Hauv av nyob rau hauv cov nroog niaj hnub no, cov kav dej xa dej ua haujlwm ntsiag to zoo li lub neej, thiab kev xaiv cov khoom siv yeeb nkab ncaj qha cuam tshuam rau kev nyab xeeb, kev ruaj ntseg, thiab cov neeg nyob hauv dej kev paub. Cov kav dej hlau, nrog rau lawv cov txiaj ntsig zoo ntawm lub zog siab, kev tiv thaiv corrosion, thiab lub neej ua haujlwm ntev, tau dhau los ua ib qho ntawm cov khoom siv dav dav thiab ntseeg siab hauv cov dej hauv nroog cov dej num hauv tsev thiab thoob ntiaj teb, ua rau lawv xaiv zoo tshaj plaws rau cov dej hauv nroog.
I. Superior Mechanical Properties, Ua kom muaj kev nyab xeeb thiab ruaj khov dej
Cov kev qhia ntawm cov kav hlau kav, xws li lub zog tensile, khoov kev ua tau zoo, hardness, elongation, cuam tshuam tsis kam, thiab siab bearing muaj peev xwm, muaj peev xwm ua tau zoo dua rau cov kav dej grey cam khwb cia hlau thiab cov kav dej ua vaj tse. Nyob rau tib lub sijhawm, lawv tshaj cov kav hlau hauv kev tiv thaiv corrosion thiab kev pabcuam lub neej.
II. Corrosion Resistance zoo heev, kom ntseeg tau ntev -Lub Sijhawm Ua Haujlwm Zoo
- Sab nrauv phab ntsa txais kev sib xyaw los tiv thaiv -corrosion system ntawm kub- txau zinc + asphalt / polyurethane txheej, haum rau cov av complex xws li salinity thiab muaj kuab paug.
- Sab hauv phab ntsa yog kab nrog Ntau dua lossis sib npaug li 5 hli tuab cement mortar kom tshem tawm cov dej acidic, inhibit scale buildup, thiab txo lub taub hau poob.
- Ua tau raws li cov qauv kev noj qab haus huv ntawm cov dej haus, nrog rau lub neej kev pab cuam ntawm ntau tshaj 50 xyoo; qee qhov haujlwm thaum ntxov tau ua haujlwm rau ntau tshaj 60 xyoo.
III. Siab -Cov Khoom Siv Dej Zoo Zoo, Kev Tiv Thaiv Cov Neeg Nyob Hauv Dej Haus Dej Kho Mob
Smooth, xeb-dawb sab hauv phab ntsa, tsis tshua muaj kab mob loj hlob thiab sediment buildup, txo cov pa phem thib ob.
Cov khoom siv ruaj khov ua kom ntev ntev -kev ua raws dej zoo, ua tau raws li cov qauv kev nyab xeeb dej haus xws li GB/T 17219.
Haum raws li cov khoom siv tseem ceeb rau cov kav dej hauv nroog thiab cov dej haus hauv tsev.
IV. Kev txhim kho yooj yim, hloov tau rau qhov chaw tsim kho kom yooj yim
Flexible Joint Design: T- hom hloov pauv tau yooj yim siv nyob rau hauv cov kav hlau kav hlau yog qhov tseem ceeb tshaj lij. Qhov kev sib koom tes no tsis tsuas yog muab kev sib khi zoo heev tab sis kuj muaj qhov zoo ductility. Thaum lub sij hawm underground nteg, qhov no yooj yooj yim adapts rau me ntsis lub hauv paus kev daws teeb meem, txhim kho qhov kev ntxhov siab ib puag ncig ntawm cov raj xa dej thiab cov av ib puag ncig. Tsis tas li ntawd, qhov thermal expansion thiab contraction ntawm cov kav dej los ntawm cov dej kub hloov tau tuaj yeem nqus tau rau qee qhov ntawm cov pob qij txha, yog li txo qhov kev pheej hmoo ntawm kev xau.
V. Strong System Compatibility thiab ua tiav kev txhawb nqa
Cov kav dej kav hlau yog sib xws nrog lub luj tshib, tees, li qub, cov kav dej tua hluav taws, thiab lwm yam fittings, tso cai rau kev sib koom ua ke ntawm cov khoom siv thiab kev sib koom ua ke thoob plaws tag nrho lub cev.
Haum rau ntau yam xwm txheej xws li hauv nroog loj kav dej, ceg tes hauj lwm, lub twj tso kua mis inlets thiab qhov hluav taws xob, thiab cov dej hauv cov chaw nyob thiab cov chaw ua si.
Ua kom yooj yim tom qab kev saib xyuas thiab kev hloov kho hauv cheeb tsam, txo qis tag nrho qhov nyuaj ntawm cov kav dej sib txuas ua haujlwm thiab kev saib xyuas.
VI. Ntev -Cov txiaj ntsig nyiaj txiag lub sij hawm
Txawm hais tias thawj zaug kev nqis peev hauv cov kav hlau kav hlau yuav yog qhov siab, lawv cov txiaj ntsig kev lag luam thoob plaws lawv lub neej tag nrho yog qhov zoo heev. Kev tiv thaiv corrosion zoo heev thiab kev kub siab ua haujlwm ua rau lub neej ua haujlwm ntev thiab ruaj khov, txo qis txij nkawm thiab nqi, nrog rau cov nqi hloov. Nyob rau hauv lub sij hawm ntev, nws yog ib tug ntau economic thiab lub luag hauj lwm xaiv.
VII. Txoj Cai Txhawb Nqa thiab Kev Tsim Kho Vaj Tse, Kev Ua Haujlwm Zoo Tshaj Plaws
Txoj cai xws li kev tsim kho nroog tshiab, kev rov ua dua tshiab hauv nroog, kev kho dua tshiab ntawm cov kav dej qub, thiab cov phiaj xwm hauv nroog sponge tseem ua rau muaj kev xav tau.
Dav dav siv nyob rau sab qab teb- mus rau-North Water Diversion Project txhawb nqa cov haujlwm, kev kho cov kav dej hauv nroog loj, thiab cov dej haus kev nyab xeeb hauv nroog.
Ua raws li cov qauv hauv tsev thiab thoob ntiaj teb xws li GB / T 13295 thiab ISO 2531, thiab yog ib qho ntawm cov khoom siv tseem ceeb rau cov kav dej hauv nroog.
Shanxi Jintai Hongye Casting & Forging Machinery Co., Ltd., nyob rau hauv Shanxi xeev, Suav teb, yog ib tug ua chaw tsim tshuaj paus ntawm ductile hlau yeeb fittings, kav, ntau yam li qub, thiab manhole npog. Peb muaj automated ntau lawm kab thiab ib tug kev paub ntau lawm technology pab neeg los muab koj nrog kev thiab hloov tau customized daws.
