20 # chitsulo chosasunthika chitoliro nthawi zambiri chimagwiritsa ntchito 20 # zitsulo zapamwamba kwambiri za carbon monga zopangira, zomwe ndi chitoliro chapamwamba cha mpweya chosasunthika chachitsulo chomwe chimagwiritsidwa ntchito pomanga nyumba ndi makina.

20 # zitsulo ali ndi makhalidwe awa: plasticity wabwino ndi weldability amphamvu. Chifukwa cha mphamvu zake zochepa, ndizoyenera kuzizira kozizira komanso zochitika zopanda mphamvu.

20 # opanda zitsulo chitoliro angagwiritsidwe ntchito m'mafakitale zotsatirazi:

1. Kwa mapaipi opopera otsika ndi apakatikati, muyezo wokhazikitsidwa ndiMtengo wa GB3087, amagwiritsidwa ntchito popanga machubu a superheater ndi machubu oziziritsa pakhoma amadzi apakati komanso otsika kwambiri (kuthamanga kwa ≤5.9 MPa), komwe kumakhala kutentha kwambiri (≤480 ℃) + malo otulutsa mpweya wamadzi kwa nthawi yayitali.

2. Mafuta ophwanyidwa mapaipi, muyezo wa kukhazikitsa ndiMtengo wa 9948GB, yogwiritsidwa ntchito pazitsulo, zotenthetsera kutentha, ndi zina zotero za mafuta oyeretsera mafuta, kulumikizana ndi ma media acidic (H₂S, CO₂) ndi kuthamanga kwakukulu (mpaka 15 MPa)

3. Zida za feteleza zapamwamba kwambiri, muyezo wokhazikitsidwa ndiMtengo wa 6479GB, yogwiritsidwa ntchito pazida za feteleza zothamanga kwambiri (10 ~ 32 MPa) monga synthetic ammonia ndi urea, zomwe zimalumikizana ndi zinthu zowononga kwambiri (monga ammonia yamadzi, urea melt)

Mapaipi achitsulo osasunthika otentha opangira ma hydraulic, mulingo wokhazikitsidwa ndiGB/T17396, yogwiritsidwa ntchito ngati mizati yothandizira ma hydraulic ndi ma jacks m'migodi ya malasha, ndipo imapirira kusinthasintha kwapang'onopang'ono (50 ~ 100 MPa) ndi kugwedezeka kwamphamvu
