While stainless steel drums are currently used for contents needing ultra-clean surface protection, the conventional method of roll-seaming the top and bottom heads to the body results in a small interior crevice which, with reuse, can accumulate unwanted bacteria. With a Seamless Sanitary drum, there is no interior crevice, in fact, the vertical wall of the steel meets the raised sidewall of the bottom head with a welded bead that is smooth. The result is a bottom and top that is fully curved and crevice free (see illustration). These drums can be used for processing of SuperClean contents or for safe transport of the most aggressive chemicals including Nitric acid. Available in Open Head and Closed Head styles, or as a Processing Drum, these drums are constructed of all 1.5mm (16 gauge) 304 stainless steel with a 2B finish with top and bottom foot rings that are exterior welded in place. The optional features include two protective “roll bars” fitted into the side rolling hoops, and tight heads have the option of machined or drop forged 2″ and ¾” plugs in the top head.
These drums are also UN certified for dangerous goods in both an Open Head and Closed Head style. This is a very heavyweight and impressive packaging!
