Abstract

A container for transporting and storing hazardous materials such as Chlorine includes a cylindrical body having end caps. The end caps are welded to the body to form a pressure vessel. The end caps have a peripheral edge that is recessed with respect to the ends of the body to protect the weld against damage from impact. The configuration of the juxtaposed components forms a lap joint that can be affixed together by a fillet weld.
