Ma ke kaʻina o ka mālama ʻana i ka aila a me ka lawe ʻana, ma muli o ke kiʻekiʻe o ka sulfur maʻiʻo i loko o ka ʻaila ʻaila, ua hōʻike ʻia ke kila maʻamau i ka ʻāina H2S pulu no ka manawa lōʻihi, kahi mea e pili ana i nā māwae hydrogen-induced a me ka hydrogen sulfide stress corrosion cracking, kanu i kahi pilikia palekana nui no ka hana palekana.
I ka pane ʻana i nā pilikia i luna, ua hoʻohana nui ʻia ke kila hydrogen-kūpono i ka petrochemical nui o ka home, ka mana wela, ka hale kiaʻi desulfurization a me nā papahana ʻē aʻe ma muli o kona kūpaʻa maikaʻi ʻana i ka haki ʻana i ka hydrogen-induced a me ka sulfide stress corrosion cracking.ʻO nā māka maʻamau ʻo 16MnR (HIC), Q345/Q355 (HIC), API 5L X52, ASTM A516 Gr.70 (HIC).
I kēia manawa, ua hoʻopau nā wili kila Kina i ka hana kūʻokoʻa o ke kila hydrogen-resistant, me ka kūleʻa o ka hoʻololi ʻana i nā huahana i lawe ʻia mai.Me ka hoʻomohala lohi ʻana o nā lako petrochemical nui, i mea e hoʻomaikaʻi ai i ka hana hana, pono koke ka mākeke i kahi mea hoʻoheheʻe kiʻekiʻe no ka hana wili.Ua hoʻokuʻu kā mākou hui i kahi uwea kuʻihao arc a me ka flux i hoʻohālikelike ʻia me ka metala kumu me ke kūpaʻa maikaʻi loa i ka haki ʻana i ka hydrogen-induced a me ka sulfide stress corrosion cracking.
ʻO nā waiwai kino a me nā kemika o ka hydrogen-resistant steel submerged arc welding wire GWL-W10KHMSHA me ka flux GXL-121 i hoʻomohala ʻia e kā mākou hui penei:
