Mapaipi a HDPE akhalapo kuyambira pakati pa zaka za m'ma 50. Zomwe zachitikazi zikusonyeza kuti mapaipi a HDPE ndi njira yothetsera mavuto ambiri a mapaipi omwe amavomerezedwa ndi makasitomala ndi alangizi a mainjiniya ngati zipangizo zoyenera kwambiri zogwiritsira ntchito mphamvu zambiri komanso zosakakamiza kuyambira kugawa madzi ndi gasi mpaka mphamvu yokoka, zimbudzi ndi ngalande zamadzi pamwamba pa ntchito zatsopano ndi zokonzanso.ChuangrongMapaipi a polyethylene amachokera ku polytholefin thermoplastic resin yomwe ndi chinthu chopanda poizoni m'thupi, motero, ndi yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.

Yoyenera:

Madzi Kupereka. ChuangrongMapaipi a PEAmapangidwa kuchokera ku zinthu zomwe zikukwaniritsa zofunikira za poizoni za WHO ndipo izi zitha kugwiritsidwa ntchito ponyamula madzi akumwa.

-Mapaipi ndi zolumikizira zokhala ndi mphamvu ya SDR 7.4 mpaka SDR 41 pa mapaipi akuluakulu amadzi komanso makina ogawa mapaipi ndi mizere yogwirira ntchito.

-Mapaipi otulutsa madzi ndi zolumikizira za mapaipi a chipinda cha madzi a kasupe.

-Mapaipi okwera a zitsime.

Mosiyana ndi mapaipi opangidwa ndi chitsulo kapena chitsulo chosungunuka, mapaipi a HDPE ndi opepuka komanso osapsa. Dothi lonyowa kapena madzi "oopsa" sadzakhudza zinthuzo. Kuphatikiza apo, zinthu zowononga dzimbiri, zomwe nthawi zambiri zimasokoneza magwiridwe antchito a mapaipi, sizimapewedwa. Poyerekeza ndi mapaipi a PVC, mapaipi a HDPE ndi osinthika kwambiri ndipo amapereka kukana kwakukulu ngakhale kutentha kutakhala kopanda zero. Mapaipi amatha kusinthidwa mosavuta kuti agwirizane ndi kapangidwe ka ngalande popanda kugwiritsa ntchito zowonjezera. Kumbali inayi, zoopsa zosweka chifukwa cha zovuta kwambiri pa malo omanga zimachepetsedwa. Makina a mapaipi a HDPE (spigot ndi socket joints) amapereka njira zosiyanasiyana zolumikizirana kwa nthawi yayitali. Chifukwa chake, kuyika kwa anchors kapena ma thrust blocks sikofunikira ndipo makina a mapaipi osatulutsa madzi okhala ndi moyo wautali ndi otsimikizika.

Kumwa kwambiri madzi khalidwe.Kuyenerera kwa zinthuzo pa madzi akumwa kumatsimikiziridwa kudzera mu mayeso odziyimira pawokha. Kukoma kapena fungo la madzi akumwa sikukhudzidwa chifukwa cha kukhudzana ndi mapaipi a HDPE. Malo osalala komanso kukana kwamphamvu kwa kukwawa kumatsimikizira kuti madziwo sadzalowa m'madzi. Polyethylene imalimbana ndi dzimbiri, motero, madzi akumwa sangaipitsidwe ndi zinthu zina monga mkuwa kapena zitsulo zolemera monga cadmium kapena lead, zomwe zimachitika kawirikawiri ndi mapaipi akale achitsulo.

ZachilengedweZinthu zothandiza kuti malo akhale oyera. The HDPE mapaipi ndi kuyika ndi kokha zopangidwa kuchokera ku zipangizo zosawononga chilengedwe. Mwachitsanzo, mphamvu zomwe zimafunika popanga mapaipi a HDPE ndizochepa chifukwa cha kupanga mapaipi opangidwa ndi polyethylene. Kugwiritsa ntchito mapaipi a HDPE kumapereka yankho labwino kwambiri pa chilengedwe. Dongosolo lothandizira madzi losatayikira 100% likhoza kukhazikitsidwa ndi njira zosavuta zolumikizira. Chifukwa chake, kuyika madzi akumwa pachiwopsezo ndi zinthu zoopsa kumachepa. Kuphatikiza apo, kutaya madzi chifukwa cha mapaipi otayikira kumapewedwa. Palibe dongosolo lina lothandizira lomwe limapereka zabwino izi.

Kwa kwambiri mikhalidwe. Mapaipi a HDPE amavomerezedwa kuti aikidwe m'nthaka yamitundu yonse. Polyethylene ndi njira yosinthika yolumikizirana pogwiritsa ntchito njira zosiyanasiyana zolumikizirana zomwe zimateteza njira yotulutsira madzi. Chifukwa cha kulemera kwake kochepa komanso njira zosavuta zolumikizirana, mapaipi a HOPE ndi oyenera kwambiri pamikhalidwe yoipa - yoyikira m'malo ovuta.

Madzi otayira madzi.ChuangrongMapaipi akugwiritsidwa ntchito ngati njira yotulutsira madzi pansi pa nthaka ya nyumba, zinyalala zotayira madzi owononga komanso ngati chinthu choyenera kwa opanga mapaipi akuluakulu otayira zinyalala. Ndi abwino kwambiri potaya zinyalala zamafakitale ndipo akugwiritsidwa ntchito kwambiri ngati mapaipi otayira zinyalala pansi pa nthaka ndi zinyalala.

Makampani.Zinthu monga kukana dzimbiri, kuyika kosavuta, kulemera kopepuka, komanso kusinthasintha zimapangitsachuangrongMapaipi ndi abwino kwambiri popangira mapaipi ovuta m'mafakitale. Ndi abwino kwambiri popangira mankhwala owononga.

Gasi ndi Chitoliro cha Mafuta Machitidwe. PEMapaipi olumikizira mapaipi achitsulo cha kaboni kuti anyamule mafuta ndi mpweya pamphamvu kwambiri alipo. Mapaipiwa adapangidwa mwapadera ndi malo osalala ndipo amapangidwa kukhala osavuta kuyika. Chifukwa chake mizere ya gasi imatha kuyikidwa pamtengo wotsika. Pobowola amagwiritsidwa ntchito ngati zitseko za mabowo chifukwa ndi otsika mtengo. Chifukwa cha mawonekedwe abwino a HDPE, omwe ali ndi mphamvu yayikulu komanso kukana bwino nthaka yolimba. Pophatikizidwa mosavuta pakuyigwiritsa ntchito ndikuyiyika, mapaipi a HDPE ndi abwino kwambiri ponyamula zinthu ndi mitundu ina ya gasi kuphatikiza bio-gas.
