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.

Izingcaphuno ezisheshayo nezimangalisayo, abeluleki abanolwazi ukukusiza ukhethe imikhiqizo efanele efanela zonke izidingo zakho, isikhathi esifushane sokukhiqiza, ukulawulwa kwekhwalithi enhle okunesibopho kanye nezinkampani ezihlukile zokukhokha nokuthumela izindaba zokulethwa okusheshayo eShayina I-Ifan PPR/Pex/PP Pipe and Fittings for Water Supply PPR 4 Way Cross Tee, Inhloso yethu kuzoba ukusiza abathengi baqonde imigomo yabo. Besilokhu senza imizamo emihle yokuthola lesi simo sokuwina wonke umuntu futhi siyakwamukela ngobuqotho ukuthi ubhalisele kithi nakanjani.
