Weld Neck Flange products are very simple to remember at the long tapered hub, which goes gradually over to the wall thickness from a pipe or fitting. The long-tapered  centre provides a vital reinforcement for usage in several applications that involve high pressure, sub-zero, or elevated temperatures. A smoother transition from these flange’s thicknesses to the affected pipes by the taper is a considerable benefit, under conditions of repeated bending, caused by line expansion or other forces. Weld Neck Flanges are bored to match or connect the inside diameter of the mating pipe or fitting, so there will be minimal or no restriction of product flow into the pipe. As a result, Weld Neck Flange help restricts turbulence at the joint and reduces erosion. These flange types are in demand because they provide outstanding stress distribution through the tapered hub and are readily radiographed for flaw detection.

Nextgen Steel & Alloys have a team of design engineers and manufacturers who produce various flange products with the best working features. Our quality professionals recommend using pure alloys as a raw material that is superior and gives additional strength. Thus reliable material is procured to give additional corrosion strength.
