{{0 {}} hom phiaj thiab kev pov hwm
Lub hom phiaj ntawm cov kev tshwj xeeb no yog muab cov qauv rau kev siv hauv cov roj, dej, thiab roj av hauv ob {}}
Qhov no qhia txog qhov no tau npog seamless thiab welded steel kab yeeb {}}} nws muaj cov yeeb nkab npaj rau kev siv nrog cov kev pab tshwj xeeb npaj rau kev siv nrog cov kev pabcuam tshwj xeeb.
Txawm hais tias lub tiaj-kawg kab sib ntsib cov kab sib ntsib no yog feem ntau npaj rau kev pleev tshuaj pleev duab kos duab los ntawm kev siv vuam muag los ntawm kev ua haujlwm ntawm kev ua haujlwm vuam .
2. cov khoom lag luam qib tshwj xeeb (PSL)
Cov kev qhia tshwj xeeb no tau tsim rau ob theem kev cai tshwj xeeb (PSL I.}}}}}}}}}}}}}}}}}}} 1.
Cov kev xav tau uas siv rau tsuas yog PSL I lossis tsuas yog sau ntawv rau cov ntawv sau tshwj xeeb rau ob qho tib si psl siv rau ob qho tib si psl i thiab psl 2.
Tus neeg yuav khoom yuav ntxiv cov kev txiav txim los yuav cov ntawv xaj rau psl Kuv lossis PSL 2, raws li cov kev xaiv ntxiv (ntxiv rau (4 {{3 thiab 4.3).
3. qib
Cov qhab nia (saib cov ntawv sau tseg) them los ntawm qhov kev qhia tshwj xeeb yog cov txheem qib A25, X42, x56, X 105, X70 thiab X 10; thiab cov qib theem nrab (cov qib uas siab dua X42, nruab nrab rau ob qho kev lag luam thiab kev pom zoo los ntawm tus neeg yuav khoom thiab chaw tsim khoom).
PSL Kuv cov yeeb nkab tuaj yeem muab rau hauv cov qhab nia A25 los ntawm x 70.
Psl 2 yeeb nkab tuaj yeem muab rau hauv qib b los ntawm x 80.
Chav kawm II (CI II) steel yog rephosphorized thiab tej zaum muaj xov zoo dua li chav kawm uas kuv kawm (ci), nws yuav nyuaj dua li khoov .
Yeeb nkab tsim ua qib X60 lossis siab dua yuav tsum tsis txhob hloov chaw rau cov yeeb nkab xaj raws li qib X52 lossis qis dua yog tsis muaj cov neeg yuav khoom thov {2}
Note: The grade designations are dimensionless. Grades A and B do not include reference to the specified minimum yield strength; Txawm li cas los xij, lwm cov kev kawm yog tsim los ntawm thawj ob tus lej ntawm qhov tshwj xeeb tawm los lub zog hauv koj lub zog}}} kev cai {}}
4. qhov ntev
Qhov ntau thiab tsawg no siv ntawm no yog qhov chaw nyob ruaj khov, uas tau muab los ntawm cov cheeb tsam sab nraud raws li ntsuas ntawm koj ntsuas, thiab muab a
yooj yim txoj kev ntawm cov yeeb nkab loj hauv cov ntawv nyeem thiab cov ntxhuav (tab sis
Tsis yog rau kev txiav txim cov lus piav qhia) {{{. cov yeeb nkab ntau thiab tsawg thib 23/8 thiab loj dua yog qhia raws li cov lej thiab cov zauv feem; Yeeb nkab loj dua 23/8 yog qhia rau peb qhov ntau thiab tsawg yog thov kom paub lawv tus kheej rau cov kev qhia loj no tau siv hauv qhov kev qhia loj no, Tshwj xeeb tshaj yog cov kev siv nyob hauv cov rooj 4, 5, thiab 6A .
Psl i cov yeeb nkab tuaj yeem muab rau hauv qhov ntau thiab tsawg nyob ntawm 0.405 los ntawm 80.
Psl 2 yeeb nkab tuaj yeem tsim cov khoom seem ntawm 4 '/ 2 los ntawm 80.
Cov kev xav tau ntawm cov lus thiab xov cov kev coj ua, cov qauv kev soj ntsuam, nrog rau cov khoom lag luam hauv API
