Chitoliro chachitsulo chopanda msokoe ndi chingwe chachitsulo chachitali chokhala ndi gawo lopanda kanthu komanso chopanda mipata yozungulira. Chifukwa cha njira yake yapadera yopangira, ili ndi mphamvu zambiri komanso kukana kupanikizika bwino. Mapaipi achitsulo opanda msoko omwe ayambitsidwa nthawi ino akuphatikizapo zipangizo ziwiri ndi ma specifications: 15CrMoG grade, specifications 325×14 ndi12Cr1MoVGgiredi, specifications 325×10.

Makhalidwe ndi ntchito za15CrMoGchitoliro chachitsulo
15CrMoG ndi chitsulo cha chromium-molybdenum alloy, zomwe zigawo zake zazikulu ndi kaboni (C), chromium (Cr), molybdenum (Mo), ndi zina zotero. Chida ichi chili ndi mphamvu zambiri, kukana okosijeni bwino komanso kukana kutentha kwambiri, makamaka m'malo otentha kwambiri komanso opanikizika kwambiri. Kuphatikiza apo, 15CrMoG ilinso ndi magwiridwe antchito abwino komanso kuthekera kogwiritsa ntchito bwino.

Ntchito
Mapaipi achitsulo chopanda msoko opangidwa ndi 15CrMoG amagwiritsidwa ntchito makamaka pa mapaipi ndi zida zotenthetsera kwambiri komanso zopanikizika kwambiri, ndipo amagwiritsidwa ntchito kwambiri m'magawo otsatirawa:

Makampani opanga magetsi: ma boiler superheaters, ma reheaters, ma headers ndi mapaipi akuluakulu a nthunzi m'mafakitale opangira magetsi.
Makampani opanga mankhwala: njira zopapira mapaipi a ma reactor otentha kwambiri mu zida zama mankhwala.
Makampani opanga mafuta: mapaipi otentha kwambiri komanso osinthira kutentha m'mafakitale oyeretsera mafuta.
Chitoliro chachitsulo ichi chimatha kusunga bwino makina kutentha kwambiri, ndipo chimagwiritsidwa ntchito kutentha kwa nthawi yayitali pakati pa 500°C ndi 580°C.
Makhalidwe ndi ntchito za mapaipi achitsulo a 12Cr1MoVG
12Cr1MoVG ndi chitsulo chapamwamba kwambiri cha chromium-molybdenum-vanadium chomwe chimadziwika ndi mphamvu zambiri, kukana kukwera bwino, komanso kukana dzimbiri komanso okosijeni. Poyerekeza ndi 15CrMoG, imawonjezera vanadium (V) pang'ono, zomwe zimawonjezera kukana kwake kutentha kwambiri komanso kukhazikika.
Ntchito
Mapaipi achitsulo opanda msoko opangidwa ndi 12Cr1MoVG nthawi zambiri amagwiritsidwa ntchito m'malo otentha kwambiri komanso opanikizika kwambiri, ndipo mitundu yawo yogwiritsira ntchito imaphatikizapo:
Mphamvu: ma superheater otentha kwambiri, ma reheater ndi mapaipi m'mafakitale amphamvu otentha komanso m'mafakitale amphamvu a nyukiliya.
Makampani opanga mafuta: zida zamakemikolo ndi mapaipi okhala ndi kutentha kwambiri komanso kuthamanga kwambiri.
Kupanga ma boiler: kupanga machubu a boiler okhala ndi mphamvu zambiri pazida zomwe zili ndi mphamvu zambiri zogwirira ntchito.
Chitoliro chachitsulo chamtunduwu ndi choyenera kugwiritsidwa ntchito kwa nthawi yayitali kutentha kopitilira 570°C ndipo chimakhala ndi mphamvu yolimba komanso kulimba kwamphamvu.
Chitoliro chachitsulo cha 15CrMoG chokhala ndi 325×14 ndi chitoliro chachitsulo cha 12Cr1MoVG chokhala ndi 325×10 chili ndi mfundo zakezake. Zonsezi ndi mapaipi achitsulo opanda zingwe ogwira ntchito kwambiri ndipo amagwiritsidwa ntchito kwambiri m'mafakitale otentha kwambiri komanso opanikizika kwambiri monga mphamvu, petrochemicals, ndi mankhwala. Kutengera ndi malo ogwiritsira ntchito, ogwiritsa ntchito amatha kusankha chida choyenera kwambiri cha chitoliro chachitsulo kuti akwaniritse zosowa zopangira.
