Inorganic salt aqueous solutions: Commonly used ones include aqueous solutions of calcium chloride and sodium chloride. Stainless steel is prone to corrosion; are carbon steel pipes a suitable choice? Which type of pipe is the best!
We use carbon steel pipes, and they won’t crack within five years!
We also use carbon steel pipes; during the major maintenance carried out in the year when the vehicle was 30 years old, some of the main pipes were replaced as part of the renovation of the chiller system.
Our company also uses carbon steel pipes.
Cold saline causes severe corrosion of stainless steel pipes; in previous designs, material grade 20# was used, and regular maintenance ensured no major issues during normal operation.
Carbon steel seamless pipes are sufficient; using 16Mn is a bit excessive and it’s not easy to find.
