Stainless Steel Weld Neck Flanges Manufacturer In India

Weld Neck Flange

Superior quality Manufacturer and supplier of ASME B16.5 Weld Neck Pipe Flanges and Carbon Steel WNRF Flange

A flange is a device that has a protruded lip or lip that allows it to connect efficiently to different piping equipment. The Weld Neck Flange is recognized by a long protruding hub or face. These flanges are joined to the pipe using a versatile butt-weld. This Wnrf Flange has superior strength and helps in relocating stress and decreasing the higher concentration of pressure. This makes the WNRF grade a good choice in repeated bending applications caused due to the line of expansion and other variable forces. The Welding Neck Flange assures a smooth flow of liquid passing through the pipe. These flanges can readily handle high pressure and temperature fluctuations. A Stainless Steel Weld Neck Flange has excellent corrosion resistant properties and is extremely reliable. These flanges are easier to install and align with the piping equipment as they have a natural form of connection. The Carbon Steel Weld Neck Flange has a higher content of carbon this gives them higher durability and excellent sustainability. A Carbon Steel Weld Neck Flange has good hardness and outstanding mechanical properties. These flanges have good strength and have enhanced shock resistance properties.

Exporter of Super Duplex Raised Face Weld Neck Flange, We offer 304/ 316 Stainless Steel Wnrf Flange in various face such as Raised, RTJ according to EN 1092-1

A Long Weld Neck Flange is similar to a weld neck flange; however, they have an extended neck that acts as a boring extension in comparison to the latter. The Long Weld Neck Flange works well across higher pressure and temperature setups. These flanges have good strength and easily balance different conditions. An LWNRF grade is easy to work with and is common in oil and gas, petrochemical, chemical processing, nuclear systems, etc. We are a Weld Neck Flange manufacturer in India who have a wide stock of inventory allowing us to supply flanges of different specifications to our customers.
