ASTM A335 P9 Seamless Yeeb Nkab - 9Cr-1Mo Chrome Moly Yeeb Nkab
Xi'an Dongmeng Group Co., Ltd.khoom sivASTM A335 P9 / ASME SA335 P9 seamless chrome moly yeeb nkabrau refinery, petrochemical, siab -kub txheej txheem piping thiab lwm yam siab-piping daim ntaub ntawv yuav tsum tau ib tug ferritic chromium-molybdenum alloy steel.
ASTM A335 P9 yog a9Cr-1Mo tsev neeg seamless alloy steel yeeb nkab, muaj kwv yees li8.00-10.00% chromium thiab 0.90-1.10% molybdenumraws li cov khoom siv specification.
Piv nrog rau qis -chromium qib xws li P5, P11 thiab P22, P9 muaj ntau ntau chromium thiab feem ntau teev nyob rau hauv refinery thiab siab -kub txheej txheem piping systems qhov project piping class hu rau 9Cr-1Mo cov khoom.
P9 yuav tsum tsis txhob totaub nrog ASTM A335 P91. Txawm hais tias ob leeg muaj kwv yees li 9% chromium alloy tsev neeg,P9 yog cov pa 9Cr-1Mo steel, thaum P91 yog ib qho kev hloov kho creep-lub zog- txhim kho ferritic hlau uas muaj cov khoom siv tshuaj tiv thaiv ntxiv thiab yuav tsum tau ua kom muaj cua sov sib txawv- kev kho thiab kev tsim khoom.
Dongmeng Group tuaj yeem muab P9 seamless yeeb nkab raws li qhov xav tauNPS lossis OD, phab ntsa tuab lossis Teem sijhawm, qhov ntev, kev npaj kawg, cua sov-kev kho mob, qib tshuaj xyuas thiab cov ntaub ntawv tsim nyog.
ASTM A335 P9 yeeb nkab yog dab tsi?
ASTM A335 / A335M npogseamless ferritic alloy- steel yeeb nkab npaj rau siab -kev pabcuam kub.
P9 yog ib qho ntawm cov chromium- qib molybdenum suav nrog hauv cov lus qhia no.
Cov txheej txheem yog npaj rau cov yeeb nkab haum rau kev ua haujlwm xws li khoov, flanging thiab fusion vuam, raws li cov txheej txheem engineering thiab fabrication.
Kev xaiv cov khoom yuav tsum tsis txhob ua raws li lub npe alloy ib leeg.
Qib yeeb nkab tsim nyog nyob ntawm:

P9 yog kwv yees li ntawm 9Cr-1Mo tsev neeg.
Lawv cov chemistry thiab engineering daim ntawv thov sib txawv, thiab kev hloov pauv yuav tsum xav tau qhov kev pom zoo.
7. Lub zog tensile ntawm ASTM A335 P9 yog dab tsi?
Qhov tsawg kawg nkaus tensile lub zog yog kwv yees li415 MPa / 60 ksiRaws li cov kev cai ASTM A335.
8. Qhov tsawg kawg nkaus tawm lub zog ntawm P9 yog dab tsi?
Qhov tsawg kawg nkaus qhov kev tawm dag zog yog kwv yees li205 MPa / 30 ksi.
9. Kev kho cua sov yog siv rau P9 li cas?
ASTM A335 P9 tej zaum yuav muab siv tag nrho annealing, isothermal annealing, los yog normalizing thiab tempering raws li cov specifications.
10. Puas yog P9 yeeb nkab xav tau PWHT tom qab vuam?
PWHT qhov yuav tsum tau nyob ntawm qhov kev tsim kho, phab ntsa tuab, txheej txheem vuam, kev pabcuam thiab qhov project specification.
Lawv yuav tsum tau txhais los ntawm cov txheej txheem vuam tsim nyog es tsis yog los ntawm qhov ntsuas kub thoob ntiaj teb luam tawm ntawm nplooj ntawv muag.
11. Koj puas tuaj yeem muab PMI rau P9 yeeb nkab?
Yog lawm. PMI tuaj yeem raug teev los txheeb xyuas tus kheej ntawm alloy, tshwj xeeb tshaj yog rau cov haujlwm uas muaj ntau yam Cr-Mo qib.
12. ASTM A335 P9 puas tuaj yeem muab EN 10204 3.1 ntawv pov thawj?
EN 10204 3.1 cov ntaub ntawv tuaj yeem npaj tau qhov uas suav nrog hauv qhov yuav tsum tau yuav thiab txhawb nqa los ntawm cov khoom xaj.
13. Qhov luaj li cas muaj?
P9 tuaj yeem muab tau rau hauv ntau yam ntawm NPS, cov sijhawm teem sijhawm thiab phab ntsa tuab nyob ntawm lub peev xwm zeb thiab kev txiav txim kom muaj nuj nqis.
Xa qhov xav tauNPS / OD + phab ntsa / Teem sijhawm + ntev + ntaurau kev lees paub muaj.
14. Puas yog P9 stainless hlau?
Tsis muaj.
Txawm hais tias nws cov ntsiab lus chromium kuj siab, P9 yog ferritic Cr-Mo alloy steel nyob rau hauv ASTM A335 thiab yuav tsum tsis txhob ua lag luam li stainless hlau.
15. Puas yog P9 haum rau kev pabcuam hydrogen?
P9 yog siv nyob rau hauv refinery thiab txheej txheem daim ntawv thov, tab sis tsim nyog rau ib tug tshwj xeeb hydrogen - muaj kev pab cuam tsis tuaj yeem txiav txim siab los ntawm qib npe ib leeg.
Tus tsim yuav tsum xav txog qhov kub thiab txias, hydrogen ib nrab siab, degradation mechanisms thiab siv qhov project engineering xav tau.
