I-Hydrogen sulfide corrosion resistant corrosion steel esetshenziswa kakhulu ukukhiqiza nokuthutha ipayipi legesi emuncu.Ngokuthuthukiswa kwengcindezi yokulethwa kanye nokunciphisa igesi ngokombono wezindleko ze-desulfurization, ngezinye izikhathi ngaphandle kokususwa kwe-desulfurization yezimo zepayipi legesi, ukuze amapayipi anjalo asebenzise ukumelana nokugqwala kwepayipi ku-hydrogen sulfide.
I-Hydrogen sulfide corrosion resistant steel foripayipi likawoyelafuthi ipayipi legesi linzima kakhulu ukukhiqiza uhlobo lwensimbi, ngenxa yokuhlanzeka kwayo kwensimbi encibilikisiwe, izilawuli zokuhlukaniswa kwe-billet kanye nezidingo ezilawulwayo zokugoqa nokupholisa zezinqubo zensimbi zendabuko eziphezulu azikwazi ukuhlangabezana nezidingo.

Imvamisa endaweni yegesi ene-asidi, izizathu zokuhluleka kwepayipi zimbili: enye ukuqhekeka kokugqwala kwe-sulfide, okubhekiselwa ku-SSC.Isici sisendaweni yensimbi enamandla aphezulu kanye nengcindezi yangaphakathi kanye nokugqwala kwe-hydrogen sulfide ngaphansi kwesenzo se-medium kanye nokuqhekeka kodonga lwe-stress direction perpendicular.Emgqeni wenqubo yesevisi, ipayipi lensimbi lezinga eliphezulu elithambekele ku-SSC.

Okunye ukuqhekeka okwenziwe nge-hydrogen, okubhekiselwa ku-HIC.Imifantu ngenxa yokugcwala okuphezulu kwemvelo yegesi ye-hydrogen sulfide ekugqwaleni kwensimbi ngaphakathi kwe-hydrogen ekhiqizwa endaweni ehlanganisiwe kanye nokuhlukaniswa okuholela ekuthuthukisweni kobuso obuhambisana nokuqhekeka kodonga.I-HIC yenzeka kakhulu ensimbi etshalwe phansi, naphakathi nendawo.
