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.

Abstract: A vessel for the shipment of uranium hexafluoride includes a cylindrical wall closed by pair of approximately semi-ellipsoidal heads welded to form a sealed container. A service valve is located in one end. The valve is covered by a removable, watertight valve protection cover assembly. The vessel also includes a test port by means of which the integrity of the valve protection cover assembly may be tested after the cylinder has been filled with uranium hexafluoride and the valve protection assembly has been installed. The valve protection assembly is shaped so that it fits within the envelope of the standard 30B cylinders. The distal end of the valve protection assembly is recessed from a plane defined by the open end of the surrounding chime by at least one half inch, and preferably by ¾ inch or more. Accordingly, the fits within an overpack already approved by the NRC and used by shippers of uranium hexafluoride.

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 S.sub.U. The vessel has a cylindrical shell having an inside radius R.sub.I and a thickness T.sub.s which is less than that of prior art freight containers and substantially equal to: (P*R.sub.I)/(1/3S.sub.u -0.5 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.

Abstract: A container complying with ANSI.RTM. N14.1 for containing uranium hexafluoride (UF.sub.6) which minimizes entrapment of contaminants, thereby increasing the decontaminability of the container. The container includes a cylindrical shell welded to two cylinder heads wherein the weld inside the container provides a smooth transition between the heads and the shell while complying with ANSI.RTM. N14.1. The heads and the shell each have an annular land. A plasma weld fully penetrates the opposing lands to join the heads and the shell. No backup bar is used during the welding process.
