ASME B16.5 Weld Neck Flange
Manufacturer of Stainless Steel Flat Face Weld Neck Flange, View Dimensions Carbon Steel WNRF Flanges
Weld neck flange is the most used flange in the piping industry. These flanges are easily recognizable with their long tapered hub, which matches with the bore of the pipe. The Stainless Steel Flat Face Weld Neck Flange is used in applications that require high pressures and in situations of low and high-pressure extremes. This stainless flange also help in low cycle fatigue which is caused by extension of a line and other variable forces. We are proud to be the leading producers of Weld Neck Flange manufacturers in India. Our main goal has always been to produce the best products, which are available to all at reasonable rates.

Stainless Steel Flat Face Weld Neck Flange
Carbon Steel WNRF Flanges
We Have Been Supplyed Mss-sp-44 Weld Neck Flange, Long Weld Neck Flange 600# Stockists in Kolkata
The Carbon Steel WNRF Flanges have a higher concentration of carbon. This carbon is what gives it a low melting point. The concentration of carbon gives the flange its strength and ductility. The Mss-sp-44 Weld Neck Flange is made up of forged steel or a steel plate. This flange covers ratings, pressure and temperature, tolerances required for steel pipes. We manufacture all our products under strict supervision from our experienced and knowledgeable team members. Our team members use the best raw materials using the best technology following international and national standards.
The ASME B16.5 Long Weld Neck Flange 600# has a neck, which acts as a boring extension. These flanges have high tensile strength and are mostly used in oil, gas, or petrochemical industries. Our experienced staff also produce the Pn16 Weld Neck Flange which is ideal for creating piping system access points. If you want customized flanges or want to know more about our flanges, contact us.
