Alloy seamless simbi pombi chinhu chepamusoro-chinoshanda chinoshandiswa zvakanyanya muindasitiri uye kuvaka. Chinhu chayo chikuru ndechekuvandudza magadzirirwo emagetsi, kushomeka kwekudzivirira uye kupisa kwakanyanya kwepombi dzesimbi nekuwedzera zvinhu zvakasiyana-siyana, sechromium, molybdenum, nickel, etc.

ASTM A335P series:

P5: P5 simbi pombi ine 5% chromium uye 0.5% molybdenum, ine yakanaka oxidation kuramba uye yakakwirira tembiricha simba, uye inowanzoshandiswa kupisa tembiricha chiutsi mapaipi uye petrochemical indasitiri.
P9: P9 simbi pombi ine 9% chromium uye 1% molybdenum, ane yakakwirira oxidation kuramba uye corrosion kuramba kupfuura P5, uye yakakodzera tembiricha uye high pressure nharaunda.
P11: P11 simbi pombi ine 1.25% chromium uye 0.5% molybdenum, ine yepamusoro yakazara kuita, uye inoshandiswa zvakanyanya mukupisa kupisa boilers uye kupisa kunopisa.
P22: P22 simbi pombi ine 2.25% chromium uye 1% molybdenum, ine yakakwirira tembiricha simba uye oxidation kuramba, uye inowanzoshandiswa kupisa tembiricha uye yakakwirira kumanikidzwa mapaipi mumagetsi zvidyarwa uye petrochemical indasitiri.
P91: P91 simbi pombi ndeyepamusoro chromium uye yakakwirira molybdenum simbi, ine 9% chromium uye 1% molybdenum, uye ine trace uwandu vanadium uye nitrogen. Iyo ine yakanyanya kupisa tembiricha simba uye inokambaira simba uye inoshandiswa zvakanyanya mu supercritical uye Ultra-supercritical simba zvidyarwa.
ASTM A213T series:

T11: T11 simbi pombi ine 1.25% chromium uye 0.5% molybdenum, akafanana P11, uye inonyanya kushandiswa kupisa kupisa exchangers uye boilers.
T22: T22 simbi pombi ine 2.25% chromium uye 1% molybdenum, akakodzera yakakwirira tembiricha uye high pressure nharaunda, uye rinoshandiswa zvikuru muzvidyarwa simba uye petrochemical maindasitiri.
T91: T91 simbi pombi yakafanana neP91, ine 9% chromium uye 1% molybdenum, uye ine vanadium uye nitrogen. Iyo ine yakanakisa tembiricha yesimba uye inokambaira kuramba uye inokodzera supercritical uye Ultra-supercritical simba zvidyarwa.
EN 10216-2:
10CrMo9-10: Iyi iEuropean standard alloy simbi pombi ine chromium uye molybdenum, ine yakanaka yakakwirira tembiricha kusimba uye kusaita ngura, inowanzoshandiswa mumagetsi emagetsi uye petrochemical maindasitiri.
Alloy seamless simbi mapaipi anonatsiridza zvakanyanya kushanda kwakazara kwemapombi esimbi nekuwedzera chaiwo alloy zvinhu kusimbi, uye akakodzera kune akasiyana akanyanyisa mamiriro ekushanda. P akateedzana uye T akateedzana yakakwira chromium uye yakakwira molybdenum simbi mapaipi, akadai seP91 uye T91, inomiririra kutungamira kwemazuva ano tembiricha yepamusoro uye yakanyanya kudzvanywa zvinhu uye inoshandiswa zvakanyanya mu supercritical uye Ultra-supercritical magetsi zvidyarwa. Kusarudza iyo yakakodzera alloy seamless simbi pombi zvinhu hazvigone chete kuvimbisa kuchengetedza uye kugadzikana kushanda kweprojekiti, asiwo zvakanyanya kunatsiridza hupenyu hwebasa uye kugona kwemidziyo.
