I le faagasologa o le teuina o suauu mama ma felauaiga, ona o le maualuga o le sulfur i totonu o le suauu mama, o le uamea masani e faʻaalia i le siosiomaga H2S susu mo se taimi umi, lea e faigofie i le faʻafefe o le hydrogen ma le hydrogen sulfide stress corrosion cracking, tanumia a. tulaga lamatia tele mo le saogalemu mo le gaosiga saogalemu.
I le tali atu i faʻafitauli o loʻo taʻua i luga, ua faʻaaogaina lautele le uamea faʻafefeteina i totonu o le fale petrochemical tele, malosi vevela, olo desulfurization ma isi galuega faatino ona o lona tetee lelei i le taʻeina o le hydrogen ma le sulfide stress corrosion cracking.O togi masani o 16MnR (HIC), Q345/Q355 (HIC), API 5L X52, ASTM A516 Gr.70 (HIC).
I le taimi nei, ua maeʻa le gaosiga tutoʻatasi o fale gaosi oloa a Saina o le hydrogen-resistant steel, ma manuia ai le suia o oloa mai fafo.Faatasi ai ma le faasolosolo malie o le atinaʻeina o masini petrochemical tele, ina ia faʻaleleia atili le gaosiga o le gaosiga, e manaʻomia vave e le maketi se mea faʻapipiʻi maualuga mo le gaosiga o gaosiga.Ua fa'alauiloa e le matou kamupani se uaea u'amea fa'afefe ma fa'afefe e fetaui ma le u'amea fa'avae ma le lelei tele o le tete'e atu i le ta'e e mafua mai i le hydrogen ma le ta'e a le sulfide stress corrosion.
O mea fa'aletino ma vaila'au o le uaea u'amea fa'ato'a fa'afefeteina o le hydrogen GWL-W10KHMSHA fa'atasi ai ma le flux GXL-121 na atia'e e la matou kamupani e fa'apea:
