Pipe Thread
- Male
In this category, tapered
pipe threads like NPT, BSPT
etc are used which are
basically for the purpose of
sealing without gaskets.
Pipe Thread
- Female
Pipe Thread - Female is same
as Pipe Thread - Male. Here
too, tapered pipe threads
such as NPT, BSPT, etc are
used which is specifically
for sealing without gaskets.
Straight
Thread -
Male Straight pipe threads
such as UNC, UNF, ASME, etc
form Straight Thread - Male.
Straight
Thread -
Female Straight Thread -
Female also includes
straight pipe threads such
as UNC, UNF, ASME, etc.
Plain End
Plain End is used to insert
into the bell end of the
connecting pipe.
Bell /
Socket / Flare
It is the end length of
increased diameter into
which a pipe end can be
fitted.
Flange
There are two types of
flanges, circular and
square. These are used to
connect fitting, typically
via bolting or welding.
Compression
Fitting
Compression fitting includes
compression nut and ferrule by
which it connects to a mating
pipe.
Pipe Clamp End
Pipe Clamp End is designed in
such a way so that it is
attached to run on pipe or other
fitting.
Barb / Rib
Barbs and ridges comprise
fitting ends. They connect only
non-rigid pipe or hose, or
sometimes used with a clamped
end.
Groove
Groove is
for the
installation
of a coupling feature such as an
o-ring or elastomeric seal.
Features Criteria
Lined Pipe
Fittings
In order to protect pipes
against the unwanted
deterioration and to enhance
the properties of the
fittings, there are a number
of lining options that are
avaiable in the market.
Lined pipe fittings are
manufactured with an
integral lining that are
mostly made from engineered
polymers used with process
materials or with other
applications like food
processing. It is done
taking into consideration
the importance of
cleanliness and hygiene
factors.
The lining material selected
for the service is generally
inert and has suitable and
broad temperature ranges.
Most severe service
applications can be handled
by using corrosion and
abrasion resistant ceramic
materials. Some of the
popular lining products are
PP, PVDF, ECTFE, ETFE, PTFE,
PFA, MFA etc.
Plated Pipe
Fittings
Pipe fittings are that are
plated with different
materials in order to impart
the required properties are
called plated pipe fittings.
These are mostly plated with
materials such as nickel and
chrome.
These platings are used to
prevent corrosion and also
to improve the exterior
appearance of the pipe. They
also help in increasing the
longetivity of the pipes and
it is enhanced significantly
if the plating is done with
a durable material of good
quality.
Underground
Rated Pipe Fittings
These pipe fittings are
designed and constructed for
underground application.
Since the application of
these pipes is below the
ground, some rules have been
formulated. It is mandatory
that underground piping
shall be buried not less
than 18 inches below the
surface of the ground unless
otherwise protected, and
shall be adequately coated
or otherwise protected
against corrosion. Pipe
coated as follows will be
considered acceptable if it
is:
- Clean and prime.
- Coated with asphalt
enamel.
- Wraped with forty-pound
felt or Kraft paper.
Though materials like PVC or
CPVC can be used, it is
advisable to use ABS as it a
heavy-duty plastic pipe and
can successfully meet the
requirements of underground
drainage and sewer
applications.
