Ib puas xyoo dhau los, cov neeg ua haujlwm hauv Asmeskas tau muab cov yeeb nkab hlau los tsim cov dej hauv lub tebchaws.Cov khoom muaj zog, nyab xeeb, thiab txhim khu kev qha no tau sawv qhov kev sim ntawm lub sijhawm.Niaj hnubHlau Yeeb Nkabyog tsim los kom kav ntev tshaj 100 xyoo, thiab yog ib qho khoom zoo ib puag ncig vim nws cov ntsiab lus siv dua tshiab, txuag hluav taws xob thaum ua haujlwm, nws cov kav ntev, nws tus kheej rov ua dua tshiab thiab vim yog kev cog lus ntawm Kev Lag Luam Hlau Yeeb Nkab.
Cov txiaj ntsig muaj xws li:
Nws yuav tsum tau saib xyuas me ntsis thaum nws tau teeb tsa thiab tsim los kom kav ntev li 100 xyoo.
Raws li tsab ntawv ceeb toom tsis ntev los no los ntawm American Water Works Association, qhov kev pab cuam lub neej rau niaj hnub Ductile Iron Pipe yog tsawg kawg yog 105 xyoo.Muaj ntau cov yeeb nkab hlau hauv kev pabcuam hauv Teb Chaws Asmeskas dua li lwm cov khoom siv yeeb nkab, thiab Cov Hlau Yeeb Nkab muaj lub neej ntev tshaj plaws ntawm cov khoom siv hauv kev ua lag luam niaj hnub no.
Muaj ntau npaum li 98% cov ntsiab lus rov ua dua tshiab, Ductile Iron Pipe yog nws tus kheej 100% cov khoom siv rov ua dua tshiab.
2. Cov nqi qis dua los ntawm kev muaj peev xwm txaus ua rau muaj kev txuag hluav taws xob tseem ceeb thaum lub sijhawm ua haujlwm ntawm cov yeeb nkab.Ductile Iron txuag nyiaj.
Nws muaj zog txaus los tiv thaiv cov xwm txheej hnyav tshaj plaws, los ntawm kev siv lub zog siab, mus rau lub ntiaj teb hnyav thiab kev thauj mus los, mus rau cov av tsis ruaj khov.
3. Nws yog resistant rau corrosion nyob rau hauv feem ntau cov av, thiab feem ntau yuav tsum tau tsuas siv tau zoo, economical polyethylene encasement, ib tug xoob sheathing standardized los ntawm American Water Works Association, nyob rau hauv ib tug nruj ib puag ncig.
Nrog nws lub zog, ruaj khov, thiab kev tsim qauv zoo, Ductile Iron yog cov yeeb nkab ntawm kev xaiv los tiv thaiv surges thiab nce siab loadings ntau xyoo.
4. Kev teeb tsa yooj yim thiab nyab xeeb rau cov neeg ua haujlwm uas tuaj yeem txiav thiab coj mus rhaub Cov Hlau Yeeb Nkab ntawm qhov chaw.
5. Cov yeeb nkab hlau yog rugged thiab tiv thaiv kev puas tsuaj thaum tuav thiab teeb tsa.
6. Qhov zoo ntawm cov yeeb nkab Iron Pipe txhais tau hais tias cov yeeb nkab tuaj yeem yooj yim nyob hauv av nrog cov khoom siv cov yeeb nkab.
Kev phom sij ntawm kev siv PVC
Qhov hnyav, hnyav hnyav thiab muaj pov thawj kev txhawj xeeb txog kev noj qab haus huv yog txuam nrog polyvinyl chloride (PVC).Cov kev txhawj xeeb zoo heev uas cov nroog, cov nroog thiab cov tuam txhab thoob ntiaj teb tau txwv lossis txwv tsis pub siv.
1. PVC Production tsim cov tshuaj txaus ntshai xws li dioxins thiab lwm yam co toxins uas tau pom tias ua rau mob qog noj ntshav thiab yug me nyuam.Qhov tseeb, "cov kab mob qog noj ntshav" tau pom nyob ze ntawm cov chaw tsim khoom uas tsim PVC.
Thaum lub PVC yeeb nkab kev lag luam touts nws cov khoom raws li ib tug zoo dua lwm txoj rau Ductile Iron Pipe, qhov tseeb qhia lwm yam:
2. PVC yeeb nkab tsis muaj zog.Nws tsis tuaj yeem tiv taus kev ntxhov siab, tshwj xeeb tshaj yog cov kev ntxhov siab sib txawv uas ua rau cov ntsiab lus tsis muaj zog hauv cheeb tsam.
Lub neej ntev ntawm cov yeeb nkab PVC yog nyob ntawm kev ntxhov siab thiab lub sijhawm - qhov kev ntxhov siab ntau dua, qhov sai dua nws yuav poob.
3. PVC yeeb nkab yog rhiab heev rau ambient kub (nyob rau hauv tsis tshua muaj kub, PVC ua nkig thiab yuav tawg yooj yim dua, thaum nyob rau hauv warmer ib puag ncig PVC ua tsis muaj zog).
4. PVC yeeb nkab poob qhov cuam tshuam lub zog yog tias raug ultraviolet rays - PVC tuaj yeem poob txog 34% ntawm nws lub zog cuam tshuam tom qab kwv yees li ib xyoos ntawm kev raug UV hluav taws xob.
5. PVC muaj cov twj tso kua mis ntau dua thiab cov nqi hluav taws xob.Nws yog qhov kim dua los ntawm cov yeeb nkab PVC dua li Cov Hlau Yeeb Nkab vim tias Cov Hlau Hlau Yeeb Nkab muaj qhov loj hauv txoj kab uas hla.
6. PVC yeeb nkab yog qhov nyuaj rau nruab.Nws yuav tsum muaj ntau yam khoom siv rov qab, thiab nws yuav tsum tau nruab nrog tracing hlau los xyuas kom meej tias nws tuaj yeem nyob rau yav tom ntej.
7. PVC yeeb nkab yog raug rau kev puas tsuaj los ntawm lub ntiaj teb no shipping thiab tuav tej yam kev mob.Kev khawb tob dua li qhov tuab ntawm lub dime tuaj yeem cuam tshuam tag nrho qhov ntev ntawm PVC yeeb nkab.
8. Tapping PVC yeeb nkab yog qhov nyuaj thiab siv sijhawm ntev thiab tuaj yeem ua rau muaj kev phom sij - ua rau cov kav dej tawg, cov neeg ua haujlwm raug mob, thiab dej tsis zoo.
9. Nrhiav qhov xau hauv PVC yeeb nkab yog qhov nyuaj heev.Cov txheej txheem nrhiav feem ntau cuam tshuam nrog kev xa suab nthwv dej hauv cov raj xa dej, lub suab tsis zoo nyob hauv cov yeeb nkab yas.
10. PVC yeeb nkab tau raug cuam tshuam rov qab los ntawm kev cuam tshuam hauv nws cov khoom siv, uas tau ua rau ntau qhov "force majeure" ceeb toom ntawm kev poob peev txheej rau nws cov neeg siv khoom.
