Working principle

Corrugated compensator is a kind of compensation device, which uses the effective expansion deformation of the elastic elements of the corrugated compensator to absorb the size change caused by the thermal expansion and cold contraction of the pipeline, conduit or container. It can absorb axial, transverse and angular displacement.

Testing

Due to the different compensation forms of different types of bellows compensators, there are mainly axial, lateral, angular and combined compensation ways. For the corrugated compensator with many kinds of displacement, it is necessary to synthesize all kinds of displacement to get the total equivalent axial displacement. The detection is for the total equivalent axial displacement. In other words, the detection of nominal displacement of corrugated compensator is the detection of total equivalent axial displacement.

The nominal displacement of the general-purpose bellows is actually the capacity of the bellows to deform at the given nominal displacement. For expansion joints (compensators) and compensators made of bellows, they are usually called compensation amount, which reflects the ability of bellows to absorb the displacement of the system and represents the maximum compensation ability of the product under certain conditions. When the bellows works normally, it should absorb the displacement of the system and produce displacement deformation. At the same time, it should ensure a certain number of normal safe working displacement cycles. Therefore, in the design of bellows, according to the displacement that each wave can bear, there is a certain number of corrugations. When each wave is uniformly bearing displacement load, and there is no local overload, the bellows can work normally. When the design is reasonable, it can ensure a certain number of design working displacement cycle life. In JB / T 6169-92 "metal bellows" standard, this performance test is specified.

Calculation

Calculation of thermal deformation of pipeline

Calculation formula: x = a · L ·△ t

X pipe expansion

A is linear expansion coefficient, taking 0.0133m m/m

L length of compensation pipeline (distance between fixed supports of required compensation pipeline)

△ t is the temperature difference (medium temperature - ambient temperature during installation)
