Quality Guarantee for Large Projects:
We understand the requirements of terminal users in the Oil, Gas, and Power
industries. Every Slip-On flange undergoes 100% visual and dimensional
inspection.
Types of Slip-On Flanges and Their Applications
SO flanges are available in two main types, each designed to cater to specific
requirements and applications within piping systems:
Standard Slip-On Flanges:
Standard or raised-face SO flanges have a raised face on the sealing surface.
They are highly suitable for low-pressure applications where the bolt-
tightening force can compress the gasket adequately to prevent leakage.
Lap Joint Slip-On Flanges
Lap joint SO flanges have a flat face with a separate backing flange. They are
commonly used in systems requiring frequent dismantling, thermal expansion, or
contraction applications.

Cost-Effectiveness:
Genera , lly, slip-on flanges are more cost-effective than other types of flanges,
such as weld neck flanges, due to their simpler design and installation
process.
Material:
They can be made from various materials, including carbon steel, stainless
steel, and other alloys, depending on the application requirements.
Limitations:
While slip-on flanges are versatile, they may not be suitable for high-pressure
applications due to the potential for leakage at the weld joint.
Slip On Flange vs Weld Neck Flange
The strength for internal pressure of the Slip-On Flange is two-thirds of Weld
Neck Flange.
Durability life is 1/3 of the WN flange.
2 fillet welds are required for the SO flange, one inside and one outside of
the flange.
A space shall be reserved between the end of the pipe and the end of the flange
during welding work, to avoid damage to the flange face.
The slip-on flange has to connect with a pipe first, then connect to a fitting.
(Combination of flange+elbow, or flange+tee not available, since the fittings
are not in a straight end, it can not slide completely into the flange bore. )
Slip-on flanges are usually cheaper than Weld-Neck flanges (welding neck
flange), which is why many customers prefer to choose them. It is one of the
commonly used flanges for low-pressure, medium-temperature piping systems.
On the other hand, since the flange bore is larger than the pipe diameter, it
usually requires more welding work than the other flanges. So the durability is
not as long as the welding neck flange; all of these factors should be
considered before choosing the right flange.
