Muaj ib zaug HDPE kav thiab fittings tsuas yog saib raws li lwm yam khoom nyob rau hauv ib pawg ntawm ntau yam kev xaiv rau infrastructure tej yaam num nyob rau hauv teb chaws Africa.
Tam sim no lawv tau dhau los ua qhov tsim nyog, lawv qhov tseem ceeb tau txhim kho los ntawm cov kev xav tau niaj hnub ntawm peb lub sijhawm.
Cov neeg uas tau ua tib zoo saib tuaj yeem nco ntsoov hloov pauv tus cwj pwm hauv kev xaiv cov khoom siv thoob ntiaj teb, nrog rau kev nyiam ntau ntxiv rau cov khoom lag luam uas hais txog peb tiam neeg tseem ceeb - tus nqi thiab kev nco qab ib puag ncig.
Qhov no yog qhov tseem ceeb hauv kev lag luam piping, hauv kev siv cov high-density polyethylene (HDPE) kav thiab fittings tshwj xeeb.
Nws yog ib qho nyuaj rau tsis quav ntsej qhov kev tsis ncaj ncees ntawm HDPE kav thiab fittings vim lawv cov yam ntxwv ntsuab thiab kev sib piv cov nqi-zoo.
Ib txoj kev tshawb fawb tsis ntev los no los ntawm South African Plastic Pipes Manufacturers Association (SAPPMA) Technical Committee qhia txog kev noj qab haus huv rau HDPE kav thiab fittings raws li cov khoom tsim nyog los daws cov teeb meem kev txhim kho tam sim no.
Feem ntau, txoj kev tshawb nrhiav pom tau hais txog cov txiaj ntsig tseem ceeb uas HDPE coj los ua tus nqi qis zog, tsis muaj kev cuam tshuam ib puag ncig, thiab kev ua haujlwm qis thiab kev saib xyuas cov nqi tshaj cov khoom tsim los ntawm lwm cov ntaub ntawv.
Raws li Ben Levitas ntawm African Pipes Valves thiab Fittings (APVF), kev ua lag luam rau HDPE kav thiab fittings tau loj hlob sai dua li lwm cov txheej txheem thermoplastic.
"Peb tab tom ua raws li tus qauv uas tau pib hauv Tebchaws Europe.
Cov yeeb nkab muaj ntau yam khoom, tiv thaiv corrosion, cuam tshuam lub zog, UV tsis kam, yooj yim ntawm installation, thiab txawm tias tshuaj tiv thaiv.
Hauv South Africa, muaj txog 14 lub tuam txhab ua tau raws li cov qauv thoob ntiaj teb, yog li cov yeeb nkab tau yooj yim thiab cov nqi sib tw. Ntau ntawm cov tuam txhab tsim khoom no nyob ntawm kev xa tawm, thiab muab cov mines kom deb li deb ntawm DRC. "
