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.

Abstract: A freight container for transporting a pressurized fluid at a design pressure P, including a tank and mounted within an ISO frame. The tank includes a vessel formed of a material having an ultimate tensile strength SU. The vessel has a cylindrical shell having an inside radius RI and a thickness Ts which is less than that of prior art freight containers and substantially equal to: (P*Ri)/((Su/Xa)?(Xb*P)). Such a vessel conforms to ASME Boiler and Pressure Vessel Code, Section VIII, Division 2. The freight container may be mounted on a transport vehicle, before or after being filled with the pressurized fluid, and transported to a remote location.
