What are the selection parameters of stainless steel ripple compensator

The selection of stainless steel ripple compensator directly affects the effect of absorption displacement of the ripple compensator after installation, and the selection needs to implement the pressure, temperature, medium, displacement and connection mode of the compensator.

Stainless steel ripple compensator in the selection of the need to pay attention to the following parameters, including temperature range, working pressure, medium type, medium flow, displacement, connection mode, etc.

Temperature range, according to the working temperature of the pipeline system, the material suitable for the temperature is selected, so that the stainless steel ripple compensator can work stably within the temperature range. The working pressure of the pipeline system, select the compensator that can withstand the pressure to make it stable operation. Understand the chemical nature of the cutoff in the pipe, whether it is corrosive, and the degree of corrosion. Thus according to the medium selection of suitable bellows material. The flow rate of the medium is related to whether it is necessary to set the guide cylinder and the selection of the wall thickness of the guide cylinder, and the flow rate during the operation of the ripple compensator needs to be considered. Understand whether the conveying medium will accumulate or solidified, so that measures can be taken to prevent the medium from condensing in the bellows and avoid the failure of the bellows caused by the condensation of the medium. Determine the displacement of pipeline system, including axial, lateral and angular displacement, and select compensators with corresponding compensation capabilities. When the compensation amount is uncertain, the wave number of the bellows can be understood, considering the use of the bellows, the fatigue number under the action of stress, and the corresponding wave number suitable for small deformation stress and anti-fatigue can be selected.

Connection mode can be selected flange or welding two ways, flange for frequent disassembly and maintenance of the pipeline system, the use of flange connection is easy to install and disassemble. The welding method is suitable for the working environment with high sealing requirement. If there is vibration or shock in the working condition, the amplitude and frequency of the vibration source should be understood to avoid resonance between the bellows of the compensator and the system.

The selection of stainless steel ripple compensator directly affects the effect of compensation displacement after installation, and the reference data should be communicated in detail to the compensator manufacturer before selection.
