At present, the aluminum alloy Dalian compressed air pipeline has been widely used in the compressed air system. Because it is clean, light, quick to install, reusable, and not easy to rust, it has obvious advantages over the traditional seamless steel pipe.

In most industrial systems, especially in thermal power plant systems, air compressors, dryers, dryers and compressed air pipeline systems are essential and very important basic production equipment, which are used to provide power for valve switches, purging equipment and instrument detection.

Among them, the compressed air pipeline in Dalian is the pipeline that transmits the compressed air generated by the air compressor, the cold dryer and the dryer and is used for the pneumatic system and the pneumatic device. In order to avoid failure of the pneumatic device, drainage operation is required to discharge the condensed water in the compressed air system.

In the compressed air pipeline in Dalian, due to the long pipeline, many branch pipes and the defects of the cold dryer or dryer, it is often found that the water in the compressed air pipeline causes the solenoid valve to water, and even the air cylinder of the pneumatic valve to water, which causes the valve to fail to open and close normally, which greatly affects the service life of the valve and the safe and stable operation of the system. The ash humidity of the ash conveying system increases, which causes serious wear of the ash conveying system and makes the ash conveying system difficult.
