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 selection of the installation site of compressed air pipeline was 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.

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.
