Ubona i-PE80 ne-PE100 ezicacisweni zobuchwepheshe. Izinombolo zihlukile, kodwa akucaci ukuthi lokhu kusho ukuthini ngephrojekthi yakho. Lokhu kudideka kungaholela ekukhetheni inketho ebuthakathaka noma ebiza kakhulu.

Umehluko omkhulu amandla. I-PE100 ine-Minimum Required Strength (MRS) ephakeme ngo-25% kune-PE80. Lokhu kuvumela amapayipi e-PE100 ukuthi abe nezindonga ezincane kakhulu ezinesilinganiso esifanayo sokucindezela, okwenza kube lula, kube nezindleko ezingcono, futhi kunikeze amandla okugeleza angcono.

Lokhu akuyona nje imininingwane emincane yobuchwepheshe; kuyintuthuko eyisisekelo kwisayensi yezinto ezibonakalayo enezinzuzo ezinkulu ezisebenzayo. Njengomkhiqizi, ngingakutshela ukuthishintsha kusuka ku-PE80 kuya ku-PE100njengoba indinganiso yemboni yayiyisinyathelo esikhulu sokuqhubekela phambili. Umphathi wokuthenga ohlakaniphile njengo-Arief e-Indonesia uyaqonda lokhu ngokushesha. Uyabona ukuthi i-PE100 imvumela ukuthi alethe ukusebenza okufanayo ngomkhiqizo osebenza kahle, olula, futhi olula ukuwufaka. Umehluko phakathi kwala mabanga amabili uthinta konke kusukela kwisabelomali sephrojekthi kuya ekuthembekeni kwesikhathi eside kwesistimu yonke.

Ingakanani ipayipi le-PE100?

Udinga ipayipi lephrojekthi yakho, kodwa uyazibuza ukuthi i-PE100 iza ngosayizi owudingayo. Lokhu kungaqiniseki kungenza kube nzima ukucacisa izinto zokwakha nokuhlela ipayipi lephrojekthi yakho ngempumelelo.

Ipayipi le-PE100 litholakala ngobubanzi obukhulu bosayizi abajwayelekile, kusukela kobubanzi obuncane obungu-20mm kuya kobubanzi obukhulu obungu-2500mm. I-PE100 iyizinga lezinto ezibonakalayo, hhayi usayizi, ngakho-ke ingakhiqizwa cishe kunoma yisiphi isayizi esidingekayo kunoma yisiphi isicelo.

Iphuzu elivamile lokudideka ukucabanga ukuthi i-“PE100” ibhekisela kusayizi. Kubalulekile ukukhumbula ukuthi i-PE100 iyizinga lezinto ezibonakalayo. Embonini yami, sisebenzisa leli zinga elilodwa lokusebenza kahle ukukhiqiza izinhlobo eziningi zosayizi bamapayipi. Simane sishintshe ama-extrusion dies ukuze sakhe amapayipi kusuka ku-20mm kuya ku-800mm noma ngaphezulu. Ububanzi obuncane, ngokuvamile obufika ku-110mm, bunganikezwa ngo-ama-coil amade, okunciphisa kakhulu inani lamalungu adingekayo ukuze kufakwe. Amadayamitha amakhulu akhiqizwa ngobude obuqondile, ngokuvamile amamitha ayi-6 noma ayi-12 ubude. Usayizi owudingayo cishe uyatholakala, ngoba izinto ngokwazo ziyaguquguquka kakhulu. Zingashintshwa ukuze zivumelane nanoma yini kusukela emzileni wamanzi omncane wezindlu kuya emzileni omkhulu wokuhambisa amanzi kamasipala.

Osayizi bepayipi le-PE100 elivamile kanye nezicelo

Yini enamandla, i-PE noma i-PVC?

Udinga ukukhetha phakathi kwe-PE ne-PVC, futhi kokubili kubizwa ngokuthi “okuqinile”. Kunzima ukwazi ukuthi iyiphi impahla eqinile ngempela futhi efaneleka kangcono izidingo zokufakwa kwakho.

Kuncike ekutheni uchaza kanjani amandla. I-PVC iqinile futhi inamandla aphezulu okubamba. Kodwa-ke, i-HDPE (PE) iguquguquka kakhulu futhi inamandla aphezulu kakhulu okuthonya, ikakhulukazi uma kubanda. I-HDPE ingagoba futhi ithathe amagalelo angaphula i-PVC.

Uma onjiniyela bekhuluma “ngamandla,” basho izakhiwo eziningana ezahlukene. I-PVC iqinile kakhulu. Lokhu kusho ukuthi imelana nokugoba, okungaba usizo kwezinye izinhlelo zokusebenza ezingaphezulu komhlaba lapho ungafuni khona ukuthi ipayipi ligobe. Kodwa-ke, lokhu kuqina okufanayo kwenza i-PVC ibe buthaka. Ukushaya okubukhali okuvela edwaleni ngesikhathi sokugcwalisa emuva, noma ngisho nokuwa ngesikhathi sokufakwa kwesimo sezulu esibandayo, kungabangela ukuthi iqhekeke noma iqhekeke. I-HDPE iphambene nalokho. Iguquguquka futhi iyamangalisaukumelana nomthelela. Ungayishaya ngesando, futhi cishe izovele iqhekezeke. Lokhu kuqina kuyenza ikwazi ukubekezelela kakhulu ngesikhathi sokufakwa kanye nokukhetha okuhlala isikhathi eside kwamapayipi agqitshwe. Ingakwazi ukuguquguquka ngokuhamba komhlabathi noma ukuhlala phansi ngaphandle kokuphuka, okuyinzuzo enkulu yokuthembeka kwesikhathi eside.

Izakhiwo Zamandla: I-HDPE vs. I-PVC

Kungani usebenzisa i-HDPE kune-PVC?

Uyabona ukuthi i-PVC ivame ukushibhile futhi itholakala kalula. Uzibuza ukuthi kungani umuntu engakhetha i-HDPE. Ngaphandle kokubona izinzuzo, ukusebenzisa i-HDPE kungabonakala njengezindleko ezengeziwe ezingadingekile.

Sebenzisa i-HDPE ngaphezu kwe-PVC ukuze uthole amajoyinti ayo angavuzi, ukuguquguquka okuphezulu, kanye nokuqina okukhulu. Lezi zici ziyenza ibe yindawo ekahle yokufaka ngaphandle kwemisele, imelane nokunyakaza komhlabathi, kanye nesisombululo sesikhathi eside esithembeke kakhulu esiqeda ukulahleka kwamanzi emajoyintini avuzayo.

Isizathu esikhulu sokukhetha i-HDPE yindlela yokujoyina. Amapayipi e-HDPE ayindlela yokuhlanganisa.kuhlanganiswe ukuhlanganiswa kokushisa, encibilikisa iziphetho zepayipi ndawonye ukuze kwakheke ingxenye eyodwa yepulasitiki eqhubekayo, eyodwa. Ijoyinti liqinile njengepayipi uqobo futhi ngeke livuze. I-PVC ithembele kuma-gasket noma kusimende we-solvent, okudala amaphuzu abuthakathaka emgqeni angawa ngokuhamba kwesikhathi. Kumasevisi amanzi, la majoyinti avuzayo angumthombo omkhulu wokulahleka kwamanzi. Okwesibili ukuguquguquka. Ukuguquguquka kwe-HDPE kuvumela ukuthi ifakwe ngeubuchwepheshe obungenamisele njengokubhoboza okuqondile (i-HDD)Lokhu kusho ukuthi ungafaka ipayipi ngaphansi komfula noma umgwaqo omatasa ngaphandle kokumba umsele omkhulu. Lokhu konga isikhathi esiningi nemali ekumbeni nasekuvuseleleni. Lezi zinzuzo zinikeza inani lesikhathi eside elidlula kakhulu noma yimuphi umehluko omncane wokuqala ezindleko zezinto zokwakha.

Izinzuzo Eziyinhloko ze-HDPE vs. PVC

Ungakwazi yini ukunamathisela i-HDPE ku-PVC?

Udinga ukuxhuma ipayipi elisha le-HDPE entanjeni ye-PVC ekhona. Uneglue ye-PVC esandleni sakho, kodwa awuqiniseki ukuthi izosebenza yini. Ukusebenzisa indlela engalungile yokuhlanganisa kungaholela ekuvuzeni okukhulu.

Cha, awukwazi nhlobo ukunamathisela i-HDPE ku-PVC. Izakhiwo zamakhemikhali ze-HDPE zivimbela noma yiluphi usimende we-solvent (glue) ukuthi luhlangane nobuso balo. Ukuze uhlanganise lezi zinto ezimbili, kumele usebenzise uxhumano olusebenza ngomshini njenge-flange assembly noma i-transition coupling ekhethekile.

Isizathu sokuthi awukwazi ukunamathisela i-HDPE yisona sizathu sokuthi imelana namakhemikhali. Isakhiwo sayo sama-molecule sizinzile kakhulu futhi asiyona i-polar, okusho ukuthi izinyibilikisi zivele zishelele ebusweni ngaphandle kokuyithinta. I-PVC glue isebenza ngokuncibilikisa ubuso be-PVC ngamakhemikhali ukuze ihlangane ndawonye. Le nqubo ayisebenzi ku-HDPE. Indlela ewukuphela kwayo elungile nethembekile yokuxhuma lezi zinto ezimbili ezahlukene ukusebenzisa i-mechanical fitting. Indlela evame kakhulu ukusebenzisa ama-flange. Sihlanganisa ama-butt-fuseI-adaptha ye-flange ye-HDPE (ebizwa nangokuthi ukuphela kwe-stub)epayipini le-HDPE. Bese unamathisela i-flange ye-PVC epayipini le-PVC. Ekugcineni, ubopha ama-flange amabili ndawonye nge-gasket yerabha phakathi ukuze wakhe uphawu olungangeni manzi. Kuyindlela elula, eqinile, nephephile esihlinzeka ngayo ngezinto zokufaka ngaso sonke isikhathi.

Izingxenye Zokuxhumanisa I-Flange ye-HDPE-kuya-kwi-PVC

Isiphetho

Umehluko phakathi kwe-PE80 ne-PE100 amandla, kanti i-PE100 ingcono kakhulu. I-HDPE iqinile futhi iguquguquka kakhulu kune-PVC, ihlanganiswe yi-fusion engavuzi, futhi kumele ixhunywe ngomshini.
