Sanghvi Impex Industries provides an exclusive range of Weld Neck Flanges with high standard quality of materials. As the name suggest it's actually a neck piece of the flange that is welded to the closing points of the system of pipes. Weld Neck Flanges are known from other breeds by their widespread pointed centre and reasonable development of width in butt weld area, by joining them by means of the pipe. These types of flanges are having a wide-ranging tapered hub and are often used for high pressure applications.

Meanwhile, the all-embracing pointed centre provides a momentous support of the proper flange, from the position of resistance and power to dishing. These flanges are jaded to bout the inner diameter of the mating pipe so there will be no constraint of product flow. Well, this thwarts commotion at the joint and minimizes erosion. They as well offer good stress distribution throughout the tapered hub and are radiographed for failing detection without any difficulty.
