摘要： 1,184,811. Hydrogen-resistant pressure vessel. MITSUBISHI TUKOGYO K.K. 14 Feb., 1967, No. 7120/67. Heading B1X. [Also in Division B3] In a laminated pressure vessel exposed interiorly or exteriorly to hydrogen at elevated temperature and pressure and having a circumferential weld extending through the wall of the vessel to join the laminations, at least the area of the weld exposed to hydrogen is an austenitic steel containing 16-30% chromium or a ferritic steel containing 10-30% chromium. A pressure container has an inner layer 21 of 0.5% molybdenum steel. The inner laminations 22 are of the same steel and the outer laminations 23 are of carbon steel or 0.2% molybdenum steel. The weld consists of an inner deposit 24 of 13% chromium steel and an outer deposit 25 of carbon steel or 0.2% molybdenum steel. A vent 26 is prevents gas pressure developing between the laminations. In a modification, the deposit 25 and the laminations are of carbon steel and the inner deposit is of 18/8 stainless steel. Where the inner layer 21 is thick, the depth of the inner deposit 24 may be less than such thickness. The weld may be homogeneous. In a further modification, the inner layer 21 is of carbon steel clad with 18/8 stainless steel.

摘要： 1,182,142. Pressure vessel. MITSUBISHI JUKOGYO K.K. 14 Feb., 1967, No. 7119/67. Heading B1X. [Also in Division B3] In a laminated pressure vessel in which each lamination consists of one or more plates joined by seam welds, the inner or outer lamination is formed of hydrogen resistant steel and the weld(s) of the adjacent lamination is maintained out of contact with the hydrogen resistant steel by interposition of a backing strip. The weld 3 is backed by a steel strip 20 contacting the inner hydrogen resistant lamination 1. The other laminations are not hydrogen resistant. A gas passage 16 extends through the wall of the vessel to the inner lamination 1. The strip 20 and the passage 16 minimise hydrogen contamination of the laminations 12 ... 16.

摘要： Welding-seam chamfers of a multi-wall container consist of a Cr-Mo steel containing 1-6% Cr and 0.3-1.3% Mo or of a Mo steel containing 0.3-0.7% Mo, and are coated with a built-up welded layer (3) of Cr-Mo steel, resistant to embrittlement by H2, and not hardening through welding heat and containing 4-7 times Ti content or 8-14 times Nb content, calcd. on C content, or having a Ti-Nb content corresponding to eqn. Nb + 2Ti = (8-14) x C. The container parts are then subjected to a standardisation annealing. The welding seam part situated within internal cylinder (1) range is welded with a material similar to layer (3) or austenitic stainless steel in thickness equal to at least the thickness of internal cylinder (1), (the filler layer 4), and the remaining part of the welding seam is welded with a metal hardening only just below welding heat (filler layers 5).
