Answer: (1) The gas pipeline connected to the machine must be cleaned before installation. There should be no floating rust, slag, welding beads and other debris.
(2) The maximum allowable working pressure of the gas pipeline and pipe fittings should exceed 1.5 times the rated exhaust pressure and be greater than the set pressure of the safety valve.
(3) The main pipeline should have a certain inclination（1~2℃）to facilitate the centralized discharge of condensate in the pipeline.
(4) The pipeline pressure drop must not exceed 5% of the set pressure of the air compressor. The pipe diameter should not be reduced arbitrarily. If the pipe diameter must be reduced or enlarged, a tapered pipe must be used. Otherwise, turbulence will form at the joint, resulting in a large pressure loss.
(5) If the system gas consumption fluctuates greatly, it is recommended to install buffer and purification facilities to reduce the number of load operations of the air compressor. The ideal configuration is: air compressor + gas storage tank + dryer.
(6) The compressed air flow rate in the delivery pipe should be within 15m/s to avoid a large pressure drop; elbows and valves of all kinds should be reduced as much as possible in the pipeline to reduce pressure loss.
(7) When there are many gas-using equipment and they are relatively scattered, the main pipeline should surround the entire plant, so that any location can obtain compressed air in two directions to reduce pressure drop.
(8) The branch pipeline must be led out from above the main pipeline to prevent condensed water in the pipeline from flowing to the gas-using equipment.
