Compensation formula:
Compensation calculation formula: X=a*L*△T
x is the expansion of the pipeline
a is the coefficient of linear expansion, take 0.0133mm/m
L Compensation pipeline (the distance between the fixed supports of the compensation pipeline) length
△T is the temperature difference (medium temperature - ambient temperature during installation)
The compensation amount is the margin required for the deformation of the pipeline due to the influence of temperature, and it is the same as the margin left between the rails.
In the case of axial compensation of the pipeline, it also refers to the amount of expansion and contraction. If the pipeline has axial, radial and angular displacement, it is generally expressed by the compensation amount.
Here, it mainly refers to the expansion and contraction range of the elastic element of the pipeline. It refers to the sum of the extension and compression of the telescopic device. And a minus sign (-) for tension and a plus (+) for compression.
The compensation amount of the corrugated compensator is the margin required for the deformation of the pipeline due to the influence of temperature. It refers to the sum of the extension and compression of the telescopic device. And a minus sign (-) for tension and a plus (+) for compression.
For example: a heating pipeline, the length of the straight pipeline between the two fixed brackets is 50 meters, and the water temperature is 90 degrees. The ambient temperature when the compensator is installed is 15 degrees. Then the pipeline expansion of this section of pipeline is: 0.0133*50*(90-15)=49.875 mm. Then this value is the minimum requirement for the compensation of the elastic elements of the pipeline (also called expansion joints, compensators, expansion joints).
The axial thrust F of the axial compensator is calculated by the following formula:
Fx=Fp+Fm+Fs N
In the formula: Fp——the thrust generated by the internal pressure, N
FS - elastic reaction force compensated by bellows,N
Fm——Frictional force of pipe movable support,N
