Seamless alloy simbi pombi stockASTM A335 P91, pombi yesimbi isina musono inoshandiswa mumachubhu ebhailer, machubhu ekupisa uye mamwe maindasitiri, anogona kushandiswa semapombi esimbi epamusoro-tembiricha yepamusoro uye anodzoreredza mune subcritical uye supercritical boilers ane tembiricha yemudhuri ≤625 ° C, pamwe nemadziro High-tembiricha misoro. uye mapaipi eutsi ane tembiricha ≤600 ℃ inogona zvakare kushandiswa seye nyukireya magetsi ekupisa kupisa uye petroleum yekupwanya unit. choto machubhu.
ASTM A335 P91 isimbi yepamusoro-tembiricha yealloy iri pasi-alloy chromium-molybdenum simbi. Inoshandiswa zvakanyanya mumapaipi uye midziyo pasi pekushisa kwepamusoro uye nzvimbo dzekumanikidza, dzakadai se petrochemical, magetsi emagetsi, zvidyarwa zvemagetsi enyukireya uye mamwe minda. Izvo zvakakosha zvechinyorwa ichi chromium, molybdenum, mhangura, manganese, nesilicon, phosphorus, sarufa uye zvimwe zvinhu. Izvo zviri mukati mechromium uye molybdenum zvakakwirira, izvo zvinogona kuvandudza tembiricha yekudzivirira uye oxidation kuramba kwezvinhu.
ASTM A335 P91 zvinhu zvine zvakanakisa zvemuchina zvivakwa uye zvichiri kugona kuchengetedza simba rakanaka uye kuomarara pasi petembiricha yepamusoro uye nzvimbo dzekumanikidza. Izvo zvinyorwa zvakare zvinopikisa zvakanyanya kune oxidation, iyo inogona kunyatso wedzera hupenyu hwebasa hwemapombi nemidziyo. Mukuwedzera, iyo nyaya inewo yakanaka welding performance, ichiita kuvaka nekugadzirisa zviri nyore.
Nekuti ASTM A335 P91 zvinhu zvine izvi zvakanakisa zvivakwa, zvinoshandiswa zvakanyanya mune imwe tembiricha yepamusoro uye yakanyanya kudzvanywa nharaunda. Semuenzaniso, muindasitiri yepetrochemical, mapaipi uye midziyo yakagadzirwa neASTM A335 P91 inogona kutsungirira kukukurwa kwemakemikari nekuora pasi pekupisa kwakanyanya uye kumanikidzwa, kuve nechokwadi chekushanda kwakachengeteka kwemidziyo. Muminda yemagetsi emagetsi uye zvidyarwa zvemagetsi enyukireya, mapaipi uye midziyo yakagadzirwa neASTM A335 P91 inogona kumira nekuora uye kukukurwa kwemhute nemhute yemvura uye mamwe midhiya pasi pekupisa kwakanyanya uye kumanikidzwa, kuve nechokwadi chekushanda kwakajairika kwemidziyo.
