Loose flange stainless steel metal expansion joint

Loose flange stainless steel metal expansion joint is a compensation device used to absorb the dimensional changes of pipelines, conduits or containers caused by thermal expansion and contraction by using the effective expansion and contraction of the elastic elements of the bellows expansion joint. a compensation element. Absorbs axial, lateral, and angular displacements.

Due to the different compensation forms of different types of corrugated expansion joints, there are mainly axial, lateral, angular and combined compensation methods. For corrugated expansion joints with multiple displacements at the same time, the various displacements should be synthesized to obtain the total equivalent axial displacement. The detection is for the total equivalent axial displacement. That is to say, the detection of the nominal displacement of the ripple compensator is the detection of the total equivalent axial displacement.

The nominal displacement of the stainless steel expansion joint is actually the given nominal displacement deformation capacity of the bellows. For expansion joints (compensators) and compensators made of bellows, it is usually called the compensation amount, which reflects the ability of the bellows to absorb the displacement of the system, and represents the maximum compensation ability of the product under certain conditions. When the bellows is working normally, it must absorb the displacement of the system and generate displacement deformation, and at the same time, it must ensure a certain number of normal safe working displacement cycles. Therefore, when the bellows is designed, according to the displacement size that each wave can bear, a certain number of corrugations is designed. When each wave is evenly subjected to the displacement load and there is no local overload, the bellows expansion joint can work normally. . When the design is reasonable, a certain number of design working displacement cycles can be guaranteed. In the JB/T 6169-92 "metal corrugated pipe" standard, the testing of this performance is specified.
