Öltanks

Öltanks are containers designed to store oil and other petroleum liquids for energy, manufacturing, and transportation uses. They are employed across residential, commercial, and industrial settings and can be located above ground or underground. Sizes range from a few hundred liters in home heating systems to many thousands of cubic meters in refineries and terminals. Common materials include carbon steel, stainless steel, and fiberglass-reinforced polymers. Above-ground tanks may have fixed roofs or floating roofs to reduce evaporation, while underground tanks are typically built to resist corrosion and include leak detection features.

Construction and design aspects vary by application. Steel tanks are usually cylindrical with welded seams and may include internal linings or coatings to resist oil degradation and corrosion. Fittings such as fill pipes, vents, gauges, and access hatches are integrated for operation and monitoring. Safety features often comprise overflow and venting systems, secondary containment, corrosion protection (such as cathodic protection for steel tanks), and leak detection arrangements. In many regions, environmental and fire-safety standards apply to both above-ground and underground storage.

Standards and regulation commonly address integrity, containment, and environmental protection. Notable frameworks include API 650 for welded steel storage tanks, EN 14015 in Europe, and NFPA 30 for flammable liquids, alongside local environmental codes governing spill prevention, leak detection, and proper decommissioning of tanks.

Maintenance and risk management emphasize regular inspections, corrosion monitoring, tightness testing, and prompt remediation of any leaks or structural damage. Proper design, installation, operation, and end-of-life management are essential to minimize soil and groundwater contamination and to ensure safe storage of oil.
