Iiprojekthi zokunkcenkceshela ngumsebenzi othatha ixesha elininzi onokubiza kakhulu ngokukhawuleza. Indlela entle yokonga imali kwiprojekthi yokunkcenkceshela kukusebenzisa umbhobho wePVC kumbhobho wesebe, okanye umbhobho ophakathi kwevalvu kumbhobho wamanzi ophambili kunye ne-sprinkler. Nangona umbhobho wePVC usebenza kakuhle njengezinto ezinqamlezileyo, uhlobo lombhobho wePVC olufunekayo luyahluka ngokwemisebenzi. Xa ukhetha ukuba yeyiphi imibhobho oza kuyisebenzisa emsebenzini wakho, kubalulekile ukuqinisekisa ukuba uthatha ingqalelo kwizinto zangaphandle ezifana noxinzelelo lwamanzi kunye nokukhanya kwelanga. Ukukhetha uhlobo olungalunganga kunokukhokelela kulondolozo oluninzi olongezelelekileyo nolungafunekiyo. Iposi yebhlog yale veki igubungela iintlobo eziqhelekileyo zemibhobho yokunkcenkceshela yePVC. Lungela ukonga ixesha, amanzi kunye nemali!

IShedyuli 40 kunye neShedyuli 80 yePipe yePVC Umbhobho wePVC
Xa ukhetha imibhobho yokunkcenkceshela yePVC, zombini imibhobho yeSchedule 40 kunye neSchedule 80 ziintlobo eziqhelekileyo zemibhobho yePVC yokunkcenkceshela. Ziphatha phantse ubungakanani obufanayo boxinzelelo, ngoko ke ukuba ukhetha iSchedule 40, akuyi kufuneka ukhathazeke malunga nokuphazamiseka rhoqo. Umbhobho weSchedule 80 unodonga olutyebileyo kwaye ngenxa yoko ulungile ngakumbi kwisakhiwo, ngoko unokufuna ukusebenzisa umbhobho weSchedule 80 ukuba wakha inkqubo engaphezulu komhlaba.

Nokuba ukhetha luphi uhlobo lombhobho wePVC, kubalulekile ukuba umbhobho uwubeke elangeni elincinci kangangoko kunokwenzeka. Nangona ezinye iintlobo zePVC zixhathisa ukukhanya kwelanga kunezinye, nawuphi na umbhobho wePVC obekwe elangeni ixesha elide unokuba buthathaka ngokukhawuleza. Kukho iindlela ezahlukeneyo zokukhusela elangeni kwinkqubo yakho yokunkcenkceshela. Iingubo ezi-3-4 zepeyinti yangaphandle yelatex zibonelela ngokhuseleko olufanelekileyo elangeni. Ungasebenzisa nokukhusela umbhobho wefoam. Iinkqubo zangaphantsi komhlaba azidingi khuselo elangeni. Okokugqibela, uxinzelelo lwamanzi aluyongxaki inkulu xa kufikwa kwimibhobho yamasebe. Uninzi lotshintsho loxinzelelo kwiinkqubo zokunkcenkceshela lwenzeka kumgca ophambili. Emva koko, uya kufuna kuphela umbhobho wePVC onomlinganiselo wePSI olingana noxinzelelo lwenkqubo.

ukubeka imibhobho

Indawo kunye nezixhobo
Ukuba ukhetha inkqubo engaphantsi komhlaba, qiniseka ukuba uyigquma imibhobho ubuncinane iisentimitha ezili-10 ubunzulu.Imibhobho yePVCzibuthathaka kwaye zinokuqhekeka okanye ziqhekeke lula xa zitshayiswa ngamandla yifosholo. Kwakhona, umbhobho wePVC ongangcwatywanga unzulu ngokwaneleyo ukuba ubusika bukwazi ukudada phezulu komhlaba. Kukwangumbono olungileyo ukubeka umbhobho wefoam kwizixhobo ezingaphezulu nangaphantsi komhlaba. Olu khuselo lukhusela imibhobho kwiinkqubo ezingaphezulu komhlaba elangeni kwaye lukhusela ekuqandeni ebusika.

Ukuba ukhetha ukusebenzisa umbhobho wePVC kwisebe lakho lokunkcenkceshela, qiniseka ukuba usebenzisa umbhobho onobukhulu obuyi-3/4″ ubuncinane. Isebe eliyi-1/2″ linokuvaleka lula. Ukuba ukhetha ukusebenzisa izixhobo zokufakela, uninzi lweentlobo zezixhobo zokufakela zePVC ziya kusebenza kakuhle. Izixhobo zokufakela ezine-primer/samente zingabamba ngokukhuselekileyo, kunye nezixhobo zokufakela ngentambo (isinyithi kunye nePVC). Ungasebenzisa nezixhobo zokufakela, ezitshixa endaweni yazo usebenzisa izitywino eziguquguqukayo kunye namazinyo. Ukuba usebenzisa izixhobo zokufakela ezifakelwayo, qiniseka ukuba ukhetha isixhobo sokufakela esinophawu olusemgangathweni ophezulu.

Ii-PEX Pipe kunye ne-Polyethylene Pipe Couplings
Umbhobho wePolyethylene kunye nombhobho wePEX nazo zizinto ezilungileyo kakhulu kumasebe okunkcenkceshela. Ezi zinto zisebenza kakuhle kwiinkqubo ezingaphantsi komhlaba; ukuguquguquka kwazo kuzenza zilungele ukusetyenziswa ecaleni komhlaba onamatye okanye amatye amakhulu. Umbhobho wePolyethylene kunye nombhobho wePEX nazo zisebenza kakuhle kwiindawo ezibandayo. Azidingi naluphi na ukhuselo olongezelelweyo ukuze zingangeni kubanda. Xa ukhetha ukusebenzisa enye okanye enye, khumbula ukuba umbhobho wePEX ngokuyintloko yinguqulelo enamandla kancinci yombhobho wepolyethylene. Nangona kunjalo, ixabiso eliphezulu lombhobho wePEX lenza ukuba ungasetyenziswa kwimisebenzi yokunkcenkceshela emikhulu. Imibhobho yePolyethylene ikwanokuqhekeka ngakumbi kunemibhobho yePVC. Kuya kufuneka ukhethe umbhobho onomlinganiselo wePSI ongama-20-40 ngaphezulu koxinzelelo olungashukumiyo. Ukuba inkqubo isetyenziswa kakhulu, kungcono ukusebenzisa inqanaba eliphezulu lePSI ukuqinisekisa ukuba akukho ziphazamiso zenzekayo.

Indawo kunye nezixhobo
Umbhobho wePolyethylene kunye nombhobho wePEX kufuneka zisetyenziswe kuphela kwiinkqubo ezingaphantsi komhlaba.Imibhobho yePVC,Kufuneka ugqume imibhobho yezi zinto ubuncinane ubunzulu obuziisentimitha ezili-10 ukuze uphephe ukufuthwa okanye ukonakala ebusika. Ukugquma imibhobho ye-polyethylene kunye ne-PEX kufuna amakhuba akhethekileyo, kodwa uninzi loomatshini bolu hlobo lunokwemba ukuya kuthi ga kwiisentimitha ezili-10 ubunzulu.

Umbhobho wePolyethylene kunye nombhobho wePEX zinokubotshelelwa kumgca oyintloko. Ukongeza, izixhobo zokufaka ezityhalwayo ziyafumaneka. IiSaddles ziya zisiba yindlela ethandwayo yokudibanisa i-polyethylene kunye ne-PEX tube kwii-sprinkler. Ukuba ukhetha ukusebenzisa i-saddle efuna ukubhobozwa, qiniseka ukuba uyicoca kakuhle imibhobho ngaphambi kokuba uyincamathisele kuyo nayiphi na into ukuze ususe iplastiki engaphezulu.
