Product Description
Stainless steel slip-on flanges with hubs are integral components in process piping systems, engineered to facilitate straightforward installation while maintaining mechanical integrity and leak-tight performance. These flanges incorporate a protruding hub, which enhances structural support and promotes smoother fluid transition by minimizing turbulence at the joint.
Fabricated from corrosion-resistant stainless steel grades—such as ASTM A182 F304/L, F316/L, or duplex alloys—these flanges exhibit excellent resistance to aggressive chemical environments, elevated temperatures, and internal pressures. The slip-on configuration simplifies axial alignment during assembly and requires fillet welds on both the inner and outer diameter for secure attachment to the mating pipe, thereby ensuring long-term reliability under dynamic operating conditions.
Widely employed in industries such as chemical processing, petrochemical refining, pharmaceutical manufacturing, and food-grade systems, stainless steel slip-on hub flanges offer a cost-effective and durable solution for low to moderate pressure applications where corrosion resistance and hygienic standards are critical.
