What is the difference between stainless bellow flexible joints and expansion joints ?

Stainless bellow flexible joint loop mainly used to absorb the vibration and noise of the pump at the inlet and outlet of the pump.We call them pump connections.

Specifically, our products are divided into tie rod type shockproof joints and net cover type shockproof joints, and tie rod types are divided into welding type and integral molding type.This one-piece type can ensure the cleanliness of the pipeline, and the flange is made of carbon steel. This type of cleaning pipeline can reduce the cost.

Expansion joints are divided into axial expansion joints and lateral expansion joints.Axial expansion joints are mainly used to absorb the expansion and compression of pipelines in the horizontal direction. Lateral expansion joints are also called Vientiane expansion joints. They absorb the displacement in the right-angle direction through the offset of the bellows at both ends. Mainly to ensure the safe operation of the pipeline, it has the following functions: compensating and absorbing the axial, lateral and angular thermal deformation of the pipeline; absorbing equipment vibration and reducing the impact of equipment vibration on the pipeline; absorbing the deformation of the pipeline caused by earthquakes and ground subsidence.
