Stainless Steel Back Up Flange

Stainless steel back-up flanges, also known as stainless steel support flanges or backup ring flanges, are primarily used in conjunction with flange bodies and gaskets. By evenly distributing the pressure generated during bolt tightening, they prevent deformation and warping of the flange sealing surface, thereby improving the sealing integrity and structural durability of the pipeline interface. Made of 304 or 316L stainless steel, they resist corrosion from acidic and alkaline media, salt spray, and high-temperature water vapor, making them suitable for harsh working conditions in chemical, marine, and water treatment industries, significantly extending their service life. Their high material stability prevents rusting and aging, reducing the need for frequent replacements and lowering maintenance costs, making them particularly suitable for industrial systems operating continuously for extended periods.

 Petrochemical Industry: Stainless steel back-up flanges are used for crude oil transportation, chemical reaction vessels, and acid/alkali pipeline interfaces, resisting high temperature, high pressure, and corrosive media corrosion to ensure leak-free system operation.

 Water Treatment and Environmental Protection Industry: Suitable for sewage treatment plants, seawater desalination equipment, and pure water transportation pipelines, resisting corrosion from chlorine-containing media and preventing secondary pollution.

 Marine Engineering: Used in ship piping and offshore platform piping systems, resisting salt spray and seawater corrosion, and adapting to turbulent and high-pressure fluctuations.

HVAC and Power Industry: Used in power plant boilers and air conditioning/HVAC pipes, withstanding high-temperature steam pressure and ensuring long-term stable sealing of joints.

 Food and Pharmaceutical Industry: Made of 304/316L material that meets hygiene standards, suitable for clean pipes in food processing and pharmaceutical production, avoiding material contamination.
