Uma wakha uhlelo lwepayipi oluthembekile nolusebenzayo, ukukhetha izinsimbi ezifanele kubalulekile. Izinsimbi ze-PPR (polypropylene random copolymer) ziyisinqumo esithandwayo sezinhlelo eziningi zokufaka amapayipi kanye ne-HVAC ngenxa yokuqina kwazo, ukuphila isikhathi eside, kanye nokulula kokufakwa. Kulesi sihloko, sizohlola izinzuzo kanye nokusetshenziswa kwezinsimbi zepayipi ze-PPR, kanye nezinye izinto ezibalulekile okufanele uzicabangele lapho ukhetha futhi uzifaka.

Ukufakwa kwamapayipi e-PPR kuklanyelwe ngqoukuxhuma amapayipi e-PPR futhi avame ukusetshenziswa ezinhlelweni zokuphakelwa kwamanzi ashisayo nabandayo kanye nezicelo zokufudumeza nokupholisa. Lezi zesekeli zenziwe ngezinto ze-PPR ezisezingeni eliphezulu, ezaziwa ngokumelana nokushisa okuphezulu, amakhemikhali kanye nokugqwala. Lokhu kwenza ukufakwa kwamapayipi e-PPR kube kuhle kakhulu ezinhlotsheni ezahlukahlukene zezicelo, kufaka phakathi amaphrojekthi ezindawo zokuhlala, ezentengiselwano, kanye nezimboni.

Enye yezinzuzo eziyinhloko ze-Ukufakwa kwe-PPR kulula kakhulu ukukufaka.Ngokungafani nokufakwa kwensimbi kwendabuko, ukufakwa kwe-PPR kuxhuma ngokushesha nangokuphephile ngokuxhumeka okushisayo okuncibilikayo, okudala ijoyinti elingenamthungo nelingavuzi. Lokhu akugcini nje ngokusindisa isikhathi nezindleko zomsebenzi ngesikhathi sokufakwa, kodwa futhi kuqinisekisa ukuthembeka nokusebenza kwesikhathi eside kohlelo lwamapayipi. Ngaphezu kwalokho, ubuso obubushelelezi bangaphakathi bokufakwa kwe-PPR kunciphisa ukwehla kwengcindezi kanye nokuxokozela, kuthuthukise izici zokugeleza futhi kunciphise ukusetshenziswa kwamandla.

Enye inzuzo ye-PPR fittings yikhono lazo lokumelana nokunqwabelana kwesikali kanye nenhlabathi. Lokhu kubaluleke kakhulu ezinhlelweni zamanzi ashisayo, njengoba amadiphozithi amaminerali anganqwabelana ngokuhamba kwesikhathi futhi abangele ukuvaleka kanye nokugeleza okunciphile. I-PPR fittings isiza ekunciphiseni lezi zinkinga, ngaleyo ndlela inciphise izidingo zokulungisa futhi yandise impilo yesistimu yakho yamapayipi.

Ukufakwa kwe-PPR kuyatholakala ngezinhlobo ezahlukeneukwakheka nosayizi ukuze kuhlangatshezwane nezidingo ezahlukene zamapayipi. Kungakhathaliseki ukuthi ijoyinti elula eqondile noma ijoyinti eliyinkimbinkimbi noma i-elbow, amajoyinti e-PPR anikeza ukuguquguquka nokuguquguquka ekwakhiweni nasekufakweni. Lokhu kuvumela ukwakheka kwamapayipi okwenziwe ngokwezifiso nangokuphumelelayo okunamajoyinti amancane kanye nokufakwa, kunciphisa ingozi yokuvuza okungenzeka kanye nezindawo zokwehluleka.

Uma ukhetha izinto zokufaka ze-PPR zephrojekthi yakho, izici ezifana nezilinganiso zokucindezela kanye nokushisa, ukuhambisana kwamakhemikhali, kanye nezidingo ezithile zesicelo kumele zicatshangelwe. Kunconywa ukubonisana nonjiniyela ochwepheshe noma umhlinzeki ofanelekayo ukuqinisekisa ukuthi izesekeli ezikhethiwe ziyahlangabezana nezindinganiso zokusebenza kanye nokuphepha zokusetshenziswa okuhlosiwe.

Ukufakwa kahle kwe-PPR fittings kubalulekile ekuqineni nasekusebenzeni kahle kwesistimu yakho yamapayipi. Kunconywa ukulandela imihlahlandlela yokushisela yokuhlanganiswa komenzi kanye nemikhuba emihle kakhulu futhi usebenzise amathuluzi nemishini ekhethekile ukuze uqedele umsebenzi. Lokhu kuzosiza ekufezeni ijoyinti eqinile nehlala isikhathi eside futhi kunciphise ingozi yokuvuza noma ukwehluleka okungenzeka esikhathini esizayo.

Ngamafuphi, ukufakwa kwamapayipi e-PPR kuyingxenye ebalulekile yesistimu yamapayipi ethembekile nephumelelayo. Ukuqina kwawo, ukumelana nobukhulu nokugqwala, ukulula kokufakwa, kanye nokuguquguquka komklamo kuwenza abe ukukhetha kokuqala kokusetshenziswa kwamapayipi kanye ne-HVAC. Ngokukhetha ngokucophelela nokufaka ukufakwa kwamapayipi e-PPR, uhlelo lwamapayipi olusebenza kahle lungatholakala, okuholela ekusebenzeni okungenazinkinga kanye nokonga izindleko zesikhathi eside.
