ASTM A182 Gr F316 Weld Neck Flange Manufacturer, View Weight Chart of UNS S31600 RTJ Flange

Alloy 316 is austenitic steel made up of chromium, nickel, and molybdenum. The 4% molybdenum in this Stainless Steel 316 Flanges gives it good mechanical and physical properties. It also makes these flanges highly corrosion resistant against acids such as sulphuric, hydrochloric, acetic, formic, and tartaric acids. These flanges retain their structure at elevated temperatures. They are widely used in several applications like piping, valves, exhaust manifolds, petrochemical, food industry, pulp, and paper industry, etc. We are one of the top manufacturers of Stainless Steel 316 Flanges. The goal of our institution is to produce the best products at the most economical rates.

Biggest ASME B16.5 SS 316 Pipe Flange Supplier, Refer Dimensions of Stainless Steel 316 Slip On Flanges

UNS S31600 RTJ Flange is a high integrity-sealing flange, which is used when mating flanges require a metal-to-metal seal. This flange can withstand pressures and temperatures above 700-800 degrees. To prevent chloride ion corrosion, the ASTM A182 Gr F316 Weld Neck Flange is preferred. These flanges are used to seal high-pressure vessel nozzles, which are not in use or for testing in industries. Our ASME B16.5 SS 316 Pipe Flange can be customized into different sizes and dimensions as per your requirements.

In the SA 182 F316 Socket weld Flanges, there is a recessed area in the bore this area serves as a guide to show how deep the pipe can be inserted in the flange. These flanges have 50% more fatigue strength as compared to slip-on flanges. DIN 1.4401 Forged Flanges are used to combine 2 machinery parts. These flanges act as an extension to provide support to a structure. Our renowned workers make use of the best raw materials and the latest technology while producing the best products.
