Slip-On

Description

A slip-on flange is a type of flange that is slipped over the end of a pipe and then welded in place. It has a bore slightly larger than the outer diameter of the pipe it is intended to be used with, allowing the pipe to be inserted into the flange. Slip-on flanges are then typically welded both inside and outside to provide strength and prevent leakage.

Here are some key characteristics and features of slip-on flanges:

1. Ease of Installation: Slip-on flanges are relatively easy to install because they can be easily slipped onto the pipe before welding. This makes them a popular choice for applications where frequent disassembly and reassembly may be necessary.
2. Cost-Effective: Slip-on flanges are generally more cost-effective compared to welding neck flanges because they require less material and are simpler to manufacture.
3. Limited Pressure and Temperature Ratings: Slip-on flanges are suitable for low to moderate pressure and temperature applications. They may not be recommended for high-pressure or high-temperature systems due to the inherent design limitations.
4. Raised Face or Flat Face: Slip-on flanges are available with either a raised face or a flat face. A raised face provides a sealing surface for a gasket, while a flat face requires special consideration for sealing.
5. Applications: Slip-on flanges are commonly used in systems where easy assembly and disassembly are required, such as in water supply, plumbing, and low-pressure piping systems.

It’s important to note that slip-on flanges may not be suitable for all applications, especially those involving high pressure or temperature, where welding neck flanges or other types may be more appropriate. The choice of flange type depends on factors such as system requirements, operating conditions, and installation preferences.
