Tanthauzo:chitoliro chachitsulo chotentha kwambirindi wapakatikatichitsulo chomangira mpweyaMapaipi achitsulo ozizira, otentha komanso otentha kwambiri ali ndi magwiridwe antchito abwino, makina abwino, mtengo wotsika komanso magwero ambiri, kotero amagwiritsidwa ntchito kwambiri. Chofooka chake chachikulu ndichakuti zida zogwirira ntchito zomwe sizimalimba kwambiri, kukula kwakukulu kwa gawo komanso zofunikira kwambiri siziyenera kugwiritsidwa ntchito.
Thechitoliro chachitsulo chosasunthika chotentha kwambiriImatha kugwira ntchito pamalo ozizira kwambiri a -45~-110 ℃. Ubwino waukulu wa chitoliro chachitsulo chosasunthika chotentha pang'ono ndikuti imatha kugwira ntchito pamalo otsika kwambiri, zomwe sizingafanane ndi chitoliro chachitsulo chosasunthika chokhazikika. Chitoliro chachitsulo chosasunthika chotsika kwambiri chili ndi mphamvu zabwino komanso kulimba pang'ono, ndipo chimagwiritsidwa ntchito kwambiri popanga zida zotentha pang'ono m'mafakitale amafuta, mankhwala, feteleza ndi mafakitale ena okhala ndi kutentha kogwira ntchito kwa -45~-110 ℃. Ndi chitukuko cha mafakitale oyenerera, zofunikira pa zipangizo sizimangokhala pazofunikira zoyambira monga katundu wamakina ndi katundu wowotcherera, komanso zofunikira za kukana dzimbiri kwa mapaipi otsika kutentha kwa H2S.
Chitoliro chachitsulo chosasunthika chotentha kwambiriimagwira ntchito pa uinjiniya wa mapaipi m'malo otentha kwambiri. Pali njira ziwiri: kujambula kozizira ndi kugwedezeka kotentha. Kuchokera pamalingaliro a kapangidwe ka chitsulo, kupanga zitsulo, kugwedezeka, kutenthetsa ndi njira zina za chitoliro chachitsulo chosasunthika chotentha kwambiri ziyenera kulamulidwa mosamala kuti zitsimikizire kuti chitoliro chachitsulo chosasunthika chotentha kwambiri chili ndi mphamvu yabwino, kulimba komanso kukana dzimbiri. Pazofunikira zaukadaulo za chitoliro chachitsulo chosasunthika chotentha kwambiri, kukonzekera kupanga ndi mtengo wopangira chitoliro chachitsulo ziyenera kuganiziridwa mokwanira. Kapangidwe ka chitoliro chachitsulo chosasunthika chotentha kwambiri chiyenera kuwonetsetsa kuti chinthucho chili ndi mphamvu yoyenera, kulimba kwambiri kutentha kochepa, komanso njira yabwino yothanirana ndi kutentha. Kutha kusungunula bwino komanso kukana kusweka komwe kumabwera chifukwa cha hydrogen.
Muyezo waukulu wa chitoliro chachitsulo chosasunthika chotentha kwambiriASTM A333- Chitoliro chachitsulo chopanda msoko komanso cholumikizidwa kuti chigwiritsidwe ntchito pa kutentha kochepa
Zipangizo zotentha kwambirichitoliro chachitsulo chopanda msokozinthu: 16Mn, 10MnDG, 09DG, 09Mn2VDG, 06Ni3MoDG, ndi zina zotero.
