These lidded drums (photo) are dull TIG (tungsten-inert gas) welded with welding filler material and without gaps. The seams are rolled flat and finely polished inside and out. The drums are also easy to clean and residue-free, and have a high stability, even at maximum load. They are available in volumes from 0.5 to 300 L, and in different diameters. The surfaces are polished or electro-polished for optimum product output with roughness less than 0.25 μm. Sealing materials include silicone, EPDM, Viton, and FEP-coated (fluorinated ethylene propylene) seals with FDA approval. In addition to the industry-standard materials, the company now also offers drums for extreme conditions in Hastelloy 2.4602/C 22 nickel alloy, which is highly corrosion resistant to acids and chlorine dioxide. — Bolz Intec GmbH, Argenbühl-Eisenharz, Germany
