Check Dimensions of ASTM A182 F304 Slip on Flange, Manufacturer of SS 304 WNRF Flange

Stainless steel is classified from 200-600 grades. The Stainless Steel 304 Flanges are the most used austenitic stainless steel. Having a composition of chromium and nickel makes these flanges highly resistant to corrosion, extreme temperatures along with providing them with good welding properties. These fittings are commonly seen in the mining, water filtration, food industry, chemical industries, and some other related industries. We are proudly the leading producer of Stainless Steel 304 Flanges in the country over the past decade. Our aim is to create the best products at reasonable rates for all.

Contact us today to get ASME SA182 Grade F304 Threaded Flanges at discounted rate, Largest supplier of small-quantity ASME B16.5 UNS S30400 Blind Flanges

The ASTM A182 F304 Slip-on Flange is the most commonly used flanges that are glided over the ends of the pipe and then welded together at one or more ends of pipe fittings. These flanges are also available as reducer flanges. SS 304 WNRF Flange is a weld neck flange having a raised face. The welded neck provides extra grip in holding the pipes together, while the raised place helps in the attachment. The WNR 1.4301 Flanges are another type of raised face flange, which can be customized into different sizes and shapes.

The ASME SA182 Grade F304 Threaded Flanges are made up of cast gray, malleable iron, cast brass, or forged alloy and carbon steel. These flanges come in different face types and are available in pressure ratings of 2000-6000. The ASME B16.5 UNS S30400 Blind Flanges are used to seal high-pressure vessel nozzles, which are not under use. Nozzles are mostly blanked off with these flanges for testing in pressure plants. All our products are manufactured, using the best raw materials and the latest technology. If you want to know, more about them contact us for more details.
