ASME A182 F316 / 316L Slip On Pipe Flanges NPT RF 150LBS High
Strength Size1/2'-24'
Din Standard Flanges
Pipe Flanges are widely used as a popular category of pipe
fittings. A flange is used to mechanically connect two pipes
together. It can also be used to mechanically connect a pipe to a
tee, valve, choke or any other piece of equipment. Flanges are
available in round, square, and rectangular shapes. In some cases,
flanges are usually in the shape of a ring or a plate to form a rim
at the end of a pipe when fastened to the pipe. This is an example
of closet flange. A flange can also be a plate for covering or
closing the end of a pipe. This is a blind flange. Thus, flanges
are considered to be projecting or internal components which are
used to support mechanical parts. They are like rims which are used
to strengthen the mechanical part or they are a means of attaching
that part to another part or surface.
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.
Threaded Flanges
Threaded Flanges are used for special applications. They can be
assembled without welding and can be used in extremely high
pressure services--at or near atmospheric pressure--where alloy
steel is essential for strength. Threaded flanges are not suited
for conditions involving temperature or bending stresses, or under
cyclic conditions where leakage through the threads may occur.
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.
Lap Joint Flanges
Lap Joint Flanges are used with lap joint stubs. Lap joint flanges
are commonly used in carbon or low alloy steel piping systems that
need to be frequently dismantled for inspection and cleaning. They
should not be used at any points where severe bending stresses
occur.
We offer high quality DIN flanges that conform to the standard
specifications of DIN
- Deutsches Institut for Normung (German Institute for
Standardization). These din standard flanges can be availed in
different material specifications including carbon steel, stainless
steel and alloy steel. Available at the most reasonable prices, our
steel DIN flanges can work efficiently under high temperature and
pressure
Designs of flanges:
A wide variety of flange designs are available. They are available
in various shapes and sizes. Some of the popular designs are as
follows:
- Butt weld
- Socket weld
- Captive
- Split
- Square
- Round
- Rectangle etc.
Custom shapes and sizes are also manufactured by numerous
manufacturers. Various pipe flanges include machining details such
as gasket surfaces, facing details, non-standard drilling, bevel
and radius edges, o-ring grooves and raised or recessed faces. Some
typical designs on flanges faces are shown below.

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.
