Mapaipi achitsulo chosasunthika a alloy amapangidwa ndi chitsulo chosungunuka ngati zinthu zopangira ndipo amapangidwa kudzera mu njira monga kugwedezeka kotentha, kugwedezeka kozizira kapena kukoka kozizira. Poyerekeza ndi mapaipi wamba achitsulo cha kaboni, mapaipi achitsulo chosungunuka a alloy ali ndi mphamvu zapamwamba kwambiri zamakaniko, kukana kutentha kwambiri, kukana dzimbiri komanso mawonekedwe apadera akuthupi ndi a mankhwala chifukwa chowonjezera zinthu za alloy monga chromium, molybdenum, nickel ndi vanadium. Amagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta, uinjiniya wa mankhwala, mphamvu, ma boiler, ndi kupanga makina.
Zochitika zazikulu zogwiritsira ntchito
1. Makampani opanga mafuta
Mapaipi a mayunitsi ophwanya mafuta: amafunika kukana kutentha kwambiri, kukana kuthamanga kwambiri komanso mphamvu zotsutsana ndi dzimbiri la sulfure
Mapaipi a zida za feteleza: Ayenera kukhala opirira dzimbiri la ammonia, urea, ndi zina zotero.
Mapaipi a zida za polyester: Amafuna ukhondo wambiri komanso kukana dzimbiri la mankhwala
2. Makampani Opanga Mphamvu
Mapaipi a ma boiler a siteshoni yamagetsi: Machubu a boiler okhala ndi mphamvu yothamanga kwambiri, machubu a superheater, ndi zina zotero, ayenera kukhala opirira kutentha kwambiri.
Mapaipi amagetsi a nyukiliya: Amafunika mphamvu zapadera zotsutsana ndi ma radiation
3. Kupanga Makina
Chitoliro cha hydraulic pipe: Kulondola kwambiri komanso kufunikira kwamphamvu kwambiri
Machubu onyamula: Amafuna kukana kwambiri kuvala
Chitoliro cha shaft chotumizira magalimoto: Mphamvu yayikulu, kulimba kwambiri
4. Zamlengalenga
Machubu a injini: Machubu a aloyi osatentha kwambiri
Machubu a hydraulic system: Zofunikira pa mphamvu yapamwamba kwambiri
Miyezo ndi zofunikira za zinthu zomwe zimagwiritsidwa ntchito
1. Miyezo ya mndandanda wa ASTM
ASTM A335: Mapaipi achitsulo chopanda msoko ogwiritsidwa ntchito kutentha kwambiri, chitsulo cha ferritic alloy
Manambala a chitsanzo: Chitoliro cha P5 Alloy, P9, P11, P22, P91, ndi zina zotero.
Mphamvu yotentha kwambiri, mphamvu ya antioxidant, magwiridwe antchito ofooka
Kugwiritsa ntchito: Ma boiler a siteshoni yamagetsi, mayunitsi ophwanya mafuta
ASTM A213: Mapaipi opanda msoko achitsulo cha alloy cha ma boiler, ma superheater ndi ma heat exchanger
Mtundu wa botolo: T5, T9, T11, T22, T91, ndi zina zotero.
Mphamvu yolimba kutentha kwambiri komanso mphamvu yoteteza ku ma antioxidants
2. Mndandanda Wokhazikika wa DIN/EN
DIN 17175/EN 10216-2: Mapaipi achitsulo opanda msoko ogwiritsira ntchito kutentha kwambiri
Giredi: 13CrMo4-5, 10CrMo9-10, X10CrMoVNb9-1 (P91)
Mphamvu yokwera kwambiri komanso magwiridwe antchito owotcherera
3. Mndandanda Wokhazikika wa GB
GB 5310: Mapaipi achitsulo opanda msoko a ma boiler opanikizika kwambiri
Giredi:15CrMoG, 12Cr1MoVG, 10Cr9Mo1VNb, ndi zina zotero.
Mphamvu yotentha kwambiri, mphamvu ya antioxidant, magwiridwe antchito a ndondomeko
GB 9948: Mapaipi achitsulo opanda msoko opukutira mafuta
Giredi: 12CrMo, 15CrMo, 1Cr5Mo, ndi zina zotero.
Yolimba ku dzimbiri la sulfure lotentha kwambiri komanso kuwonongeka kwa haidrojeni
Mphamvu yotentha kwambiri, magwiridwe antchito owotcherera
Zinthu zodziwika bwino zophatikiza ndi ntchito zawo
Chromium (Cr): Imalimbitsa kukana kwa okosijeni, kukana dzimbiri, komanso imawonjezera mphamvu yotentha kwambiri
Molybdenum (Mo): Imalimbitsa mphamvu yotentha komanso imateteza kuzizira kwambiri
Nickel (Ni): Imalimbitsa kulimba, kukana dzimbiri, komanso imalimbitsa magwiridwe antchito otsika kutentha
Vanadium (V): Imachepetsa kukula kwa tirigu, imawonjezera mphamvu ndi kulimba
Niobium (Nb): Imalimbitsa kukana kwa kukwawa ndikuwongolera luso la kuwotcherera
Titanium (Ti): Ma carbide okhazikika, omwe amawonjezera kukana dzimbiri pakati pa tinthu tating'onoting'ono

Mapaipi achitsulo chosasunthika, monga chinthu chofunikira kwambiri m'mafakitale, magwiridwe antchito awo ndi ubwino wawo zimakhudza mwachindunji magwiridwe antchito otetezeka komanso moyo wautumiki wa zida. Kusankha bwino miyezo ndi zofunikira za zipangizo, komanso kuwongolera mosamala njira zopangira ndi kuwunika kwabwino, ndi chitsimikizo chofunikira kwambiri kuti zitsimikizire kuti makina apaipi akugwira ntchito modalirika.
