Ingabe ubhekene nokuvuza noma izindawo ezibuthakathaka ohlelweni lwakho lwamapayipi? Ukusebenzisa ukufakwa okungafanele kwepayipi le-HDPE kuyimbangela evamile yokwehluleka kwesistimu okubizayo kanye nokubambezeleka kwephrojekthi.

Amapayipi e-HDPE axhunywe kusetshenziswa izinhlobo ezintathu eziyinhloko zokufakelwa:ukuhlanganiswa kwezinqe, ukuhlanganiswa kwe-electron, kanye nokufakwa kokucindezela komshini. Izindlela zokuhlanganisa zakha ijoyinti elihlala njalo, eliyi-monolithic eliqinile njengepayipi uqobo, kuyilapho ukufakelwa kokucindezela kunikeza uphawu olususwayo nolwemishini.

Ukwazi amagama ezinto zokufaka kumane kuyisiqalo. Umphathi wokuthenga osezingeni eliphezulu njengoCarlos uyaqonda ukuthi ubuchwepheshe bangempela busekwazini ukuthi yikuphi ukufakelwa okufanele ukusebenzisele yisiphi isimo. Lolu lwazi yilona oluvikela ukutshalwa kwezimali kwakho, luqinisekise ubuqotho bephrojekthi, futhi lwakhe idumela lokuthembeka.

Uxhumanisa kanjani amapayipi e-HDPE ndawonye?

Ingabe ubhekene nobunzima bokuxhuma amapayipi okuyinkimbinkimbi noma okungathembekile? Ijoyinti elibi liyisixhumanisi esibuthakathaka kakhulu kunoma yiluphi uhlelo lwamapayipi, elilindele ukubangela izinkinga esikhathini esizayo.

Uxhuma amapayipi e-HDPE ngokuwelda ukushisa (i-butt fusion noma i-electrofusion) ukuze uthole isibopho esihlala njalo, esingavuzi, noma ngezinsimbi zokucindezela ngomshini zamadayamitha amancane noma ukuxhumeka kwesikhashana lapho kungadingeki khona imishini ekhethekile. Indlela ngayinye inenhloso ehlukile.

Ngokwalokho engikubonile ePntek, ngizibonele mathupha ukuthi ukukhetha indlela efanele yokuxhuma kusindisa isikhathi nemali eningi endaweni. Lapho uCarlos esiza umakhi ukuthi akhethe phakathi kokufakwa okulula kokucindezela ukulungisa okuncane kanye nokuhlanganiswa kwezinqe zepayipi elikhulu, akagcini nje ngokuthengisa ingxenye; uthengisa ikhambi eliqinisekisa impumelelo yesikhathi eside.

Ukuhlanganiswa Kwezinqe

Lena yindlela evame kakhulu yamapayipi amakhulu e-HDPE. Inqubo ilula. Umshini okhethekile ubamba iziphetho ezimbili zamapayipi ziqonde kahle. Ipuleti lesifudumezi libekwa phakathi kwazo, lincibilikise iziphetho zibe yizinga lokushisa elithile. Ipuleti liyasuswa, bese iziphetho ezincibilikisiwe zicindezelwa ndawonye ngaphansi kwengcindezi elawulwayo. Ziyaphola ukuze zakhe ipayipi elilodwa, eliqhubekayo. Leli lunga alivuzi ngokuphelele futhi liqinile njengepayipi lokuqala.

Ukuhlanganiswa kwe-Electro

Le ndlela ilungele ukulungiswa noma ezindaweni eziqinile lapho umshini wokuhlanganisa izinqe ungangeni khona. Ama-electrofusion fittings ane-coil yocingo efakwe ngaphakathi kwawo. Iziphetho zamapayipi zifakwa ku-fitting, bese iprosesa ye-electrofusion ithumela ugesi ezintanjeni. Ukushisa okuvela ezintanjeni kuncibilikisa ingaphakathi le-fitting kanye nengaphandle lepayipi, kuzihlanganise ndawonye zibe yi-joint eqinile neqinile.

Ukufakwa Kokucindezela Kwemishini

Kuma-diameter amancane (ngokuvamile angaphansi kwama-intshi angu-4 noma angu-110mm), ukufakwa kokucindezela kuyisisombululo esihle kakhulu nesilula. Akudingi mishini ekhethekile. Umane uslayida inathi kanye nendandatho yokubamba phezu kwepayipi, ufake ipayipi emzimbeni wokufaka, bese uqinisa inathi. Lokhu kucindezela i-O-ring ukuze kudalwe uphawu olungangeni manzi. Kuyashesha, kulula, futhi kungenziwa yinoma yimuphi umsebenzi.

Ingabe i-HDPE ingcono kune-PVC?

Ingabe uphikisana phakathi kwe-HDPE ne-PVC ngephrojekthi yakho elandelayo? Ukukhetha izinto ezingalungile kungaholela ezinkingeni zokufakwa kanye nohlelo olungahlangabezani nokulindelwe kokusebenza.

Akukho okunye 'okungcono' emhlabeni wonke. I-HDPE ingcono ngenxa yokuguquguquka kwayo, ukumelana namakhemikhali, kanye nokuqina kokuncibilika nokuqandisa, okwenza ifaneleke kakhulu ekufakweni okungenamisele nasezimweni ezinzima. I-PVC ingcono ngenxa yokuqina kwayo, amandla aphezulu okudonseka, kanye nezindleko eziphansi, okwenza kube ukukhetha okuphezulu kokusetshenziswa kwamanzi amakhulu kanye nokucindezela.

Njengomholi we-Pntek, inkampani ehamba phambili ku-PVC, ngibone amaphrojekthi amaningi lapho i-PVC inikeza khona ibhalansi ephelele yokusebenza kanye nenani. Kodwa-ke, ngingowokuqala ukuvuma ukuthi i-HDPE iyithuluzi elifanele lomsebenzi. Uchwepheshe onjengoCarlos uyazi ukuthi indlela engcono kakhulu yokukhonza amakhasimende akhe ukubaqondisa ezintweni ezifanele izidingo zabo ezithile, hhayi nje ukusunduza umkhiqizo owodwa ngaphezu komunye.

Ukuzivumelanisa nezimo vs. Ukuqina

Umehluko osobala kakhulu ukuguquguquka. Ikhono le-HDPE lokugoba liyivumela ukuthi ifakwe emakhoneni ngaphandle kokufakwa okwengeziwe futhi lenza ifaneleke kakhulu ekufakweni ngaphandle kwemisele (ukuyidonsa emhlabathini). I-PVC iqinile kakhulu, okuyinika amandla aphezulu okubopha ukuze ingcwabe futhi ivimbele ukugoba lapho igijima isikhathi eside, iqondile.

Indlela Yokujoyina kanye Nezindleko

Lokhu kuyisici esikhulu kuCarlos namakhasimende akhe. I-PVC ihlanganiswe nama-primer alula, angabizi kanye ne-solvent cement, noma neziphetho zensimbi ezine-gasket. Amathuluzi alula futhi umsebenzi uyashesha. I-HDPE idinga imishini yokuhlanganisa ukushisa ebizayo, ekhethekile kanye nabaqhubi abaqinisekisiwe, okwandisa izindleko zephrojekthi yokuqala kanye nobunzima. Ngokuphathelene nezindleko zezinto, i-PVC ngokuvamile ishibhile kune-HDPE yesigaba esifanayo sokucindezela.

Ukuqhathaniswa Kohlelo Lokusebenza

Ingabe i-HDPE ilinganiswa nge-OD noma i-ID?

Ingabe uku-oda ipayipi elingalungile kungaphazamisa uhlelo lwakho lonke lwephrojekthi? Ukungaqondi kahle ukuthi ipayipi le-HDPE lilinganiswa kanjani kungaholela emapayipini nasezintweni ezingahambisani, kuchithe isikhathi nemali.

Ubukhulu bepayipi le-HDPE busekelwe kububanzi obungaphandle obulawulwayo (OD). Lokhu kubalulekile ngoba izindlela zokuxhumanisa zidinga ubuso bangaphandle bepayipi kanye nokufakwa ukuze kufane kahle ukuze kufakwe i-weld ephumelelayo.

Lena imininingwane yobuchwepheshe ehlukanisa abalimi abangochwepheshe. Uma ngikhuluma nomphathi wokuthenga onjengoCarlos futhi ecacisa ipayipi nge-OD ne-SDR yalo, ngiyazi ukuthi ngisebenzisana nochwepheshe. Uyaqonda ukuthi lokhu kunemba akuyona nje inombolo ephepheni lemininingwane; kuyisihluthulelo sesistimu ethembekile, engenawo amanzi. Ububanzi bangaphakathi (ID) buzoshintsha kuye ngokuthi udonga lubanzi kangakanani, kodwa i-OD ihlala ifana ngosayizi wepayipi elithile.

Kungani Ububanzi Bangaphandle Buyisihluthulelo

Ukuhlanganiswa kokushisa kusebenza ngokuncibilikisa ubuso bangaphandle bepayipi kanye nobuso bangaphakathi bepayipi (noma ubuso bangaphandle bepayipi). Ukuze lokhu kusebenze, ubuso kumele buvumelane kahle. Ngokugcina i-OD ingaguquki, abakhiqizi baqinisekisa ukuthi noma yiliphi ipayipi losayizi othile lizolingana nanoma yimuphi umshini wokuhlanganisa noma wokuhlanganisa ohambisanayo, kungakhathaliseki ukuthi ungakanani umfutho wawo.

Ukuqonda i-SDR (Isilinganiso Esijwayelekile Sobukhulu)

• Kuyini:I-SDR iyisilinganiso sobubanzi bangaphandle bepayipi nobukhulu bodonga lwayo.
• Ifomula:I-SDR = OD / Ubukhulu Bodonga
• Kusho ukuthini: A phansiInombolo ye-SDR isho i-akhuluudonga lwamapayipi. Udonga olujiyile lungaphatha ukucindezela okuphezulu. Isibonelo, ipayipi le-SDR 11 linodonga olujiyile kanye nesilinganiso sokucindezela esiphezulu kunepayipi le-SDR 17 elinobukhulu obufanayo. UCarlos udinga ukwazi kokubili i-OD edingekayo kanye ne-SDR ukuze a-ode ipayipi elifanele izidingo zokucindezela kwamakhasimende akhe.

Hlobo luni lwejoyinti olusetshenziswa epayipini le-HDPE?

Ingabe ufuna ipayipi ongalifihla bese ulikhohlwa? Ukwesaba ukuvuza kwesikhathi esizayo okuvela emajoyintini angcwatshiwe kuyinto ekhathaza kakhulu osonkontileka kanye nabanikazi bezinhlelo.

Ijoyinti eliyinhloko neliqine kakhulu elisetshenziswa epayipini le-HDPE yijoyinti yokuhlanganisa izinqe. Le nqubo yokushisela ukushisa idala uxhumano olungenamthungo (olungenamthungo) olungavuzi nhlobo futhi oluvame ukuba namandla kunepayipi uqobo.

Umqondo wesistimu "efanayo" ushintsha umdlalo. Kusho ukuthi empeleni udala ipayipi elilodwa elide, eliqhubekayo elingenazo izixhumanisi zemishini ezingakhululeka noma zonakale ngokuhamba kwesikhathi. Kumthengi onjengoCarlos, ukukwazi ukunikeza uhlelo oluqeda ingozi yokuwa kwamalunga kuyinzuzo enkulu yokuncintisana. Kuyisithembiso sokugcina sokuthembeka kwesikhathi eside.

Ukudala Uhlelo Olungavuzi Ngempela

Ijoyinti elihlanganiswe nezinqe alifani noxhumano olunamathelisiwe noma oluboshwe; liwukwakhiwa kabusha kwezinto ngokwazo. Amaketanga e-polymer avela kuzo zombili iziphetho zamapayipi ahlangana ndawonye esimweni sawo esincibilikisiwe futhi apholile ukuze akhe ingxenye eyodwa eqinile. Ubuhlalu obuncane obakheka ngaphakathi nangaphandle kwepayipi buyisibonakaliso esibonakalayo se-weld ephumelelayo. Leli joyinti lihlanganiswe kangangokuthi ligcina ukuguquguquka namandla epayipi ngokuphelele.

Kungani Lokhu Kuyi-Gold Standard

Lolu hlobo lwejoyinti luthembeke kakhulu kangangokuthi luyindinganiso yezicelo ezibalulekile njengemigqa yokusatshalaliswa kwegesi yemvelo, imigudu yamanzi enomfutho ophezulu, kanye nokuthuthwa kwamakhemikhali ezimbonini. Ijoyinti liyazibamba ngokuphelele, okusho ukuthi alikwazi ukuhlukana ngaphansi kwengcindezi noma ukunyakaza komhlaba. Lokhu kuqeda isidingo samabhulokhi noma izivimbelo ezibizayo ezidingekayo kwezinye izinhlelo eziningi zamapayipi, okunciphisa kakhulu izindleko zokufaka kanye nobunzima.

Isiphetho

Izinhlelo ze-HDPE zithembele ekuhlanganiseni nomaukufakwa kokucindezelwa. Ukuhlanganiswa kwezinqe kudala ijoyinti eliqine kakhulu, elingavuzi. Ukukhetha phakathi kwe-HDPE eguquguqukayo ne-PVC eqinile nengabizi kakhulu kuncike ngokuphelele ezidingweni ezithile zephrojekthi.
