Pipeline corrosion resistance to hydrogen sulfide

Hydrogen sulfide corrosion resistant pipeline e sebelisoa haholo ho etsa le ho tsamaisa lipeipi tsa khase e bolila.Ka ntlafatso ea khatello ea phallo le ho fokotsa khase ho ea ka pono ea litšenyehelo tsa desulfurization, ka linako tse ling ntle le desulfurization ea maemo a lipeipi tsa khase, e le hore liphaephe tse joalo li tlameha ho sebelisa liphaephe tse hanyetsanang le kutu ho hydrogen sulfide.
Hydrogen sulfide corrosion resistant tšepe bakeng sapeipi ea olile phaephe ea khase ke eona e thata ka ho fetisisa ho hlahisa mofuta oa tšepe, ka lebaka la ho hloeka ha tšepe e entsoeng ka tšepe e qhibilihisitsoeng, li-taolo tsa khethollo ea billet le litlhoko tse laoloang tsa ho roala le ho pholisa tsa mekhoa e phahameng ea metallurgical e ke keng ea finyella litlhoko.

Hangata tikolohong ea khase ea asiti, mabaka a ho hloleha ha lipeipi ke a mabeli: e 'ngoe ke ho phatloha ha sulfide stress corrosion, ho buuoang ka SSC.The sekoli ke ka holimo matla tšepe holim 'me khatello ea kelello ka hare le hydrogen sulfide kutu tlas'a ketso ea seaplane hammoho le khatello ea maikutlo tataiso perpendicular lerako mapetsong.Ts'ebetsong ea ts'ebeletso, phaephe ea tšepe ea boemo bo holimo e tloaetseng ho SSC.

E 'ngoe ke ho phatloha ho bakoang ke haedrojene, ho boleloang ka HIC.The mapetsong a ka lebaka la e phahameng ea mahloriso ea hydrogen sulfide tikoloho ea khase ka corrosion tšepe ka hare ho haedrojene hlahisoang sebakeng se haufi le inclusions le karohano fella e ruisang holim'a bapileng le lerako petsoha.HIC e etsahala haholo-holo ka tšepe e tlase, e mahareng e lenngoeng.
