Ukhathazekile ngokwehluleka kwesistimu kumaphrojekthi akho okufaka amapayipi? Ukukhetha izinto ezingalungile kungaholela ekuvuzeni okubi kakhulu, ekulungisweni okubizayo, kanye nokonakala kwedumela.

Ukufakwa kwe-PPR kuyisixhumi esenziwe nge-Polypropylene Random Copolymer. Lezi zixhumi zisetshenziswa ngamapayipi e-PPR futhi zihlanganiswa ngenqubo yokuhlanganisa ukushisa, ehlanganisa ngempumelelo ipayipi futhi ihlanganiswe ibe yingxenye eyodwa, engenamthungo, futhi engavuzi unomphela.

Njengomuntu owakhe ibhizinisi ngokunikeza izixazululo zokuphathwa kwamanzi ezithembekile, ngiyaqonda ukubaluleka kwezingxenye ongazethemba. Umphathi wokuthenga onjengoCarlos akagcini nje ngokuthenga ingxenye; uthenga ukuthula kwengqondo kumakhasimende akhe. Ake sihlole ukuthi kungani i-PPR isibe yindlela ekhethwayo yokulungisa amapayipi esimanje.

Zisetshenziselwa ini izinto zokufakelwa ze-PPR?

Ingabe ufaka uhlelo lwamapayipi oludinga ukusingatha amanzi ashisayo nabandayo? Ukusebenzisa izinto ezingalinganiselwe amazinga okushisa aphezulu kuyinhlekelele elinde ukwenzeka.

Ukufakwa kwe-PPR kusetshenziselwa kakhulu izinhlelo zamanzi ashisayo nabandayo aphuzwayo emakhaya, emahhotela, ezibhedlela nasemahhovisi. Ukumelana kwawo namakhemikhali okuhle kakhulu kanye nokuqina kwawo kuwenza afanelekele ukuthuthwa koketshezi lwezimboni, izinhlelo zomoya ocindezelwe, ngisho nokuqoqwa kwamanzi emvula.

Ngikhumbula ngikhuluma nosonkontileka eMexico owayesakha ihhotela elisha. Wayekhathazekile ngezindleko zokulungisa zesikhathi eside ngenxa yokuvuza okungase kube khona ngaphakathi kwezindonga. Ngachaza ukuthi amalunga e-PPR ahlanganiswe nokushisa aqeda kanjani le ngozi. Kumphathi wokuthenga onjengoCarlos, ukukwazi ukunikeza lelo zinga lokuphepha kuyiphuzu lokuthengisa elinamandla. Kuguqula ingxoxo kusukela entengo iye enanini lesikhathi eside.

Amapayipi Ezindlu Nezebhizinisi

Lolu uhlelo lokusebenza oluhamba phambili. I-PPR ayigqwali noma ayivumeli i-limescale ukuthi yakheke, okusho ukuthi umfutho wamanzi ungcono futhi ugeleza kahle phakathi nesikhathi sokuphila kwesistimu. Le nto ayinabo ubuthi futhi iqinisekiswe ukuthi ingasetshenziswa emanzini okuphuza, okuqinisekisa impilo nokuphepha kwabasebenzisi bokugcina. Kwabaphangi, uhlelo olungakhiqizi ukuvuza okuhlobene nokuvuza luyigolide elicwengekile.

Izinhlelo Zomoya Ezicindezelwe kanye Ne-HVAC

Ezinhlelweni zokushisa, ukungenisa umoya, kanye nokupholisa umoya (i-HVAC),Amapayipi e-PPRzisetshenziselwa ukuthutha amanzi abandayo noma ashisayo. Ubuso bazo obubushelelezi bangaphakathi bunciphisa ukungqubuzana, buthuthukisa ukusebenza kahle kwamandla. Komoya ocindezelwe,imvelo engavuziUkuhlanganiswa kwamalunga ahlanganiswe nge-fusion kuyinzuzo enkulu. Ukuvuza emugqeni womoya ocindezelwe empeleni kuwukuvuza kwemali, ngakho-ke uhlelo oluvikelekile lunikeza ukonga okukhulu kokusebenza.

Ukusetshenziswa Kwezimboni Nezolimo

Ngenxa yokuthi i-PPR imelana namakhemikhali ahlukahlukene, iyisinqumo esithembekile sokuthutha uketshezi oluhlukahlukene emafektri. Kwezolimo, ingasetshenziswa ezinhlelweni zokunisela ezigcina ukushisa, ikakhulukazi lapho umanyolo uxutshwa khona emanzini, isimo lapho amapayipi ensimbi angagqwala ngokushesha.

Yikuphi okungcono, i-PPR noma i-PEX?

Ingabe impikiswano phakathi kokuqina kwe-PPR kanye nokuguquguquka kwe-PEX kubangela ukudideka? Ukukhetha okungalungile kungaholela ezindleleni zokufaka eziphezulu kanye nezinhlelo ezingasebenzi njengoba kulindelekile.

Akukho okuphakeme kakhulu emhlabeni wonke; bafeza izidingo ezahlukene. I-PPR inikeza ukugijima kwamapayipi okuqinile, okuqondile kanye namajoyinti aqinile kakhulu ahlanganiswe nokushisa. I-PEX iguquguquka kakhulu, ivumela ukufakwa okusheshayo eduze kwezithiyo ezinokufakwa okuncane. Ukukhetha okungcono kuncike ezintweni eziza kuqala kuphrojekthi kanye nokujwayelana kwabafaki.

Ngivame ukweluleka amakhasimende ukuthi acabange ngesikhathi eside. Uchwepheshe wamapayipi wake wangitshela ukuthi ukhetha i-PPR kumaphrojekthi okuhlala aphezulu ngoba imigqa eqinile ibukeka ichwepheshile futhi amajoyinti ahlanganisiwe azizwa ephephile kakhulu kuye. Nakuba i-PEX ishesha ukufakwa, uthengisa amakhasimende akhe ngokuthembeka kwe-PPR "yokungcwaba bese uyikhohlwa". KuCarlos, unikeza zombili izindlela anganakekela osonkontileka ababeka phambili isivinini kanye nalabo ababeka phambili ukuqina okubonakalayo.

Leli thebula lisiza ukucacisa ukuthi isinqumo siwukuhwebelana. Uma umsebenzi uhilela ukugijima okude nokuqondile esakhiweni esisha, ukuqina kwe-PPR kanye namandla amalunga kuhle kakhulu. Uma kuyisakhiwo esisha esinamakhona amaningi aqinile kanye nezakhiwo ezikhona zokuzulazula, ukuguquguquka kwe-PEX kungonga isikhathi esiningi kanye nomsebenzi.

Iyini inkinga ye-PPR?

Ingabe ucabanga nge-PPR njengesixazululo esiphelele sawo wonke amaphrojekthi akho? Ngaphambi kokuthi uzibophezele, kufanele uqaphele imikhawulo yayo ukuze ugweme izinkinga ezikhungathekisayo nezibizayo ngesikhathi sokufakwa.

Izinkinga eziyinhloko ze-PPR ukuqina kwayo, okudinga ukufakwa okwengeziwe kokujika, isidingo sethuluzi elikhethekile lokuhlanganisa ukushisa, kanye nokwandiswa kwayo okuqondile lapho ithwala amanzi ashisayo. Ayimelani nemisebe ye-UV futhi kumele ivikelwe elangeni.

Ukucaca ngemikhawulo yomkhiqizo kuyisihluthulelo sokwakha ukwethembana. Ngihlala ngiqinisekisa ukuthi abalingani abanjengoCarlos bayazi kahle lezi zici. Ukusingatha lezi zingqinamba kulula ngokuhlela kahle, futhi kukhombisa ukuthi umfaki unguchwepheshe wangempela. Isibonelo, ukwazi ukufaka iluphu yokwandisa emgqeni omude wamanzi ashisayo kuwuphawu lokufakwa kwekhwalithi.

Amathuluzi Nokuqeqeshwa Okukhethekile

Awukwazi ukuxhuma i-PPR ngeglue noma amathuluzi esandla alula. Kudinga i-insimbi yokushisela yokuhlanganisa ukushisaNakuba kungabizi kakhulu, kuyindleko yokuqala kunoma yimuphi umakhi oqala nge-PPR. Ngaphezu kwalokho, umqhubi udinga ukuqeqeshwa okuyisisekelo ukuze azi ukuthi uzofudumeza ipayipi isikhathi esingakanani futhi afake ukuze adale i-weld ephelele. “I-weld ebandayo” engahlanganiswanga ngokuphelele ingabangela ukwehluleka.

Ukuqina Nokwanda Kokushisa

Nakuba ukuqina kuyinzuzo yokugijima okuqondile, kuyiphutha lapho uhamba ezindaweni ezixineneyo. Ushintsho ngalunye endleleni ludinga ukufakwa kwendololwane. Okubaluleke kakhulu, njengazo zonke ipulasitiki, i-PPR iyakhula ngokushisa. Ekugijimeni isikhathi eside kwepayipi lamanzi ashisayo, "iluphu yokwandisa" noma i-offset kumele yakhelwe ohlelweni ukuze imunce lokhu kunyakaza futhi ivimbele ukucindezeleka epayipini nasezintweni ezifakiwe.

Ukuzwela kwe-UV

I-PPR ayiklanyelwe ukuchayeka ngqo elangeni. Imisebe ye-ultraviolet izokonakalisa impahla ngokuhamba kwesikhathi, yenze iqhekeke. Noma yikuphi ukufakwa kwangaphandle kwepayipi le-PPR kumele kupendwe ngombala okhanyayo,Upende ovimba i-UVnoma embozwe ngesivikelo. Lesi isinyathelo esilula kodwa esibucayi esingenakunganakwa.

Ingabe ukufakwa kwe-PPR kungcono kune-PVC?

Ingabe uyalingeka ukusebenzisa i-PVC ejwayelekile yomugqa wamanzi ashisayo ukuze wonge imali? Leli yiphutha eliyingozi elingaholela ekuqhekekeni kwamapayipi, ekulimaleni kwempahla, kanye nezinkinga zomthwalo wemfanelo.

Ekusetshenzisweni kwamanzi ashisayo, i-PPR ingcono kakhulu kune-PVC. I-PPR yenzelwe ukusingatha amazinga okushisa afinyelela ku-95°C (203°F), kuyilapho i-PVC ejwayelekile ingaqala ukuthamba nokuwohloka cishe ku-60°C (140°F), okwenza ingafaneleki nhlobo futhi ingaphephile emanzini ashisayo.

Njengomholi we-Pntek, inkampani eyaziwa ngemikhiqizo yayo ye-PVC esezingeni eliphezulu, ngingowokuqala ukusho: sebenzisa ithuluzi elifanele lomsebenzi ofanele. Sithengisa i-PVC ngalokho ekwenza kahle kakhulu—imisele yamanzi abandayo, ukuchelela, kanye nokugeleza kwamanzi. Ukuzama ukuyenza yenze umsebenzi engaklanyelwanga wona kuyindlela yokwehluleka. Ebhizinisini lakhe, uCarlos ukhonza amakhasimende akhe kangcono ngokugcina i-PVC yokusetshenziswa kwamanzi abandayo kanye ne-PPR yokufakwa kwamapayipi amanzi ashisayo.

Ukuqhathanisa Lapho Kubalulekile Khona

Ukukhetha phakathi kwe-PPR ne-PVC akukhona ukuthi yikuphi "okungcono" iyonke, kodwa ukuthi yikuphi okulungile ukusetshenziswa okuthile. Cishe njalo kuncike ekushiseni.
