Slip-on flanges are a popular type of Pipe flanges. These are type of flanges that slide over the end of piping and then welded in place. These flanges are ideal for lower pressure applications. These are easily fitted and welded into different pipes. Welding reduces fabrication costs of these pipes. These are available in wide variety of sizes and applications.
For many users, slip on flanges continue to be preferred to welding neck flanges because of the following reasons:
Some important features are as follows:
One size fits all pipe schedules.
Fabricators can more easily cut pipe to length for slip-on flanges.
The smaller thickness of this flange allows for easier alignment of bolting holes.
They are generally not preferred for high pressure temperature environments.
Low cost installation
Less time needed to spent on ensuring the accuracy of the cut Pipe
They are somewhat easier to align
The slip-on flanges have low hub because the pipe slips into the flange before welding
The flange is welded both inside and outside to provide sufficient strength
They prevent leakage
