Forged S31254 3/4'' Class 300LB Slip On Pipe Flanges ASTM A182 F44
254MO Flanges Size1/2'-24'
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
strength
they prevent leakage
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
bolting holes.
They are generally not preferred for high pressure temperature
environments.

Most used pipe flange
Slip on pipe flange is suitable for the lower pressure, general
temperature and normal circumstance pipelines. It is easy to
install and with lower cost/price, has been most used in the common
industries.
Slip-on Flanges
Slip-on Flanges have a lower initial cost than welding neck flanges
because they require less accuracy in cutting pipe to length, and
they provide a greater ease of alignment in assembly. However,
their calculated strength under internal pressure is approximately
2/3's the strength of welding neck flanges, and their life under
fatigue is 1/3 shorter. Slip-on Flanges are limited to 1/2" to 2½"
sizes in 1500lbs standard.
Weld Neck Flanges
Weld Neck Flanges have a long tapered hub and gradual transition of
thickness in the region of the butt weld joining them to the pipe.
The tapered hub provides important reinforcement to the flange and
resistance to dishing. This type of flange is preferred for severe
service conditions resulting from high pressure, sub-zero or high
temperatures.
Blind Flanges
Blind Flanges are used to blank off the ends of piping, valves and
pressure vessel openings. Blind Flanges can handle high stress from
internal pressure and bolt loading since the maximum stresses in
the blind flange are bending stresses at the center.
Socket Weld Flanges
Socket Weld Flanges were developed for use on small size high
pressure piping. With an internal weld, socket weld flanges are
stronger and have greater fatigue strength than double welding a
slip-on flange. Smooth bore conditions can be easily attained by
grinding the internal weld. This flange is commonly used in
chemical process piping.

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.
