FAQ
Q1: "TP2" txhais li cas? Nws puas zoo ib yam li C12200?
A: Yog lawm, TP2 yog Suav lub npe rau C12200.TP2 yog ib qib uas tau teev tseg raws li tus qauv SuavGB/T 17791rau cua txias thiab tub yees tooj liab tubes. Nws yog phosphorus -deoxidized tooj liab nrog99.9% tooj liab thiab 0.015-0.040% phosphorus- Cov tshuaj zoo ib yam rau ASTM C12200. TP2 yog siv dav hauv HVAC daim ntawv thov hauv khw Esxias.
Q2: Dab tsi yog qhov txawv ntawm ASTM B75 thiab ASTM B111 rau C12200 raj?
A: ASTM B75yog raugeneral engineering applications- Cov kav dej, cov kav dej dav dav, thiab kev siv tshuab.ASTM B111yog tshwj xeeb raucondensers thiab tshav kub exchangers- nws muaj qhov nruj dua qhov ntev, qhov kev xav tau tshwj xeeb rau kev nthuav dav lub raj, thiab cov kev ntsuas ntxiv (eddy tam sim no, hydrostatic). Rau kev pab cuam tshav kub exchanger,ib txwm qhia ASTM B111.
Q3: Cov raj TP2 / C12200 puas tuaj yeem siv rau cov dej hiav txwv txias?
A: Tsis pom zoo.C12200 (ntshiab tooj liab nrog phosphorus) muaj corrosion kuj zoo nyob rau hauvdej tshiab thiab chav dej condensate, mas indej hiav txwv, nws muaj kev cuam tshuam rau pitting thiab yaig-corrosion, tshwj xeeb tshaj yog nyob rau ntawm qhov nrawm tshaj 1.5 m / s. Rau cov dej hiav txwv, xaivC70600 (90/10 tooj liab-nickel)los yogC71500 (70/30 tooj liab-nickel) .
Q4: Dab tsi yog qhov ntsuas hydrogen embrittlement hais hauv ASTM B75?
A: Covhydrogen embrittlement testyog xav tau rau oxygen- tooj liab dawb (C10100, C10200, thiab lwm yam) tab sis kuj tseem cuam tshuam rau C12200. Qhov kev sim kuaj pom muaj cov pa oxygen uas tuaj yeem cuam tshuam nrog hydrogen hauv kev txo cov huab cua (xws li brazing / vuam), ua rau sab hauv tawg.C12200, raug deoxidized, muaj kev tiv thaiv zoo rau hydrogen embrittlement- qhov no yog qhov txiaj ntsig tseem ceeb tshaj C11000 (ETP tooj liab).
Q5: Kuv yuav tsum txiav txim siab dabtsi rau khoov rau hauv U- raj?
A: Koj yuav tsum tau xajO61 (ntxiv)npau taws. Lub H55 (lub teeb kos) thiab H80 (tawv tawv) tempers muaj zog dua tab sistxo ductilitythiab tej zaum yuav tawg thaum U- khoov. Cov lus hais txog cov khoom siv dag zog qhia tau hais tias muaj zog tensile ntau - cov raj annealed yog nyob rau hauv qis kawg ntawm 221-379 MPa ntau yam, muab qhov siab tshaj plaws formability.
Q6: Puas yog ASTM B75 C12200 haum rau cov dej haus?
A: Yog lawm.C12200 yog dav siv rau cov kav dej thiab cov dej haus. Nws ua tau raws li qhov xav tau ntawmNSF/ANSI 61rau cov dej haus system Cheebtsam thiab muaj zoo heev corrosion kuj rau cov dej tshiab. Txawm li cas los xij, nco ntsoov paub meej nrog koj cov kav dej hauv zos.
Q7: Dab tsi yog qhov thermal conductivity ntawm C12200 piv rau lwm cov khoom siv hluav taws xob sib hloov?
A: C12200 muaj thermal conductivity zoo heev ntawm 339 W/m-K (196 BTU/ft²/ft/h/℃F).Rau kev sib piv:
Admiralty tooj dag (C44300): ~ 111 W/m-K
90/10 tooj liab-nickel (C70600): ~ 45 W/m-K
316 Stainless Hlau: ~ 16 W / m-K
Titanium Qib 2: ~ 17 W / m-K
Qhov no ua rau C12200 yog qhov kev xaiv zoo tshaj plaws thaumsiab tshaj qhov kub hloovyog qhov tseem ceeb thiab corrosion tej yam kev mob me me.
Q8: Qhov txawv ntawm JIS H3300 C1220T thiab ASTM B111 C12200 yog dab tsi?
A: C1220T yog JIS sib npaug ntawm ASTM C12200.Cov tshuaj muaj pes tsawg leeg yog qhov tseem ceeb tib yam (Cu Ntau dua lossis sib npaug rau 99.9%, P 0.015-0.040%). Qhov sib txawv tseem ceeb yog nyob rau hauv:
Temper npe(JIS siv O, 1/2H, H; ASTM siv O61, H55, H80)
Dimensional kam rau ua(JIS muaj "Tsev Kawm Ntawv Qib Siab" thiab "Tshooj Tshwj Xeeb"; ASTM muaj nws tus kheej cov lus kam rau ua)
Cov qoob loo loj yuav tsum(ob qho tib si muaj qhov zoo sib xws rau annealed tempers)
Rau feem ntau cov ntawv siv hluav taws xob sib hloov, lawv tuaj yeem hloov pauv tau, tab sis nco ntsoov paub meej tias tus qauv twg tau teev tseg hauv koj cov ntaub ntawv qhov project.
Q9: Dab tsi tsis yog -kev kuaj kev puas tsuaj (NDT) yuav tsum muaj rau ASTM B111 C12200 raj?
A: ASTM B111 xav taueddy tam sim no xeem (ET)Raws li ASTM E243 yog thawj NDT txoj kev. Cov kev ntsuam xyuas ntxiv yuav muaj xws li:
Kev ntsuam xyuas hydrostatic(tsawg kawg 7000 psi fiber ntau, tsis pub tshaj 1000 psi tshwj tsis yog tau teev tseg)
Kev kuaj pneumatic(los ntawm kev pom zoo)
Kev kuaj ultrasonic (UT)(los ntawm kev pom zoo)
Nco ntsoov thov tuszeb xeem daim ntawv pov thawjlees paub qhov twg NDT txoj kev raug siv.
Q10: Puas yog C12200 haum rau siab -kev siv kub?
A: Yog, nyob rau hauv kev txwv.C12200 tswj cov khoom siv kho kom zoo mus txog kwv yees li200 ° F (400 ° F). Tshaj qhov kub no, nkag thiab oxidation ua kev txhawj xeeb. Lub melting point yog 1083℃(1981℃F), tab sis rau kev pabcuam txuas ntxiv, khaws kub hauv qab 200-250 degree. Rau kev siv kub siab dua (300-400 degree), xav txognpib tsib xee alloyslos yog qhia covHR50 (kho, kev ntxhov siab-relieved)temper rau zoo creep kuj.
