Izixazululo zethu zaziwa kabanzi futhi zithenjwa ngabathengi futhi zizohlangabezana nezidingo eziqhubekayo ezithuthukayo zezezimali nezenhlalo Zomkhiqizi Oholayo we-China Plastic Material PVC (PVC-U, UPVC) PPR Union Ball Control Valve for Water Supply, Ukuze uthole amanye amaqiniso, kufanele thumela i-imeyili kithi. Sifuna abaphambili ithuba lokukuhlinzeka.
Izisombululo zethu zibonwa kabanzi futhi zithenjwa ngabathengi futhi zizohlangabezana nezidingo eziqhubekayo zokuthuthuka kwezezimali nezenhlaloI-China Ball Valve, I-Plastic Ball Valve, Ikhwalithi engcono kakhulu neyokuqala yezingxenye ezisele iyisici esibaluleke kakhulu kwezokuthutha. Singase sibambelele ekunikezeni izingxenye zangempela nezisezingeni elihle ngisho nenzuzo encane esiyitholile. UNkulunkulu uzosibusisa senze ibhizinisi lomusa kuze kube phakade.

PPR amapayipi

Uma kuqhathaniswa namapayipi ensimbi, amapayipi e-PPR anezinzuzo zokufakwa okulula, ukufakwa okungcono kwe-thermal, nokumelana nokugqwala. Iwumthombo wamanzi onempilo futhi ongayingeni imvelo futhi ingumkhiqizo wokuphakelwa kwamanzi ojwayelekile emakethe. Amapayipi e-PPR atholakala kakhulu ngemibala elandelayo, omhlophe, oMpunga, oluhlaza okotshani kanye nokhari, kungani kunomehluko udalwa ikakhulukazi ama-masterbatches anemibala ehlukene angezwe.

Ngokungeziwe ezicini zamapayipi epulasitiki ajwayelekile njengesisindo esilula, ukumelana nokugqwala, ukungancishisi, nempilo ende yenkonzo, amapayipi e-PP-R nawo anezici ezilandelayo eziyinhloko:

1 Akunabuthi futhi kuhlanzekile.
Ama-molecule wezinto ezingavuthiwe ze-PP-R ayizakhi ze-carbon ne-hydrogen kuphela, futhi azikho izinto eziyingozi nezinobuthi. Ihlanzekile futhi inokwethenjelwa. Ayisetshenziselwa kuphela amapayipi amanzi abandayo nashisayo, kodwa futhi nezinhlelo zamanzi okuphuza ahlanzekile.

2 Ukugcina ukushisa nokonga amandla.
I-conductivity eshisayo yepayipi ye-PP-R ingu-0.21w/mk, okuyi-1/200 kuphela yepayipi yensimbi.

3 Ukumelana nokushisa okungcono.
Iphoyinti lokuthambisa i-Vicat lepayipi le-PP-R ngu-131.5 ℃. Izinga lokushisa eliphakeme lokusebenza lingafinyelela ku-95 ℃, elingahlangabezana nezidingo zohlelo lwamanzi ashisayo endaweni yokwakhiwa kwamanzi kanye nekhodi yokukhipha amanzi.

4Impilo ende yesevisi.
Ngaphansi kwezimo zokushisa zokusebenza kwe-70 ℃ kanye nengcindezi yokusebenza (PN) ye-1.0MPa, impilo yesevisi yepayipi ye-PP-R ingafinyelela eminyakeni engaphezu kwengu-50 (inqobo nje uma impahla yepayipi kufanele ibe yi-S3.2 ne-S2.5 uchungechunge noma Okuningi); ngaphansi kwezinga lokushisa elivamile (20℃) Impilo yesevisi ingafinyelela eminyakeni engaphezu kweyi-100.

5 Ukufakwa okulula nokuxhumana okuthembekile.
I-PP-R inokusebenza okuhle kwe-welding. Amapayipi nokufakwa kungaxhunywa ngokuncibilika okushisayo kanye ne-electrofusion. Ukufakwa kulula futhi amalunga athembekile. Amandla okuhlangana makhulu kunamandla wepayipi ngokwayo.

6 Izinto zokwakha zingagaywa kabusha.
Imfucuza ye-PP-R iyahlanzwa, yephulwe, futhi igaywe kabusha ukuze isetshenziswe ekukhiqizeni amapayipi nokufakwa. Inani lezinto ezigaywe kabusha alidluli u-10% yenani eliphelele futhi alithinti ikhwalithi yomkhiqizo.

ukufakwa

Izixazululo zethu zaziwa kabanzi futhi zithenjwa ngabathengi futhi zizohlangabezana nezidingo eziqhubekayo ezithuthukayo zezezimali nezenhlalo Zomkhiqizi Oholayo we-China Plastic Material PVC (PVC-U, UPVC) PPR Union Ball Control Valve for Water Supply, Ukuze uthole amanye amaqiniso, kufanele thumela i-imeyili kithi. Sifuna abaphambili ithuba lokukuhlinzeka.
Umkhiqizi Ohamba phambili we-China Ball Valve, I-Plastic Ball Valve, Ikhwalithi engcono kakhulu neyokuqala yezingxenye ezisele iyisici esibaluleke kakhulu kwezokuthutha. Singase sibambelele ekunikezeni izingxenye zangempela nezisezingeni elihle ngisho nenzuzo encane esiyitholile. UNkulunkulu uzosibusisa senze ibhizinisi lomusa kuze kube phakade.
