Piping systems are the lifeblood of many heavy industrial markets. Whenever the air, gas, or liquid needs to be moved, there is a huge investment in the piping system to get them from place to place.
Even in a food processing plant, there is a need for special piping systems to move corn syrup from the storage container to the processing area.
Metal expansion joints may experience one or a combination of lateral, axial, angular, or twist. Often the exterior containment system will keep the joint itself from being overstressed to the point of separating.

Two types of metallic expansion joints are available for more advanced and complex pipe systems.
The universal type expansion joint untied has two bellows, connected by an intermediate pipe, to hold through the angular rotations and in pipes that have bigger lateral movements the single type cannot hold.
A gimbal type expansion is for pipelines that make varied movements; and like the hinge type, it needs to be installed in twos and threes to adequately withstand the constant thrusting and moving of the pipes. Two pairs of gimbal arms and pins will protect the metallic joint from being damaged and overexerted.
The pressure balanced type joint is for very large pipes or pipe systems that operate under larger amounts of pressure flowing through the piping.
These pipes will need anchors to be installed to prevent the metallic expansions joints to be thrust beyond their capacity. Where an anchor cannot be installed, then a balance type joint will be used instead.
Each joint has its limits. There are engineering solutions to a number of inherent weaknesses in the system expansion joint.
If the bellows is required in high-pressure situations, an exterior space can be added to equalize pressure inside and outside so that the weakness of the bellows structure is less of an issue.
