Slip-on flanges are renowned for being simple to install and using inexpensive materials. If Type B or Type C ends are being handled, one of the additional benefits of these flanges is that they can also be used as lap-joint flanges.
There are numerous diameters and low-pressure model options available. This flange requires double welding since it lacks a neck to rest on the pipe, in contrast to welding neck flanges.
How do Slip-on Flanges Work?
Before welding, Slip On Flanges must be slid into the pipe. In this instance, the inside and exterior of the joint are both double-welded, giving them the resilience they need to prevent leaks. They are rated to have a pressure resistance that is around 2/3 that of a welding neck flange. These products are simple to install and weld onto various pipes, making them ideal for low-pressure applications. Additionally, welding lowers the cost of manufacturing.
Slip-on flanges can be fitted on lines with only a small amount of longitudinal space. They are also simpler to align and do not require a precise cut in the pipe.
Applications of slip-on flanges
Slip-on flanges are primarily utilized with low-pressure or leakage-risk fluids. These flanges are widely used today in process lines for substances like steam, oil, gas, condensates, etc., as well as cooling water lines, firefighting water lines, and low-pressure compressed air lines. However, it should be kept in mind that the working circumstances are not difficult and the material needs to be spread under minimal pressure.
Pros of Slip-on Flanges
- Low price
- Ease of installation and assembly
- They take up the smallest amount of longitudinal room for a flange.
- They are available in a variety of diameters.
Cons of Slip-on Flanges
- Applications involving high pressure should not be used
- The use of dangerous gases or fluids is not advised.
