Handling Acids Sulfuric Acid (H2SO4) - Most piping systems cannot handle all concentrations of sulfuric acid. Mild steel, stainless, alloys, plastic, fiber-reinforced plastic, glass and graphite all have something to offer but many have limitations. Hydrochloric Acid (HCl) is a highly corrosive solution which plays a prominent role in the production of chemicals, petroleum, metals, textiles, leather and food products. Aqueous Hydrofluoric Acid (HF) is used to dissolve ores, clean stone and brick, acidize oil wells, electropolish metals, etc. It is also used as an alternate source of fluorine for aluminum production. Anhydrous Hydrogen Fluoride (HF) is a fluorinating agent in organic and inorganic reactions, and a catalyst in alkylation, isomerization, condensation, dehydration and polymerization reactions. Hydrobromic Acid (HBr) is used in the preparation of various chemical intermediates, synthetic dyes, drugs, perfumes, bromides and in photography. Anhydrous Hydrogen Bromide is used in the preparation of organic bromides and as a catalyst in the controlled oxidation of organic materials and the alkylation and cracking of petroleum products. Anhydrous Hydrogen Iodide and Hydriodic Acid (HI) is used in the preparation of iodine salts, pharmaceuticals, and as a disinfectant.
