RING REINFORCEMENT FOR CONVENTIONAL DRUM

摘要

A ring reinforcement is utilized on the circular head (H) and bottom (B) of a conventional 55 gallon drum (D). The conventional drum (D) contains a cylindrical steel body (C) having the two conventional V-shaped ribs expanded into the sidewalls at the middle of the cylinder. The drum, when either of the open-head or closed-head variety, has a circular head (H) and a circular bottom (B) closing in sealed relationship with the drum interior. This circular head (H) and circular bottom (B) are reinforced by welding a drum-reinforcing rim (R) preferably inside bulging results, enabling the barrel to be shipped with product with up to 25 psi pressure to the barrel exterior without objectional distortion.
