Ukhathazekile ngokukhetha isixhumi esingalungile semigqa yakho yamanzi? Ukufakwa okungalingani epayipini le-PE kungaholela ekuvuzeni, ekulahlekelweni yingcindezi, kanye nokulungiswa okubizayo nokuphazamisayo.

Ukufakwa kwe-PEziyizixhumi ezenzelwe ngqo amapayipi e-Polyethylene (PE). Zakha amajoyinti aqinile ale nto eguquguqukayo futhi eqinile kusetshenziswa izindlela ezifana nokucindezela ngomshini noma ukuhlanganiswa kokushisa, okuqinisekisa ukuthi uhlelo lwamapayipi noma lokunisela aluvuzi futhi luhlala isikhathi eside.

Ukuthembeka kwanoma yiluphi uhlelo lwamapayipi kuncike ekuxhumeni kwalo. Njengomuntu owakhe inkampani esezingeni lomhlaba.izixazululo zokuphathwa kwamanzi, Ngiyazi ukuthi ipayipi liqinile kuphela njengokuhlangana kwalo okubuthakathaka kakhulu. Kumphathi wokuthenga onjengoCarlos, ukugcina izinto ezifanele akukhona nje ukugcwalisa i-oda; kumayelana nokuhlinzeka ngezingxenye eziqinisekisa ubuqotho besistimu amashumi eminyaka.

I-PE imelelani ekufakweni kwamapayipi?

Uyalibona igama elithi “PE” kuma-spec sheet bese uzizwa ungaqiniseki? Uku-oda ngokusekelwe ekuqageleni kungaholela ezintweni ezingahambisani, ukubambezeleka kwephrojekthi, kanye nokulahlwa kwempahla.

I-PE imele nje i-Polyethylene. Iyi-thermoplastic eqinile, eguquguqukayo, futhi engagqwali esetshenziselwa ukwenza amapayipi amanzi amakhulu, ukunisela, kanye nokusatshalaliswa kwegesi. Ukufakwa kwe-PE kuyizixhumanisi ezenzelwe ukujoyina la mapayipi athile.

Ngihlala ngitshela ithimba lami ukuthi ukucaca kuwumusa. Ukusebenzisa amagama alula kusiza wonke umuntu ukuba enze izinqumo ezingcono. Uma uCarlos eqonda ukuthi i-PE imane isho i-Polyethylene, angakhuluma ngokuzethemba okukhulu namakhasimende akhe, kusukela kosonkontileka abakhulu kuya kubalimi bendawo. Akayena nje umthengisi; ungumqondisi ochwepheshe, oqinisekisa ukuthi amakhasimende akhe athola ikhambi eliqinile neliguquguqukayo elinikezwa yi-Polyethylene ngezidingo zawo ezithile, ikakhulukazi ezindaweni ezingaphansi komhlaba noma ezidinga kakhulu.

Ukuqonda Indima Ye-Polyethylene

I-Polyethyleneuhlobo lwepulasitiki olubizwa ngokuthii-thermoplastic, okusho ukuthi ingancibilikiswa futhi ilungiswe. Lesi sici siyisihluthulelo kwezinye zezindlela zayo zokuxhuma. Ukuthandwa kwayo ekufakeni amapayipi kuvela ezinzuzweni zayo ezinkulu kunezinto zendabuko njengensimbi. Ayigqwali noma ibole ngenxa yamakhemikhali asenhlabathini noma emanzini, futhi ukuguquguquka kwayo kuvumela ukuthi ifakwe ngamajoyinti ambalwa, okunciphisa izindawo ezingase zivuvuke.

Ubuningi Obuhlukene Bemisebenzi Ehlukene

Akuzona zonke izinhlobo ze-PE ezifanayo. Umehluko omkhulu ozowubona ubuningi bayo. Lokhu kubalulekile ekukhetheni ipayipi elifanele lomsebenzi.

Isici	I-HDPE (i-Polyethylene Enobuningi Obuphezulu)	I-LDPE (i-Polyethylene Ephansi)
Isakhiwo	Ukuqina kakhulu futhi kuqinile	Kuthambile futhi kuyaguquguquka kakhudlwana
Isilinganiso Sokucindezela	Okuphakeme	Ngaphansi
Ukusetshenziswa Okuvamile	Imigqa emikhulu yokuphakelwa kwamanzi, imigqa yegesi, imigudu yamandla kagesi	Ukunisela ngokucindezela okuphansi, amapayipi okuconsa, imigqa yobubanzi obuncane
Ukubukeka	Ngokuvamile kumnyama oqinile, ngezinye izikhathi kunomugqa onemibala	Ngokuvamile kumnyama oqinile, kuzwakala kuthambile uma kuthintwa

KuCarlos, ukugcwalisa kokubili izinto zokufaka ezilinganiswe nge-HDPE kanye nezinto zokufaka ezihambisana ne-LDPE kumvumela ukuthi akhonze amakhasimende amaningi, kusukela kumaphrojekthi amanzi kamasipala kuya ezinhlelweni zokunisela zezolimo.

Yiziphi izinto zokufakelwa ozisebenzisayo kumapayipi e-polyethylene?

Unepayipi elifanele, kodwa ulixhuma kanjani ngaphandle kokudala indawo ebuthakathaka? Ukusebenzisa uhlobo olungalungile lokuhlanganisa kuyindlela eqinisekisiwe yokuvuza kanye nokwehluleka kwesistimu.

Izinhlobo ezintathu eziyinhloko zokufakelwa kwamapayipi e-PE ziyimishiniukufakwa kokucindezelwa, ukufakwa kwe-butt fusion, futhiukufakwa kwe-electrofusionUkukhetha okungcono kuncike kububanzi bepayipi, izidingo zokucindezela, nokuthi ingabe ijoyinti idinga ukuhlala unomphela.

Ngibone amaphrojekthi ezigidigidi zamaRandi encike ekuqineni kwalezi zihlanganisi. Ukukhetha kubalulekile. Ukufakwa okulula kokucindezela kuhle kakhulu emugqeni wokunisela engadini. Kodwa emzileni wamanzi wedolobha onengcindezi ephezulu ogqitshwe ngaphansi komgwaqo, udinga ukuqiniseka okuphelele kwe-ukushintshwa kwe-fusionUkuqondisa ikhasimende ekukhetheni okulungile, njengoba kwenza uCarlos, kuvimbela izinhlekelele zesikhathi esizayo futhi kwakha ukwethembana okukhulu.

Ukufakwa Kokucindezela Kwemishini

Lezi yizinketho ezilula kakhulu ukuzisebenzisa. Zisebenza njengesikulufu. Uslayida inathi kanye nendandatho yokubamba phezu kwepayipi, ufake isiqinisi ngaphakathi kwephayiphi, uyicindezele emzimbeni ofanele, bese uqinisa inathi. Lokhu kucindezela indandatho, kwenze uphawu olungangeni manzi. Zilungele ububanzi obuncane (ngokuvamile kufika kuma-intshi angu-4 noma angu-110mm), ukulungiswa, kanye nokusetshenziswa okungaphezu komhlabathi. Inzuzo yazo eyinhloko ukuthi azidingi amathuluzi akhethekile futhi kulula ukuzifaka noma ukuzisusa.

Izinto Zokuhlanganisa Ukushisa

Kumapayipi amakhulu kanye nokusetshenziswa komfutho ophezulu, ukuhlanganiswa kokushisa kuyindinganiso. Le nqubo empeleni iyancibilikisa ipayipi futhi ihlanganiswe ndawonye ibe yingcezu eyodwa yepulasitiki eqhubekayo, idale ijoyinti eliqinile njengepayipi uqobo.

Isici	Ukuhlanganiswa Kwezinqe	Ukuhlanganiswa kwe-Electro
Inqubo	Amapayipi kanye neziphetho zokufaka ziyashiswa epuletini bese zicindezelwa ndawonye.	Kusetshenziswa i-fitting ene-heating coil eyakhelwe ngaphakathi. Umshini uthumela ugesi kuma-coil, uncibilikise ipulasitiki kusukela ngaphakathi kuya ngaphandle.
Amathuluzi	Umshini omkhulu, wokuhlanganisa izinqe ze-hydraulic.	Iprosesa encane, ephathekayo ye-electrofusion.
Ukusetshenziswa Okuhle Kakhulu	Amapayipi amakhulu aqondile ageleza emiseleni evulekile, aqondile.	Ukulungiswa, izindawo eziqinile, ukuxhuma emigqeni ekhona, noma yisiphi isimo lapho ukuhambisa ipayipi kunzima khona.

Kwimpahla kaCarlos, ukufakwa kokucindezela kuyinto ebalulekile ekuthengisweni kwansuku zonke. Ukufaka izinto zokuhlanganisa kanye nokufinyelela imishini kumbeka njengomhlinzeki wamaphrojekthi amakhulu engqalasizinda.

Ingabe i-PE iyafana ne-PEX?

Ingabe uphatha i-PE ne-PEX njengokungathi ziyinto efanayo? Lokhu kudideka okuvamile kungaholela ekwehlulekeni okukhulu kokufakwa, ikakhulukazi uma kuhileleke amanzi ashisayo.

Cha, azifani. I-PE yi-Polyethylene. I-PEX yi-Cross-Linked Polyethylene. Inqubo "yokuxhumanisa" inikeza i-PEX ukumelana nokushisa okuphezulu kakhulu, okwenza kube yindinganiso yemigqa yamanzi ashisayo nabandayo ngaphakathi kwezakhiwo.

Ngake ngabonisana ngecala lapho umakhi asebenzisa khonaIpayipi le-PEngokuxhumeka kwe-heater yamanzi ashisayo ngoba yayishibhile. Ipayipi lathamba futhi laqhuma phakathi nesonto, okwabangela umonakalo omkhulu wamanzi. Lesi yisibonelo esiphelele sokuthi kungani lo mehluko ubalulekile. Kumphathi wokuthenga onjengoCarlos, ukuchaza lo mehluko akukhona nje ukuthengisa ngokweqile; kuvimbela iphutha eliyingozi nelibizayo kumakhasimende akhe.

U-“X” Umehluko Oyinhloko

IgamaukuxhumanisaKuzwakala kuyinkimbinkimbi, kodwa kungumqondo olula. Cabanga ngezitebhisi ezimbili ezihambisanayo (amaketanga e-PE polymer). Manje, cabanga ngokufaka imigqa phakathi kwalawo maleveli amabili. Lokho ukuxhumanisa. Lokhu kudala isakhiwo sama-molecule esiqinile nesizinzile esingaphatha ukushisa kanye nengcindezi ephezulu ngaphandle kokuguquka. I-PE ayinazo lezi "migqa," ngakho-ke izothamba emazingeni okushisa lapho i-PEX ihlala iqinile khona.

I-PE vs. i-PEX: Ukuqhathanisa Okucacile

Isici	I-PE (i-Polyethylene)	I-PEX (i-Cross-Linked Polyethylene)
Ukusetshenziswa Kwamanzi Ashisayo	Cha, akufaneleki emanzini ashisayo.	Yebo, kuhle kakhulu emanzini ashisayo nabandayo.
Isicelo Esiyinhloko	Imisele yamanzi engaphansi komhlaba, ukuchelela, imigqa yegesi.	Amapayipi angaphakathi ezindlu nezakhiwo zebhizinisi.
Izinto zokufaka	Ukucindezela, Ukuhlanganiswa Kwezinqe, Ukuhlanganiswa Kwe-Electro.	I-Crimp, i-Clamp, i-Expansion, i-Push-to-Connect.
Ukuzivumelanisa nezimo	Iguquguquka ngama-arcs amakhulu.	Iguquguquka kakhulu, ingenza ukugoba okuqinile.
Ukumelana ne-UV	Ngokuvamile kuhle (umnyama ungcono kakhulu).	Kubi, akumelwe kuvezwe elangeni.

Ukwazi leli thebula ngekhanda kubalulekile kunoma ubani osebhizinisini lokuhlinzeka ngamapayipi. Kuqinisekisa ukuthi uhlinzeka ngezinto ezifanele zomsebenzi ofanele, njalo.

Isiphetho

Ukufakwa kwe-PExhuma ipayipi le-Polyethylene usebenzisa izindlela zokucindezela noma zokuhlanganisa. Zihlukile kuma-fitting e-PEX, angowamanzi ashisayo. Ukukhetha uhlobo olufanele kuqinisekisa uhlelo oluqinile, olungavuzi.
