Thread: Hydrochloric acid

    What material can I use to protect surfaces against (20% concentration by weight) hydrochloric acid? Maximum operating temp is less that 50 degrees Centigrade.

    Thanks.

    Jess.

  2. Hydrochloric Acid

    Hi Jessica,

    The following materials are classified as unaffected by 20% Hydrochloric acid in pumping applications:

    Carbon
    Ceramic
    Epoxy resin
    Natural rubber
    Nylon
    Polypropylene
    Polythene
    Teflon
    Viton

    Be careful with the plastics at temperatures above 25 degrees Centigrade.

    Regards,

    Mike Griffiths.
