Hydrochloric Acid Storage Tanks must be able to resist the highly corrosive nature of the chemical.
Hydrochloric Acid is a highly corrosive chemical and it emits fumes that can be fatal. The storage solution for Hydrochloric Acid must include a tank that can safely store the acid and a scrubber that can deal with the fumes. Fortunately, HDPE (High Density Polyethylene) has excellent chemical compatibility with Hydrochloric Acid solutions in 37% concentration. The safest approach is to use a double wall storage tank so you have built in containment of any leaks or spills from the primary tank.
Our Hydrochloric Acid tanks systems
incorporate sealed bolt-down manways to keep fumes from
escaping. Our HCL system also includes the use of
thermoplastic welded HDPE flanges and couplings rather than
screw-on or bolt-on fittings. Welded fittings eliminate
the need for gaskets.
Recommended Materials for Hydrochloric Acid 37% Tank
Systems
Listed below is our selection of Hydrochloric Acid Double Wall Polyethylene tanks with a rating of 1.9 specific gravity followed by our Single Wall Polyethylene tanks with a 1.9 SG rating. A double wall tank is strongly recommended since the sealed, built-in containment will not only capture spills but also will keep fumes from spilled acid contained as well.
