openhead

Openhead, or open-head, describes a type of industrial drum used for bulk storage and shipment of liquids and semi-solid materials. It is a steel drum with a detachable head, as opposed to a permanently welded top found on closed-head drums. The top is removed for direct access to the contents, and is typically secured with a locking ring or bolt ring. Open-head drums usually include large openings and threaded bungs for venting and dispensing, but the head is not permanently fixed.

Materials and sizes: They are commonly carbon steel, stainless steel, or lined variants for chemical compatibility. Common capacities are 30 and 55 gallons (about 120 and 210 liters). Interiors may be coated or lined with polymer to resist corrosion or contamination. They require specialized equipment for filling and emptying, and often need secondary containment.

Applications: Used in chemicals, paints, coatings, food ingredients, and pharmaceuticals where access to contents is needed for cleaning, sampling, or refilling. They are suitable for bulk storage on pallets and can be used in environments where direct content access is advantageous.

Standards and safety: Open-head drums are governed by packaging regulations and standards, including UN recommendations for drum packaging and national safety guidelines. Proper labeling, hazard communication, and handling procedures are essential to ensure safe transport, storage, and disposal.
