May I ask everyone, how should corrosion protection be addressed in environments with trace amounts of dilute hydrochloric acid that require heat pumps?
Thread Content
As stated in the title, one of the intermediates in a project I am working on contains trace amounts of hydrochloric acid. Additionally, its freezing point is relatively high, so hot water is required for heating. If tetrafluoroethylene is used as the lining material, the heat transfer performance will be poor. What other lining materials are available that could provide better heating effects?
Compared to other lined pipes, PTFE lining is a better choice; the intermediate contains trace amounts of hydrochloric acid and has a high freezing point. It is possible to raise the temperature of the intermediate, without relying on hot water for heating, by using insulation instead
