A method for making a cylinder for reactive gas mixtures in the calibration gas segment of the compressed gas market includes cutting a stainless steel tube to a desired length. First and second axial end portions of the cut tube are swaged. A spud is connected to the first swaged axial end portion of the cut tube. A base is connected to the second swaged axial end portion of the cut tube. The cylinder for reactive gas mixtures in the calibration gas segment of the compressed gas market includes a stainless steel tube having first and second swaged axial end portions and a central portion extending between the first and second swaged axial end portions. The spud is connected to the first swaged axial end portion of the tube. The base is connected to the second swaged axial end portion of the tube.

Provided a multi-layered pressurized gas container, for example one containing carbon dioxide for use in a device or system for the preparation of a carbonated drink, and processes for its manufacture.

The present disclosure provides an aluminum bottle and a preparation method thereof and belongs to the technical field of alloy. The present disclosure can improve the structure and enhance impact mechanical properties of an aluminum material by controlling a content of manganese to be 0.03-0.5 wt. %. Nickel can improve the strength and rust resistance of the aluminum material. Strontium can form an aluminum-strontium combination to adjust the crystal orientation of a metal lattice, improve forming, and greatly enhance the flexibility. Zirconium acts synergistically to improve the corrosion resistance of the aluminum material and improve surface gloss. The prepared aluminum material is light in weight and has the advantage of high bearing strength.

In the case of a method for the heat treatment of erected, preferably large-area tube wall regions or tube wall segments, in particular of a diaphragm wall, of a steam generator, in particular of a power plant, in the installed state, it is sought to provide a solution which permits the use of steel types which are more problematic with regard to power plant operation with elevated steam parameters, in particular the steels T23 and T24, in the erection of steam generators. This is achieved in that the tube wall regions or tube wall segments for heat treatment are subjected, in the installed state in the steam generator, and in particular over a large area, to a stress-relief annealing process.

The present invention is to provide a container capable of stably supporting an internal structure unit while effectively suppressing the occurrence of damage, and a method for manufacturing the container.

The container includes: a container main unit that includes a cylindrical base portion, dome portions that have a dome-like shape and are provided at both ends of the base portion, and a tubular first ferrule portion and a tubular second ferrule portion that have communicating holes formed at top portions of the respective dome portions to connect the inside and the outside, and are formed along the axis of the base portion; and an internal structure unit that is housed in the container main unit. The internal structure unit includes a free shaft portion provided on one end side along the axis of the base portion, and a fixed shaft portion provided on the other end side along the axis of the base portion. The free shaft portion is supported on the side of the first ferrule portion so as to be movable along the axis of the base portion. The fixed shaft portion is secured and supported in the communicating hole in the second ferrule portion via an engaging portion formed on the surface of the fixed shaft portion. At least part of the inner peripheral surface of the communicating hole in the second ferrule portion includes a plastically deformable portion to be engaged with the engaging portion.
