Purchasing managers in the energy, chemicals, and industrial gas sectors face recurring challenges when sourcing API storage tanks fabrication. Here’s what keeps them up at night:
API 620, API 650, ASME, DOT, CE, and PED—navigating these regulations is a minefield. A single oversight can lead to:
Source: Global Hydrogen Review 2025 (IEA) highlights the growing demand for compliant storage solutions in hydrogen and natural gas sectors.
With 90% of high-pressure gas storage tanks manufactured in Asia (per MarketsandMarkets 2025), buyers face:
Cheap upfront pricing often hides:
According to the MIT Future of Natural Gas Study, unplanned downtime in gas storage can cost operators $1M+ per incident.
Your solution? A single-source supplier with end-to-end compliance, transparent pricing, and proven reliability.

Our API storage tanks are deployed in 40+ countries across natural gas, hydrogen, electronics, and chemicals. Here’s how we solve critical challenges:
Client: Clean Energy Systems (California, USA)
Challenge: Needed API 620-compliant hydrogen storage for a 5,000 kg/day refueling station with fast-fill capability (350–700 bar).
Solution: ET-H2-3000 tanks with SA-387 Gr. 22 steel, hydrogen-embrittlement resistant, and ASME Section VIII Division 1 certification.
Result:
“Enric’s tanks outperformed European alternatives at 30% lower cost with no compromise on safety.” – John M., Operations Director, Clean Energy Systems
Client: Nigerian National Petroleum Corporation (NNPC)
Challenge: Required cryogenic API 650 tanks for LNG storage in a high-humidity, saltwater environment.
Solution: ET-CRYO tanks with 9% Ni steel, vacuum-jacketed insulation, and epoxy coating.
Result:
Client: Samsung Electronics (Pyeongtaek)
Challenge: Needed ultra-high-purity nitrogen storage for semiconductor fabrication with <1 ppm impurity tolerance.
Solution: ET-650-H tanks with electropolished interiors and specialty gas-grade certification.
Result:
API 620 covers low-pressure storage tanks (typically <15 psi), used for atmospheric or low-pressure gases like LNG, butane, or propane.
API 650 governs welded steel tanks for oil storage (typically 2.5 psi to 15 psi), but can be adapted for higher-pressure gas applications with additional reinforcement.
For high-pressure gases (e.g., hydrogen, CO2, or compressed natural gas), ASME Section VIII is often required in addition to API standards.

★★★★★ “We ordered 10 ET-H2-3000 tanks for our California hydrogen station. Enric delivered on time, on budget, and the tanks have zero leaks after 2 years. Their H2-resistant steel outperformed European competitors at 30% lower cost. Highly recommend.”
★★★★★ “Enric’s ET-CRYO tanks for our LNG terminal withstood Nigeria’s humid, salty climate with no corrosion. Their vacuum insulation reduced BOG by 40%, saving us $200K/year in gas losses. Best decision we made.”
★★★★★ “We needed ultra-high-purity nitrogen storage for our semiconductor fab. Enric’s ET-650-H tanks maintained 99.9995% purity with zero downtime in 2 years. Their electropolished interiors were key. 5-star service.”
★★★★★ “As a European buyer, we were skeptical about Chinese quality. But Enric’s PED-certified tanks passed TÜV inspection on first try. Their ASME + API 620 compliance gave us confidence. Delivery was 30% faster than local suppliers.”
★★★★★ “Enric’s API 650 tanks for our offshore platform exceeded expectations. The 3-layer epoxy coating and cathodic protection held up in saltwater exposure. No maintenance issues in 18 months.”
