Xa usakha isixokelelwano sombhobho othembekileyo nesisebenzayo, ukukhetha izixhobo ezifanelekileyo kubalulekile. Ukufakwa kwePPR (i-polypropylene random copolymer) lukhetho oludumileyo kwimibhobho emininzi kunye nezicelo ze-HVAC ngenxa yokuqina kwazo, ubomi obude, kunye nokulula kofakelo. Kule nqaku, siza kuhlolisisa izibonelelo kunye nokusetyenziswa kwe-PPR yokufakelwa kombhobho, kunye neengqwalasela ezibalulekileyo xa ukhetha kwaye uyifaka.

Izixhobo zombhobho wePPR zenzelwe ngokukodwaukudibanisa imibhobho yePPR kwaye isetyenziswa ngokuqhelekileyo kwiinkqubo zokubonelela ngamanzi ashushu nabandayo kunye nezicelo zokufudumeza kunye nokupholisa. Ezi zixhobo zenziwe kwizinto eziphezulu zePPR, ezaziwa ngokuchasana nokushisa okuphezulu, iikhemikhali kunye nokubola. Oku kwenza ukuba ukufakwa kombhobho wePPR kube kuhle kwiinkqubo ezahlukeneyo, kubandakanywa iiprojekthi zokuhlala, zorhwebo, kunye nezoshishino.

Enye yeenzuzo eziphambili zeIzixhobo zePPR kukulula kwazo ukufakela.Ngokungafaniyo nezixhobo zetsimbi zendabuko, izixhobo zePPR zidibanisa ngokukhawuleza kwaye zikhuselekile kunye noqhagamshelo olushushu oluyinyibilikayo, lwenza udibaniso olungenamthungo kunye nobungqina bokuvuza. Oku akugcini nje ukugcina ixesha kunye neendleko zabasebenzi ngexesha lofakelo, kodwa kwakhona kuqinisekisa ukuthembeka kwexesha elide kunye nokusebenza kwenkqubo yokubhobhoza. Ukongeza, umgangatho wangaphakathi ogudileyo wokufakelwa kwePPR unciphisa ukuhla koxinzelelo kunye nesiphithiphithi, uphucula iimpawu zokuhamba kunye nokunciphisa ukusetyenziswa kwamandla.

Olunye uncedo lofakelo lwePPR kukukwazi kwabo ukumelana nokwakhiwa kwesikali kunye nentlenga. Oku kubaluleke kakhulu kwiinkqubo zokubonelela ngamanzi ashushu, njengoko iidiphozithi zamaminerali zingakha ngokuhamba kwexesha kwaye zibangele ukuvala kunye nokunciphisa ukuhamba. Ufakelo lwePPR lunceda ukunciphisa le miba, ngaloo ndlela kuncitshiswa iimfuno zogcino kunye nokwandisa ubomi benkqubo yakho yemibhobho.

Izixhobo zePPR zifumaneka kwiindidi ezahlukeneyoyolungelelwaniso kunye nobukhulu ukuhlangabezana neemfuno ezahlukeneyo zemibhobho yamanzi. Ingaba i-straight-through joint okanye i-tee eyinkimbinkimbi okanye i-elbow joint, ii-PPR ezidibeneyo zibonelela ngezinto ezininzi kunye nokuguquguquka kuyilo kunye nofakelo. Oku kuvumela ukucwangciswa kwemibhobho yesiko kunye nokusebenza kakuhle kunye namalungu amancinci kunye nokufakelwa, ukunciphisa umngcipheko wokuvuza okunokwenzeka kunye namanqaku angaphumeleli.

Xa ukhetha ukufakwa kwePPR kwiprojekthi yakho, izinto ezinje ngoxinzelelo kunye nomgangatho wobushushu, ukuhambelana kweekhemikhali, kunye neemfuno ezithile zesicelo kufuneka ziqwalaselwe. Kucetyiswa ukuba udibane nenjineli yobuchwephesha okanye umboneleli oqeqeshiweyo ukuqinisekisa ukuba izixhobo ezikhethiweyo ziyahlangabezana nemigangatho yokusebenza kunye nokhuseleko kusetyenziso olucetywayo.

Ufakelo olufanelekileyo lofakelo lwePPR lubalulekile kwimfezeko iyonke kunye nokusebenza kwenkqubo yakho yemibhobho. Kucetyiswa ukuba ulandele izikhokelo zokudityaniswa komenzi we-welding kunye nezenzo ezilungileyo kunye nokusebenzisa izixhobo ezikhethekileyo kunye nezixhobo ukugqiba umsebenzi. Oku kuya kunceda ukufezekisa umdibaniso owomeleleyo kunye nohlala ixesha elide kunye nokunciphisa umngcipheko wokuvuza okunokwenzeka kwexesha elizayo okanye ukusilela.

Isishwankathelo, izixhobo zombhobho wePPR ziyinxalenye ebalulekileyo yenkqubo yokubhobhoza ethembekileyo nesebenzayo. Ukuqina kwabo, ukuchasana nesikali kunye nokugqwala, ukulula kofakelo, kunye nokuguquguquka koyilo kubenza babe lukhetho lokuqala lwe-plumbing kunye nezicelo ze-HVAC. Ngokukhetha ngokucokisekileyo kunye nokufakela izixhobo zombhobho wePPR, inkqubo yepayipi ephezulu yokusebenza inokufezekiswa, okukhokelela ekusebenzeni okungenangxaki kunye nokugcinwa kweendleko zexesha elide.
