Hais txog ntawm ASME B36.10 tus qauv (seamless thiab welded carbon thiab alloy steel yeeb nkab)
1. Q: Dab tsi ntawm cov yeeb nkab steel twg puas yog li cas?
A: • Nws siv rau seamless thiab welded carbon thiab alloy steel yeeb nkab (tsis suav nrog cov hlau stainless, uas yog them los ntawm ASME B36.19).
• Nws yog feem ntau siv nyob rau hauv high - kub thiab siab {-}} pa, tshuaj, thiab fais fab nroj tshuag piping tshuab.
Cov ntaub ntawv ntxiv: tus qauv tshwj xeeb hais txog qhov ntev, cov tes taw hnyav, thiab thev taus rau cov kav dej steel los ntawm cov yeeb nkab nominal
2
A: • NPS: Tus xov tooj sawv cev kwv yees kwv yees li ntawm nti (piv txwv li, nps 2 sawv cev rau sab nraud ntawm kwv yees li 2 nti). Txawm li cas los xij, rau NPS 14 lossis siab dua, sab nraud ntawm txoj kab uas muaj sib npaug (piv txwv li, npe, sawv cev rau sab nraud ntawm 14 nti).
• Teem caij: Qhia txog cov qib tuab ntawm phab ntsa tuab (piv txwv li School 40, SchE 80). Ib tus lej ntau dua qhia tias tuab tuab phab ntsa tuab thiab siab dua tsis kam.
Ntxiv Nco Ntsoov Ntxiv: Sch 40 thiab Sch 80 yog cov qhab nia kawm, tab sis thov nco ntsoov tias Phab Ntsa Thickness tiag tiag ntawm tib lub sijhawm nyob rau hauv Npss sib txawv yuav txawv.
3. Q: Dab tsi yog qhov sib txawv ntawm ASME B36.10 thiab B36.19?
A: • B36.10: Rau cov hlau thiab aluminium hlau thiab alloy steel kav, haum rau high-- qhov kev siv siab.
• B36.19: Tshwj xeeb rau cov kav dej stainless hlau, nrog kev sib txawv me me thiab kev tso siab rau qhov yuav tsum tau ua.
Cov Ntsiab Lus Tseem Ceeb: ob lub npe Nps thiab cov sijhawm sib xws, tab sis cov khoom muaj kuab lom thiab cov khoom siv steel txawv ntev ntev teev?
A: • Txiav ntev: Feem ntau 6 metres (20 tshim) lossis 12 nti (40 ko taw), nrog kev sib txawv ntawm **} mm / -0 mm **.
• Random ntev: Feem ntau 4-9 meters, nyob ntawm cov ntawv pom zoo chaw nres tsheb.
Lus Ceeb Toom Ntxiv: Cov Kev Xav Tau Tshwj Xeeb (xws li Submarine Pipelines) yuav xav tau kev ua kom nruj.
5. Q: Dab tsi yog cov qauv uas yuav tsum tau ua rau cov yeeb nkab steel?
A: • Lub meej kawg (PE): Haum rau vuam lossis flange sib txuas.
• Threaded kawg (te): yuav tsum ua raws li ASME B1.20.1 xov cov qauv.
• Beveled Kawg (yuav): Rau siab - pa siab vuam, lub bevel kaum yog feem ntau 30℃± 12℃± 12℃± 20℃±
Nco tseg: Lub hom kawg yuav tsum tau hais meej meej hauv qhov kev txiav txim kom paub tseeb tias tau txais.
