ʻO Hydrogen sulfide corrosion resistant pipeline steel i hoʻohana nui ʻia no ka hana ʻana a me ka lawe ʻana i ka pipeline kinoea ʻawaʻawa.Me ka hoʻomaikaʻi ʻana i ke kaomi lawe ʻana a hoʻemi i ke kinoea mai ka manaʻo o ke kumukūʻai o ka desulfurization, i kekahi manawa me ka ʻole o ka desulfurization o nā kūlana pipeline kinoea, no laila e hoʻohana nā pipeline i ke kūpaʻa ʻana o ka pipeline i ka hydrogen sulfide.
Hydrogen sulfide corrosion kila nopaipu ailaa ʻo ka pipeline kinoea ka mea paʻakikī loa e hana i kahi ʻano kila, no ka maʻemaʻe o ke kila hoʻoheheʻe ʻia, nā mana hoʻokaʻawale billet a me nā koi o ka ʻōwili a me ka hoʻoluʻu o nā kaʻina metallurgical kuʻuna kiʻekiʻe ʻaʻole hiki ke hoʻokō i nā koi.

ʻO ka maʻamau i loko o ke kaiapuni kinoea, ʻelua kumu hoʻoheheʻe pipeline: ʻo ka sulfide stress corrosion cracking, i kuhikuhi ʻia iā SSC.Aia ka hemahema ma ka ʻili kila ikaika a me ka ʻino o loko a me ka hydrogen sulfide corrosion ma lalo o ka hana a ka mea waena me ke kuhikuhi koʻikoʻi perpendicular wall māwae.I ka pipeline i ke kaʻina hana, ke kiʻekiʻe-grade kila pipeline prone i SSC.

ʻO kekahi o ka hydrogen induced cracking, i kuhikuhi ʻia iā HIC.ʻO nā māwae ma muli o ke kiʻekiʻe o ka hydrogen sulfide kinoea kinoea i loko o ka ʻino kila i loko o ka hydrogen i hana ʻia ma kahi kokoke i nā inclusions a me ka hoʻokaʻawale ʻana e hoʻonui ai i ka ʻili e like me ka nahā o ka pā.Loaʻa ka HIC ma ke kila haʻahaʻa, waena-ikaika i kanu ʻia.
