Is there any national standard for the wall thickness of R410 copper tubes for air conditioning?
Design and construction installation of 07K506 multi connected air conditioning system
There is no standard, air-conditioning manufacturers will make corresponding design,.R410 work pressure is high, high pressure can be more than 2.5MPA. Copper wall thickness of not less than R22, must be more than 0.55MM
In general the central air-conditioning construction specifications will be required for wall thickness. In general, as long as the theory can withstand 40 kilograms of pressure on the line
No standard,But it's thicker than regular F22 copper tubes..
