What material is suitable for use when wastewater contains hydrogen bromide and bromine?
Fiberglass, enamel, steel-lined PTFE, glass, PE, PP
Equipment: enamel, steel lining (PTFE, PE, PP, etc.), FRP; the choice is made based on other components as well. If there are special components, it is recommended to conduct material testing. Pipes: Steel-lined (PTFE, glass, etc.); non-metallic pipes are not recommended as they tend to deform easily.
Will non-metallic pipes be corroded by bromine? Ordinary plastics
If you have no experience in using it, you can consult some materials or seek advice from plastic manufacturers. Those with experience know that enamel material presents no problems at all, but the factor of easy damage associated with purely non-metallic materials must be taken into account, as well as emergency plans in case the lining of such equipment is damaged and bromine comes into direct contact with iron.
It is recommended to use steel-lined PTFE pipes; if cost savings are a concern, glass pipes can be used.
