This section provides an overview for expansion joints as well as their applications and principles. Also, please take a look at the list of 78 expansion joint manufacturers and their company rankings.
Table of Contents
An expansion joint is a type of pipe fitting that connects, changes the direction of, and branches pipes, and is a movable pipe fitting that can absorb axial expansion and contraction of pipes due to temperature changes.
Expansion joints not only connect pipes. They also absorb the expansion and contraction of pipes (due to changes in the temperature of the fluid that passes through the pipes, and the outside temperature of the pipes). Adjust misalignment of pipes (due to ground subsidence, dampen vibration of pumps, turbines, compressors, and other equipment) and protect pipes from mechanical trouble.
Expansion joints are used in various fields as direct piping fittings because they connect pipes and have the function of preventing expansion, contraction, misalignment, and bending of pipes due to temperature changes, ground subsidence, vibration, and other factors.
Specifically, it is used in lifelines such as water pipes, drainage pipes, and gas pipes. As well as in piping, exhaust/exhaust gas/ventilation systems, dust collection, and soot collection systems in oil and chemical plants, steel mills, and power plants, incinerator air ducts in waste disposal facilities, vacuum drive units in semiconductor manufacturing plants, and exhaust systems of diesel engines in ships. They are used to absorb pipe expansion and contraction, absorb misalignment, dampen vibration, and prevent ground subsidence and earthquakes.
There are three types of expansion joints: sleeve type, bellows type, and vented type.
In addition, the fixed point is subject to the spring reaction force when the bellows are displaced and the static thrust force that tries to extend the bellows in the axial direction when the internal pressure increases. Therefore, the fixed point must be strong enough to withstand these forces.
