Iiprojekthi zokunkcenkceshela ngumsebenzi odla ixesha onokukhawuleza ubize kakhulu.Indlela enkulu yokugcina imali kwiprojekthi yokunkcenkceshela kukusebenzisa umbhobho wePVC kumbhobho wesebe, okanye umbhobho phakathi kwevalve kumbhobho oyintloko wamanzi kunye ne-sprinkler.Ngelixa umbhobho wePVC usebenza kakuhle njengento enqamlezileyo, uhlobo lombhobho wePVC olufunekayo luyahluka ukusuka kumsebenzi ukuya kumsebenzi.Xa ukhetha ukuba yeyiphi imibhobho oza kuyisebenzisa emsebenzini wakho, kubalulekile ukuba uqikelele ukuba uthathela ingqalelo izinto zangaphandle ezifana noxinzelelo lwamanzi nokukhanya kwelanga.Ukukhetha uhlobo olungalunganga kunokukhokelela kuninzi olongezelelweyo, ukugcinwa okungadingekile.Isithuba seblogi sale veki sigubungela iintlobo eziqhelekileyo zemibhobho yokunkcenkceshela ye-PVC.Zilungiselele ukonga ixesha, amanzi kunye nemali!

IShedyuli 40 kunye neShedyuli 80 PVC Umbhobho PVC Pipe
Xa ukhetha imibhobho yokunkcenkceshela ye-PVC, zombini iipayipi zeShedyuli 40 kunye neShedyuli 80 ziintlobo eziqhelekileyo zombhobho wePVC wokunkcenkceshela.Baphatha phantse umlinganiselo ofanayo woxinzelelo, ke ukuba ukhetha iShedyuli yama-40, awuzukukhathazeka malunga nokuphazamiseka rhoqo.Umbhobho weShedyuli 80 uneendonga ezingqindilili kwaye ke ngoko uvakala ngakumbi ngokwesakhiwo, ngoko unokufuna ukusebenzisa umbhobho weShedyuli 80 ukuba wakha inkqubo engaphezulu komhlaba.

Kungakhathaliseki ukuba uluphi uhlobo lwepayipi yePVC oyikhethayo, kubalulekile ukuveza umbhobho ekukhanyeni kwelanga okuncinci kunokwenzeka.Ngelixa ezinye iintlobo zePVC zixhathisa ngakumbi ekukhanyeni kwelanga kunezinye, nawuphi na umbhobho wePVC ovezwe elangeni ixesha elide unokonakala ngokukhawuleza.Kukho iindlela ezininzi zokukhusela ilanga kwinkqubo yakho yokunkcenkceshela.Iingubo ezi-3-4 zepeyinti ye-latex yangaphandle zibonelela ngokhuseleko olwaneleyo elangeni.Ungasebenzisa kwakhona ukugquma kombhobho we-foam.Iinkqubo zangaphantsi komhlaba azifuni ukukhuselwa elangeni.Ekugqibeleni, uxinzelelo lwamanzi alungomba omkhulu xa kuziwa kwimibhobho yesebe.Uninzi lweenguqu zoxinzelelo kwiinkqubo zokunkcenkceshela zenzeka kumgca oyintloko.Emva koko, uya kufuna kuphela umbhobho wePVC ngokulinganisa kwePSI elingana noxinzelelo lwenkqubo.

ukufakwa kombhobho

Ukubekwa kunye neZincedisi
Ukuba ukhetha inkqubo yangaphantsi komhlaba, qiniseka ukuba ungcwaba imibhobho ubuncinane ubunzulu obuyi-intshi ezili-10.Imibhobho yePVCzi-brittle kwaye ziyakwazi ukuqhekeka okanye ukuphuka ngokulula kunye neempembelelo ezinamandla ezivela kwifosholo.Kwakhona, umbhobho wePVC ongangcwatywanga unzulu ngokwaneleyo ukuba ubusika bukwazi ukudada phezu komhlaba.Ikwangumbono olungileyo ukubeka ukugquma kombhobho wogwebu kuzo zombini iinkqubo ezingaphezulu nangaphantsi komhlaba.Oku kugquma kukukhusela imibhobho ekwinkqubo engaphezulu komhlaba ekukhanyeni kwelanga kwaye ikhusela kwiqhwa ebusika.

Ukuba ukhetha ukusebenzisa umbhobho wePVC kwisebe lakho lokunkcenkceshela, qiniseka ukuba usebenzisa umbhobho ubuncinane obuyi-3/4″ ubukhulu.I-1/2" yesebe inokuvala ngokulula.Ukuba ukhetha ukusebenzisa izifakelo, uninzi lweentlobo eziqhelekileyo zofakelo lwePVC ziya kusebenza kakuhle.Amalungu e-socket ane-primer / i-samente angakwazi ukubamba ngokukhuselekileyo, njengoko kunokuthi kufakwe i-threaded joints (intsimbi kunye ne-PVC).Unokusebenzisa izixhobo zokutyhala, ezitshixayo usebenzisa izitywina eziguquguqukayo kunye namazinyo.Ukuba usebenzisa i-push-fittings, qiniseka ukuba ukhethe ukufakwa kunye nesitywina somgangatho ophezulu.

Umbhobho wePolyethylene kunye ne-PEX Umbhobho we-PEX Couplings
Umbhobho wePolyethylene kunye nombhobho wePEX nazo zizixhobo ezigqwesileyo kumasebe okunkcenkceshela.Ezi zixhobo zisebenza kakuhle kwiinkqubo eziphantsi komhlaba;ukuguquguquka kwabo kubenza balungele ukusetyenziswa ecaleni komhlaba onamatye okanye amatye amakhulu.Umbhobho wePolyethylene kunye nombhobho wePEX nawo usebenza kakuhle kwiindawo ezibandayo.Abafuni nakuphi na ukugquma okongeziweyo ukuze bathintele ingqele.Xa ukhetha ukusebenzisa enye okanye enye, khumbula ukuba umbhobho we-PEX ngowona uguqulelo olunamandla kancinane lombhobho we-polyethylene.Nangona kunjalo, ixabiso eliphezulu lombhobho wePEX lenza ukuba ungasebenziseki kwimisebenzi emikhulu yokunkcenkceshela.Imibhobho yePolyethylene nayo ithande ukuqhawuka kunemibhobho yePVC.Emva koko kuya kufuneka ukhethe umbhobho nge-PSI yokulinganisa i-20-40 ephezulu kunoxinzelelo lwe-static.Ukuba inkqubo isetyenziswa kakhulu, kungcono ukusebenzisa inqanaba eliphezulu le-PSI ukuqinisekisa ukuba akukho ziphazamiso ezenzekayo.

Ukubekwa kunye neZincedisi
Umbhobho we-polyethylene kunye nombhobho we-PEX kufuneka usetyenziswe kuphela kwiinkqubo eziphantsi komhlaba.NjengoImibhobho yePVC,kufuneka ungcwabe imibhobho yezi zixhobo ubuncinane i-intshi ezili-10 ubunzulu ukuphepha ukuhlatywa kunye nomonakalo ebusika.Ukungcwaba i-polyethylene kunye nemibhobho ye-PEX kufuna amakhuba akhethekileyo, kodwa oomatshini abaninzi bolu hlobo banokugrumba ukuya kutsho kwi-intshi ezili-10 ubunzulu.

Umbhobho we-polyethylene kunye nombhobho we-PEX unokunyanzeliswa kumgca oyintloko.Ukongeza, i-push-fittings iyafumaneka.Iisali ziya ziba yindlela ethandwa kakhulu yokudibanisa i-polyethylene kunye ne-PEX ityhubhu kwizitshizi.Ukuba ukhetha ukusebenzisa isali efuna ukugrunjwa, qiniseka ukuba ucoce imibhobho ngokucokisekileyo ngaphambi kokuba unamathele kuyo nayiphi na into ukususa iplastiki engaphezulu.
