Ukuhlanganisa amapayipi kubalulekile, kodwa ukuxhumeka okubuthakathaka kuholela ekuhlulekeni. Ukuhlanganiswa kwe-HDPE kudala isibopho esihlala njalo, esiqinile, okuqinisekisa ubuqotho besistimu kanye nokuthula kwengqondo amashumi eminyaka.

I-HDPE coupling isetshenziselwa ukuhlanganisa ubude obubili bepayipi le-HDPE. Ngokuhlanganisa ukushisa, idala uxhumano oluqhubekayo, olungavuzi oluqinile njengepayipi uqobo. Lokhu kususa amaphuzu abuthakathaka omshini futhi kuqinisekisa ukuthembeka kwesikhathi eside ezisetshenzisweni ezifihliwe noma ezibalulekile.

Ngibone amaphrojekthi amaningi ephumelela noma ehluleka ngokusekelwe entweni eyodwa: ikhwalithi yejoyinti. Eminyakeni yami engu-18 njengomkhiqizi, ngifunde ukuthi ipayipi liyipayipi nje, kodwa iphuzu lokuxhuma yilapho ubunjiniyela nekhwalithi kubaluleke khona ngempela.Ukuhlanganiswa kwe-HDPEakuyona nje isixhumanisi; iyisiqinisekiso sesistimu engenazihibe. Lokhu kuyiqiniso ikakhulukazi ezindaweni ezidinga kakhulu njengalezo zase-Indonesia, lapho ukuphathwa kwamanzi okuthembekile kubalulekile khona. Ake sibheke ukuthi lokhu kuxhumana kwenziwa kanjani nokuthi kungani kuphakeme kangaka kunezindlela zendabuko.

Uxhumanisa kanjani i-HDPE ne-HDPE?

Ukuxhuma amapayipi e-HDPE kungabonakala kuyinkimbinkimbi. Ukusebenzisa indlela engalungile kungadala indawo ebuthakathaka ezohluleka ngaphansi kwengcindezi. Ukuhlanganiswa kokushisa kuyindlela kuphela yokuwaxhumanisa ngempela.

Uxhuma i-HDPE ku-HDPE usebenzisa izindlela zokuhlanganisa ukushisa. Ezivame kakhulu ukuhlanganisa izinqe zamapayipi amakhulu, ukuhlanganisa amasokhethi amapayipi amancane, kanye nokuhlanganisa ngogesi ukuze kulungiswe. Lezi zindlela zincibilikisa izindawo zepulasitiki ndawonye, ​​zidale ijoyinti elilodwa, eliqinile, nelingavuzi nhlobo uma lipholile.

Umqondo oyinhloko ngemuva kokuxhuma i-HDPE akukhona ukuyihlanganisa nje, kodwa ukuyihlanganisa. Sibumba kabusha izingcezu ezimbili ezihlukene zibe yinye. Ngokungafani ne-PVC esebenzisa iglue noma amapayipi ensimbi asebenzisa imicu, i-HDPE isebenzisa uhlobo lwayo lwe-thermoplastic ngendlela ezuzisayo. Ngokusebenzisa ukushisa okulawulwayo, siletha izinto endaweni yazo yokuncibilika. Uma sezincibilikile, amaketanga e-polymer avela kokubili epayipini kanye nokufakwa akhululekile ukuhlangana ndawonye. Njengoba sisebenzisa ingcindezi futhi sivumela ukuthi iphole, la maketanga ayahlangana futhi aqine, adale isibopho esiqinile, uma singenamandla, kunodonga lokuqala lwepayipi. Lokhu yilokho esikubiza ngokuthi uhlelo lwe-monolithic—kunjengokungathi lonke ipayipi lenziwe ngepulasitiki eyodwa kusukela ekuqaleni. Lokhu kususa noma iyiphi indlela engaba khona yokuvuza, ukukhathazeka engivame ukukuzwa konjiniyela abaphatha ingqalasizinda yamanzi ebalulekile.

Ukudala Uhlelo Lwe-Monolithic

Iyini ifomu eliphelele le-HDPE?

Sisebenzisa amagama afingqiwe embonini nsuku zonke ngaphandle kokucabanga kabili. Kodwa ukungazi ukuthi kusho ukuthini i-HDPE kungafihla izimfanelo zayo ezinhle kakhulu. Ukuqonda igama layo kwembula ukuthi kungani iyinto engcono kakhulu.

I-HDPE imele i-High-Density Polyethylene. Iyi-polymer ye-thermoplastic eyaziwa ngesilinganiso sayo esimangalisayo samandla-kuya-sobuningi. Lesi sakhiwo "se-High-Density" yisona esinikeza ipayipi ukuqina kwayo, ukumelana namakhemikhali, kanye nokuqina, okwenza ifaneleke kakhulu kumaphrojekthi engqalasizinda adinga amandla.

Ake sichaze igama, ngoba likutshela konke okudingeka ukwazi. Igama elithi “Polyethylene” libhekisela esakhiweni se-polymer esiyisisekelo—amaketanga amade ama-molecule e-ethylene. Liyipulasitiki elula kakhulu futhi ezinzile. Ingxenye ebalulekile “yi-High-Density”. Ngesikhathi senqubo yokukhiqiza, sakha la maketanga e-polymer ngeamagatsha amancane kakhuluLokhu kuzivumela ukuthi zihlangane ndawonye, ​​​​zidale isakhiwo esiqinile, esicwebezelayo. Lokhu kuxinana okuphezulu kubhekene ngqo nezici ezinhle kakhulu zezinto: ukuqina kwazo, amandla, kanyeukumelana okuhle kakhulu namakhemikhali kanye nokugugulekaNjengomkhiqizi, sisebenza kakhulu ne-PE100, izinga eliphezulu le-HDPE. Uma uyiqhathanisa nezinye izinto, izinzuzo zayo ziba sobala kakhulu.

Lokho Igama Elikutshela Khona

Ingabe i-HDPE inamalunga?

Emapayipini endabuko, amalunga ayimbangela yokuqala yokuvuza nokwehluleka. Lokhu kuyimbangela eqhubekayo yokukhathazeka. Ngokuhlangana kwe-HDPE, la maphuzu abuthakathaka endabuko ayanyamalala nje.

Cha, uhlelo lwe-HDPE oluhlanganiswe kahle alunawo amalunga ngomqondo wendabuko. Inqubo yokuhlanganisa ukushisa idala ipayipi elilodwa. Indawo yokuxhuma iba yipulasitiki eqhubekayo enamandla nobuqotho obufanayo nodonga lwepayipi uqobo.

Lo mbuzo ufika enhliziyweni yokuthi kungani i-HDPE ishintshashintsha kangaka. Uma abantu becabanga “ngejoyinti,” bacabanga ngokuxhumana kwemishini—i-gasket, i-flange enama-bolts, noma i-threading fitting. Lezi yizindawo lapho izingxenye ezimbili ezahlukene ziphoqelelwa khona ndawonye, ​​okudala indlela engaba khona yokuvuza.Ukushintshwa kwe-HDPE fusionkuhluke ngokuphelele. Akuyona ijoyinti; kuyaqhubeka. Awekho ama-gasket okufanele ancishiswe, awekho amabhawodi okufanele aqiniswe kabusha.

Emaphrojekthini amaningi engqalasizinda lapho izimo zomhlaba zingase zingazinzile, lokhu kuyinzuzo enkulu. Ipayipi eliqinile elinamajoyinti emishini lizovuza lapho umhlaba ushintsha.ipayipi le-HDPE eliguquguqukayo, elinobunyeihamba nomhlabathi, igcina ubuqotho bayo. Isusa isici esisodwa esikhulu sengozi kunoma yimuphi umsebenzi wepayipi eligqitshiwe.

Inzuzo Yesistimu 'Engenamajoyinti'

Yiziphi izindlela zokuxhuma ipayipi le-HDPE?

Uyazi ukuthi i-HDPE idinga ukuhlanganiswa, kodwa kunezindlela eziningana zokwenza lokho. Ukukhetha indlela engalungile yomsebenzi kungachitha isikhathi nemali, kubeke engcupheni ubuqotho bephrojekthi yakho.

Izindlela ezintathu eziyinhloko zokujoyina ipayipi le-HDPE zonke zisekelwe ekuhlanganisweni kokushisa. Ukuhlanganiswa kwe-Butt kungokwemipayipi emikhulu (63mm+), ukuhlanganiswa kwe-socket kungokwemipayipi emincane (kufika ku-110mm), kanti ukuhlanganiswa kwe-electromagnetic kulungele ukulungiswa, ukubopha, kanye nezimo lapho ezinye izindlela zingasebenzi khona.

Nakuba zonke izindlela zisebenzisa ukushisa, zenzelwe izimo ezahlukene.Ukuhlanganiswa kwezinqeiyinsika enzima kakhulu yengqalasizinda enkulu. Kuhilela ukubheka ngqo iziphetho zamapayipi, ukuwafudumeza epuletini, nokuwacindezela ndawonye ukuze kwakheke i-weld.

Ngobubanzi obuncane,Ukuhlanganiswa kwesokhethikuyashesha futhi kulula kakhulu. Lapha, sifudumeza ingaphandle lepayipi kanye nengaphakathi lesokhethi lokufaka ngesikhathi esisodwa ngaphambi kokuzicindezela ndawonye.

Ekugcineni, kukhonaUkuhlanganiswa kwe-ElectroLezi zihlanganisi zinezikhoyili zokushisa ezakhelwe ngaphakathi. Uslayida isihlanganisi phezu kwamapayipi, usixhuma emthonjeni wamandla, bese izikhoyili zincibilikisa ipulasitiki kusukela ngaphakathi kuya ngaphandle.

Kukhona futhi nokufakwa kwemishini, kodwa lokhu ikakhulukazi kungokokushintshela kwezinye izinto zamapayipi noma ukusetha kwesikhashana, hhayi kokudala ipayipi eliyinhloko nelihlala njalo.

Ukufanisa Indlela Nesicelo

Isiphetho

An Ukuhlanganiswa kwe-HDPEihlanganisa ipayipi ibe uhlelo oluqhubekayo, olungavuzi. Ukuqonda indlela efanele yokuhlanganisa kuyisihluthulelo sokwakha ingqalasizinda eqinile, ethembekile, futhi engenazo izinkinga zendabuko zokuhlangana.
