Product features:
It is a flexible connection component used in pipeline systems to absorb thermal expansion, vibration and mechanical movements.
It is composed of three concentric metal corrugated layers,
usually made of materials such as stainless steel,
and it is stronger and more flexible compared to a single-layer design.
The outer and inner layers act as protective barriers to contain the medium,
while the middle layer contributes to the overall pressure resistance and stability.
This configuration enables the joint to adapt to multiple directions of movement,
including axial, lateral, and angular deformation,
and still maintain its sealing performance under different temperatures and pressures.
Such expansion joints are commonly used in industrial applications, including power plants, chemical processing,
oil and gas pipelines, and HVAC systems.
They help to reduce the stress on pipeline components and extend the lifespan of the systems.
Other features may include an internal lining or an external cover plate to reduce erosion or wear,
as well as pull rods or limit rods to control movement and withstand pressure thrust.
