ASTM A302 Papa A Mn-Mo Alloy Pressure Vessel Steel Plate

Hoʻopili kēia kikoʻī i nā papa kila manganese-molybdenum a me manganese-molybdenum-nickel i manaʻo nui ʻia no nā paila welded a me nā moku kaomi ʻē aʻe. ʻO ASTM A302 kahi ʻano haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e uhi ana i 4 mau māka like ʻole (A, B, C, D), ʻo ka papa C a me D ka haku mele Ni, me ka mānoanoa like, ka hua a me ka ikaika tensile o ka Papa C ka like o ka Papa B, ʻoiai ʻoi aku ka kiʻekiʻe o ka elongation rate o ka papa C. Ua uhi kēia kikoʻī i ka manganese-molybdenum a me ka manganese-molybdenum-nickel alloy plates i manaʻo ʻia no nā boiler welded a me nā moku kaomi ʻē aʻe. ʻO ASTM A302 kahi ʻano haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e uhi ana i 4 mau māka like ʻole (A, B, C, D), ʻo ka papa C a me D ka haku mele Ni, me ka mānoanoa like, ka hua a me ka ikaika tensile o ka Papa C ka like o ka Papa B, ʻoiai ʻoi aku ka kiʻekiʻe o ka elongation rate o ka papa C. Hana ʻia ia no ka Pressure Vessel, Boiler, Storage Tanks and Heat Exchanger in Oil, Gas Project.
