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.
Why slip on flanges are preferred to welding neck flanges?
For many users, slip on flanges continue to be preferred to welding
neck flanges because of the following reasons:
- On account of their initially lower cost.
- The reduced accuracy needed in cutting the pipe to length.
- The greater ease of alignment of the assembly.
- The calculated strength of slip-on flanges under internal pressure
is approximately two-thirds that of welding neck flanges.
How to measure slip-on flanges?
Take the measurements of:
- OD: Outside Diameter
- ID: Inside Diameter
- BC: Bolt Circle
- HD: Hole diameter
Key Features of Slip-On Flanges :
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
They are generally not preferred for high pressure temperature
Advantages of slip on flanges:
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
they prevent leakage
