Stainless Steel Plate Flat Flange is a simple, cost-effective component for low-pressure industrial use. Made from 304/316L stainless steel, it features a flat sealing face and compact structure, offering reliable corrosion resistance and easy installation, favored for low-pressure piping and equipment connections.
Distinguished by its flat face design, the stainless steel plate flat flange seals tightly with gaskets for low-pressure media. Unlike slip-on flanges, it welds directly to pipes/equipment, simplifying installation and cutting costs for simple pipelines and light industry.
Our stainless steel plate flat flanges comply with ANSI/ASME B16.5, DIN 2627, EN 1092-1, available in various sizes, 150–300 pressure classes and surface finishes to meet diverse low-pressure project needs.
The 304 stainless steel plate flat flange suits general low-pressure use (water supply, HVAC, light manufacturing), while the 316L variant offers enhanced corrosion resistance for mild chemical, coastal and marine auxiliary systems.
Each stainless steel plate flat flange undergoes strict quality checks (material testing, dimensional verification, surface inspection) to ensure seamless integration and long-term reliability in low-pressure environments.
Widely used in water supply, HVAC, light manufacturing and auxiliary systems, the stainless steel plate flat flange is simple, affordable and practical—ideal for new low-pressure pipelines and maintenance.
We offer standard and custom stainless steel plate flat flanges with professional technical support and competitive pricing—your reliable choice for industrial low-pressure piping.
