M'kati mwa kusungirako mafuta osakanizika ndi kunyamula, chifukwa cha kuchuluka kwa sulfure mumafuta osakanizika, chitsulo wamba chimawonekera ku chilengedwe chonyowa cha H2S kwa nthawi yayitali, chomwe chimakonda ming'alu ya hydrogen-induced ndi hydrogen sulfide stress corrosion, kukwirira a chiwopsezo chachikulu chachitetezo pakupanga kotetezeka.
Poyankha mavuto omwe ali pamwambawa, chitsulo chosagonjetsedwa ndi haidrojeni chakhala chikugwiritsidwa ntchito kwambiri m'magulu akuluakulu a petrochemical, mphamvu zotentha, nsanja ya desulfurization ndi ntchito zina chifukwa cha kukana bwino kwa hydrogen-induced cracking ndi sulfide stress corrosion cracking. Makalasi wamba ndi 16MnR (HIC), Q345/Q355 (HIC), API 5L X52, ASTM A516 Gr.70 (HIC).
Pakadali pano, mphero zazitsulo zaku China zamaliza kupanga paokha zitsulo zosagwira haidrojeni, ndikulowa m'malo mwazogulitsa kunja. Pakutukuka kwapang'onopang'ono kwa zida zazikulu za petrochemical, kuti zitheke kupanga bwino, msika umafunika mwachangu zida zowotcherera zopangira zowotcherera. Kampani yathu yakhazikitsa waya wowotcherera wa arc ndi flux womwe umafanana ndi chitsulo chokhazikika chomwe chimakana kusweka kwa hydrogen-induced and sulfide stress corrosion cracking.
Zomwe zimapangidwira komanso zopangidwa ndi chitsulo chosagwira ma hydrogen zitsulo zomizidwa ndi arc GWL-W10KHMSHA zokhala ndi flux GXL-121 zopangidwa ndi kampani yathu ndi motere:

Waya wowotcherera wa hydrogen-resistant arc GWL-W10KHMSHA wophatikizidwa ndi flux GXL-121 yopangidwa ndi kampani yathu ili ndi ntchito yabwino kwambiri yowotcherera. Kuchita kwa HIC ndi SSC kwadutsa kuwunika kwa gulu lachitatu. Zithunzi zowotcherera ndi malipoti oyendera zikuwonetsedwa pachithunzi pansipa:
