Understanding piping works and
its functions is not an easy task! There are a lot
of basic things and requirements which a person need to fulfill to get a
complete grasp of this field.
Let’s take an example of pipe fittings and basic differences between each. Usually, people assume that there is not much
difference between pipe nipple and
coupling. In other words, they don’t count the minor differences between both
as they found both usable in pipe fittings, and plumbing works. They may have a
point in terms of general use, but technically, there is a great difference
between both.
However, we have collected some
best points about both pipe nipple and couplings, by reading which you’ll learn
the how they distinguish from each other.

Differences between Pipe Nipple & Pipe Couplings
Pipe
Coupling
Pipe coupling is referred to as a
short length of pipe or tube with a socket connected at one end and sometimes
at both ends which helps to connect two pipes or tubes. Welded (like steel),
brazed, or soldered (like copper & brass) together.
A pipe coupling is a
kind of pipe fitting which is used to connect two or more pipes together to
retain their continuity or resistance for a long time. You can reduce pipe
couplings into internal diameter if going to use it for different pipe sizes;
whether it is T shape, cross-shaped – to join more than two pipes, or
in angle shape for making bends.
These joints if
connected or installed rightly, then it can offer an excellent rigidity and
sealing characteristics without any change in material and functioning of
pipes. I will suggest you prefer flexible pipe coupling over other due to its
following benefits;
·
Easy installation
·
Versatility
·
Special eccentric designs
·
Chemical resistance
·
Made with leak-proof
technology
Pipe
Nipple
Pipe nipple is a most popular
category of pipe fitting. It is a straight pipe with male threads on both ends.
This kind of fitting enables plumbing to
be connected to a water heater or other plumbing.
The pipe nipples are usually
recommended for discharging low-pressure liquids, or for suction service of
various compatible liquids, but it is not applicable to use for nitrogen, air,
or steam.
The length of this pipe fitting
is typically determined by the general length with threads. It might have a
hexagonal segment in the middle for torque to get a handle on (It can also be
referred as “hex nipple” or it might also be made from a short piece of pipe (also
known as barrel or pipe nipple).
A “close nipple” has no
unthreaded region; when screwed firmly between two female fittings, almost no
of the areola stays uncovered.
