Title (EN) RING REINFORCEMENT FOR CONVENTIONAL DRUM
(FR) RENFORCEMENT ANNULAIRE POUR TONNEAU CLASSIQUE
Abstract:
(EN) 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.
(FR) On utilise un renforcement annulaire sur le sommet (H) et sur la base (B) circulaires d'un tonneau classique (D) de 55 gal.. Ce tonneau classique (D) contient un corps cylindrique (C) en acier dont les deux nervures en V classiques s'étendent vers l'intérieur des parois latérales au milieu du cylindre. Ce tonneau, que son sommet soit ouvert ou fermé, selon son type, possède un sommet (H) et une base (B) circulaires fermant l'intérieur du tonneau et scellés à ce dernier. On renforce ce sommet (H) et cette base (B) circulaires par soudage d'un cercle (R), ce qui empêche le tonneau de bomber et permet de le transporter avec un contenu, dont la pression s'exerçant sur l'extérieur du tonneau est de 25 psi maximum, sans déformation préjudiciable.
