Kev sib piv ntawm cov khoom lag luam ntsuas qhov tseem ceeb ntawm cov ntaub ntawv hauv tsev thiab WPB cov qauv txiaj ntsig
Txawm hais tias los ntawm tus qauv kev xav, nws zoo li tias cov ntaub ntawv hauv tsev tsis tuaj yeem hloov qee qhov kev txiav txim siab nrog cov khoom siv ntawm cov khoom siv hauv tsev. Los ntawm kev tshawb xyuas yav dhau los, muaj ob yam tseem ceeb uas cuam tshuam rau kev tsim tsa hloov chaw:
Qhov teeb meem ntawm Si cov ntsiab lus hauv Q Series Hlau Hlau;
⑵ Txhua cov khoom ua lag luam hauv tsev tsim qauv yog qis dua tus qauv uas yuav tsum tau ua WPB.
Los ntawm kev sib piv rooj 3 thiab cov lus 4, peb pom tau tias:
Qhov tseeb cov khoom siv ntawm SI cov ntsiab lus hauv q series steel daim hlau yog nruab nrab ntawm {{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}.}.}
⑵ Cov Ntaub Ntawv Hauv Tsev
Qhov tseeb tiag cov txiaj ntsig ntawm kev ua tau zoo rau 2 {}} mpa, thiab 20%}}}}}} ntawm cov ntaub ntawv nyoos), thiab tag nrho cov kev ua tau zoo index qhov tseem ceeb ntawm tus lej sib tw ua kom tau raws li cov qauv WPB; ⑶ Qhov tseeb cov khoom siv ntawm cov ntsuas kev ua tau zoo Q235A thiab Q235B states tau tsawg dua 410} dua li WPB yuav tsum tau), nyiaj txiag rau 0.8% ntawm tag nrho cov cua sov; Ys yog 255-360 MPa, uas ua tau raws li qhov yuav tsum tau ua ntawm WPB; Elongation el yog 25% {15}}%, uas ua tau raws li kev yuav tsum tau ntawm WPB; HB yog 140-170 (raws li cov ntsuas hluav taws xob tiag, lub cev tawv ntawm cov yeeb nkab fittings yog ib qho uas yog cov ntaub ntawv nyoos), uas ua tau raws li cov cai ntawm WPB.

Los ntawm kev sib piv cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv tshuab ntawm Actionically cov paib thiab GB} Qhov kev sib tw ntawm WPB pom tias nyob rau hauv thaj chaw cua sov Batches, 100% ntawm domassically profuced carbon hlau seamless steel kav yuav ua tau zoo nrog astma234gr wpb qhov yuav tsum tau; Ntau tshaj 99% ntawm kev ua lag luam carbon hlau hauv khw tuaj yeem ua tau raws li Astma234Gr WPB cov cai. Los ntawm xaiv tswj cov muaj pes tsawg leeg thiab kev ua tau zoo ntawm cov khoom siv raw, kev siv cov khoom siv steel hlau tuaj yeem ntsib A234Gr WPB yuav tsum tau ua.
ASTM A234 carbon cov hlau yeeb nkab luj lub luj tshib yog qhov dav dav rau lawv txoj kev yooj yim. 90 degree thiab 45 degree luj yog txheem lauj kaub, tab sis lwm cov ces kaum lossis khoov tau kuj tseem tuaj yeem tsim los ntawm kev txiav lawv cov ces kaum sib txawv.
Ob tug khoov nrog cov hluav taws xob sib txawv kuj tau siv, uas yog lub vojvoog luv luv thiab ntev vojvoog. Txoj kab uas hla ntawm lub vojvoog Luv Luj Tshib yog 1, thaum txoj kab uas hla ntawm lub vojvoog ntev ntev yog 1.5d.
