Qhov txawv tseem ceeb: txawv phab ntsa thickness
Yuav kom nkag siab qhov txawv, peb yuav tsum xub qhia meej tias "K" tiag tiag sawv cev. Ntau tus neeg ntseeg yuam kev tias K7, K8, thiab K9 yog cov yeeb nkab qauv, tab sis qhov no tsis yog qhov teeb meem. Ntawm no, "K" sawv cev rau phab ntsa thickness coefficient, muab los ntawm lub teb chaws tus qauv GB / T 13295-2019. Cov txheej txheem phab ntsa thickness yog suav nrog cov qauv e=K × (0.5+0.001 × DN). Qhov loj dua tus nqi K, qhov tuab ntawm cov yeeb nkab phab ntsa thiab qhov muaj zog dua nws lub peev xwm-kev coj tus kheej.
Siv DN800 yeeb nkab ua piv txwv, phab ntsa tuab ntawm K7 yog kwv yees li 9.1 hli, thaum K9 yog kwv yees li 11.7 hli. Qhov ncaj qha tshwm sim ntawm qhov sib txawv ntawm phab ntsa thickness yog ib qho kev nce qib hauv siab -cov kabmob muaj peev xwm:
▶ K7 qib ductile hlau yeeb nkab: tuaj yeem tiv taus cov raj xa dej siab hauv qab 1.0MPa, qhov muaj peev xwm qis tshaj plaws ntawm peb qib, uas yog cov ntawv siv siab tsawg -.
▶ K8 qib ductile hlau yeeb nkab: tuaj yeem tiv taus cov kav dej hauv qab 1.25MPa, nrog lub peev xwm siab ntawm K7 thiab K9, haum rau nruab nrab - cov xwm txheej siab.
▶ K9 qib ductile hlau yeeb nkab: tuaj yeem tiv taus cov raj xa dej siab tshaj 1.6MPa, nrog lub peev xwm siab tshaj plaws, yog thawj qhov kev xaiv rau cov kav dej hauv nroog loj.
▶ qib K9 thiab siab dua cov yeeb nkab hlau: xws li K10, K11, K12, thiab lwm yam, nrog lub peev xwm siab dua li K9, thiab tuaj yeem hloov kho raws li daim ntawv thov scenario.
Daim ntawv thov scenarios: Hom phiaj xwm twg nws tsim nyog rau?
Peb theem muaj lub luag haujlwm sib txawv hauv engineering vim lawv qhov sib txawv siab- muaj peev xwm muaj peev xwm.
Qib K7 – Kev xaiv nyiaj txiag rau qis-Cov ntawv thov kev nias.K7 qib ductile hlau kav muaj cov phab ntsa nyias thiab cov nqi qis dua, ua rau lawv tsim nyog rau cov haujlwm uas xav tau qis dua, xws li cov dej hauv tsev thiab cov dej hauv cov zej zog zoo tib yam, qis - cov kav dej siab hauv cov chaw ua si, thiab cov kav dej me me. Lawv qhov kev sib koom ua ke yooj yim tsim tau zoo absorbs lub hauv paus kev daws teeb meem kev ntxhov siab, txo qhov kev pheej hmoo ntawm to.
K8 Qib - Tus Nqi -Kev Xaiv Zoo, haum rau cov xwm txheej siab nruab nrab. K8 qib kav dej muaj qhov nruab nrab ntawm phab ntsa tuab thiab kev ua haujlwm siab dua piv rau K7, muab qhov sib npaug zoo ntawm tus nqi thiab kev ua haujlwm. Lawv tau siv dav hauv cov kav dej hauv nroog hauv nroog, cov chaw tsim khoom me me, thiab hauv cov kav dej txuas ntxiv ntawm ntau-cov tsev nyob, K8 kav kuj tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg nyob hauv txhua hnub.
K9 Qib - Kev Xaiv Tus Qauv Hauv Tebchaws, tsim nyog rau Kev Ua Haujlwm Siab Siab thiab Cov Kab Tseem Ceeb. K9 cov kav dej muaj cov phab ntsa tuab tshaj plaws thiab kev ua haujlwm siab zoo, ua rau lawv nyiam cov khoom lag luam rau cov dej hauv nroog loj, ntev - cov dej xa mus deb, siab - cov kav dej muaj zog, thiab loj - cov kav dej hauv nroog loj. Hauv cov dej num tiag tiag, ntau qhov kev hloov kho dej siv tau meej meej siv K9 qib ductile hlau kav, nrog txoj kab uas hla ntawm DN300 txog DN1000.
Qib siab dua, tus nqi siab dua
Peb qib ntawm cov kav hlau kav no txawv ntawm phab ntsa tuab, qhov hnyav, thiab lub peev xwm ntawm lub siab, thiab lawv cov nqi kuj txawv raws li- tus nqi qis mus rau siab yog K7 < K8 < K9.
Phab ntsa thickness yog qhov tseem ceeb hauv kev txiav txim siab tus nqi. Cov qib siab dua txhais tau tias cov yeeb nkab phab ntsa tuab, siv hlau ntau dua, thiab cov nqi tsim khoom ntau dua. Piv txwv li, tus nqi ntawm K9 qib DN200 yeeb nkab feem ntau yog 10% mus rau 15% siab dua li qib K7.
Thaum yuav khoom, ceev faj ntawm cov chaw tsim khoom me me muag K7 / K8 li K9. Cov nqi rau tib yam tshwj xeeb tuaj yeem sib txawv ntawm cov tuam ntxhab; Yog li ntawd, ua tib zoo xyuas cov khoom cov qhab nia, cov ntawv xeem, thiab daim ntawv pov thawj ntawm kev ua raws.
Tus yuam sij rau kev xaiv cov kav dej tsis tas yuav tsum xaiv cov qib siab tshaj plaws, tab sis yog "xaiv raws li kev xav tau"-ua raws li qhov project siab, qhov xwm txheej, thiab pob nyiaj siv los ua kom tus nqi ntau tshaj -kev ua tau zoo. Nco ntsoov, kev tiv thaiv corrosion feem ntau nyob ntawm cov txheej txheem sab hauv thiab sab nraud (xws li zinc txheej + asphalt, cement hauv ob sab phlu, thiab lwm yam), thiab tsis cuam tshuam ncaj qha rau qib K. Thaum xaiv cov kav dej, nco ntsoov xyuas kom meej cov qib, txheej txheem txheej txheem, thiab kev siv cov kev qhia tshwj xeeb, thiab qhia meej cov no hauv daim ntawv cog lus kom tsis txhob siv cov khoom tsis zoo.
