Pombi yesimbi isina musono yeAlloy chinhu chinoshandiswa zvakanyanya mumaindasitiri nekuvaka. Chinhu chikuru chayo ndechekuvandudza hunhu hwemakanika, kuramba ngura uye kuramba kupisa kwakanyanya kwemapombi esimbi nekuwedzera zvinhu zvakasiyana-siyana zve alloy, zvakaita se chromium, molybdenum, nickel, nezvimwewo. Izvi zvinotevera zvimwe zvezvinhu zvinowanzo shandiswa papombi yesimbi isina musono yeAlloy:

ASTM A335Nhevedzano dzeP:

P5: Pombi yesimbi yeP5 ine 5% chromium uye 0.5% molybdenum, ine simba rakanaka rekudzivirira oxidation uye simba rekupisa kwakanyanya, uye inowanzoshandiswa mumapaipi emhepo inopisa zvakanyanya uye indasitiri yepetrochemical.
P9: Pombi yesimbi yeP9 ine 9% chromium uye 1% molybdenum, ine resistance yakakura yekuoxidation uye resistance ngura kupfuura P5, uye yakakodzera tembiricha yakakwira uye pressure yakakwira.
P11: Pombi yesimbi yeP11 ine 1.25% chromium uye 0.5% molybdenum, ine mashandiro akazara, uye inoshandiswa zvakanyanya mumaboilers ane tembiricha yepamusoro uye ma heat exchangers.
P22: Pombi yesimbi yeP22 ine 2.25% chromium uye 1% molybdenum, ine simba rekupisa kwakanyanya uye inodzivirira oxidation, uye inowanzoshandiswa mumapaipi ekupisa kwakanyanya uye kumanikidzwa kwakanyanya mumafekitori emagetsi uye indasitiri yepetrochemical.
P91: P91 steel pipe isimbi ine chromium yakawanda uye molybdenum yakawanda, ine 9% chromium uye 1% molybdenum, uye ine vanadium nenitrogen shoma. Ine simba rekupisa kwakanyanya uye simba rekukambaira uye inoshandiswa zvakanyanya mumagetsi emagetsi ane simba guru uye anonyanya kukosha.
ASTM A213T dzakatevedzana:

T11: Pombi yesimbi yeT11 ine 1.25% chromium uye 0.5% molybdenum, yakafanana neP11, uye inonyanya kushandiswa muma "heat exchangers" nema "boilers" ekupisa kwakanyanya.
T22: Pombi yesimbi yeT22 ine 2.25% chromium uye 1% molybdenum, yakakodzera nzvimbo dzinopisa zvakanyanya uye dzine kumanikidzwa kwakanyanya, uye inoshandiswa zvakanyanya mumafekitori emagetsi nemaindasitiri epetrochemical.
T91: Pombi yesimbi yeT91 yakafanana neP91, ine 9% chromium uye 1% molybdenum, uye ine vanadium nenitrogen. Ine simba rakanaka kwazvo pakupisa kwepamusoro uye inodzivirira kukambaira uye yakakodzera kune mafekitori emagetsi anonyanya kukosha uye anonyanya kukosha.
EN 10216-2:
10CrMo9-10: Iyi ipombi yesimbi yemhando yeEuropean alloy ine chromium nemolybdenum, ine simba rakanaka rekupisa kwepamusoro uye inodzivirira ngura, inowanzoshandiswa mumafekitori emagetsi nemaindasitiri epetrochemical.
Mapaipi esimbi asina musono anovandudza mashandiro akazara emapaipi esimbi nekuwedzera zvinhu zve alloy kusimbi, uye akakodzera mamiriro akasiyana-siyana ekushanda akanyanya. Mapaipi esimbi ane chromium yakawanda uye molybdenum yakawanda, akadai seP91 neT91, anomiririra mafambiro ekugadzirwa kwezvinhu zvemazuva ano zvinopisa zvakanyanya uye zvinomanikidzwa zvakanyanya uye anoshandiswa zvakanyanya mumagetsi emagetsi ane musono uye anonyanya musono. Kusarudza zvinhu zvakakodzera zvepaipi yesimbi isina musono hakungogone kuvimbisa kuchengetedzeka uye kushanda kwakasimba kwepurojekiti, asiwo kunovandudza zvakanyanya hupenyu hwebasa uye kushanda zvakanaka kwemidziyo.
