Ring reinforcement for conventional drum |
摘要 |
A ring reinforcement is utilized on the circular head and bottom of a conventional 55 gallon drum. The conventional drum contains a cylindrical steel body 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 and a circular bottom closing in sealed relationship with the drum interior. This circular head and circular bottom are reinforced by welding a drum-reinforcing rim preferably inside the barrel. It has been found that remarkable resistance to bulging results, enabling the barrel to be shipped with product with up to 25 psi pressure relative to the barrel exterior without objectional distortion.
