Manufacturers, Suppliers, Traders, Exporters and Stockists of Stainless Steel Long Welding Neck Flange
ARK Stainless is a leading manufacturer and supplier of high-quality SS Long Welding Neck Flanges in India. Our Long Weld Neck Flanges feature a hub that extends from the flange's flat surface, allowing for easier accommodation of the pipe. Alloy Steel Long Weld Neck Flanges are considered specialty flanges, providing reinforcement for high-temperature services in the oil industry. A Carbon Steel Long Welding Neck Flange is preferable in the petroleum and chemical sectors, as it operates efficiently under fluctuating temperature ranges.
Commonly referred to as high-hub flanges, Long Welding Neck Flanges are designed to transfer stress to the pipe, thereby reducing high stress concentrations at the base of the flange. These flanges consist of a circular fitting with a protruding rim around the circumference, typically machined from a forging, and are butt welded to a pipe. The rim features a series of drilled holes that allow the flange to be affixed to another flange with bolts.
Long Welding Neck (LWN) flanges are similar to standard Welding Neck flanges but have a considerably longer neck. This type is often used as a nozzle for barrels or columns, and we offer various types, including LWN Heavy Barrel (HB) and Equal LWN Barrel (E), which have different shapes and wall thicknesses.
Our Long Welding Neck Flanges are easily recognizable by their long tapered hub, which transitions gradually to the wall thickness of the pipe or fitting. This design provides essential reinforcement for applications involving high pressure, sub-zero temperatures, or elevated conditions. The smooth taper from the flange width to the pipe ensures no restriction of product flow, preventing turbulence at the joint and reducing erosion. These flanges excel in providing excellent stress distribution through the tapered hub and can be radiographed for flaw detection.
Our high-grade Long Welding Neck Flanges possess many features that make them ideal for various industrial applications, including precision metal stamping for consistent quality. They are durable, anti-corrosive, dimensionally accurate, and easy to install, requiring minimal maintenance. With these qualities, our flanges are a convenient choice for many clients. We offer a complete range of SS Long Welding Neck Flanges, including 304 Long Welding Neck Flanges, 316L Long Welding Neck Flanges, Duplex Long Welding Neck Flanges, and more, ensuring we meet the diverse needs of our valued buyers.
