Manufacturers, Suppliers, Traders, Exporters and Stockists of Stainless Steel Long Welding Neck Flange
ARK Stainless is a leading manufacturers, supplier, trader, stockist and exporter of high quality Long Welding Neck Flange in India. Long Weld Neck Flanges have a hub that extends from the flange's flat surface, which helps in accommodating the pipe more easily. Alloy Steel Long Weld Neck Flange fall under the group of speciality flanges, providing reinforcement in services at higher temperatures in the oil industry. A Carbon Steel Long Welding Neck Flanges is preferable in the petroleum and chemical industry as they operate under fluctuating temperature ranges.
Long Welding Neck Flanges is normally referred to as the high hub flange. It is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the base of the flange.
A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant. A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.
Long Welding Neck (abbreviated LWN) flanges are similar to a standard Welding Neck flange, but the "Neck" is considerably longer. This type is often used as a nozzle for a barrel or column. In addition, there are the type LWN Heavy Barrel (HB) and the Equal LWN Barrel (E); they have a different shape and a thicker "Wall".
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 width 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.
