The present disclosure relates to a metal material for a container for storing high-purity hydrogen fluoride, and to a manufacturing method therefor. Specifically, the disclosure relates to a metal material for a container for storing high-purity hydrogen fluoride, and a manufacturing method therefor. The metal material includes a graphite layer on the surface of a metal substance, and nickel fluoride films formed in structural defect spaces within the graphite layer, so that corrosion resistance and scratch resistance are improved, and thus high-purity hydrogen fluoride, which is a corrosive gas, can be stored and transferred without being contaminated.

A method for manufacturing a gas filling container is provided. The method includes performing a treatment of bringing an amine compound into contact with the inner surface of a gas filling container having at least the inner surface made of stainless steel, manganese steel, carbon steel, or chromium molybdenum steel, and, after the treatment, a treatment of volatilizing off the amine compound from the gas filling container.

A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.

The invention relates to a tank comprising a container with an opening and a cover, a flexible casing lying against the interior and exterior of the container. This allows increased resistance to the penetration of sharp objects, liquid and gaseous gases can be used interchangeably and various gas types with a fossil-type and biological-type consistency can be mixed and also heated and cooled in the tank. The invention relates to tanks (1) and staged tanks of the preceding claims, characterized in that in addition to LNG, said tanks can store biological methane gas.

A hydrogen pressure vessel capable of preventing hydrogen-induced cracking of a cylinder is provided. In a hydrogen pressure vessel according to one embodiment, a gap part (G) in which an inner peripheral surface of a cylinder (10) is spaced apart from an outer peripheral surface of a lid (20) is provided between a female thread part (10a) of the cylinder (10) into which the lid (20) is screwed, and a resin seal member (30), and the cylinder (10) includes a first through hole (41) for discharging gas in the gap part (G) into a relief pipe (51) and a second through hole (42) for introducing gas containing oxygen into the gap part (G) formed therein.

Cladding of the interior of a component part of a pressure vessel is shown. A lining which conforms to at least a portion of the interior geometry of the component is positioned in the interior of the component. The lining is then pressed into the component past its yield strength. The lining is then fused to the component.
