Contact Supplierstainless steel Welding Neck Flange is designed with a hub on the backside tapering to a diameter that will match the pipe to which it will be welded. These flanges are bored to match the inside diameter of the mating pipe so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. Welding neck flanges are preferred for use in severe service applications involving high pressure, sub-zero and/or elevated temperatures.
They also provide excellent stress distribution through the tapered hub and are easily radio graphed for flaw detection.
