Chitoliro chachitsulo chosasunthika cha alloy ndi mtundu wa chitoliro chachitsulo chosasunthika, ndipo magwiridwe ake ndi apamwamba kwambiri kuposa chitoliro chachitsulo chosasunthika, chifukwa chitoliro chachitsulochi chili ndi Cr yambiri, ndipo kukana kutentha kwambiri, kukana kutentha kochepa komanso kukana dzimbiri ndikwabwino kuposa mapaipi ena achitsulo chosasunthika. Zosayerekezeka, kotero machubu a alloy amagwiritsidwa ntchito kwambiri mu mafuta, mankhwala, mphamvu zamagetsi, boiler ndi mafakitale ena. Chitoliro chachitsulo chosasunthika cha alloy (Chitoliro Chosasunthika cha Chitsulo) chili ndi gawo lopanda kanthu, mzere wautali wachitsulo wopanda zolumikizira mozungulira. Chitoliro chachitsulocho chili ndi gawo lopanda kanthu ndipo chimagwiritsidwa ntchito kwambiri ngati payipi yonyamulira madzi, monga mapaipi onyamulira mafuta, gasi wachilengedwe, gasi, madzi ndi zinthu zina zolimba. Poyerekeza ndi chitsulo cholimba monga chitsulo chozungulira, chitoliro chachitsulo chosasunthika cha alloy chili ndi mphamvu yofanana yopindika komanso yozungulira komanso kulemera kopepuka. Ndi chitsulo chotsika mtengo ndipo chimagwiritsidwa ntchito kwambiri popanga zigawo zomangamanga ndi zigawo zamakanika, monga mayendedwe amafuta. Kupanga zigawo za mphete ndi chitoliro chachitsulo chosasunthika cha alloy kungathandize kukweza kuchuluka kwa kugwiritsa ntchito zipangizo, kupangitsa kuti njira yopangira ikhale yosavuta, kusunga zipangizo ndi nthawi yokonza, monga mphete zozungulira, ma jack sets, ndi zina zotero, zomwe zakhala zikugwiritsidwa ntchito kwambiri popanga mapaipi achitsulo. Chitoliro chachitsulo chosasunthika cha alloy ndi chinthu chofunikira kwambiri pa zida zosiyanasiyana zachikhalidwe, ndipo mbiya, mbiya, ndi zina zotero ziyenera kupangidwa ndi chitoliro chachitsulo. Kuphatikiza apo, pamene gawo la mphete likukhudzidwa ndi kupanikizika kwa radial mkati kapena kunja, mphamvuyo imakhala yofanana. Chifukwa chake, mapaipi ambiri achitsulo chosasunthika cha alloy ndi mapaipi ozungulira.
Gulu:
Chitoliro chachitsulo chosapanga dzimbiri: imagwiritsidwa ntchito makamaka pa kapangidwe kake ndi kapangidwe ka makina. Zida zake zoyimira (mtundu): chitsulo cha kaboni 20, chitsulo cha 45; chitsulo cha alloy Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, ndi zina zotero.
Mapaipi achitsulo opanda msoko operekera madzi: amagwiritsidwa ntchito makamaka ponyamula mapaipi amadzimadzi mu uinjiniya ndi zida zazikulu. Zipangizo zoyimira (giredi) ndi 20, Q345, ndi zina zotero.
Mapaipi achitsulo opanda msoko a ma boilers otsika ndi apakati: amagwiritsidwa ntchito makamaka pa mapaipi otumizira madzi otsika ndi apakati m'maboiler a mafakitale ndi m'nyumba. Zipangizo zoyimira ndi 10, 20 zitsulo.
Mapaipi achitsulo opanda msoko a ma boilers okwera kwambiri: amagwiritsidwa ntchito makamaka pa ma header ndi mapaipi amadzimadzi oyendera kutentha kwambiri komanso kuthamanga kwambiri pama boilers m'mafakitale amagetsi ndi mafakitale amagetsi a nyukiliya. Zipangizo zoyimira izi ndi 20G, 12Cr1MoVG, 15CrMoG, ndi zina zotero.
Mapaipi achitsulo opanda msoko opangira feteleza wothamanga kwambiri: amagwiritsidwa ntchito makamaka pa mapaipi amadzimadzi otentha kwambiri komanso amphamvu kwambiri pazida za feteleza. Zipangizo zoyimira ndi 20, 16Mn, 12CrMo, 12Cr2Mo, ndi zina zotero.
Mapaipi achitsulo opanda msoko ophwanyira mafuta: amagwiritsidwa ntchito makamaka mu ma boiler, ma heat exchanger ndi mapaipi awo amadzimadzi otumizira mu ma smelting oil smelter. Zipangizo zake zoyimira ndi 20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, ndi zina zotero.
Mapaipi achitsulo opanda msoko a masilinda a gasi: amagwiritsidwa ntchito kwambiri popanga masilinda osiyanasiyana a gasi ndi hydraulic. Zipangizo zake zoyimira ndi 37Mn, 34Mn2V, 35CrMo ndi zina zotero.
Mapaipi achitsulo osapindika otenthedwa opangira zida zamagetsi: amagwiritsidwa ntchito makamaka popanga zothandizira zamagetsi, masilinda ndi zipilala m'migodi ya malasha, komanso masilinda ndi zipilala zina zamadzimadzi. Zipangizo zake zoyimira ndi 20, 45, 27SiMn, ndi zina zotero.
Chitoliro chachitsulo chopanda msoko chokokedwa ndi ozizira kapena chopindidwa ndi ozizira: chimagwiritsidwa ntchito makamaka pakupanga makina, zida zokanikiza mpweya, zomwe zimafuna kulondola kwakukulu komanso kumaliza bwino pamwamba. Zinthu zake zoyimira ndi 20, 45 zitsulo, ndi zina zotero.
