What are the requirements for compressed air and nitrogen piping arrangement and laying?

A: Compressed air, nitrogen piping layout and laying requirements are as follows.

1) Generally adopt branch arrangement, or radial and ring arrangement. Pipeline laying can be overhead, trench, buried according to the situation.

2) Pipelines should be set up on the oil and water discharge devices, pipeline slope should not be less than 0.002.

3)Compensation for thermal expansion should be considered for the pipeline in the plant.

4) Pipeline pressure fluctuations or user requirements for gas supply pressure stabilization, it is appropriate to set up a nearby gas storage tank or other pressure stabilization measures.

5) Piping is generally appropriate to use welding, equipment and valves, etc. can be flanged and threaded connections.

6) The arrangement and laying of pipelines in the workshop: 1 the entrance of pipelines should be generally equipped with entrance devices, including shut-off valves, safety valves, pressure-reducing valves and oil-water separators, etc.; 2 branch pipes leading from the upper part of the workshop trunk pipe should be led down along the wall or along the column, and the cut-off valves should be installed at a distance of 1.2-1.5m from the ground, and then the rubber hose or steel pipe can be used for connection with the equipment, and the steel pipe is generally directly buried; 3 the lowest point of the pipeline and the end of the pipeline should be installed with water collectors. Water collector should be installed at the end of the pipeline;
