Manufacturer of ASTM A182 F316L Slip On Flange, View Dimension of UNS S31603 WNRF Flange

316L alloy is the lower carbon version of the 316 alloy. The Stainless Steel 316L Flanges are made up of iron, chromium, nickel, and molybdenum. This austenitic steel alloy is highly resistant to corrosion and doesn’t deform easily under elevated temperatures. Along with this, these flanges have good yield and tensile strength along with excellent formability. These flanges are seen in the food industry, petrochemical, chemical, and marine industries. We are one of the leading manufacturers of Stainless Steel 316L Flanges. We thrive to produce the best products at the most reasonable prices.

Delivering Class 150 ANSI 316L Forged Flanges everywhere, Suppliers and Stockists of 316L SS SWRF Flange

ASTM A182 F316L Slip On Flange is the most common flange which is slid onto the pipe allowing, it to be on the center of the flange. The flange is welded on the exterior diameter and the interior side of the connection. The DIN 1.4404 Socket Weld Flanges are connected; with the help of a single fillet weld. This family of high-pressured fittings is used across various industries. The UNS S31603 WNRF Flange is used for high-pressure applications. These flanges are welded to the base of the pipe, and the center bore matches the pipe, allowing smooth and steady flow. Our team members use the best raw materials using the best technology following international and national standards.

Class 150 ANSI 316L Forged Flanges is made from alloy and carbon compressed under extreme pressures this ensures the formation of strong material. This supports different structures in piping systems. The ANSI B16.5 SS 316L Blind Flange doesn’t have a boring center or hub and is used to seal the ends of pipes or nozzles. All our products can be customized into different shapes and sizes. Want to know more about our flanges contact us.
