Due to the large amount of coal ash and corrosive gases in the working environment of the GJCT series gap measurement device, it is necessary to seal the gap probes, transmitters, etc. All pipelines and connections need to be sealed to prevent air leakage and ash emission. This can effectively extend the service life of the device.

The air pipe GJCFB-15 is a flexible corrugated pipe made of alloy metal material. It has a certain degree of elasticity and scalability. In case of Thermal expansion, vibrationor deformation of the pipeline system, the flexible corrugated hose can freely expand and bend, absorb the displacement and deformation of the system, so as to maintain the tightness of the gap measurement system.

In addition, the metal corrugated pipe GJCFB-15 can also absorb vibration in the pipeline system, reduce the impact of vibration on the pipeline system and connectors, and reduce the risk of damage caused by vibration. However, considering the harsh working conditions in the air preheater, it is necessary to regularly inspect and maintain the bellows to ensure its normal operation and sealing performance, in order to improve the safety and reliability of the system.
