1. How should outdoor water pipes and caustic soda pipes in Heilongjiang be insulated? ? ? Is insulation alone sufficient? Will it freeze up if operated intermittently over a long period of time? ? 2. How should outdoor water and liquid caustic storage tanks in Heilongjiang be insulated? ? ?

Leave a name, etc. – anyway, Xinjiang has used electric plates for heating
Use electric heat tracing, or you need to bury the water pipes deep
Electric or steam heating; the permafrost layer is 1.4 meters deep, so deep burial isn’t a viable option.
Then, if plastic pipes are used for the water, can steam be used for heating and insulation? Because could too high steam temperature melt the pipes? ?
That will cause problems; plastic generally performs poorly above 80 degrees, unless it is pipes made of modified tetrafluoroethylene or similar high-temperature resistant materials. Use electric heating; the temperature can be controlled, and it’s simple and durable.
Use electric heating tapes, or you need to bury the water pipes deep below the permafrost layer
