Ensuring Safety, Compliance, and Reliability
Acid storage tanks are mission-critical for power generation, water treatment, chemical processing, and manufacturing. As tanks age, corrosion, UV exposure, and mechanical stress can compromise integrity. When repairs no longer mitigate risk, a well-planned acid tank replacement protects your people, equipment, and the environment—while improving reliability and lowering total cost of ownership.
Serving industrial facilities across Arizona.
When Replacement Is the Right Choice
Replace an acid tank if you’re seeing any of the following:
-
Recurrent leaks, weeping fittings, or soft spots in the shell or floor
-
Blistering/holiday failures in linings or coatings
-
Documented wall-thickness loss, cracking, or out-of-round conditions
-
Increasing maintenance frequency or unplanned downtime
-
Regulatory non-conformances or end-of-life findings from inspections
Timely replacement helps avoid environmental releases, production stoppages, and penalties—while bringing your system back into compliance and extending service life.
Materials & Design Options (by Chemical)
Selecting the right construction and lining system is key to performance:
-
Hydrochloric Acid (HCl): Commonly FRP (fiber-reinforced plastic) with suitable resin system; HDPE/XLPE for certain concentrations and temperatures.
-
Sulfuric Acid (H₂SO₄): Carbon steel or alloy tanks depending on concentration and temperature; rubber-lined or PTFE-lined options for enhanced corrosion resistance.
-
Phosphoric Acid (H₃PO₄): Stainless steel, FRP, or lined carbon steel based on process conditions.
Smart upgrades to consider:
-
Double-containment or engineered secondary containment
-
Leak detection sensors and continuous level monitoring
-
Proper venting, scrubbers, and emergency relief provisions
-
High-performance linings/coatings matched to chemical and temperature
-
Seismic anchoring and wind-load design suitable for Arizona conditions

FAQs
How do I know whether to repair or replace an acid tank?
If wall loss, cracking, or lining failures recur despite repairs—or inspections flag structural concerns—replacement typically offers lower lifecycle risk and cost than continued patching.
Which material is best for sulfuric acid tanks?
It depends on concentration and temperature. Many applications use carbon steel; others require alloys or rubber/PTFE-lined tanks. We specify materials based on your exact process conditions.
Can you replace a tank without significant downtime?
Yes. With temporary storage and phased tie-ins, we minimize outages. Your plan will include a detailed schedule, bypass options, and commissioning steps.
What compliance documentation do you provide?
We deliver drawings, material certifications, inspection and test records, coating/lining QA, and commissioning reports to support your environmental, safety, and quality requirements.
Do you offer secondary containment and leak detection?
Absolutely. We can add engineered containment, leak sensors, level monitoring, and alarms to improve safety and ease regulatory compliance.
