Weld Neck Flanges Manufacturers in India

MSI Fittingsis a specialised manufacturer of high quality ASME/ANSI/DIN standard weld neck flanges in India. We offer immediate delivery programs for standard sizes of carbon steel weld neck flanges and stainless steel weld neck flanges. Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to the pipe itself. This also reduces high-stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are generally used in high-pressure applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe.

Long Weld Neck Flanges are very easy to recognize at the long tapered hub, which goes gradually over to the wall thickness from a pipe or fitting. The long tapered centre provides an essential reinforcement for usage in several applications that involve high pressure, sub-zero, or elevated temperatures. A smoother transition from these flange widths to the caused pipes by the taper is a considerable benefit, under conditions of repeated bending, caused by line expansion or other forces. Long Weld Neck Flanges are bored to match the inside diameter of the mating pipe or fitting, so there will be no restriction of product flow into the pipe. Long Weld Neck Flange prevents turbulence at the joint and reduces erosion. The reason these flanges are in demand because they provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection.
