Tsawg- alloy siab- lub zog steel yog tam sim no cov khoom siv dav tshaj plaws hauv cov cuab yeej petrochemical.
- Cov laj thawj tseem ceeb: Tsawg- alloy siab- lub zog hlau ua tau raws li cov khoom siv dav dav ntawm cov khoom siv petrochemical:
- Kev Ua Haujlwm Zoo: Tsuas yog me me ntawm cov ntsiab lus alloying (xws li Mn, Si, Cr, thiab lwm yam), nws txhim kho lub zog thiab kev tiv thaiv corrosion thaum khaws cov khoom siv zoo thiab kev sib txuas ntawm cov hlau, ua kom tau raws li cov kev xav tau ntawm cov khoom siv petrochemical feem ntau xws li cov hlab ntsha siab, cov tso tsheb hlau luam, cov kav dej, thiab cov yees;
- Tus nqi tswj tau: Piv nrog cov hlau tsis muaj steel thiab cov alloys tshwj xeeb, nws yog tus nqi qis dua thiab pheej yig dua, ua rau nws haum rau cov ntawv loj -.
Kev txwv tsis pub siv lwm yam ntaub ntawv:
- Stainless hlau: Zoo heev corrosion kuj tab sis tus nqi siab; tsuas yog siv nyob rau hauv tshwj xeeb scenarios nrog heev corrosive xov xwm xws li sulfur thiab chlorine, txwv nws applicability.
- Thaum tshav kub kub-cov hlau tsis muaj zog: Tsuas yog rau qhov tshwj xeeb siab- qhov kub thiab txias (xws li pyrolysis rauv tube); ib qho xwm txheej- cov khoom siv tshwj xeeb, tsis siv rau hauv cov khoom siv dav dav.
- High- zoo carbon steel: Tsis muaj zog thiab corrosion kuj, ua rau nws nyuaj rau hloov mus rau complex high- siab thiab corrosive tej yam kev mob ntawm petrochemical khoom; nws daim ntawv thov ntau yog maj mam shrinking.
