EN10210 Cov Kav Hlau Tsis Muaj Qhov TxuasIb Phau Ntawv Qhia Txog Kev Yuav Khoom Siv Rau Kev Tsim Kho Vaj Tse. Thaum nrhiav cov seem khoob rau kev tsim kho, choj, lossis kev tsim kho tshuab,EN10210 tus qauvyog qhov tseem ceeb rau feem ntau ntawm cov haujlwm European thiab thoob ntiaj teb. Kev nkag siab txog qhov sib txawv ntawm cov lus qhia no yog qhov tseem ceeb rau cov thawj coj kev yuav khoom thiab cov engineers kom tsis txhob muaj lub sijhawm tsis ua haujlwm kim, kev tsis sib haum xeeb zoo, thiab kev ncua sijhawm ntawm qhov project. Phau ntawv qhia no npog txhua yam koj xav paub txog EN10210 seamless steel pipes, los ntawm cov tshuaj lom neeg sib xyaw mus rau cov xwm txheej xa khoom thiab cov txheej txheem tshuaj xyuas.
1. EN10210 yog dab tsi? (Cov Ntsiab Lus Tseem Ceeb)
EN10210-1 thiab EN10210-2 txhais cov xwm txheej kev xa khoom rau cov khoom kub-ua tiav cov qauv hollow ua los ntawm cov hlau tsis yog alloy thiab cov hlau zoo. Tsis zoo li EN10219 (ua txias), EN10210 npog cov khoom kub-ua tiav. Cov txheej txheem kub-ua tiav (normalizing lossis normalizing dov) txo cov kev ntxhov siab sab hauv, yog li txhim kho weldability thiab xyuas kom meej ntau dua cov khoom siv kho tshuab thoob plaws phab ntsa tuab.
2. Cov Qib Hlau Tseem Ceeb raws li EN10210 Tus Qauv
Kev xaiv qib hlau zoo yog thawj kauj ruam mus rau kev yuav khoom zoo. Tus qauv no suav nrog ntau qib, faib ua pawg los ntawm lub zog tso zis thiab kev cuam tshuam tawv:
S235JRH: Cov hlau qauv yooj yim, tsim nyog rau qhov kub thiab txias ib puag ncig.
S275J0H / S275J2H: Muaj zog dua, feem ntau siv rau hauv kev tsim kho dav dav.
S355J0H/ S355J2H / S355K2H: Cov qib siv dav tshaj plaws rau cov qauv hnyav.
E275 / E355 (Cov noob zoo): Muaj kev ua tau zoo dua hauv qhov kub qis.
Cov Lus Qhia Tseem Ceeb Txog Kev Yuav Khoom: Ib txwm xyuas kom meej qhov kub ntawm qhov kev sim cuam tshuam. "J0" qhia txog 0 ° C, "J2" qhia txog -20 ° C, thiab "K2" qhia txog -20 ° C tab sis nrog kev nqus hluav taws xob ntau dua (40J vs. 27J). Rau cov haujlwm hauv Northern Europe lossis thaj chaw huab cua txias, kev siv S355J2H lossis S355K2H yog qhov yuav tsum tau ua.
3. Kev kam rau siab thiab qhov ntev (Cov ntsiab lus yuav tsum tau kuaj xyuas)
Qhov kev kam rau siab ntawm qhov ntev raws li tus qauv EN 10210 yog nruj dua li cov uas nyob hauv tus qauv ASTM. Thaum tso ib qho kev txiav txim, thov nco ntsoov:
Kev kam rau sab nraud (OD): Feem ntau ± 1% rau cov khoom kub tiav, tab sis ib txwm xyuas cov lus qhia tshwj xeeb hauv tus qauv.
Kev kam rau phab ntsa tuab: Tsis zoo li cov raj txias uas tsim, cov raj kub tiav lawm muaj kev kam rau tsis zoo; qhov no yuav tsum tau suav nrog hauv cov lus qhia engineering.
Kev kam rau siab ntawm qhov hnyav (qhov hnyav): Xyuas kom tus neeg muag khoom lav qhov sib txawv ntawm qhov hnyav theoretical thiab qhov hnyav tiag tiag (feem ntau yog nyob hauv ± 6%).
Lub Tswv Yim Rau Tus Neeg Yuav Khoom: Yog tias koj xav tau "kev kam rau siab zoo" ntawm phab ntsa tuab kom ntseeg tau tias muaj kev nyab xeeb thaum lub sijhawm kuaj hydrostatic siab, thov qhia qhov no kom meej.
4. Kev Xa Khoom thiab Kev Kho Mob Kub
Tus "H" nyob rau hauv qib kev xaiv (piv txwv li, S355J2H) qhia txog kev kho cua sov. Feem ntau, qhov no txhais tau tias:
Kev dov ib txwm muaj (N)
Kev tsim kho kom zoo li qub (N)
Kev kho cua sov no ua kom cov qauv ntawm cov noob zoo nkauj dua. Ib txwm thov daim ntawv pov thawj kuaj xyuas zeb (MTC)—Hom 3.1 lossis 3.2 raws li EN 10204—kom paub tseeb tias qhov kub thiab txias thiab lub sijhawm tuav tau raws li qhov yuav tsum tau ua.
5. Daim Ntawv Teev Cov Khoom Yuav Khoom: 5 Lub Ntsiab Lus Tseem Ceeb Ua Ntej Kos Npe Rau Daim Ntawv Yuav Khoom.
A. Qhov Zoo Ntawm Qhov Chaw & Qhov Tsis Zoo Sab Hauv
EN10210 hais tias qhov chaw yuav tsum tsis muaj kab nrib pleb, qhov chaw puag ncig, thiab qhov nplai. Txawm li cas los xij, qhov tsis zoo me me ntawm qhov chaw raug tso cai yog tias lawv tseem nyob hauv qhov kev kam rau siab tsis zoo.
Cov Lus Qhia:Sib tham txog qhov "txwv tsis pub muab pov tseg" rau qhov tsis zoo ntawm qhov chaw hauv koj daim ntawv cog lus. Xav kom muaj kev tshuaj xyuas pom 100% ntxiv rau NDT (Kev Ntsuas Tsis Ua Rau Puas Tsuaj) rau cov ntawv thov tseem ceeb.
B. Cov Tshuaj Lom Zem & CEV (Carbon Equivalent Value)
Rau cov ntawv thov vuam uas siv ntau, tus nqi Carbon Equivalent Value (CEV) tseem ceeb dua li cov ntsiab lus carbon xwb.
EN10210 txwv CEV kom ntseeg tau tias muaj kev vuam zoo. Rau qib S355, CEV feem ntau nyob ≤ 0.45.
Kev Ua:Thov tus neeg muag khoom muab cov ntaub ntawv tshuaj xyuas lub ladle tiag tiag, tsis yog tsuas yog cov nqi uas lub hom phiaj xav tau xwb.
C. Kev Ntsuas Tshuab
Xyuas kom tseeb tias cov kev ntsuam xyuas hauv qab no suav nrog rau hauv kev khiav ntau lawm:
Kev Ntsuas Tensile (Lub zog tawm los, UTS, Elongation%)
Kev Ntsuas Kev Cuam Tshuam (Charpy V-notch ntawm qhov kub thiab txias teev tseg)
Kev Ntsuas Flattening (los xyuas qhov ductility)
Kev Ntsuas Hydrostatic (yog tias xav tau rau kev siv siab, txawm hais tias EN10210 yog qhov tseem ceeb ntawm cov qauv, lees paub qhov no cais).
D. Kev Xaus thiab Kev Tiv Thaiv
Cov Qhov Kawg Beveled: Rau kev vuam, thov cov qhov kawg API-style bevel (30° +/- 5°) nrog thaj av ntawm 1.6mm.
Cov Hau Kawg: Ib txwm thov cov hau kawg yas kom tiv thaiv cov xov thiab qhov ntawm cov dej noo thaum lub sijhawm thauj khoom hauv hiav txwv.
E. Kev taug qab tau
Txhua lub yeeb nkab yuav tsum tau cim kom meej meej nrog lub logo ntawm tus neeg tsim khoom, tus qauv (EN10210), qib, qhov loj me, thiab tus lej cua sov.
Txoj Cai Tseem Ceeb: Tsis txhob muab cov khoom siv uas cov cim xim-stencil nyeem tsis tau; qhov no yog lub cim liab rau kev tswj xyuas zoo tsis zoo.
6. Tej Yam Uas Yuav Tsum Tau Ua Hauv Kev Yuav Khoom EN10210
Kev tsis meej pem EN10210 nrog EN10219: Lawv TSIS tuaj yeem hloov pauv tau. EN10219 (ua los ntawm txias) muaj lub zog tso zis siab dua vim yog ua haujlwm txias tab sis qis dua ductility thiab siab dua residual stress.
Tsis Kwv Yees Qhov Cuam Tshuam ntawm Kev Ua Kub-Ua Kom Tiav: Tus nqi ntawm EN10210 feem ntau yog 8-15% siab dua li kev ua txias. Tsis txhob txo qhov cuam tshuam yog tias koj tus qauv tsim xav tau kev txo kev ntxhov siab tom qab vuam.
Tsis Txhob Xav Txog Qhov Ntev Uas Yuav Tsum Tau Ua: EN10210 muaj peb pawg ntev. Yog tias koj xav tau qhov ntev uas tsis tas yuav txiav kom txuag tau cov nqi pov tseg, thov sau "Qhov Ntev Tseeb" rau hauv qab no.
7. Cov Lus Qhia Txog Ib Puag Ncig & Kev Ua Raws Cai
Raws li cov kev hloov tshiab tsis ntev los no, xyuas kom koj tus neeg muag khoom ua raws li REACH thiab RoHS cov cai yog tias xa khoom mus rau EU. Tsis tas li ntawd, xyuas kom meej tias cov txheej txheem ua hlau ua raws li cov qauv ntawm Sustainable Development Goals (SDG) - qhov no tab tom dhau los ua qhov yuav tsum tau ua rau tsoomfwv cov kev sib tw tsim kho vaj tse.
ua raws li qhov kam rau ua raws li tau teev tseg hauv Rooj 3 ntawm EN10210-2.
