What is Expansion Joint ?

Expansion Joint, also known as a bellows compensator or Metal Compensator, is a key component used to absorb pipeline expansion and vibrations or to compensate for installation deviations of equipment. It is mainly used in pipelines, equipment, and systems, effectively achieving thermal expansion compensation, vibration reduction, noise reduction, and absorption of displacement offsets. Its corrugated structure can provide multi-directional displacement compensation, capable of adapting to thermal and mechanical stresses, and is widely used in industries such as petrochemicals, power generation, and steel.

Materials: Stainless steel 304, 316, and 321, and will customize the most suitable product for your specific application scenario.

Connection Method: Welding, flange types, and metal compensators with limit rods

Classification of Expansion Joint

According to the mode of movement: Axial displacement, angular displacement, lateral displacement

Axial displacement: Axial motion refers to the change in the length of the corrugated pipe from its free length in the parallel direction relative to its longitudinal axis.

Angular displacement: Angular displacement is the rotational displacement of a rotation point along the longitudinal axis of the corrugated pipe.

Lateral displacement: Lateral movement is the relative displacement of one end of the corrugated pipe to the other end in a direction perpendicular to its longitudinal axis.
