Enqubweni yokugcinwa nokuthutha uwoyela ongahluziwe, ngenxa yokuqukethwe okuphezulu kwesibabule kuwoyela ongahluziwe, insimbi evamile ibonakala endaweni emanzi ye-H2S isikhathi eside, ethambekele ekubeni nemifantu eyenziwe yi-hydrogen sulfide nokugqwala kokugqwala kwengcindezi, kungcwatshwe ingozi enkulu yokuphepha yokukhiqiza okuphephile.
Ukuphendula lezi zinkinga ezingenhla, insimbi engamelana ne-hydrogen iye yasetshenziswa kabanzi ku-petrochemical yasekhaya enkulu, amandla ashisayo, umbhoshongo we-desulfurization namanye amaphrojekthi ngenxa yokumelana kwayo kahle nokuqhekeka kwe-hydrogen-induced and sulfide stress corrosion cracking. Amabanga avamile angu-16MnR (HIC), Q345/Q355 (HIC), API 5L X52, ASTM A516 Gr.70 (HIC).
Njengamanje, izigayo zensimbi zaseShayina seziqedile ukukhiqiza okuzimele kwensimbi engamelana ne-hydrogen, ngokuphumelela esikhundleni semikhiqizo engenisiwe. Ngokuthuthuka kancane kancane kwemishini emikhulu ye-petrochemical, ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza, imakethe idinga ngokushesha izinto zokushisela ezisebenza kahle kakhulu zokukhiqiza ukushisela. Inkampani yethu yethule i-arc welding wire kanye ne-flux engaphansi kwamanzi ehambisana nesisekelo sensimbi ekwazi ukumelana kahle nokuqhekeka okubangelwa yi-hydrogen kanye nokuqhekeka kokugqwala kwe-sulfide stress.
Izici ezingokoqobo nezamakhemikhali zensimbi engazweli i-hydrogen engaphansi kwe-arc welding wire GWL-W10KHMSHA ene-flux GXL-121 eyakhiwe inkampani yethu imi kanje:

I-hydrogen-resistant steel arc welding wire i-GWL-W10KHMSHA ehlanganiswe ne-flux GXL-121 ethuthukiswe inkampani yethu inokusebenza okuhle kakhulu kokushisela. Ukusebenza kwe-HIC ne-SSC kuphumelele ukuhlolwa komuntu wesithathu. Izithombe zokushisela kanye nemibiko yokuhlolwa kukhonjisiwe esithombeni esingezansi:
Scrubber
Isithombe sokusebenza kwe-welding ku-groove
I-Ningbo Honest Metal Materials Co., Ltd. Izinto zokushisela zensimbi ezingamelana ne-Hydrogen zihlanganisa i-metal powder cored wire, i-electrode yesandla, nocingo oluqinile, olunohlu oluphelele nokusebenza okuhle kakhulu, olungasetshenziswa ngezindlela zokushisela ezihlukene nangaphansi kwezimo ezihlukahlukene zokusebenza. Siyakwamukela ukuthenga.
