What is ANSI B16.5 carbon steel wnrf flange ?


Weld Neck Flanges means a circular fitting with a ring on the circumference. These are machined from a forging and these are butt welded to a pipe. This is used in the industries where high pressure is required. Weld neck flanges manufacturers are India can be found in bulk, but the one which is leading and trust-worthy one is regal sales corporation. We use “A” grade quality material and thus the product is manufactured in a perfect way. Weld neck flanges dimensions consists of outer and inner diameter of the body, bolt circle and bolt hole diameter, length of the hub and many other factors are involved.
