    I know about the great properties this material has, but i want to know if it's acid resistant and how much it costs.

    Here's my problem:
    I need to get a steady flow of sulfuric acid 98% from one place to another (about 50m). What pumps should i use? What sort of pipes should i use?

    What do you recomend?

    Thank you in advance,
    andrefonsecaa

    Teflon tubing and H2SO4 are perfectly compatiblle, no acid will harm it. LGM is mistaken.
    Expensive , yes. Around $125 for 25 feet,3/8 inch.
    alternative is a TFE lined tygon fromulation SE-200 $150 for 50 feet.
    Will also need an acid resistant pump.
    All available at VWR scientific.
    Strangley enough standard black iron pipe works with concentrated sulfuric, forms a passive layer immune to further attack. Will not work with dilute solutons though.
