Material selection reference of hydrochloric acid storage tank
Hydrochloric acid is very corrosive, so a rigorous selection of the material of the hydrochloric acid storage tank is needed. It also increases with increasing concentration temperature. Therefore, it is important to choose a good material for the storage tank. Generally, non-metals have good corrosion resistance, and plastics are ideal when the temperature is not too high. Below are some other material selection references for hydrochloric acid storage tanks.
The processing performance of plastic storage tanks is best made of polyethylene (PE), which can be formed by rotomolding and has a longer service life than other plastic storage tanks. Other plastics can only be welded. Polytetrafluoroethylene (PTFE) cannot be welded and can only be used by pressure melting, die casting and other technologies.
Plastics generally use polyvinyl chloride (PVC) polyethylene (PE) polytetrafluoroethylene (PTFE) polypropylene (PP) polyolefin (PO) engineering plastics (ABS) and so on. Among them, polytetrafluoroethylene (PTFE) is the best for temperature and anti-aging, and polyethylene (PE) is also very good for anti-aging, and the temperature resistance is poor.
Here, rotomolded polyethylene (PE) storage tanks (divided into all-plastic storage tanks and steel-plastic composite storage tanks) are recommended for the storage of hydrochloric acid at room temperature and pressure. Rotomolded polyethylene (PE) storage tanks can hold various concentrations of industrial-grade hydrochloric acid and reagent-grade hydrochloric acid. Especially suitable for the storage of reagent grade hydrochloric acid. FRP storage tank is also a common container for storing hydrochloric acid, but it is only suitable for storing general industrial-grade hydrochloric acid.
