The corrosive nature of hydrochloric acid is very large, so a more rigorous choice must be made in the material of chemical tanks. And with the concentration of temperature increases. Therefore, choosing a good material for the tank is very important. In general, non-metals are very resistant to corrosion, and in the case where the use temperature is not too high, the choice of plastic is preferable. Here are some other material selection references for chemical tanks.
The processing performance of plastic storage tanks is the best with polyethylene (PE), which can be rotomolded and has a longer service life than other plastic tanks. Other plastics can only be formed by welding. Polytetrafluoroethylene (PTFE) cannot be welded and can only be formed by pressure melting and die casting.
Polyvinyl chloride (PVC) Polyethylene (PE) Polytetrafluoroethylene (PTFE) Polypropylene (PP) Polyolefin (PO) Engineering plastics (ABS) etc. are generally used for plastics. Among them, temperature-resisting and anti-aging are best with polytetrafluoroethylene (PTFE), and polyethylene (PE) is also good with anti-aging, and the temperature resistance performance is relatively poor.
Here, chemical storage tanks are recommended in material rotomolding polyethylene (PE) storage tanks (sub-plastic tanks, steel-plastic composite tanks) as the ideal storage of hydrochloric acid at room temperature and pressure. Rotomolded polyethylene (PE) tanks are available in various concentrations of industrial grade hydrochloric acid and reagent grade hydrochloric acid. Especially suitable for the storage of reagent grade hydrochloric acid. FRP tanks are also commonly used containers for the storage of hydrochloric acid, but he is only suitable for the storage of general industrial grade hydrochloric acid.
