ASTM A106cov yeeb nkab hlau yog ib qho seamlesscov yeeb nkab hlautsim nyog siv rau hauv qhov kub thiab txias thiab qhov chaw siab.Nws yog dav siv hauv ntau qhov chaw xws li kev lag luam roj thiab roj av, cov chaw tsim hluav taws xob thiab cov chaw tsim tshuaj lom neeg.
Tshwj xeeb tshaj yog,ASTM A106 Qib BCov raj xa dej yog qhov nrov tshwj xeeb rau ntau daim ntawv thov vim nws muaj peev xwm ua tau raws li qhov xav tau ntawm feem ntau cov tshuab siv hauv kev tsim kho thiab nws tus nqi pheej yig.
ASME SA106 = ASTM A106.
ASME SA106 thiab ASTM A106 yog sib npaug hauv cov ntaub ntawv thiab cov khoom, thiab muaj cov qauv zoo ib yam, tab sis koom nrog cov koom haum tshaj tawm cov qauv sib txawv thiab siv los ua kom tau raws li cov txheej txheem pov thawj sib txawv.
Nominal Txoj kab uas hla: DN 6 - DN 1200 [NPS 1/8 - NPS 48];
Txoj kab uas hla sab nraud: 10.3 - 1219 hli [0.405 - 48 nti.];
Phab ntsa tuabyog raws li tau qhia hauvASME B 36.10.
Cov chav kawm tuab ntawm phab ntsa feem ntau yogTeem Caij 40thiabTeem Caij 80.
Cov yeeb nkab loj dua li tus qauv yuav siv tau, yog tias nws ua tau raws li txhua yam kev cai ntawm cov cai no.
LubASTM A106tus qauv muaj peb qib sib txawv,Qib A, Qib B, thiab Qib C.
Lub zog tawm los thiab lub zog tensile nce ntxiv nrog rau qib, uas yog siv los daws cov kev siv sib txawv.
Cov hlau yuav tsum tau tua hlau.
ASTM A106 cov yeeb nkab hlau yuav tsum tsim los ntawm kev siv ib qhocov txheej txheem tsim khoom tsis muaj kev sib txhuam.
Nyob ntawm seb cov yeeb nkab loj npaum li cas thiab daim ntawv thov tshwj xeeb, lawv tuaj yeem raug cais ntxiv rau hauvkub tiav lawmthiabtxias-koshom.
DN ≤ 40 [NPS ≤ 1 1/2], tuaj yeem ua kom kub tiav lossis txias kos, feem ntau txias kos.
DN ≥ 50 [NPS ≥ 2] yuav tsum tau ua kom tiav thaum kub. Cov kav hlau tsis muaj qhov sib txuas uas rub txias kuj muaj thaum thov.
Hauv qab no yog daim duab qhia txog cov txheej txheem tsim cov yeeb nkab hlau kub-ua tiav.
Cov duab kos ntawm cov khoom siv txias tuaj yeem saib tau los ntawm kev nyem rau ntawmASTM A556 Txias Kos Seamless Carbon Steel Tubes.
Cov kav hlau kub thiab txias kos seamless muaj cov khoom siv kho tshuab, qhov zoo ntawm qhov chaw, thiab qhov tseeb ntawm qhov ntev ntxiv rau qhov sib txawv ntawm qhov ntev.
Cov raj kub tiav lawm yog tsim los ntawm qhov kub siab thiab muaj zog dua tab sis cov nplaim ntxhib dua thiab qhov tseeb qis dua; thaum cov raj txias-kos yog tsim los ntawm kev hloov pauv yas ntawm chav tsev kub thiab muaj lub zog siab dua, cov nplaim du dua, thiab kev tswj qhov ntev meej dua, ua rau lawv haum rau cov ntawv thov uas xav tau kev ua haujlwm siab dua thiab kev ua tau zoo.
Txias-koscov tubing yuav tsum tau kho cua sov ntawm1200°F [650°C]lossis siab dua tom qab kos duab txias kawg.
Kub-tiav lawmcov kav hlau feem ntau tsis tas yuav kho cua sov ntxiv.
Yog tias xav tau kev kho cua sov rau cov yeeb nkab hlau kub tiav lawm, qhov kub kho cua sov yuav tsum siab dua1500°F [650°C].
Kev kho cua sov txhim kho qhov microstructure ntawm lub raj, txhim kho cov khoom siv kho tshuab, txhim kho kev tiv thaiv corrosion, txhim kho kev siv tshuab, ua kom muaj kev ruaj khov ntawm qhov ntev, thiab ua tau raws li qhov yuav tsum tau ua ntawm cov qauv tshwj xeeb, yog li ua rau kev ua tau zoo thiab kev haum ntawm lub raj zoo dua.
a Rau txhua qhov kev txo qis ntawm 0.01% qis dua qhov siab tshaj plaws ntawm cov pa roj carbon, kev nce ntawm 0.06% manganese saum toj no qhov siab tshaj plaws yuav raug tso cai txog li ntawm 1.35%.
b Tshwj tsis yog tias tus neeg yuav khoom tau teev tseg lwm yam, rau txhua qhov kev txo qis ntawm 0.01% qis dua qhov siab tshaj plaws ntawm cov pa roj carbon, kev nce ntawm 0.06% manganese saum toj no qhov siab tshaj plaws yuav raug tso cai txog li ntawm 1.65%.
cCr, Cu, Mo, Ni, thiab V yuav tsum tsis pub tshaj 1% ntawm tag nrho cov ntsiab lus ntawm tsib lub ntsiab lus no.
Qib A, B thiab Ctxawv nyob rau hauv lawv cov tshuaj lom neeg, feem ntau yog nyob rau hauv cov nqe lus ntawm carbon thiab manganese cov ntsiab lus.
Cov kev sib txawv no cuam tshuam rau cov khoom siv kho tshuab thiab cov xwm txheej siv ntawm cov raj. Cov pa roj carbon ntau dua, cov raj yuav muaj zog dua, tab sis qhov tawv yuav raug txo qis. Kev nce ntxiv ntawm cov manganese ua rau lub zog thiab qhov tawv ntawm cov hlau.
Cov Khoom Siv Tensile
AQhov tsawg kawg nkaus elongation hauv 2 nti [50 hli] yuav tsum txiav txim siab los ntawm cov qauv hauv qab no:
nti-phaus units:e = 625,000A0.2/UO.9
Cov chav nyob Sl:e = 1940A0.2/U0.9
e: qhov ntev tsawg kawg nkaus hauv 2 nti [50 hli], %, puag ncig mus rau qhov ze tshaj plaws 0.5%,
A: thaj tsam hla ntawm qhov qauv kuaj kev nruj, nyob rau hauv.2[hli2], raws li qhov ntsuas sab nraud lossis qhov dav ntawm cov qauv thiab qhov tuab ntawm phab ntsa uas tau teev tseg, puag ncig mus rau qhov ze tshaj plaws 0.01 hauv2[1 hli2].
(Yog tias thaj chaw uas suav tau yog sib npaug lossis loj dua 0.75 nti2[500 hli]2], ces tus nqi 0.75 nyob rau hauv2[500 hli]2] yuav tsum siv.),
U: lub zog tensile teev tseg, psi [MPa].
Kev Ntsuas Khoov
Rau cov kav dej DN 50 [NPS 2] thiab me dua, yuav tsum muaj qhov ntev txaus ntawm cov kav dej kom tso cai rau kev khoov txias ntawm cov kav dej los ntawm 90 ° yam tsis muaj kev tawg ib puag ncig lub mandrel cylindrical nrog txoj kab uas hla 12 npaug ntawm txoj kab uas hla sab nraud ntawm cov kav dej.
Rau OD > 25in. [635mm], yog tias OD/T ≤ 7, yuav tsum muaj kev sim khoov kom khoov 180° yam tsis tawg ntawm chav tsev kub. Lub cheeb sab hauv ntawm qhov khoov yog 1in.
Kev Ntsuas Kom Sib Nqus
ASTM A106 seamless steel yeeb nkab tsis tas yuav tsum tau kuaj xyuas kom tiaj tus, tab sis kev ua tau zoo ntawm cov yeeb nkab yuav tsum ua tau raws li qhov yuav tsum tau ua.
Tshwj tsis yog tias yuav tsum tau ua tshwj xeeb, txhua lub yeeb nkab yuav tsum tau kuaj xyuas hydro lossis kuaj hluav taws xob tsis ua rau puas tsuaj, thiab qee zaum ob qho tib si.
Yog tias tsis tau ua qhov kev sim hydrostatic lossis kev sim tsis ua puas tsuaj, cov yeeb nkab yuav tsum tau cim nrog "NH".
Kev Ntsuas Hydrostatic
Tus nqi ntawm lub zog dej yuav tsum tsis pub tsawg dua 60% ntawm qhov tsawg kawg nkaus ntawm lub zog tso zis.
Nws tuaj yeem suav los ntawm cov qauv hauv qab no:
P = 2St/D
P = hydrostatic test pressure hauv psi lossis MPa,
S = kev ntxhov siab ntawm phab ntsa yeeb nkab hauv psi lossis MPa,
t = teev tseg qhov tuab ntawm phab ntsa, teev tseg qhov tuab ntawm phab ntsa sib raug rau tus lej teem sijhawm ANSI teev tseg, lossis 1.143 npaug ntawm qhov tuab tsawg kawg nkaus ntawm phab ntsa, hauv. [mm],
D = txoj kab uas hla sab nraud uas tau teev tseg, txoj kab uas hla sab nraud uas sib raug rau qhov loj ntawm cov yeeb nkab ANSI uas tau teev tseg, lossis txoj kab uas hla sab nraud uas tau suav los ntawm kev ntxiv 2t (raws li tau txhais saum toj no) rau txoj kab uas hla sab hauv uas tau teev tseg, hauv. [mm].
Yog tias kev sim siab ntawm dej raug ua tiav, cov yeeb nkab hlau yuav tsum tau cim nrog lub cimkev sim siab.
Kev Ntsuas Hluav Taws Xob Tsis Muaj Kev puas tsuaj
Nws yuav siv tau ua lwm txoj hauv kev rau kev sim hydrostatic.
Tag nrho lub cev ntawm txhua lub yeeb nkab yuav tsum raug kuaj xyuas hluav taws xob uas tsis ua puas tsuaj raws liE213, E309, los yogE570cov lus qhia.
Yog tias kev sim tsis ua puas tsuaj tau ua tiav lawm, "NDE” yuav tsum tau qhia rau ntawm qhov chaw ntawm cov yeeb nkab.
Pawg neeg
Qhov hnyav tiag tiag ntawm cov yeeb nkab yuav tsum nyob rau hauv qhov ntau ntawm97.5% - 110%ntawm qhov hnyav teev tseg.
Txoj kab uas hla sab nraud
Qhov tuab
Qhov tuab ntawm phab ntsa tsawg kawg nkaus = 87.5% ntawm qhov tuab ntawm phab ntsa uas tau teev tseg.
Qhov ntev
Nws tuaj yeem raug cais ua pawgqhov ntev teev tseg, ib qho ntev random, thiabob chav ntev random.
Qhov ntev teev tseg: raws li qhov kev txiav txim xav tau.
Ib qho ntev random: 4.8-6.7 m [16-22ft].
