Can rigid PVC be used as an anti-HCl corrosion material?
It depends on the concentration and temperature. 20% hcl at room temperature is fine.
2# The environment of Pangang Xiaoli contains hydrochloric acid mist and a small amount of HCl gas.
The concentration is below 35% and the corrosion resistance is very good within the temperature of 60 degrees. It can be used when the concentration is above 35% and the temperature is not high. When it reaches above 60 degrees, it is not suitable for soft materials. The hard material is at the boundary between usable and unusable. It needs to be decided through specific experiments. Is the poster using it as a chlorine drying tower?
4# In addition to high temperatures, does rigid PVC have any effect on low temperatures, such as the normal low temperature environment in the north? And how long is the general service life?
Under low temperature conditions, such as minus ten degrees Celsius in northern winter, the impact resistance of hard PVC is poor. We know that there is no problem with installing HCL at normal concentrations at room temperature for 20 years.
