Kukana kwa dzimbiri kwa mapaipi ku hydrogen sulfide

Hydrogen sulfide corrosion resistant pipeline zitsulo zomwe zimagwiritsidwa ntchito popanga ndi kunyamula mapaipi a gasi wowawasa.Ndi kusintha kwa mphamvu yobereka ndi kuchepetsa gasi kuona mtengo wa desulfurization, nthawi zina popanda desulfurization wa zinthu mapaipi mpweya, kotero kuti mapaipi ntchito dzimbiri kukana dzimbiri hydrogen sulfide.
Hydrogen sulfide corrosion resistant steel fornjira ya mafutandi payipi mpweya ndi zovuta kwambiri kutulutsa mtundu wa zitsulo, chifukwa cha chiyero cha chitsulo chosungunula, amazilamulira billet tsankho ndi ankalamulira anagubuduza ndi kuziziritsa zofunika njira mkulu miyambo zitsulo sangathe kukwaniritsa zofunika .

Nthawi zambiri m'malo a mpweya wa asidi, zifukwa zolephera za mapaipi zimakhala ziwiri: imodzi ndi sulfide stress corrosion corrosion cracking, yotchedwa SSC.Chilema ndi mkulu mphamvu zitsulo pamwamba ndi maganizo mkati ndi hydrogen sulfide dzimbiri pansi zochita za sing'anga pamodzi ndi maganizo malangizo perpendicular khoma ming'alu.M'mapaipi muutumiki, mapaipi achitsulo apamwamba kwambiri omwe amakonda ku SSC.

Chinanso ndi kusweka kopangidwa ndi haidrojeni, komwe kumatchedwa HIC.The ming'alu chifukwa mkulu ndende ya hydrogen sulfide mpweya chilengedwe mu dzimbiri zitsulo mkati haidrojeni opangidwa kufupi ndi inclusions ndi tsankho chifukwa kulemeretsa padziko kufanana ndi khoma akulimbana.HIC imapezeka makamaka muzitsulo zotsika, zapakati-zamphamvu zobzalidwa.
