ASTM A210 / A210MYog tus qauv tshwj xeeb hu"Tus Qauv Tshwj Xeeb rau Seamless Nruab Nrab-} cov roj carbon steel boiler thiab tus supertheat tres"tsim los ntawmAmerican Society rau Kev Ntsuam Xyuas thiab Khoom (ASTM)Cov. Hauv qab no yog cov lus qhia ntxaws ntxaws rau cov qauv no:
1. Tsw
Cov Ntawv Thov:
Haum rauBoiler Tubes, Flue Leeg, Suav nrogKev nyab xeeb xaus, domes, txhawb nqa hlab, ThiabSoj Ntsuam Superheater.
Qhov loj loj:
Feem ntau npogOd los ntawm 1/2 nti mus rau 5 nti (12.7 hli txog 127 hli)ThiabTsawg kawg cov phab ntsa tuab ntawm 0.035 nti mus rau 0.500 nti (0.9 hli rau 12.7 hli).
Lwm qhov ntau thiab tsawg yuav muab tau yog tiasTxhua yam yuav tsum muajNtawm tus qauv tau ntsib.
Cov Kev Kawm Txhua Yam Yuav Tsum Tsis SivRau tub nrogID <1/8 nti (3.2 hli)Lossisthickness <0.015 nti (0.4 hli).
2. Tshuaj lom neeg sib xyaw
Qeb A-1:
C Tsawg dua lossis sib npaug rau 0.27%, Mn tsawg dua los yog sib npaug rau 0.93%, SI ntau dua lossis sib npaug rau 0.1%, P tsawg dua lossis sib npaug rau 0.035%, S tsawg dua los yog sib npaug rau 0.035%.
Qib C:
C Tsawg dua lossis sib npaug rau 0.35%, MN 0.29-1.06%, SI ntau dua lossis sib npaug rau 0.1%, P tsawg dua lossis sib npaug rau 0.035%, S tsawg dua los yog sib npaug rau 0.035%.
3. Cov Khoom Siv Kho Tshuab
Lub zog tensile:
Qeb A-1: Ntau dua lossis sib npaug rau 415 MPa
Qib C: Loj dua los yog sib npaug rau 485 MPa
Paib lub zog:
Qeb A-1: Loj dua lossis sib npaug rau 255 MPa
Qib C: Loj dua los yog sib npaug rau 275 MPa
Elongation:
Ob chav kawm qib: ntau dua los yog sib npaug rau 30%
4. Kev Tsim Kho Cov Txheej Txheem
Txoj kev sib sau:
Cov txheej txheem txheej txheemUa kom muaj kev ncaj ncees kev ncaj ncees thiab kev sib dhos rauhigh - kub thiab high -}}} cov chaw ib puag ncig.
Kev Kho Cua Sov:
Yuav tsum tau raws li ib qib thiab xaus -} siv, Nrog cov hau kev txiav txim raws li.
5. Kev tshuaj xyuas & kev sim
Tensile xeem:
1 sample per batch ≤50 tubes; 2 samples per batch >50 leeg.
Kaj ntsuam xyuas:
1 piv txwv rau ib pob(Tsis yog siv rau txoj kev nyab xeeb), kuaj ntawmob qho kawg.
RauQib C Tubes tsawg dua lossis sib npaug rau 2.375 ntiv (60.3 hli), kua muag / tawg ntawm 12 teev thiab 6 teev tsis yog thaj chaw rau kev xyeej.
Flaring kuaj:
1 piv txwv rau ib pob(Tsis yog siv rau cov tiaj tiaj), kuaj ntawmob qho kawg.
Kuaj Hardness:
2 cov qauv rau ib pobRauBrinell lossis rockwell hardness.
Hydrostatic kuaj lossis ndt:
Txhua lub raj raj yuav tsum yauv hydrostatic kuaj, Tshwj tsis yogNDT yog teev los ntawm tus neeg yuav khoom.
6. Cim
Tubes yuav tsum tau cim nrogTus Qauv Qauv, Qib, Qhov Coob, Ntau Ntau Ntau, thiab tus lej cua sovRau kev sib cav thiab tswj kev nyab xeeb.
Cov Ntawv Thov
Vim lawvsiab - kub kuj, siab ntev, siab ntev, thiab tawv, ASTM A210 leegYog siv dav hauvFais fab cog boilers, muaj cov rwj habers, superheaters, Thiab lwm yamhigh - cov khoom siv siab. Cov qib sib txawvTuaj yeem xaiv raws liKev Ua Haujlwm Tshwj Xeeb.
