I roto i te tukanga o te rokiroki hinu masivesivá me te kawe, na te nui o te whanariki i roto i te hinu masivesivá, ka kitea te maitai noa ki te taiao H2S maku mo te wa roa, e he e pängia ana ki te kapiti hauwai-induced me te hauwai sulfide ahotea te pakaruhanga waikura, tanumia he he morearea haumaru nui mo te hanga haumaru.
Hei whakautu ki nga raru o runga ake nei, kua whakamahia nuitia te rino hauwai-atete i roto i te petrochemical nui o te whare, te hiko waiariki, te pourewa desulfurization me etahi atu kaupapa na te pai o te atete ki te pakaru o te hauwai me te pakaru o te waikura sulfide. Ko nga tohu noa ko 16MnR (HIC), Q345/Q355 (HIC), API 5L X52, ASTM A516 Gr.70 (HIC).
I tenei wa, kua oti i nga mira tira Hainamana te hanga motuhake o te rino hauwai-atete, kua pai te whakakapi i nga hua kawemai. Na te tipu haere o nga taputapu petrochemical nui-nui, kia pai ake ai te mahi whakangao, me tino hiahia te maakete ki tetahi rawa whakangao pai mo te whakangao. Kua whakarewahia e to matou kamupene he waea pewa karekau me te rewharewha e rite ana ki te konganuku turanga me te tino atete ki te kapiti hauwai me te kowhatu whakapouri waikura.
Ko nga ahuatanga o te tinana me te matū o te rino hauwai-atete kua rukuhia te waea arc arc GWL-W10KHMSHA me te flux GXL-121 i whakawhanakehia e ta maatau kamupene e whai ake nei:
