Dalian compressed air pipeline installs the pipes, pipe fittings, valves, etc. in place according to the design requirements, so that the compressed air can be delivered to the user at the specified working pressure. The installation procedures include pipe selection, pipe processing, pipe laying, pipe connection, pipe test and pipe purging. Dalian compressed air pipe processing includes pipe cutting and bending. (1) The pipe is bent. The method of cold swab or hot withdrawal can be adopted. The method of cold withdrawal shall be adopted for pipe diameter DG ≤ 150mm, and the method of hot plunger shall be adopted for pipe diameter DG > 150mm. When there is no cold swab machine, the small diameter pipe can also be swabbed by heat.

The compressed air pipeline shall meet the user's requirements for compressed air flow, pressure and quality. The selection of the laying method shall be determined through technical and economic comparison according to the local terrain, geology, hydrology and meteorology. The compressed air pipeline in the plant (mine) area in hot and warm areas should be laid overhead. Cut off valves, pressure gauges and flow meters shall be provided for compressed air pipelines at the places where the gas consuming buildings are located. Oil water separator shall be set for the pipeline conveying saturated compressed air. For users whose compressed air load fluctuates greatly or whose supply pressure is required to be stable, it is advisable to set an air storage tank or other pressure stabilizing device nearby.

The air medium to which the compressed air pipeline gas belongs should be marked with light gray. More careful friends can find that one is the petrochemical industry standard and the other is the national standard; One is a separate industry standard, and the other is a national mandatory standard. We can easily confirm that the color of compressed air pipe should be light gray. The selection of the installation site of compressed air pipeline is most neglected by the staff.

Often, after the air compressor is purchased, it will find a position at random and use it immediately after piping. There is no prior planning at all. However, such a hasty result will lead to failure of air compressor, difficulty in maintenance and poor quality of compressed air in the future. Therefore, proper installation site is the prerequisite for correct use of the air compression system.
