oljetønde

An oljetønde, or oil drum, is a cylindrical container used for storing and transporting oil, lubricants, fuels and related liquids. Most are made of steel or high-density polyethylene (HDPE). Typical capacities include 200 liters (about 55 US gallons), while smaller drums of 30 or 60 liters are also common. Steel drums are often used for heavier or more flammable liquids, while plastic drums are favored for chemicals that may corrode metal or for lighter-weight handling.

There are two main drum types: open-head and closed-head. Open-head drums have a removable lid and are typically used for liquids that are accessed directly, whereas closed-head drums are sealed at both ends and have bung openings on the top for filling and venting. Steel drums may feature two bung openings of different sizes to facilitate filling, venting and dispensing. Materials are chosen for chemical compatibility and durability, and drums intended for hazardous materials may be UN-certified for transport (for example, steel drums designed to meet UN packaging standards).

Handling and safety considerations include storing drums upright in well-ventilated areas away from heat, sparks and open flames. Secondary containment is recommended to contain leaks. When transferring liquids, proper grounding and bonding reduce static discharge. Drums should be clearly labeled with contents and hazards, and compatible equipment should be used to prevent spills.

End-of-life and reuse options vary by material. Metal and plastic oljetønde can be cleaned, inspected and reconditioned for reuse, or recycled. Used oil drums require proper management to prevent soil and water contamination and should comply with local environmental and transportation regulations.
