Chitoliro chachitsulo chopanda msoko cha 20# nthawi zambiri chimagwiritsa ntchito chitsulo cha kaboni chapamwamba cha 20# ngati zopangira, chomwe ndi chitoliro chachitsulo chopanda msoko chapamwamba chomwe sichimatentha ndi kaboni chomwe chimagwiritsidwa ntchito kwambiri popanga nyumba ndi zomangamanga zamakanika.

Chitsulo cha 20# chili ndi makhalidwe awa: kusungunuka bwino komanso kusinthasintha kwamphamvu. Chifukwa cha mphamvu yake yochepa, ndi choyenera kukonzedwa mozizira komanso malo osakhala amphamvu kwambiri.

Chitoliro chachitsulo chopanda msoko cha 20# chingagwiritsidwe ntchito m'mafakitale otsatirawa:

1. Pa mapaipi a boiler okhala ndi mphamvu yochepa komanso yapakati, muyezo wogwiritsira ntchito ndiGB 3087, amagwiritsidwa ntchito popanga machubu a superheater ndi machubu a khoma oziziritsidwa ndi madzi a ma boiler apakati ndi otsika mphamvu (kuthamanga kogwira ntchito ≤5.9 MPa), omwe amakhala kutentha kwambiri (≤480℃) + malo ophikira nthunzi ya madzi kwa nthawi yayitali.

2. Mapaipi ophwanyira mafuta, muyezo wogwiritsira ntchito ndiGB 9948, yogwiritsidwa ntchito pa ma reactor, zosinthira kutentha, ndi zina zotero. za mayunitsi oyeretsera mafuta, zolumikizirana ndi acidic media (H₂S, CO₂) ndi kuthamanga kwambiri (mpaka 15 MPa)

3. Zipangizo za feteleza zothamanga kwambiri, muyezo wogwiritsira ntchito ndiGB 6479, yogwiritsidwa ntchito pa zida za feteleza zothamanga kwambiri (10~32 MPa) monga ammonia yopangidwa ndi urea, zomwe zimalumikizana ndi zinthu zowononga kwambiri (monga ammonia yamadzimadzi, urea melt)

Mapaipi achitsulo osapindika otentha othandizira ma hydraulic, muyezo wogwiritsira ntchito ndiGB/T17396, yomwe imagwiritsidwa ntchito popangira ma hydraulic support columns ndi ma jacks m'migodi ya malasha, ndipo imapirira katundu wosinthasintha wa pafupipafupi (50~100 MPa) komanso kugwedezeka kwa mphamvu
