An LNG tank is a single-shell LNG tank having one shell and at least one pipe extending from the LNG tank to a tank connection space of the LNG tank. The shell of the LNG tank is substantially surrounded by insulation. The LNG tank has at least one bellow connection surrounding at least part of the length of the at least one pipe for connecting the at least one pipe extending from the LNG tank to the tank connection space. A system for connecting at least one pipe between an LNG tank and a tank connection space thereof is also provided. At least one pipe extends from the LNG tank to the tank connection space and which LNG tank is a single-shell tank having one shell. The at least one pipe is connected between the LNG tank and the tank connection space by at least one bellow connection.

A cryogenic tank arrangement includes a tank body enclosing a storage space for storing liquefied gas. The tank arrangement has a safety valve arrangement in which at least one pressure relief valve is directly connected to the storage space of the tank body. There is a pressure relief valve arranged directly connected to at least two locations on a same face of the tank body.

A gas pressure container for an airbag system of a motor vehicle is disclosed having a tube element with a high bursting resistance when internal pressure is being applied. The tube element includes a steel alloy and a first longitudinal portion of the tube element has a tensile strength Rm,.sub.11 higher than (>) 800 MPa, a transition temperature Tu,.sub.11 of at least −40° C., and an outer circumference U1. The tube element also includes at least one second longitudinal portion and/or additional longitudinal portions, which extend axially from the first longitudinal portion. The second longitudinal portion or the additional longitudinal portions and the first longitudinal portion are formed from a seamless or welded single-piece tube made of a uniform material, and more specifically from a hot-rolled or cold-drawn tube.

Provided is a pressure vessel having an outer layer with an improved gas barrier property, a lightweight liner with an excellent gas barrier property, and a novel method for manufacturing a pressure vessel. The pressure vessel contains a liner and an outer layer of the liner, wherein the outer layer is configured by a composite material that contains a continuous fiber and a polyamide resin impregnated into the continuous fiber; the polyamide resin contains a structural unit derived from diamine and a structural unit derived from dicarboxylic acid; and 50 mol % or more of the structural unit derived from diamine is derived from xylylenediamine.

Novel cylinder passivation procedures to increase the room temperature stability of gaseous tin deuteride (SnD.sub.4) are described. Incorporation of specific organic-containing materials, which when applied onto surfaces of a vessel and/or conduit extending therefrom, can increase the shelf life stability of thermodynamically unstable gases stored within such pretreated vessels.
