The stainless steel plate flat flange is a reliable, cost-efficient solution tailored for low-pressure industrial applications. Fabricated from premium 304/316L stainless steel, this plate flat flange boasts a flat face design and compact structure, delivering strong corrosion resistance and hassle-free installation for low-pressure piping and equipment interfaces.
Its flat face design ensures tight sealing with gaskets, perfectly适配 low-pressure media transfer. Unlike slip-on flanges, the stainless steel plate flat flange is directly welded to pipes or equipment, streamlining installation processes and reducing overall project costs for simple pipelines and light industrial scenarios.
Our stainless steel plate flat flanges adhere to strict international standards (ANSI/ASME B16.5, DIN 2627, EN 1092-1), available in various sizes, 150–300 pressure classes and surface finishes to accommodate diverse low-pressure project requirements.
The 304 stainless steel plate flat flange is ideal for general low-pressure applications (municipal water, HVAC, light manufacturing), while the 316L stainless steel plate flat flange offers enhanced corrosion resistance for mild chemical processing, coastal pipelines and marine auxiliary systems.
Every stainless steel plate flat flange undergoes rigorous quality inspections, including material composition testing, dimensional accuracy checks and surface defect screening, ensuring seamless integration and long-term reliability in low-pressure operating environments.
Widely applied in municipal water supply, HVAC systems, light manufacturing and industrial auxiliary pipelines, the stainless steel plate flat flange is valued for its reliability, affordability and practicality—perfect for new low-pressure projects and maintenance upgrades.
We provide both standard and custom stainless steel plate flat flanges, supported by professional technical guidance and competitive pricing, serving as your trusted partner for industrial low-pressure piping solutions.
