In general: cold water pipes (white) are used for domestic water supply, condensed water, oxygen, compressed air, and other chemical liquids; hot water pipes (orange) are used for heating piping systems, floor radiant heating piping systems; gas pipes (yellow) For natural gas, liquefied gas, gas pipeline. The connection of the aluminum-plastic composite pipe is to pass a strict pressure test to check whether the connection is firm. The second is to prevent frequent vibration and loosen the pipe fittings. The third is to leave enough installation in the length direction to avoid pulling off. The applicable temperature of the cold water pipe is -40-60℃, the applicable pressure is 1Mpa, the applicable temperature of the hot water pipe is -40-95℃, and the applicable pressure is 1Mpa; the applicable temperature of the gas pipe is -40-60℃, and the applicable pressure is 1Mpa, 1Mpa Equivalent to 10 kg of water pressure.
