Weld Neck Raised Face (WNRF)


ANSI B16.5 Class 150, 300, 600, 900 Weld Neck Flanges Manufacturers, ASME B16.47 Series A and B Weld Neck Raised Face (WNRF) Flange Suppliers in Mumbai, India.

Kencotube is well known manufacturing house of Weld neck raised face flanges (WNRF), which is one of the most commonly used flange in the piping industry. Stainless Steel Weld neck raised face flanges are easy to recognize with their long tapered hub that is matched to the wall thickness (bore) of the pipe. These Carbon Steel Weld neck raised face flanges are attached by welding the pipe to the neck of the flange, where this transfers stress from the flange to the pipe instead. Alloy Steel Weld neck raised face flanges also reduce the stress concentration from the base of the hub, where bore is machined to match the ID of the pipe or fitting. Alloy 20 Weld neck raised face flanges creates a smooth transition to and from the weld neck flange and prevents turbulence at the welding neck.
