摘要:
To provide a hydrogen sulfide mixture hardly corroding metals. The hydrogen sulfide mixture contains hydrogen sulfide and water. The hydrogen sulfide mixture is filled into a filling container so that at least one part of the hydrogen sulfide mixture is liquid and the moisture concentration of a gaseous phase is 0.001 mol ppm or more and less than 75 mol ppm.

An aluminum alloy material for a high-pressure hydrogen gas container contains 0.6 to 1.5 mass% of Si, 0.6 to 1.6 mass% of Mg, 0.1 to 1.0 mass% of Cu, 0.05 to 0.4 mass% of Fe, 0.9 mass% or less of Mn, 0.3 mass% or less of Cr, 0.15 mass% or less of Zr, 0.2 mass% or less of V, 0.25 mass% or less of Zn, and 0.1 mass% or less of Ti, with the balance consisting in Al and inevitable impurities. The total content of Mn, Cr, Zr, and V is 0.05 mass% or more. The material has a yield strength S (MPa) and an electrical conductivity E (IACS%) satisfying formulae (1) and (2). The material has a yield strength S of 270 MPa or more and an electrical conductivity of 36 IACS% or more. (1): S ≤ -10.46 x E + 801, (2): S ≥ -25 x E + 1296
摘要:
The present invention relates to a pressure vessel for containing or transporting pressurized gas. More particularly it relates to such vessels for containing or transporting compressed natural gas. The present invention also relates to a method of storing or transporting gas onshore or offshore. Moreover, the present invention relates to a vehicle for transporting gas, in particular compressed natural gas.

摘要:
An object of the present invention is to provide a 6000-series aluminum alloy material for a high-pressure gas container which has both of resistance to hydrogen embrittlement and mechanical properties. In the aluminum alloy material for a high-pressure gas container, the contents of Fe, Mn and Cu fall within narrower ranges than the standard composition of AA6066 alloy. The aluminum alloy material is produced to have a structure in which a predetermined amount of fine dispersed particles are dispersed therein and coarse crystallized materials are small, and therefore strength and resistance to hydrogen embrittlement are improved, which are required for a high-pressure gas container.
