Lub ntsiab lus ceev ntawm cov khoom siv yeeb nkab feem ntau: hom twg haum rau qhov xwm txheej twg?
Thaum xaiv cov yeeb nkab hom, engineers yuav tsum zam qhov "ib-size- haum-tag nrho" kev xav. Cia peb nkag siab qhov luv luv ntawm qhov chaw ntawm 6 lub ntsiab yeeb nkab hom.
cov ntaub ntawv tseem ceeb ntawm cov yeeb nkab
PPR cov kav dej
PPR cov kav dej feem ntau yog xim dawb lossis grey, lub teeb yuag, du, tsis yog - lom, thiab yooj yim rau cua sov- yaj. Lawv muab cov txiaj ntsig zoo rau cov nyiaj thiab feem ntau yog siv rau kev siv dej hauv tsev hauv tsev thiab thaj chaw nyob.
PE tub
Cov kav dej PE feem ntau yog xim dub, hloov tau yooj yim thiab khoov tau, corrosion-tiv taus thiab kev sib haum xeeb-resistant, thiab haum rau qhib cov kav dej thiab cov kav dej hauv thaj chaw sib hais.
PVC-U kav
PVC-U kav dej feem ntau yog xim dawb lossis grey, tawv tab sis nkig, pheej yig, thiab yooj yim rau nruab. Lawv tsuas yog tsim nyog rau qis - cov dej nag lossis cov kav dej phwj tuaj thiab raug txwv tsis pub siv rau cov dej.
HDPE ob - cov kav dej corrugated
HDPE ob - cov kav dej corrugated yog dub thiab corrugated, nrog lub nplhaib siab nruj thiab kev tsim kho sai. Lawv feem ntau yog siv rau cov kav dej phwj tuaj ntawm cov kav dej loj, tsis yog cov kav dej.
Cov kav dej hlau
Cov kav dej hlau yog cov xim dub / liab, nrog cov phab ntsa tuab thiab lub suab tsis zoo nkauj thaum ntaus. Lawv cov txiaj ntsig tseem ceeb yog lub zog siab thiab toughness, muaj zog siab tsis kam, zoo corrosion kuj, thiab txhim khu kev qha kev sib khi. Nrog rau kev pab cuam lub neej ntawm ntau tshaj 50 xyoo, lawv yog qhov kev xaiv zoo tshaj plaws rau cov dej hauv nroog, kev hloov dej mus ntev - deb, thiab cov dej nag hauv nroog thiab cov kav dej phwj tuaj.
Cov kav hlau
Cov kav hlau hlau feem ntau yog xim dub lossis nyiaj galvanized, muaj lub suab nrov, thiab tsis tshua muaj siab rau siab. Lawv tuaj yeem siv tau rau siab - kev xa dej siab, cov kav dej hauv kev lag luam, thiab cov chaw hla tshwj xeeb, tab sis muaj cov kev xav tau siab rau kev txhim kho thiab kev tiv thaiv corrosion.
Cov kav dej kav hlau: "tus qauv kub" rau cov dej hauv nroog
Vim li cas feem ntau txoj kev loj hauv nroog xaiv cov kav hlau kav?
nws combines lub zog thiab toughness
Spheroidized cam khwb cia hlau muaj tensile, dabtsi yog khoov, thiab kev cuam tshuam kev tiv thaiv deb tshaj li ntawm cov cam khwb cia hlau kav, thiab nws tsis yooj yim tawg txawm nyob rau hauv uneven av sib haum xeeb los yog tsheb co.
nws muaj kev ua haujlwm siab zoo heev
nrog nominal pressures xws li PN10 mus rau PN40, tag nrho npog cov pa dej qhov xwm txheej ntawm 0.6 mus rau 1.0 MPa, thiab cov qib siab siab kuj tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm tshwj xeeb.
Hais txog kev tiv thaiv corrosion
ductile hlau kav muaj ib tug paub tab los tiv thaiv-corrosion system: ib tug sab nraud zinc txheej ntxiv rau asphalt / epoxy resin xim tiav txheej, thiab cov cement mortar hauv ob sab phlu, uas tuaj yeem tiv taus cov av sab nraud corrosion thiab xyuas kom meej tias cov dej tsis zoo.
nws lub interface yog kev ruaj ntseg kaw
txais T- hom qhov (socket) hloov pauv hloov pauv, muaj qhov nrawm nrawm nrawm, thiab tuaj yeem hloov kho rau qee lub kaum sab xis ntawm deflection, tiv thaiv kom tsis txhob xau.
Cov khoom siv yeeb nkab sib piv
Piv nrog rau lwm cov khoom siv yeeb nkab, cov kav hlau yeeb nkab muaj qhov zoo dua
Piv nrog rau cov kav hlau, txawm hais tias cov kav hlau steel tseem muaj zog tiv thaiv sab nraud, lawv lub sijhawm ntev - corrosion kuj tsis zoo, yuav tsum muaj kev tiv thaiv tsis tu ncua -corrosion txij nkawm thiab ua rau tag nrho lub neej ntau dua - mus txog tus nqi. Hauv qhov sib piv, cov kav hlau hlau tuaj yeem kav ntev dua 50 xyoo nyob rau hauv ib txwm ua haujlwm, thiab thaum cov txheej txheem tiv thaiv -corrosion tsis zoo, lawv yuav luag tsis muaj kev kho loj. Qhov nruab nrab tus nqi tu txhua xyoo tsuas yog kwv yees li ib -tsib tsib ntawm cov kav hlau.
Piv nrog rau PE kav, PE kav dej muaj kev tiv thaiv corrosion zoo dua tab sis tsis muaj zog tiv thaiv sab nraud. Hauv qhov loj - txoj kab uas hla, siab - lub zog dej hauv nroog cov xwm txheej, cov kav dej hlau muaj qhov zoo dua hauv kev nruj thiab ruaj khov.
Hauv cov ntsiab lus, rau cov kav dej hauv nroog loj nrog txoj kab uas hla ntawm DN100 txog DN1200, siab ntawm 0.6 txog 1.6 MPa, thiab lub neej tsim tsis pub tsawg tshaj 50 xyoo, cov kav dej hlau yog cov nqi ntau tshaj - kev xaiv zoo.
Muab cov lus qhia txog kev yuav khoom rau qhov project
Rau qhov kev yuav khoom thiab cov neeg ua haujlwm engineering, muaj ntau cov lus qhia tsim nyog sau cia.
01. Tsis txhob saib tus nqi pib thawj zaug
Tus nqi pib ntawm cov yeeb nkab hlau yuav yog me ntsis siab dua li ntawm PE yeeb nkab rau txoj kab uas hla me me (tab sis nws muaj nqi zoo dua rau txoj kab uas hla loj). Txawm li cas los xij, nws yuav luag tsis muaj kev kho loj thaum nws muaj tsib caug- xyoo lifespan. PE yeeb nkab muaj kev pheej hmoo siab dua ntawm kev laus nyob rau hauv lub siab hloov pauv thiab raug UV. Nyob rau hauv cov nqe lus ntawm tag nrho cov nqi kev ua tau zoo, ductile hlau yeeb nkab yog ua tau zoo dua.
02. Lub interface yog qhov tseem ceeb
Lub qhov (socket) - hom hloov pauv hloov pauv yog qhov tseem ceeb ntawm cov kav hlau kav hlau, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam hauv av mos, uas tuaj yeem tiv thaiv cov yeeb nkab tawg.
03. Xaiv cov tuam txhab muaj npe nrov
Kev ua lag luam muaj teeb meem xws li tsis yog - tus qauv phab ntsa thickness txo, cov roj hmab tsis zoo, thiab kev siv cov khoom tsis zoo. Tsuas yog los ntawm kev xaiv cov tuam txhab lag luam uas ua tau raws li lub teb chaws cov qauv thiab muaj kev lees paub zoo ua tiav koj tuaj yeem ua kom muaj kev nyab xeeb ntev ntev ntawm koj qhov project.
