What are Pipe Joints? Flange Pipe Joint | Expansion Pipe Joint

Welcome back MechanicaLEi, did you know that
pipe joints are used to connect a straight pipe, tubing sections and regulate or measure
fluid flow? This makes us wonder, What are pipe joints? Before we jump in check out the
previous part of this series to learn about How pulleys are classified?
Now, The selection of pipe joints depends on pipe sizes, material, flow pressure etc.
A Pipe joint should withstand the pressure of each pipe. There are many types of pipe
joints namely angle joint, cross joint, tee joint, wye joint etc. A special type of pipe
joint is a Flanged joint. It is a connection of pipes, where the connecting pieces have
flanges by which the parts are joined. It consists of two companion flanges, bolted
together and made leakproof by means of a gasket in between the flanges. Shown here
are two pipes being connected by a flange joint held in place temporarily by a press
before bolted together. Another special type of pipe joints are Expansion
joints which are necessary for systems that convey high-temperature substances such as
steam or exhaust gases, or to absorb movement and vibration. A typical joint consists of
bellows of metal, plastic, fabrics or an elastomer such as rubber. A bellows is made up of a
series of convolutions, with the shape of the convolution designed to withstand the
internal pressures of the pipe, but flexible enough to accept axial, lateral, and angular
deflections. Shown here is a pneumatic Blower Inlet and Outlet Rubber Expansion Joint with
it’s bellows made out of rubber. Hence, we saw what pipe joints are, then saw what flange
joints are and then went on to see what expansion joints are?
