Txog Peb
Qhov Chaw Los Ntawm Cov Lus Qhia Txog Qhov Hnyav ntawm Cov Yeeb Nkab Carbon Steel
Cov qauv tseem ceeb rau qhov hnyav ntawm cov yeeb nkab carbon steel yog ISO 4200, EN 10220, ASME B36.10M, thiab ASTM A53/A53M.
Txawm hais tias tus qauv API 5L tsis muab cov lus qhia tshwj xeeb ntawm qhov hnyav ntawm cov yeeb nkab, cov lus sau rau Rooj 9 qhia tias cov nqi txheem rau qhov ntsuas sab nraud thiab phab ntsa tuab ntawm cov yeeb nkab hlau tau hais txog ISO 4200 thiab ASME B36.10M.
Piv Cov Qauv Qhov Hnyav ntawm Cov Yeeb Nkab Carbon Steel
Cov qauv sib txawv yuav muab cov lus qhia txog qhov hnyav tshwj xeeb rau cov ntawv thov sib txawv thiab cov hom khoom siv.
Txoj Kev Xam Qhov Hnyav ntawm Cov Yeeb Nkab
Txoj Kev Xam Qhov Hnyav ntawm Cov Yeeb Nkab Hlau muab ib txoj hauv kev yooj yim los xam qhov hnyav ntawm cov yeeb nkab hlau, ua rau nws muaj peev xwm txiav txim siab sai sai tag nrho qhov hnyav ntawm cov khoom siv xav tau, yog li txo cov nuj nqis tsis tsim nyog. Nrog txoj kev no, qhov hnyav ntawm cov yeeb nkab hlau tuaj yeem kwv yees raws li nws txoj kab uas hla, phab ntsa tuab, thiab ntev, uas yog qhov tseem ceeb heev rau kev npaj kev thauj mus los, tsim cov qauv txhawb nqa, thiab kwv yees cov nqi. Kev suav qhov hnyav raug kuj pab kom ntseeg tau tias muaj kev nyab xeeb ntawm cov qauv thiab tiv thaiv kev puas tsuaj ntawm cov qauv vim yog kev thauj khoom ntau dhau.
Cov mis hnyav rau cov yeeb nkab carbon steel yog qhov zoo ib yam hauv cov qauv sib txawv, tsuas yog muaj qhov sib txawv me ntsis hauv cov lus luv.
M=(DT) × T × C
Myog qhov hnyav ib chav ntev;
Dyog qhov txoj kab uas hla sab nraud uas tau teev tseg, qhia hauv millimeters (nti);
T yog qhov tuab ntawm phab ntsa uas tau teev tseg, qhia hauv millimeters (nti);
Cyog 0.0246615 rau kev suav hauv SI units thiab 10.69 rau kev suav hauv USC units.
LUS CEEV: API 5L muaj tus nqi ntawm 0.02466 hauv kev suav hauv SI units.
0.0246615 thiab 0.02466 sawv cev rau qhov sib txawv me me ntawm cov nqi uas tau siv hauv kev xam qhov hnyav. Qhov sib txawv no, txawm hais tias me me, tej zaum yuav muaj kev cuam tshuam thaum ua cov kev xam kom raug heev. Feem ntau, qhov sib txawv no yuav tsis muaj txiaj ntsig ntau rau feem ntau ntawm cov ntawv thov engineering thiab kev tsim kho, tab sis qhov twg xav tau qhov tseeb siab, tus nqi raug tsim nyog yuav tsum tau xaiv rau qhov xav tau tshwj xeeb.
Lub ntsiab lus ntawm Cov Yeeb Nkab Hlau
Nws yog ib qho kev suav lej uas siv los qhia qhov tuab ntawm phab ntsa ntawm cov kav hlau, muab ib qho kev siv sib xws rau qhov tuab ntawm cov kav kom haum rau ntau yam kev kub siab thiab kub.
Tshwj xeeb, tus lej "Schedule" siab dua, qhov tuab ntawm phab ntsa ntawm lub raj yuav tuab dua, thiab raws li qhov ntawd, qhov siab dua ntawm lub raj tuaj yeem tiv taus. Piv txwv li, Schedule 40 yog qhov nruab nrab phab ntsa tuab uas siv dav hauv cov ntawv thov qis mus rau nruab nrab, thaum Schedule 80 muaj phab ntsa tuab dua rau cov chaw muaj siab dua.
Qhov kev faib tawm no tau tsim thawj zaug los ua kom yooj yim rau cov txheej txheem ntawm kev tsim thiab tsim cov kav dej lag luam los ntawm kev ua kom cov qib tuab ntawm phab ntsa zoo ib yam, ua rau nws yooj yim dua rau cov engineers xaiv cov kav dej kom raug rau lawv qhov chaw ua haujlwm. Cov qib sib txawv ntawm Schedule tau tsim los ntawm kev xav txog ntau yam, suav nrog cov khoom siv kho tshuab ntawm cov ntaub ntawv siv, qhov siab thiab kub nyob rau hauv cov xwm txheej ua haujlwm, thiab qhov xwm txheej ntawm cov kua dej.
Cov Ntaub Ntawv Teev Sijhawm Cov Yeeb Nkab Carbon Steel
Hauv Cov Yeeb Nkab Schedule ASME B36.10 thiab ASTM A53 Rooj 2.2 (Plain End) uas yog, tus nqi yog tib yam.
Txawm li cas los xij, vim muaj qhov sib txawv ntawm kev ua cov yeeb nkab kawg ASTM A53 Rooj 2.3 (Xov thiab Txuas) cov nqi yuav txawv.
ASTM A53 Rooj 2.3 (Xov thiab Txuas) Daim Ntawv Teev Npe 30, 40, 60, thiab 80 xwb. Hauv cov lus nug ntawm Daim Ntawv Teev Npe Yeeb Nkab, xyuam xim rau Qhov Txawv.
Kev Faib Tawm Lub Sijhawm
teem sijhawm 5, teem sijhawm 10, teem sijhawm 20, teem sijhawm 30, teem sijhawm 40, teem sijhawm 60, teem sijhawm 80, teem sijhawm 100, teem sijhawm 120, teem sijhawm 140, teem sijhawm 160.
Cov Qauv 40 thiab Cov Qauv 80 yog cov qib tuab phab ntsa yeeb nkab feem ntau rau cov chaw muaj siab qis mus rau nruab nrab thiab cov chaw muaj siab dua, raws li.
