Dub Carbon Hlau Yeeb Nkab DN800

Tsim Tsim: Tus Thawj Tsav Tsheb Ntawm Cov Sij Hawm Xaiv

Kev Tsim Kho Siab Hais txog qhov siab tshaj plaws lub raj mis yuav tsum tau tiv thaiv lub sijhawm ua haujlwm xws li pib hloov pauv thiab kaw). Nws txiav txim ncaj qha rau cov phab ntsa uas yuav tsum tau ntawm cov yeeb nkab: qhov tsim qauv siab, cov tuab ntawm phab ntsa, thiab yog li lub sijhawm kawm qib siab dua.

Kev sib raug zoo ntawm kev tsim qauv siab thiab phab ntsa thickness ua raws covBarlow Tus Qauv, ib qho tseem ceeb muab cov cuab yeej hauv cov yeeb nkab engineering:

T = (P × D) / (2 × S × E)

Qhov twg:

T{{0 {}} Yam tsawg kawg nkaus uas yuav tsum tau muaj phab ntsa tuab (hli)

P= Tsim Kev Siab (Mpa)

D{{0 {}} sab nraud ntawm txoj kab ntawm cov yeeb nkab (hli)

S=} Muab cov yeeb yam yooj yim ntawm cov yeeb nkab cov khoom (MPA, txiav txim siab los ntawm cov khoom hom thiab kev ua haujlwm los ntawm cov hom khoom thiab kev ua haujlwm los ntawm cov khoom kub)

E= weld effleciency (cuam tshuam rau cov txheej txheem vuam, piv txwv li 0.85 rau erw, 0.9 rau hfw)

Piv txwv li, cov pa roj carbon steel (s=110 MPA yuav tsum tau ib phab ntsa tuab ntawm 1,5mm, txuam Daws Hack.

HUAYANG STEEL YEEB QIM NYOG RAU VIM LI CAS RAU VAJ LUB HLI NTAU LAWM. Rau cov hluav taws xob tiv thaiv welded steel yeeb nkab (ERW) Siv Hauv Kev Siv Hauv Nroog (Tsim Nyog 0.8-1.2 GRA) Rau HFW Steel Yeeb Nkab Siv hauv cov roj thiab roj kev sib kis (Tsim Nyog 8-12 MPA, kom paub meej txhua yam khoom tau ua tiav.

Nominal Dev (Nps): Ntsuas Thickness thiab Kev Ntseeg

Nominal Dev (NPS, NPS, NPS 2, NPS 8) yog ib qho loj dua sawv cev cov yeeb nkab kwv yees sab hauv, tsis yog nws lub taub sab hauv. Nws cuam tshuam sijhawm teem sijhawm qib qib los ntawm kev cuam tshuam cov yeeb nkab cov qauv ruaj khov thiab khoom siv siv khoom:

Me - txoj hauj lwm hla (nps 1-4): Vim yog lawv cov txheej txheem me me, txawm yog cov menyuam kawm qib qis, sch 20, sch 40) muaj phab ntsa txaus kom tiv thaiv lub siab. Piv txwv li, NPS 2 tus yeeb nkab muaj cov phab ntsa tuab ntawm 3.91 hli, uas tuaj yeem tiv taus rau 1.6 MPA siab rau cov hlau.

Nruab nrab - txoj hauj lwm hla (NPS 6-12): Raws li txoj kab uas cov taub tau nce, tib lub siab yuav tsum muaj lub phab ntsa tuab kom tsis txhob deformation. Yog li, nruab nrab {- txoj hauj lwm uas hla tshaj plaws siv tus sch 40-sch 80 qib.

Loj - txoj hauj lwm uas hla hla (NPS 14-24): Loj {- txoj kab uas hla txoj kab uas hla tau zoo li khoov thiab siab-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} ua rau nthuav dav. Cov Sijhawm Kawm Qeb Siab (SCH 80, SCH 120) feem ntau siv los txhim kho cov qauv muaj zog. Piv txwv li, NPS 16 SCH 120 yeeb nkab muaj lub phab ntsa tuab ntawm 15.88mm, haum rau high {9} kub roj kev kis tau.

Huayang Steel yeeb nkab Txhim kho ntau lawm ntau lawm los ntawm NPS thiab caij nyoog kawm qib. Rau me - diam zog hluav taws xob welding, sib txuas cov ntsiab lus ua kom zoo nkauj (NPRE 1-4), nws siv sch 20-sch 40 qib; Rau loj- didw steel yeeb (NPS 140 Qib 160, kev ntsuas ntau lawm thiab cov khoom lag luam.
