Ukuze sihlangabezane nezidingo zamakhasimende, yonke imisebenzi yethu yenziwa ngokuhambisana nesiqubulo sethu esithi “Okuphezulu Okuhle Kakhulu, Intengo Yokuthengisa Enolaka, Isevisi Esheshayo”Ukufakwa Kwepayipi le-PPR laseShayina, I-PPR Ball Valve, Silangazelela ukubambisana nawe eduze nezinzuzo zethu zombili kanye nentuthuko ephezulu. Siqinisekisile ikhwalithi, uma amakhasimende enganelisekile ngekhwalithi yemikhiqizo, ungabuya zingakapheli izinsuku eziyi-7 enesimo sayo sokuqala.

Amapayipi e-PPR

Uma kuqhathaniswa namapayipi ensimbi, amapayipi e-PPR anezinzuzo zokufakwa okulula, ukuvikela ukushisa okungcono, kanye nokumelana nokugqwala. Kuyizinto zokunikeza amanzi ezinempilo futhi ezinobungani nemvelo futhi futhi kungumkhiqizo ojwayelekile wokunikeza amanzi emakethe. Amapayipi e-PPR atholakala kakhulu ngemibala elandelayo, emhlophe, empunga, eluhlaza kanye ne-curry, kungani kukhona lo mehluko ubangelwa kakhulu yimibala ehlukene ye-masterbatches engeziwe.

Ngaphezu kwezici zamapayipi epulasitiki ajwayelekile njengesisindo esincane, ukumelana nokugqwala, ukungakhuli, kanye nokuphila isikhathi eside, amapayipi e-PP-R nawo anezici ezilandelayo eziyinhloko:

1 Ayinabo ubuthi futhi ayihlanzekile.
Ama-molecule e-PP-R ayizinto zekhabhoni ne-hydrogen kuphela, futhi azikho izinto eziyingozi nezinobuthi. Ahlanzekile futhi athembekile. Akusetshenziswa nje kuphela emipayipini yamanzi abandayo nashisayo, kodwa futhi nasezinhlelweni zamanzi okuphuza ahlanzekile.

2 Ukulondolozwa kokushisa nokonga amandla.
Ukushisa kwepayipi le-PP-R kungu-0.21w/mk, okuyi-1/200 kuphela yepayipi lensimbi.

3 Ukumelana nokushisa okungcono.
Indawo yokuthambisa i-Vicat yepayipi le-PP-R ingu-131.5℃. Izinga lokushisa eliphezulu lokusebenza lingafinyelela ku-95℃, okungahlangabezana nezidingo zesistimu yamanzi ashisayo kukhodi yokuphakelwa kwamanzi neyokukhipha amanzi esakhiweni.

4Impilo yenkonzo ende.
Ngaphansi kwezimo zokushisa kokusebenza okungu-70℃ kanye nengcindezi yokusebenza (PN) engu-1.0MPa, impilo yokusebenza yepayipi le-PP-R ingafinyelela eminyakeni engaphezu kwengu-50 (uma nje izinto zepayipi kumele zibe uchungechunge lwe-S3.2 kanye ne-S2.5 noma ngaphezulu); ngaphansi kokushisa okuvamile (20℃) impilo yokusebenza ingafinyelela eminyakeni engaphezu kweyi-100.

5 Ukufakwa okulula nokuxhumeka okuthembekile.
I-PP-R isebenza kahle kakhulu ekushiseni. Amapayipi nezinto zokufaka zingaxhunywa ngokuncibilika okushisayo kanye nokuhlanganiswa kwe-electro. Ukufakwa kulula futhi amalunga athembekile. Amandla elungani makhulu kunamandla epayipi uqobo.

Izinto ezi-6 zingaphinde zisetshenziswe.
Imfucuza ye-PP-R iyahlanzwa, iphulwe, futhi isetshenziswe kabusha ukuze isetshenziswe ekukhiqizweni kwamapayipi kanye nokufakwa. Inani lezinto ezisetshenziswe kabusha alidluli u-10% wenani eliphelele futhi alithinti ikhwalithi yomkhiqizo.

ukufakwa

Ukuze sihlangabezane nezidingo zamakhasimende, yonke imisebenzi yethu yenziwa ngokuhambisana nesiqubulo sethu esithi “Intengo Ephakeme Engcono Kakhulu, Ukuthengisa Okunolaka, Isevisi Esheshayo” sePhayiphi Yepulasitiki yaseShayina ye-PPR (PP) Esezingeni Eliphezulu kanye Nokufakwa Ngengcindezi ye-Pn12.5/Pn20/Pn16/Pn25 Yamanzi Ashisayo, “Shintsha ngokungcono kakhulu!” yisiqubulo sethu, okusho ukuthi “Imbulunga enkulu iphambi kwethu, ngakho-ke masijabulele!” Shintsha kube ngcono! Usulungele ngokuphelele?
Ukufakwa Kwepayipi Le-PPR LaseShayina Elisezingeni Eliphezulu, I-PPR Ball Valve, Silangazelela ukubambisana nawe eduze ukuze sizuze kanye nentuthuko yethu ephezulu. Siqinisekisile ikhwalithi, uma amakhasimende enganelisekile ngekhwalithi yemikhiqizo, ungabuya zingakapheli izinsuku eziyi-7 ngesimo sayo sokuqala.
