High-performance acid storage tanks designed for corrosive liquids. Leak-proof, compliant, and built to last with Shijiazhuang Enric Gas Equipment Co., Ltd.’s 50+ years of expertise.
Inferior materials degrade under sulfuric, hydrochloric, or nitric acid exposure, leading to costly spills and environmental hazards. According to the IEA’s Gas 2025 Report, improper storage accounts for 15% of industrial chemical accidents.
Failing to meet ASME, DOT, or CE standards results in fines, shutdowns, or lost contracts. Fortune Business Insights projects the industrial gases market to exceed $193B by 2034, with compliance as a top buyer requirement.
Poorly designed tanks require frequent repairs, increasing TCO (Total Cost of Ownership) by up to 40%. MIT’s Natural Gas Study highlights that substandard storage systems inflate operational expenses.
Off-the-shelf tanks often lack volume, pressure, or material adaptability for specialized acids (e.g., hydrofluoric acid), forcing compromises in safety or efficiency.
Relying on single-source suppliers leads to lead times of 6+ months. Enric’s integrated China supply chain cuts delivery to 8–12 weeks.

🔹 Note: For hydrofluoric acid, we recommend HDPE with antimony trioxide additive. For high-temperature acids, titanium-lined tanks are available.
Our acid storage tanks serve critical roles in:
Sulfuric acid (98%) storage for fertilizer production (e.g., phosphoric acid plants). Case: 10x EST-5000 tanks supplied to a Dow Chemical facility in Texas.
Ultra-pure hydrochloric acid (35%) for wafer etching. Case: 5x EST-1000 HDPE tanks for Intel’s Ohio fab.
Hydrofluoric acid alkylation units. Case: Custom titanium-lined EST-20000 for Shell’s Singapore refinery.
Nitric acid (68%) for pH adjustment. Case: 20x EST-500 tanks for a Veolia plant in France.
Phosphoric acid for lithium-ion cathode production. Case: 8x EST-2000 for CATL’s Germany plant.

Enric’s EST-5000 tanks at a fertilizer production site
Sulfuric Acid (98%): 316L SS + PTFE lining.
Hydrochloric Acid (35%): HDPE or 316L SS.
Nitric Acid (68%): 304L SS (with passivation) or titanium.
Hydrofluoric Acid (49%): HDPE with antimony trioxide.
Phosphoric Acid (85%): 316L SS or rubber-lined carbon steel.
FRP tanks are lighter and cheaper but have limited pressure ratings (≤50 psi) and shorter lifespans (10–15 years). Enric’s 316L SS tanks last 20+ years and handle up to 3000 psi. For high-pressure or high-purity applications, metal tanks are superior.
For stationary tanks: ASME Section VIII (pressure vessels) + UL 142 (flammable liquids, if applicable).
For transport: DOT 49 CFR (e.g., DOT 31HA1Y for corrosive liquids).
Enric’s tanks are pre-certified for both.
Yes! We offer full customization:
Standard models (in stock): 2–4 weeks.
Custom designs: 8–12 weeks (including engineering review).
Expedited shipping: Available for urgent orders (additional fee).
Tanks are shipped via 40’ HC containers (up to 4 units per container for EST-5000).
