May I ask whether carbon steel and plastic can be used for outdoor pipes and valves in areas with temperatures of minus 20 degrees Celsius? Are there any regulations regarding the materials to be used?
At temperatures of minus 20 degrees Celsius, steel should be used for the materials of outdoor pipes and valves in the northern regions; plastics cannot be used. For details on material selection, refer to CJJ34-2010.
There must be standards for selecting materials; I’ve seen ones made of carbon steel.
It depends on the intended use; there is also low-temperature carbon steel
In my opinion: carbon steel is fine, but plastic is not
Carbon steel can be used at temperatures below minus 60 degrees. When it comes to plastics, consider their level of hazard; using plastic for draining water is not a big issue – just fix any leaks that occur. Hazardous chemicals require metal containers
