Impumelelo yephrojekthi yakho incike ekuxhumeni okuqinile kwamapayipi. Ijoyinti elibuthakathaka lingabangela ukuvuza okukhulu, okuholela ekulungisweni okubizayo kanye nokubambezeleka. Ukuthola uxhumano kusukela ekuqaleni kubalulekile.

Izindlela ezinhle kakhulu zokujoyina amapayipi amabili e-HDPE yilezi:ukuhlanganiswa kwezinqefuthiukuhlanganiswa kwe-electronZombili izindlela zisebenzisa ukushisa ukuncibilikisa ipulasitiki, okudala ijoyinti elihlala njalo, elingenamthungo eliqinile njengepayipi uqobo futhi elingavuzi nhlobo.

Sengichithe cishe amashumi amabili eminyaka ngikhiqiza izinhlelo zamapayipi, futhi ngizibonele mathupha ukuthi iphrojekthi ingaphumelela noma yehluleke kanjani ngokusekelwe emininingwaneni eyodwa encane: i-joint. Umphathi wokuthenga onjengoMinh eVietnam uyakwazi kahle lokhu. Akathengi nje ipayipi; uthenga isiqinisekiso sokuthi amanzi noma igesi kuzohlala ngaphakathi kwalo iminyaka engama-50 ezayo. Indlela esetshenziswa ukuxhuma lawo mapayipi iyingxenye ebaluleke kakhulu yaleso siqinisekiso. Yisihloko esifanele ukuqondwa ngokuningiliziwe, ngakho ake sihlaziye imibuzo evame kakhulu engiyithola kumakhasimende.

Ungakwazi yini ukuxhuma i-HDPE ku-PVC?

Udinga ukuxhuma umugqa omusha we-HDPE ohlelweni lwe-PVC olukhona. Ukushisela okuqondile kubonakala kulula, kodwa kuzohluleka, okubangela izithiyo zephrojekthi. Udinga ukufakwa okukhethekile kulo msebenzi.

Yebo, ungaxhuma i-HDPE ku-PVC, kodwa hhayi ngokuyishisela noma ngokuyinamathelisa. Kumelwe usebenzise i-mechanical transition fitting. Lokhu kudala uphawu oluqinile phakathi kwezinto ezahlukene, okuqinisekisa uxhumano oluqinile, olungavuzi ngaphandle kokushisa.

Awukwazi ukuhlanganisa i-HDPE ne-PVC ngoba ziyipulasitiki ezihlukene ngokuyisisekelo. Zinezinhlobo ezahlukene zamakhemikhali futhi ziyancibilika emazingeni okushisa ahlukene. Ukuzama ukuzishisisa nokushisa kufana nokuzama ukushisisa ukhuni nensimbi—akusebenzi. I-PVC ivame ukuhlanganiswa ne-solvent cement, okuyinqubo yamakhemikhali. Ukuhlanganisa i-HDPE kuncike ekuhlanganiseni ukushisa, inqubo esekelwe ekushiseni. Ukusebenzisa i-PVC solvent cement ku-HDPE ngeke kwenze lutho, futhi ukushisa okudingekayo ku-HDPE kuzobhubhisa i-PVC.

Isixazululo esifanele ukudala ijoyinti lomshini. Lokhu kuhlukanisa izinto ezimbili ngenkathi kunikeza uxhumano oluqinile noluvaliwe.

Ukufakwa Kokuguquka Okuyinhloko

1. Ama-adaptha e-Flange:Lena yindlela evame kakhulu yamapayipi amakhulu. I-adaptha ye-flange ye-HDPE ihlanganiswa nepayipi le-HDPE. I-flange ye-PVC inamathiselwa epayipini le-PVC. Bese kubekwa i-gasket phakathi kwama-flange amabili, bese ehlanganiswa ndawonye. Lokhu kudala uxhumano oluqinile olungahlukaniswa uma kudingeka.
2. Ama-adaptha e-Mechanical Joint (MJ):Lezi zihlanganisi zisebenzisa inhlanganisela yamabholidi nama-gasket okucindezela ukudala uphawu oluzungeze ingaphandle lepayipi. Zivame kakhulu ezinhlelweni zamanzi zikamasipala zokuxhuma ezintweni ezifana nama-valve ensimbi athambile noma imigqa ye-PVC ekhona.

Nasi incazelo elula ezokusiza ukuthi ukhethe:

Ngihlala ngiluleka amaklayenti ukuthi acabange ngesicelo. Kuphrojekthi enomfutho ophezulu, uxhumano olune-flange luthembekile futhi kulula ukuluhlola.

Iyini i-ejenti yokuhlanganisa ye-HDPE?

Uzwa igama elithi “i-coupling agent” bese ucabanga nge-glue. Ukusebenzisa i-glue ku-HDPE kuzodala isibopho esibuthakathaka esihluleka ngokushesha. Udinga ukuqonda ukuthi i-HDPE isebenzisa isimiso esihlukile ngokuphelele.

Amapayipi e-HDPE awasebenzisi i-chemical coupling agent noma iglue. “I-agent” ewahlanganisayo ukushisa. Izindlela zokuhlanganisa ezifana ne-butt fusion noma i-electrofusion zisebenzisa ukushisa okulawulwa ngokunembile ukuze kuncibilikiswe iziphetho zamapayipi, bese kuhlangana ndawonye njengoba zipholile.

Igama elithi “i-coupling agent” livame kakhulu ezimbonini ezisebenza ngezinto ezihlanganisiwe noma izinamathiseli. Ezweni lamapayipi e-HDPE, liyigama elidukisayo. Asifaki into yokubopha amapayipi; sishintsha isimo sezinto zamapayipi uqobo. I-HDPE iyi-thermoplastic, okusho ukuthi ungayincibilikisa bese uyivumela ukuthi iphole ukuze ulungise isiqina esinamandla. Lesi sici siyinzuzo yayo enkulu.

Ukushisa “yi-Agent” Yangempela

Uma ufaka ukushisa ngendlela efanele ezindaweni ezimbili ze-HDPE, amaketanga e-molecule avela kuzo zombili izingcezu ayahlangana. Njengoba izinto ziphola ngaphansi kwengcindezi, la maketanga ayahlangana. Umphumela awukho izingcezu ezimbili zepayipi ezinamathelana ndawonye; kuyipayipi elilodwa elilodwa, eliqhubekayo. Lokhu sikubiza ngokuthi i-monolithic joint ngoba isibe isakhiwo esisodwa esiqinile. Yingakho i-joint ehlanganiswe kahle inamandla, noma iqine kakhulu, kunodonga lwepayipi lokuqala. Akukho ndawo ebuthakathaka.

Kungani Ikhwalithi Yezinto Ezibalulekile Ibalulekile

Yilapho ulwazi lwami njengomkhiqizi luba lubalulekile khona kumakhasimende ami. Le nqubo yokuhlanganisa isebenza kahle kuphela uma izinto zokusetshenziswa zisezingeni eliphezulu futhi zihambisana. Sisebenzisa i-resin ye-PE100 engu-100% kuphela. Lokhu kuqinisekisa ukuthi lapho uchwepheshe endaweni yephrojekthi esebenzisa ukushisa, izinto zizoncibilika futhi zihlangane njengoba nje imininingwane yobunjiniyela ibikezela. Uma umenzi esebenzisa izinto ezisetshenziswe kabusha noma i-resin esezingeni eliphansi, amaphuzu okuncibilika angaba angaguquguquki, okuholela ekuhlanganeni okubuthakathaka noma okuhlulekile, kungakhathaliseki ukuthi umqhubi unekhono kangakanani. Ikhwalithi "ye-agent" - ukushisa - ayisebenzi uma izinto ngokwazo zinephutha.

Uhlobo luni lokuxhuma olusetshenziswa kumapayipi e-HDPE?

Iphrojekthi yakho idinga amajoyinti athembekile, angavuzi. Ukukhetha indlela engalungile yokuhlanganisa kungalimaza ubuqotho bohlelo lonke. Kumelwe uvumelanise le ndlela nezidingo ezithile zephrojekthi ukuze uthole umphumela ohlala njalo.

Izinhlobo eziyinhloko zokuxhumanisa amapayipi e-HDPE ukuhlanganiswa kokushisa kanye nokuxhumeka komshini. Ukuhlanganiswa kokushisa, okuhlanganisa ukuhlanganiswa kwe-butt kanye nokuhlanganiswa kwe-electro, kudala amalunga ahlala njalo. Ukufakwa komshini kusetshenziselwa ukushintsha noma lapho kungase kudingeke ukuhlukaniswa.

Eminyakeni edlule, ngihlinzeke ngamapayipi emisebenzi eminingi, kusukela emigodini emikhulu yamanzi kamasipala kuya ezitshalweni zokucubungula izimboni. Ukukhetha indlela yokuhlanganisa kuhlale kuyiphuzu elibalulekile lengxoxo. Isinqumo sincike kusayizi wamapayipi, izimo zendawo, izilinganiso zokucindezela, kanye nekhono leqembu lokufaka. Ukuqonda izinketho eziyinhloko kubalulekile kunoma yimuphi umphathi wokuthenga noma unjiniyela.

Izindlela Zokuhlanganisa Ukushisa

• Ukuhlanganiswa Kwezinqe:Lena yindlela evame kakhulu yamapayipi angu-63mm nangaphezulu. Le nqubo ihilela ukubheka iziphetho zamapayipi ukuze zihlanzeke ngokuphelele futhi zibe yisikwele, zifudumale ngepuleti ekhethekile, bese zicindezelwa ndawonye ngaphansi kwengcindezi elawulwayo. Lokhu kudala ukushintshwa okuqinile, okuhlala njalo. Kulungele amapayipi amade, aqondile.
• Ukuhlanganiswa kwe-Electro:Le ndlela isebenzisa izinto ezikhethekile ezifakwe ama-heating coil akhelwe ngaphakathi. Amapayipi afakwa ku-fitting, bese umshini udlulisa ugesi ngama-coil. Lokhu kuncibilikisa ingaphakathi le-fitting kanye nengaphandle lepayipi, kuhlanganiswe ndawonye. Ilungele ukulungiswa, ukusebenza emiseleni eqinile, noma ukuxhumanisa imigqa yamagatsha.

Izindlela Zokuxhumanisa Ngomshini

• Ukuxhumeka kwe-Flange:Njengoba kuxoxwe ngakho ngaphambili, lezi zinhle kakhulu ekuxhumeni i-HDPE kwezinye izinto noma imishini efana namaphampu namavalvu.
• Ukufakwa Kokucindezela:Lezi zivame kakhulu kumapayipi amancane anobubanzi (ngokuvamile angaphansi kuka-110mm), ikakhulukazi ekuniseleni. Zisebenza ngokuqinisa i-nut ecindezela indandatho kanye ne-gasket epayipini, okwenza kube nokuvala okungangeni manzi.

Ngihlala ngitshela amaklayenti ami ukuthi ngengqalasizinda ebalulekile yesikhathi eside, ukuhlanganiswa kokushisa kuyindlela engcono kakhulu. Kususa izindawo ezingaba khona zokuvuza ezikhona ngama-gasket nama-bolts omshini.

Ungahlanganisa kanjani ipayipi le-HDPE?

Unemishini efanele, kodwa iphutha elilodwa elincane lingalimaza ijoyinti. Inqubo ephuthumayo noma engcolile izoholela ekwehlulekeni kamuva. Ukulandela inqubo efanele isinyathelo ngesinyathelo kuyindlela kuphela yokuqinisekisa ukushintshwa okuqinile.

Ukuze uhlanganise ipayipi le-HDPE kanye ne-butt fusion, kufanele uhlanze futhi ubheke iziphetho, uzihlele kahle emshinini, uzifudumeze kuze kube yilapho kwakheka ubuhlalu, bese uzicindezela ndawonye ngaphansi kwengcindezi kuze kube yilapho ziphola ngokuphelele.

Ngokombono wami wokukhiqiza, ngibona ipayipi njengengxenye nje yomkhiqizo wokugcina. Ingxenye yesibili yikhwalithi yokufakwa. Ipayipi ephelele ingonakaliswa yijoyinti elibi. Ngake ngavakashela indawo eNingizimu-mpumalanga ye-Asia lapho abasebenzi babenenkinga yokushisela okuhlulekile. Inkinga kwakungeyona ipayipi noma umshini; babeqa isinyathelo sokuhlanza. Uthuli oluncane lwalungena kushisela futhi ludala indawo ebuthaka. Sababonisa inqubo efanele, futhi izinkinga zaphela ngokushesha. Kumphathi onjengoMinh, ukuqinisekisa ukuthi amaqembu akhe alandela lezi zinyathelo kubaluleke njengokuthola ipayipi elisezingeni eliphezulu.

Inqubo Yokuhlanganisa Izinqe: Isinyathelo Ngesinyathelo

1. Hlanza Ipayipi:Sula ingaphakathi nengaphandle lazo zombili iziphetho zamapayipi. Sebenzisa i-indwangu engena-lint kanye nesihlanzi esivunyelwe njenge-isopropyl alcoholNoma yikuphi ukungcola, umswakama, noma uwoyela kuzobhubhisa ubuqotho be-weld.
2. I-Climp kanye ne-Align:Vikela amapayipi emshinini wokuhlanganisa. Hlanganisa iziphetho ukuze uhlole ukulingana kwawo. Kumelwe zihlangane kahle ngaphandle kwezikhala.
3. Bhekana Neziphetho Zepayipi:Sebenzisa ithuluzi lomshini lokugunda izinwele ukuze uchebe inani elincane lezinto ezisuka ekugcineni ngakunye. Lokhu kudala izindawo ezintsha, ezihlanzekile, nezihambisana kahle zokushisela. Susa i-facer ngaphandle kokuthinta iziphetho ezisanda kubukeka.
4. Ncibilikisa Iziphetho:Hlola ipuleti lesifudumezi ukuqinisekisa ukuthi lisezingeni lokushisa elifanele usayizi wepayipi lakho kanye nobukhulu bodonga. Faka ipuleti phakathi kwamapayipi bese uwacindezela kulo kuze kube yilapho ungqimba olucacisiwe lwepulasitiki encibilikisiwe luvela ekugcineni ngakunye.
5. Joyina bese upholile:Susa ngokushesha ipuleti lesifudumezi bese uhlanganisa iziphetho zepayipi elincibilikisiwe ngaphansi kwengcindezi yokuhlanganisa echaziwe. Bamba le ngcindezi isikhathi sokupholisa esidingekayo. Ungasheshi lesi sinyathelo. Ijoyinti kumele iphole ngokuphelele ukuze ithole amandla ayo aphelele. Ukushintshwa okufanele kuboniswa ubuhlalu obufanayo, obuphindwe kabili obuzungeza ijoyinti.
