Ukuze ukwazi ukwanelisa izidingo zekhasimende ngendlela efanele, yonke imisebenzi yethu yenziwa ngokuqinile ngokuhambisana nesiqubulo sethu esithi “Ikhwalithi Ephezulu, Umaki Wentengo Encintisanayo, Isevisi Esheshayo” Yokuthenga Okukhulu Komkhiqizi I-Wholesale PPR I-Brass Ball Valve engu-20mm-63mm PPR I-Double Union Ball Valve Stop Valves, Njengochwepheshe abazibophezele ekuvikeleni noma iyiphi inkinga yokushisa ukuze sixazulule le nkinga.
Ukuze sikwazi ukwanelisa izidingo zekhasimende ngendlela efanele, yonke imisebenzi yethu yenziwa ngokuvumelana nesiqubulo sethu esithi “Ikhwalithi Ephezulu, Umaka Wamanani Ancintisanayo, Isevisi Esheshayo” yei-valve yokumisa i-ppr, Njengoba siyizixazululo eziphezulu zefekthri yethu, uchungechunge lwethu lwezixazululo luhloliwe futhi lwasizuzela izitifiketi zeziphathimandla ezinolwazi. Ukuze uthole amapharamitha angeziwe nemininingwane yohlu lwezinto, qiniseka ukuthi uchofoza inkinobho ukuze uthole ulwazi olwengeziwe.

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 ngaphezulu); 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

Ukuze ukwazi ukwanelisa izidingo zekhasimende ngendlela efanele, yonke imisebenzi yethu yenziwa ngokuqinile ngokuhambisana nesiqubulo sethu esithi “Ikhwalithi Ephezulu, Umaki Wentengo Encintisanayo, Isevisi Esheshayo” Yokuthenga Okukhulu Komkhiqizi I-Wholesale PPR I-Brass Ball Valve engu-20mm-63mm PPR I-Double Union Ball Valve Stop Valves, Njengochwepheshe abazibophezele ekuvikeleni noma iyiphi inkinga yokushisa ukuze sixazulule le nkinga.
I-Super Purchasing ye-PPR I-Ball Valve I-Ball Valves I-Union Ball Valves kanye ne-PPR Double Union, Njengoba izisombululo eziphezulu zemboni yethu, uchungechunge lwethu lwezixazululo luhloliwe futhi lwasizuzela izitifiketi zeziphathimandla ezinolwazi. Ukuze uthole amapharamitha angeziwe nemininingwane yohlu lwezinto, qiniseka ukuthi uchofoza inkinobho ukuze uthole ulwazi olwengeziwe.
