Slip-on flanges are one of the most commonly used pipe flanges in various industries due to their easy installation, cost-effectiveness, and strong structural support. These flanges slide over the pipe and are welded in place, making them ideal for applications where quick and efficient connections are required. Available in stainless steel, carbon steel, alloy steel, and duplex steel, slip-on flanges are widely used in piping systems that transport fluids and gases under moderate pressure.
At AB Steel, we offer high-quality slip-on flanges in various grades, including SS 304, SS 316, ASTM A105, ASTM A182 F304, F316, and duplex steel 2205.
Uses of Slip-On Flanges
1. Oil & Gas Industry
Slip-on flanges are widely used in oil refineries, natural gas plants, and offshore platforms where secure and leak-proof piping connections are essential. Carbon steel slip-on flanges (ASTM A105) are commonly used in these high-pressure environments due to their durability and strength.
2. Chemical and Petrochemical Industry
In chemical processing plants, stainless steel slip-on flanges (ASTM A182 F304, F316) are preferred due to their superior resistance to corrosion, acids, and high temperatures. These flanges are essential for chemical transport pipelines, distillation columns, and reactor systems.
3. Water Treatment and Plumbing Systems
Slip-on flanges are commonly used in municipal water treatment plants, plumbing networks, and wastewater management systems. Duplex steel slip-on flanges (2205) are preferred for their high strength and corrosion resistance, making them suitable for harsh water environments and desalination plants.
4. Power Generation Plants
In thermal, nuclear, and hydroelectric power plants, slip-on flanges play a vital role in steam pipelines, cooling water systems, and high-temperature fluid transport. Alloy steel slip-on flanges (ASTM A182 F11, F22) are commonly used due to their high-temperature resistance and excellent mechanical properties.
5. Food and Beverage Industry
Slip-on flanges made from stainless steel 304 and 316 are extensively used in the food and beverage industry, as they ensure hygienic and contamination-free fluid transport. These flanges are used in breweries, dairy processing plants, and beverage production units where cleanliness and corrosion resistance are critical.
6. Marine and Offshore Applications
For marine piping systems, offshore drilling rigs, and shipbuilding, stainless steel 316 and duplex 2205 slip-on flanges are ideal choices due to their superior resistance to saltwater corrosion and harsh marine conditions.
Conclusion
Slip-on flanges offer versatility, durability, and ease of installation, making them essential for a wide range of industries. Whether used in oil & gas, chemical processing, power plants, or marine applications, selecting the right material and grade ensures optimum performance and longevity.
At AB Steel, we supply premium-quality slip-on flanges in stainless steel, carbon steel, alloy steel, and duplex steel, available in grades such as SS 304, SS 316, ASTM A105, A182 F304, F316, and Duplex 2205.
