Hydrogen sulfide corrosion resistant pipeline steel feem ntau yog siv los tsim thiab thauj cov kav dej qaub.Nrog rau kev txhim kho ntawm kev xa khoom siab thiab txo cov pa roj los ntawm qhov kev xav ntawm tus nqi ntawm desulfurization, qee zaum tsis muaj desulfurization ntawm cov roj kav dej, yog li ntawd cov kav dej no yuav tsum tau siv cov kav dej corrosion tsis kam rau hydrogen sulfide.
Hydrogen sulfide corrosion resistant steel rauroj kav dejthiab cov raj xa hluav taws xob yog qhov nyuaj tshaj plaws los tsim ib hom hlau, vim nws cov purity ntawm molten steel, billet segregation tswj thiab tswj dov thiab txias qhov yuav tsum tau muaj cov txheej txheem metallurgical siab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.

Feem ntau nyob rau hauv ib puag ncig acid gas, pipeline tsis ua hauj lwm yog vim li cas yog ob: ib tug yog sulfide kev nyuaj siab corrosion cracking, xa mus rau SSC.Qhov tsis xws luag yog nyob rau hauv lub siab lub zog steel nto thiab cov kev ntxhov siab sab hauv thiab hydrogen sulfide corrosion nyob rau hauv qhov kev txiav txim ntawm qhov nruab nrab ua ke nrog kev ntxhov siab kev taw qhia perpendicular phab ntsa tawg.Nyob rau hauv cov raj xa dej hauv cov txheej txheem kev pabcuam, cov kav dej qib siab ua rau SSC.

Lwm qhov yog hydrogen induced cracking, xa mus rau HIC.Cov kab nrib pleb vim lub siab concentration ntawm hydrogen sulfide roj ib puag ncig rau hauv cov hlau corrosion hauv cov hydrogen uas tsim nyob rau hauv ib ncig ntawm inclusions thiab segregation uas ua rau enrichment ntawm cov nto thaum uas tig mus rau phab ntsa tawg.HIC feem ntau tshwm sim hauv qis-, nruab nrab-lub zog steel cog.
