SS / Duplex and Super Duplex Slip-on Flange
Stainless steel (SS) slip-on flanges offer basic corrosion resistance and are a cost-effective option for less demanding environments. Duplex slip-on flanges provide a superior level of corrosion resistance and enhanced strength compared to standard stainless steel. This makes them ideal for applications in industries like chemical processing, oil and gas, and marine environments where greater durability is required
Super Duplex slip-on flanges offer the ultimate in corrosion resistance, especially in environments with high chloride concentrations. Their exceptional strength and ability to withstand harsher conditions make them suitable for the most demanding applications. EBY Fasteners ensures that their SS, Duplex, and Super Duplex slip-on flanges meet industry standards and provide reliable performance in a variety of settings

- UNS S32750 : Known for extreme corrosion resistance in high-chloride settings like seawater, and superior strength. Perfect for demanding uses in oil and gas, chemical processing, and desalination.
- UNS S32760 : Offers the same corrosion resistance as S32750, but even greater strength. Ideal for extreme stress applications like subsea equipment or facing harsh chemicals.
- UNS S32950 : A less common designation, but indicates a super duplex with exceptionally high alloy content for maximum corrosion resistance and strength in the most severe environments.
- F51 : Offers greater strength and corrosion resistance than standard stainless steel. Common in moderately corrosive settings like pipelines and valves within chemical plants or marine environments.
- F53 : Identical to UNS S32750, this grade excels in harsh conditions due to its corrosion resistance and high strength.
- F55 : Similar to UNS S32760, it delivers the ultimate in strength and corrosion resistance. Used in critical applications where failure isn't an option, like subsea components or within aggressive chemical processing
- Standards : To ensure compatibility and safety, slip-on flanges follow standards like ASME B16.5 or similar international ones. These standards dictate everything from size and shape to the materials they can be made from.
- The 'Slip-on' Advantage : This type of flange is designed to slip easily over the pipe you're connecting it to. Afterward, it's welded in place, making installation relatively straightforward.
- Size Matters : Nominal Pipe Size (NPS) tells you what size pipe the flange fits. Think of it like shoe sizes – you need the right match for a perfect connection!
- Pressure Handling : A flange's pressure rating (like Class 150, 300, etc.) tells you the maximum pressure it can handle safely. Picking the right rating is crucial, especially in demanding settings.
- Face Types : Raised Face (RF) - Think of it like a tiny bump for a tighter gasket seal, Flat Face (FF) - Simple and flat, just like it sounds, Ring Type Joint (RTJ) - Specially grooved for a high-pressure metal gasket
- Material : The flanges are made from robust materials like Stainless Steel, Duplex, and Super Duplex. These materials offer excellent corrosion resistance, durability, and strength.
- Design : The design of these flanges allows for easy installation and a seamless fit with existing piping systems. The outer diameter of the pipe is slightly smaller than the diameter of the slip-on flanges, which allows the flange to slide over the pipe.
- Standards : The flanges are manufactured in accordance with various standards like ASME/ANSI B16.5, EN, JIS, DIN, and other equivalent standards. This ensures their compatibility with different piping systems around the world.
- Pressure-Temperature Ratings : The flanges come in different pressure-temperature ratings classes - 150#, 300#, 400#, 600#, 900#, 1500#, and 2500#. The higher the flange ratings, the heavier the flange, and it can withstand higher pressure and temperatures.
- Applications : Due to their strength and corrosion resistance, these flanges are suitable for demanding applications, such as in the oil and gas industry.
- Quality Assurance : EBY Fasteners ensures that their flanges meet the highest standards of quality and durability. This gives users confidence in the reliability and longevity of their products
