Mapaipi a HDPE akhalapo kuyambira m'ma 50s.Chochitikacho chikuwonetsa kuti mapaipi a HDPE ndi njira yothetsera mavuto ambiri a chitoliro omwe amazindikiridwa ndi makasitomala ndi akatswiri a uinjiniya ngati chitoliro choyenera pazovuta zambiri komanso kugwiritsa ntchito mosatsimikizika kuchokera kumadzi ndi gasi kupita ku mphamvu yokoka, Sewers ndi ngalande zamadzi zam'madzi zonse zatsopano. & Ntchito Zokonzanso.Chuangrongmapaipi a polyethylene amachokera ku polytholefin thermoplastic resin yomwe ilinso yakuthupi yopanda poizoni, chifukwa chake, ndiyoyenera kugwiritsidwa ntchito mosiyanasiyana.

Zoyenera:

Madzi Perekani. ChuangrongMapaipi a PE amapangidwa kuchokera ku zinthu zomwe zimakwaniritsa zofunikira za kawopsedwe za WHO ndipo izi zitha kugwiritsidwa ntchito ponyamula madzi akumwa.

-Mapaipi ndi zoyikira zokhala ndi mphamvu ya SDR 7.4 mpaka SDR 41 ya ma mainji amadzi komanso makina operekera mapaipi ndi njira zothandizira.

-Kukhetsa mapaipi ndi zoikamo kwa masika madzi m'chipinda mapaipi.

-Mapaipi okwera a zitsime.

Mosiyana ndi mapaipi amisala ndi chitsulo kapena chitsulo cha ductile, mapaipi a HDPE ndi opepuka komanso osagwirizana ndi dzimbiri.Palibe dothi lowawasa kapena madzi "ankhanza" sadzakhala ndi zotsatira pa zinthuzo.Kuphatikiza apo, zinthu zowononga, zomwe nthawi zambiri zimasokoneza magwiridwe antchito a mapaipi, zimapewedwa.Poyerekeza ndi mapaipi a PVC, mapaipi a HDPE ndi osinthika kwambiri ndipo amapereka kukana kwakukulu ngakhale kutentha kwa ziro.Mapaipi angasinthidwe mosavuta ku makonzedwe a ngalande popanda kugwiritsa ntchito zowonjezera zowonjezera. Kumbali inayi, zoopsa za fracture chifukwa cha kugwiritsira ntchito kwambiri pa malo omanga zimachepetsedwa.Makina a mapaipi a HDPE (spigot ndi socket joints) amapereka njira zingapo zolumikizirana zotalikirana.Chifukwa chake, kuyika anangula kapena ma thrust blocks sikofunikira ndipo njira yotsikirira mapaipi yokhala ndi moyo wautali ndiyotsimikizika.

Kumwa kwambiri madzi khalidwe.Kuyenerera kwa zinthu zamadzi akumwa kumatsimikiziridwa kupyolera mu mayesero odziimira okha.Kukoma kapena kununkhira kwa madzi akumwa kumakhudzidwa chifukwa chokhudzana ndi mapaipi a HDPE.Yosalala pamwamba ndi mkulu abrasion kukana zimatsimikizira madipoziti osachepera.Polyethylene imalimbana ndi dzimbiri, chifukwa chake, madzi akumwa sangaipitsidwe ndi zinthu zomwe zingawononge ngati mkuwa kapena zitsulo zolemera monga cadmium kapena lead, zomwe zimachitika pafupipafupi ndi mapaipi akale azitsulo.

ZachilengedweZinthu zaubwenzi zopangira malo aukhondo. The Zithunzi za HDPE mapaipi ndi zoyenera ndi pokhapokha zopangidwa kuchokera ku zipangizo zoteteza chilengedwe.Mwachitsanzo, mphamvu zopangira mapaipi a HDPE ndizochepa chifukwa chopanga mapaipi opangidwa ndi polyethylene.Kugwiritsa ntchito mapaipi a HDPE kumapereka njira yabwino kwambiri yothetsera chilengedwe.Dongosolo la 100% lotulutsa umboni wotayirira litha kukhazikitsidwa ndi njira zosavuta zowotcherera.Motero, kuika pangozi madzi akumwa ndi zinthu zapoizoni kumachepetsedwa.Kuphatikiza apo, kutayika kwa madzi chifukwa cha kutayikira kwa mapaipi kumapewedwa.Palibe njira ina yoperekera zinthu yomwe imapereka zabwino izi.

Za kwambiri mikhalidwe. Makina a mapaipi a HDPE amavomerezedwa kuti akhazikitsidwe mumitundu yonse yadothi.Polyethylene ndikugwiritsa ntchito kosinthika kwa njira zosiyanasiyana zolumikizirana zomwe zimatsekereza dongosolo loperekera umboni wotayirira.Chifukwa cha kulemera kopepuka komanso njira zosavuta zophatikizira, mapaipi a HOPE ndi oyenererana bwino ndi mikhalidwe yoyipa- pakuyika m'malo ovuta.

Ngalande.Chuangrongmapaipi akugwiritsidwa ntchito ngati ngalande zapansi panthaka m'nyumba, mizere ya zinyalala zamadzi owononga komanso ngati chinthu chabwino kwambiri chopangira mapaipi akuluakulu opangira zinyalala. Iwo ndi oyenerera kutaya zinyalala za mafakitale ndipo akugwiritsidwa ntchito mochulukirachulukira. zonyansa pansi pansi ndi zinyalala mapaipi.

Makampani.Zinthu monga corrosion-resistance, kuyika kosavuta, kulemera kopepuka, ndi kusinthasintha zimapangidwirachuangrongmapaipi abwino kwa mipope zovuta m'mafakitale.Ndi abwino kwa mankhwala owononga.

Gasi ndi Paipi ya Mafuta Kachitidwe. PEmapaipi olumikizira mapaipi achitsulo cha kaboni kuti azinyamulira mafuta & mipweya pamphamvu kwambiri akupezeka.Mapaipi amapangidwa mwapadera ndi malo osalala komanso osavuta kukhazikitsa.Motero mizere ya gasi ikhoza kuikidwa pamtengo wotsika.Pobowola amagwiritsidwa ntchito ngati mabowo owombera chifukwa ndi otsika mtengo. Chifukwa cha zinthu zabwino kwambiri za HDPE, zomwe zimawonetsa kulimba kwamphamvu komanso kukana dothi lolimba kwambiri. Kuphatikizana ndi kuwongolera ndi kukhazikitsa, mapaipi a HDPE ndi abwino kwambiri kunyamula zinthu ndi mitundu ina ya gasi kuphatikizapo bio-gasi.
