A flange is a pipe grade that connects pipes, tubes, pumps, valves, and other equipment in the piping industry. The Welding Neck Flange is recognized by a long protruding or tapered hub. These flanges work well in high-pressure conditions and are useful for repeated bending conditions. The flanges are designed in raised and flat face specifications. A Raised Face Weld Neck Flange is the most common flange type in the oil and gas industry. These flanges have a raised face that is above the bolting circle and can be fastened using different gasket designs. The Flat Face Weld Neck Flange has a gasket surface at the same plane as the bolting circle. This ensures that the gasket will make entire contact with the surface. A Reducing Weld Neck Flange is a versatile grade that joins piping equipment of dissimilar sizes and shapes. The flanges are available in eccentric and concentric styles. Our institution is a Weld Neck Flange Manufacturer In India that makes use of the best raw materials and uses best-of-the-line technology to produce the best products that are available at reasonable prices.
The ANSI B16.5 Duplex Steel Weld Neck Pipe Flanges are manufactured with a dual microstructure of austenitic and ferritic configuration. These flanges have exceptional strength and work well across harsh environments. A Stainless Steel Weld Neck Flange is a sought-after grade that has excellent corrosion resistance properties and works well in high pressure and temperature applications. The Carbon Steel WNRF Flange has a higher content of carbon and is very sustainable. These flanges have moderate strength and have enhanced durability. ASTM A105 WNFF Flange covers seamless forged carbon grades that are well-suited in high temperature and ambient pressure systems.
