How is the compensation amount of the ripple compensator calculated?
Many customers will provide a compensation amount data when ordering the ripple compensator. What is the compensation amount? How is the compensation calculated? Now, let's learn about the compensation amount of the corrugated compensator: the compensation amount of the corrugated compensator is the allowance required for the deformation of the pipeline due to the influence of temperature, which is the same as the allowance between rails. Here, it mainly refers to the expansion range of the elastic elements of the pipeline. It refers to the total tension and compression of the expansion device. And a minus sign (-) for stretch and a plus sign (+) for compression. The compensation amount is the allowance required for the deformation of the pipeline due to the influence of temperature, which is the same as the allowance between rails
In the case of axial compensation of pipeline, it also refers to expansion and contraction. If the pipeline has axial, radial and angular displacement, it is generally expressed by compensation.
Here, it mainly refers to the expansion range of the elastic elements of the pipeline. It refers to the total tension and compression of the expansion device. And a minus sign (-) for stretch and a plus sign (+) for compression.
Calculation formula of compensation amount: calculation formula of compensation amount: X=a * L * △ T
X Pipe expansion
A is the linear expansion coefficient, taken as 0.0133mm/m
L Length of compensation pipeline (distance between fixed supports of compensation pipeline required)
△ T is the temperature difference (medium temperature - ambient temperature during installation)
For example: for a heating pipeline, the straight pipeline between two fixed supports is 50 meters long and the water temperature is 90 degrees. The ambient temperature when installing the compensator is 15 ℃. Then the pipeline expansion of this section is 0.0133 * 50 * (90-15)=49.875mm. Then this value is a low requirement for the compensation amount of pipeline elastic elements (also known as expansion joint, compensator, expansion joint).
Shanghai Dongfeng Jianqing kindly reminds everyone that correctly calculating the compensation amount of the pipeline plays a vital role in the safe operation of the pipeline, which is something the design department should pay attention to.
