Stainless Steel Slip on Flange (SO Flange) is a versatile, budget-friendly piping component for low-medium pressure industrial and marine use. Crafted from 304/316L stainless steel, this slip on flange offers excellent corrosion resistance, easy installation and reliable weldability, favored by global contractors and plant operators.
Its user-friendly design—slightly oversized inner diameter—lets the stainless steel slip on flange slide easily over pipes, simplifying alignment. Secured by two fillet welds, it forms a leak-proof seal for industrial fluids, gases and mild chemicals.
Our stainless steel slip on flanges comply with ANSI/ASME B16.5, DIN 2634 and EN 1092-1 standards, available in various sizes, 150–600 pressure classes and surface finishes to meet diverse project needs.
The 304 stainless steel slip on flange suits general use (water treatment, HVAC, food processing), while the 316L variant resists chloride corrosion for marine, coastal and chemical processing environments.
Each stainless steel slip on flange undergoes strict quality checks (raw material testing, dimensional verification, weldability and surface inspections) to ensure seamless piping integration and reliable performance.
Widely used in water treatment, chemical, marine, HVAC and food industries, the stainless steel slip on flange balances affordability, easy installation and durability—ideal for new builds and maintenance.
We offer standard and custom stainless steel slip on flanges with professional technical support and competitive pricing—your reliable choice for industrial and marine piping needs.
