FLANGES- General Information
A Flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework system. It also provides easy access for cleaning, inspection or modification.
Flanges are usually welded or screwed into such systems and then joined with bolts.

Flange Types
•Slip-on
•Socket weld

Flange Types
•Weld neck
This flange is circumferentially welded into the system
This flange is circumferentially welded into the system
at its neck which means that the integrity of the butt
welded area can be easily examined by radiography.
The bores of both pipe and flange match, which
reduces turbulence and erosion inside the pipeline.
The weld neck is therefore favoured in critical
applications
•Slip-on
This flange is slipped over the pipe and then fillet
welded. Slip-on flanges are easy to use in fabricated
applications.
•Blind
This flange is used to blank off pipelines, valves and
This flange is used to blank off pipelines, valves and
pumps, it can also be used as an inspection cover. It
is sometimes referred to as a blanking flange.
•Socket weld
This flange is counter bored to accept the pipe before
being fillet welded. The bore of the pipe and flange are
both the same therefore giving good flow
characteristics.
•Threaded
This flange is referred to as either threaded or
This flange is referred to as either threaded or
screwed. It is used to connect other threaded
components in low pressure, non-critical applications.
No welding is required.
•Lap Joint
These flanges are always used with either a stub end
or taft which is butt welded to the pipe with the flange
loose behind it. This means the stub end or taft always
makes the face. The lap joint is favoured in low
pressure applications because it is easily assembled
and aligned. To reduce cost these flanges can be
supplied without a hub and/or in treated, coated
carbon steel.
•Ring Type Joint
This is a method of ensuring leak proof flange
connection at high pressures. A metal ring is
compressed into a hexagonal groove on the face of
the flange to make the seal. This jointing method can
be employed on Weld Neck, Slip-on and Blind
Flanges.
