Musono chiwanikwa simbi pombi stockASTM A335 P91, mapaipi esimbi asina musono anoshandiswa mumachubhu eboiler, machubhu ekupisa kupisa nemamwe maindasitiri, anogona kushandiswa semapaipi esimbi ekupisa kwakanyanya uye maheater anodzoreredza kupisa mumaboiler asina kukosha uye akakosha ane tembiricha yemadziro ≤625°C, pamwe nemadziro. Maheaders ekupisa kwakanyanya uye mapaipi emhepo ane tembiricha ≤600℃ anogonawo kushandiswa semachubhu ekupisa emagetsi enyukireya uye machubhu efurnace anopwanya petroleum.
ASTM A335 P91 isimbi yesimbi inodziya zvakanyanya ine chromium-molybdenum steel ine alloy yakaderera. Inoshandiswa zvakanyanya mumapaipi nemidziyo munzvimbo dzinopisa zvakanyanya uye dzakanyanya kumanikidzwa, dzakadai se petrochemical, magetsi, manuclear power plants nedzimwe nzvimbo. Zvikamu zvikuru zvechinhu ichi i chromium, molybdenum, copper, manganese, silicon, phosphorus, sarufa nezvimwe zvinhu. Chromium ne molybdenum zvakakwirira, izvo zvinogona kuvandudza kuramba kupisa kwakanyanya uye kuramba oxidation kwezvinhu.
Chinhu cheASTM A335 P91 chine hunhu hwakanaka hwemakanika uye chinogona kuramba chakasimba uye chakasimba mumamiriro ekunze ekudziya kwakanyanya uye kumanikidzwa kwakanyanya. Chinhu ichi chinodzivirirawo kuoxidation, izvo zvinogona kuwedzera hupenyu hwemapombi nemidziyo. Pamusoro pezvo, chinhu ichi chinewo kushanda kwakanaka kwekubatanidza, zvichiita kuti kuvaka nekugadzirisa zvive nyore.
Nekuti zvinhu zveASTM A335 P91 zvine hunhu hwakanaka, zvinoshandiswa zvakanyanya munzvimbo dzinopisa zvakanyanya uye dzine kumanikidzwa kwakanyanya. Semuenzaniso, muindasitiri yemafuta, mapaipi nemidziyo yakagadzirwa neASTM A335 P91 inogona kutsungirira kukanganiswa kwemakemikari nengura pasi pekupisa kwakanyanya uye kumanikidzwa, zvichiita kuti michina ishande zvakachengeteka. Muminda yemagetsi nemagetsi enyukireya, mapaipi nemidziyo yakagadzirwa neASTM A335 P91 inogona kutsungirira kukanganiswa kwemhepo nemhepo neutsi hwemvura nezvimwe zvinhu zvinobuda pasi pekupisa kwakanyanya uye kumanikidzwa, zvichiita kuti michina ishande zvakanaka.
