Amajoyinti emishini ohlelweni lwakho lwamapayipi ahlala ebonakala sengathi yiwona maphuzu okuqala okwehluleka. I-gasket evuzayo noma i-nut yokucindezela ekhululekile ingabangela umonakalo omkhulu, ukulungiswa okubizayo, kanye nesikhathi sokungasebenzi kohlelo.

Ukufakwa kwe-socket fusion kuyi-thermoplastic fitting (njenge-HDPE noma i-PP-R) ehlanganiswa nepayipi ngokushisela ukushisa. Ithuluzi elikhethekile lincibilikisa ingaphandle lepayipi kanye nengaphakathi le-fitting, bese licindezelwa ndawonye ukuze lenze ucezu olulodwa, oluhlala njalo, olungavuzi.

Ngikhumbula ngikhuluma neklayenti elaliphethe iphrojekthi enkulu yokunisela. Wayehlala ebhekene nokuvuza okuvela ezingxeni zemishini zendabuko ezibangelwa ukuhamba komhlaba kanye nokushintsha kwengcindezi yamanzi. Lapho ngimethula umqondo wokuthiukuhlanganiswa kwesokhethi, kwaba yinto eshintsha umdlalo. Umqondo wokuthi ijoyinti lingaqina njengepayipi uqobo, noma liqine kakhulu kunepayipi uqobo lwalo uxazulule inkinga yakhe enkulu yokwethembeka. Kuwubuchwepheshe obulula, kodwa uma uqonda ukuthi busebenza kanjani, ubona izinzuzo zalo ezinkulu. Ake sihlole imininingwane.

Yini ngempela i-PE fitting eyenziwe ngayo?

Ubona igama elithi “PE” ekufakweni kodwa awazi ukuthi lisho ukuthini ngamandla. Ukukhetha ukufakwa okwenziwe ngepulasitiki engalungile kungaholela ekuhlulekeni okungalindelekile ngaphansi kwengcindezi.

Ukufakwa kwe-PE kwenziwa nge-polyethylene. Uma kufakwa amapayipi okucindezela, lokhu cishe njalo kuyi-High-Density Polyethylene (HDPE), into eqinile, eguquguqukayo, futhi engamelani namakhemikhali efanele ukusetshenziswa okudingakalayo njengokusatshalaliswa kwamanzi negesi.

I-Polyethylene iyiqembu lamapulasitiki, kodwa akuzona zonke izinhlobo ezidalwe zilingana. Isihluthulelo ubuningi. Uma ubuningi buphakeme, kulapho izinto ziqina futhi ziqine khona. Ngezihlanganisi zokuhlanganisa amasokhethi ezisetshenziswa emanzini amakhulu noma emapayipini ezimboni, sisebenzisaI-HDPE, evame ukubizwa ngokuthi i-PE100. Leli banga linesisindo esikhulu kakhulu sama-molecule, okwenza likwazi ukumelana kahle nengcindezi, imithelela, kanye namakhemikhali. Liyinto efanayo esetshenziswa amapayipi ngokwawo. Lokhu kuqinisekisa ukuthi uma uhlanganisa i-Pntek PE efanelana nepayipi le-PE, uhlanganisa izinto ezimbili ezifanayo. Lokhu kuhambisana kuyisisekelo sokudala i-weld ephelele, ye-monolithic ezohlala amashumi eminyaka ngaphandle kokuwohloka. Liyinto eyenzelwe ukuphepha kwesikhathi eside.

Izinhlobo Ezivamile Ze-Polyethylene

Yiziphi izinhlobo zamapayipi ongazihlanganisa ne-PE fusion?

Unethuluzi lokuhlanganisa, kodwa awuqiniseki ukuthi yiziphi izinhlobo zamapayipi epulasitiki elisebenza ngazo. Ukuzama ukuhlanganisa izinto ezingahambisani kuzoholela ekuqhekekeni ngokuphelele kwejoyinti.

I-PE fusion isetshenziselwa ukuhlanganisa izinto ezifanayo ze-thermoplastic. Yakhelwe ngqo amapayipi e-polyethylene (PE) njenge-HDPE ne-MDPE, kanye namapayipi e-polypropylene (PP-R). Awukwazi ukuhlanganisa amapulasitiki ahlukene njenge-PE ne-PVC.

Isimiso se-ukushisela ukuhlanganiswaKulula: uncibilikisa futhi uphinda wakhe ipulasitiki. Ukuze lokhu kusebenze, izingxenye ezimbili ozihlanganisayo kumele zibe nokwakheka kwamakhemikhali okufanayo kanye nokushisa kokuncibilikisa. Yingakho ungahlanganisa kuphela "ukuthanda nokufana." Isicelo esivame kakhulu ukujoyinaIpayipi le-HDPEkuya ku-HDPE fittings yezinhlelo ezidinga ukuthembeka okuphelele. Lokhu kufaka phakathi imigodi yamanzi kamasipala egqitshwe ngaphansi komhlaba, imigqa yamakhemikhali yezimboni enomfutho ophezulu, kanye namanethiwekhi okusabalalisa igesi yemvelo. Inqubo efanayo yokuhlanganisa amasokhethi iyindlela ejwayelekile yokuhlanganisa amapayipi e-PP-R, athandwa kakhulu ngamapayipi amanzi ashisayo nabandayo ngaphakathi kwezakhiwo. Okubalulekile ukuthi ukuhlanganisa kudala uhlelo olungenamthungo, kodwa kuphela uma ipayipi nezinto zokufaka zihambisana kahle.

Uhlanganisa kanjani amapayipi e-HDPE kanye nezinto zokufakelwa ndawonye?

Inqubo yokushisela i-fusion ingabonakala iyinkimbinkimbi. Ukunyakaza okukodwa okungalungile, futhi ungakha ijoyinti elibuthakathaka elihluleka kamuva, liqede ukuzethemba emsebenzini wakho wokufaka.

Ukuze uhlanganise i-HDPE, ufudumeza indawo yangaphandle yepayipi kanye nendawo yangaphakathi yokufakwa ngethuluzi isikhathi esithile. Bese, uzicindezela ndawonye bese uzibamba kuze kube yilapho zipholile. Lokhu kudala ijoyinti elihlala njalo, elihlanganisiwe.

Inqubo iqondile kodwa iqondile uma ulandela izinyathelo.

1. Ukulungiselela:Okokuqala, sika ingxenye yepayipi ibe yizikwele ngokuphelele. Bese uhlanza ingxenye yepayipi kanye nengaphakathi lesokhethi elifanele ukuze ususe noma yikuphi ukungcola noma amafutha.
2. Ukushisa:Ithuluzi lokuhlanganisa ama-socket linama-adapter okushisa osayizi abahlukene bamapayipi. Phusha ipayipi ohlangothini olulodwa bese ufaka kwelinye uhlangothi ngesikhathi esisodwa. Isikhathi sokushisa sibalulekile futhi sincike kububanzi bepayipi.
3. Ukujoyina:Uma isikhathi sokushisa sesiphelile, susa ngokushesha nangokushelela izingxenye zombili ethuluzini. Phusha ipayipi ngokushesha liqonde ngqo kusokhethi yokufakwa kuze kube yilapho liyeka. Ungalijiki.
4. Ukupholisa:Bamba ijoyinti linganyakazi kahle isikhathi esibekiwe sokupholisa. Lokhu kuvumela ipulasitiki encibilikisiwe ukuthi iqine ibe yingcezu eyodwa eqinile.

Ukulandela izikhathi ezifanele zokushisa nokupholisa kubalulekile ukuze kube nokushibilika okuthembekile.

Kungani i-fusion fitting inamandla kune-mechanical joint?

Usebenzisa izinto zokufakelwa ngomshini ngoba kulula ukuzifaka. Kodwa uyazi ukuthi yonke i-gasket nayo yonke intambo iyindawo engase yehluleke engakhululeka ngokuhamba kwesikhathi.

Ukufakwa kwe-fusion kunamandla kakhulu ngoba kususa ngokuphelele ijoyinti. Ipayipi kanye nokufakwa kuba yingcezu eyodwa eqinile yepulasitiki. Lokhu kuxhumeka kwe-monolithic akunawo ama-gasket okudiliza noma amabhawodi okuxegisa, okwenza kube namandla kunepayipi uqobo.

Ijoyinti yomshini ixhumanisa izingxenye ezimbili, kodwa i-fusion weld iyawahlanganisa. Cabanga ngeketanga lensimbi; liqinile njengesixhumanisi salo esibuthakathaka kakhulu. Ephayiphini elinezihlanganisi zomshini, amajoyinti ayizixhumanisi ezibuthakathaka. Athembele ekucindezelweni kwe-gasket yerabha noma ukungqubuzana kwemicu ukuze adale uphawu. Lokhu kungathinteka ukudlidliza, izinguquko zokushisa, kanye nokunyakaza komhlabathi. I-fusion weld ayinabo lobu buthakathaka. Inqubo yokuncibilikisa nokwakha kabusha i-HDPE isho ukuthi indawo yejoyinti iba yibhulokhi eqinile yepulasitiki engenamthungo. Uma senza izivivinyo zokucindezela okuqhumile elabhorethri yethu, udonga lwamapayipi luzohlala luhluleka ngaphambi kokuba ijoyinti elihlanganisiwe lenze njalo. Yingakho ngezicelo ezibucayi, zokubekezelela ukuvuza okungcwatshwe ngaphansi komhlaba noma ezifakwe kukhonkolo, i-fusion iyona kuphela inketho ethembekile ngempela.

Ama-Fusion vs. Ama-Mechanical Joints

Isiphetho

Ukuhlanganiswa kwesokhethi kudala ijoyinti elihle kakhulu ngokuhlanganisa ipayipi bese kufakwa engxenyeni eyodwa eqinile. Lokhu kususa amaphuzu okuvuza, okwenza kube yindlela ethembeke kakhulu yezinhlelo ze-PE kanye ne-PP-R.
