Carbon Steel Raised Face Weld Neck Flanges | ASTM A105 Carbon Steel WNRF Flange
Carbon steel Weld Neck Forged Flanges have a long tapered hub and gradual transition of thickness in the region of the butt weld joining them to the suitable Carbon steel pipes. The tapered hub provides important reinforcement to the Carbon steel flange and resistance to dishing. This type of Carbon steel flanges are highly demanded for severe service conditions resulting from high pressure, sub-zero or high temperatures. These Carbon steel forged flanges are mainly used on heat coupling of pipes when there is possibility of expansion of the section while bending stress on the coupling.
