Manufacturer of ASTM A182 F304l Blind Flange, View Dimensions of UNS S30403 Slip on Flange

Grade 304L is made up of carbon, nickel, chromium, phosphorous, manganese, and sulfur. The Stainless Steel 304L Flanges is a lower carbon version of the 304 alloys. This alloy is magnetic when it is cold-worked but, when annealed, it becomes non-magnetic. The low carbon reduces the risk of corrosion and harmful carbide precipitation. Along with this, they have good welding and forming capabilities. These flanges are seen predominantly in the food industry along with construction, chemical, and mining industries. We are one of the top Stainless Steel 304L Flanges who focus on creating high-quality products at the most reasonable prices.

ASME SA182 SS 304L Blind Flanges are produced from a plate, cast, or forged materials. The dimensions of this flange are considered perfect to be used by industrialists, manufacturers, suppliers, and architects. While the ASTM A182 F304l Blind Flange is used to seal high-pressure vessel nozzles, which are not in use or for testing in industries. The sizes of these flanges range from ½ to 48 inches. The SS 304L Threaded Flanges are commonly called companion flanges, which help in reducing connections. Our renowned workers make use of the best raw materials and the latest technology while producing the best products.

UNS S30403 Slip on Flange is low cost and can be easily installed by sliding the flange onto the edge of the pipe. These flanges can be connected directly by welding them onto the pipe. The SA182 F304L Weld Neck Flange is used to reinforce applications requiring high pressures and extreme temperatures and is the most common flange in the piping systems. All our flanges can be customized into different shapes and dimensions as per requirements. Want to know more about our products contact us.
