weld neck flange derives its name from the neck portion of the flange that is welded to the end of a piping system.It is designed to transfer stress to the pipe,thereby reducing high stress concentrations at the base of the flange.Weldneck flanges are costlier due to their design and engineering,and increased material.
