A slip-on flange is a type of flange that is designed to slide over the end of a pipe and then be welded in place
- Bore Size:
- The bore size of a slip-on flange is slightly larger than the outside diameter of the pipe to allow the flange to slip over the pipe.
- Welding:
- The slip-on flange is welded both inside and outside to provide strength and prevent leakage.
- Raised Face:
- Many slip-on flanges have a raised face that offers a surface for a gasket to make a seal.
- Hub:
- Slip-on flanges have a hub at the base with bolt holes for connecting to the mating flange.
- Applications:
- Commonly used in applications with low pressure and temperature conditions.
- Suitable for non-critical applications where ease of assembly and disassembly is important.
- Flange Face Options:
- Slip-on flanges are available with flat face (FF) or raised face (RF) configurations.
Advantages of a Slipon Flange
- Easy Installation:
- One of the main advantages is the ease of installation. Slip-on flanges are relatively simple to fit onto the pipe and weld in place.
- Cost-Effective:
- Generally more cost-effective compared to other types of flanges, making them suitable for budget-conscious projects.
- Smooth Flow:
- The smooth bore of the slip-on flange ensures a continuous and unobstructed flow of fluids or gases through the piping system.
- Wide Range of Applications:
- Suitable for a variety of applications, including low-pressure systems, water supply, and less critical environments.
Points to consider when using a Slipon Flange
- Limited Pressure and Temperature:
- The Slipon Flange is not suitable for high-pressure or high-temperature applications due to the weld attachment and lack of a tapered neck for reinforcement.
- Weld Integrity:
- The strength and integrity of the connection depend on the quality of the weld. Proper welding procedures must be followed to ensure a secure joint.
- Gasket Sealing:
- The raised face design allows for the use of gaskets to create a seal. Proper selection of gasket material is important for effective sealing.
- Critical Alignment:
- Proper alignment during installation is crucial to ensure a secure and leak-free connection.
Slip-on flanges are commonly used in scenarios where the ease of installation and cost-effectiveness are primary considerations. They are often chosen for applications where the pipe needs to be frequently disassembled, or where the system operates at lower pressures and temperatures. As with any type of flange, it’s important to consider the specific requirements of the application and adhere to industry standards during installation
