Imibala ye-Cast Iron Pipe kanye Nezimfuneko Ezikhethekile Zezimakethe

Umbala weamapayipi ensimbingokuvamile kuhlobene nokusetshenziswa kwazo, ukwelashwa okunqanda ukugqwala noma amazinga emboni. Amazwe ahlukene nezimboni zingaba nezidingo ezithile zemibala ukuze kuqinisekiswe ukuphepha, ukumelana nokugqwala noma ukuhlonza kalula. Okulandelayo ukuhlukaniswa okuningiliziwe:

1. Incazelo evamile yombala wepayipi le-DINSEN SML

·Okumnyama/okumpunga okumnyama/Insimbi yokuqala eyinsimbi noma i-asphalt/anti-corrosion coating Imisele, indle, amapayipi kamasipala

·Okubomvu/Amapayipi omlilo, ukumelana nokushisa okuphezulu noma izimpawu ezikhethekile/Uhlelo lomlilo, ukunikezwa kwamanzi anengcindezi ephezulu

·Okuhlaza/Amapayipi amanzi okuphuza, izinto zokumboza ezinobungani bemvelo (njenge-epoxy resin)/Amanzi kampompi, amanzi ebanga lokudla

·Okuluhlaza okwesibhakabhaka/Amanzi ezimboni, umoya ocindezelweyo/Imboni, isistimu yomoya ecindezelwe

·Okuphuzi/Amapayipi egesi (insimbi engasansimbi, ikakhulukazi amapayipi ensimbi)/Ukudluliswa kwegesi (ezinye izindawo zisasebenzisa insimbi ekhonjiwe)

·Isiliva/Ukwelashwa kwe-galvanized anti-rust/Indawo engaphandle, enomswakama, izidingo eziphakeme zokumelana nokugqwala

2. Izidingo ezikhethekile zemibala yamapayipi ensimbi ezimakethe zasekhaya nezangaphandle 

(1) Imakethe yaseShayina (i-GB ejwayelekile)

I-Drainage Cast Iron Pipes: ngokuvamile imnyama (asphalt anti-corrosion) noma i-iron grey yoqobo, embozwe ingxenye nge-epoxy resin (eluhlaza).

Ipayipi Lensimbi Lokufaka Amanzi:Ipayipi lensimbi elivamile: elimnyama noma elibomvu (lokuvikela umlilo).

I-Ductile Iron Pipe (DN80-DN2600): udonga lwangaphandle olufafazwe nge-zinc + asphalt (emnyama), ulwelwesi lwangaphakathi olunosimende noma i-epoxy resin (grey/green).

Ipayipi Lokuvikela Umlilo: ukumbozwa okubomvu, ngokuhambisana nencazelo yokuvikela umlilo ye-GB 50261-2017.

Ipayipi Legesi: ophuzi (kodwa amapayipi egesi esimanje ngokuvamile enziwe ngamapayipi e-PE noma ensimbi, futhi insimbi ekhonjiwe ayisetshenziswanga).

(2) Imakethe yase-US (AWWA/ANSI Standard)

I-AWWA C151 (ipayipi le-iron ductile):
Udonga lwangaphandle: ngokuvamile olumnyama (i-asphalt enamathela) noma isiliva (i-galvanized).
Ulayini lwangaphakathi: udaka lukasimende (ompunga) noma i-epoxy resin (eluhlaza/luhlaza okwesibhakabhaka).

Ipayipi Lokuvikela Umlilo (okujwayelekile kwe-NFPA): ilogo ebomvu, eminye idinga amagama athi “FIRE SERVICE” ukuze iphrintwe.

Ipayipi Lamanzi Okuphuza (isitifiketi se-NSF/ANSI 61): ulwelwesi lwangaphakathi kufanele luhlangabezane nezindinganiso zokuhlanzeka, asikho isidingo esiyisibopho sombala ongaphandle wodonga, kodwa ilogo eluhlaza noma eluhlaza okwesibhakabhaka ivame ukusetshenziswa.

(3) Imakethe yaseYurophu (EN standard)

I-EN 545/EN 598 (ipayipi le-iron ductile):

I-Anticorrosion yangaphandle: i-zinc + asphalt (emnyama) noma i-polyurethane (eluhlaza).

I-Inner Lining: udaka lukasimende noma i-epoxy resin, ayikho imithetho eqinile yombala, kodwa kufanele ihambisane nezindinganiso zamanzi okuphuza (njengesitifiketi se-KTW).

Ipayipi Lomlilo: libomvu (amanye amazwe adinga ukuphrinta "FEUER" noma "FIRE").

Ipayipi Lemboni: lingaba luhlaza okwesibhakabhaka (umoya ocindezelwe) noma ophuzi (igesi, kodwa amapayipi ensimbi ashintshiwe kancane kancane).

(4) Imakethe yaseJapan (i-JIS ejwayelekile)

I-JIS G5526 (ipayipi le-iron ductile): Udonga lwangaphandle luvamise ukuba mnyama (itiyela) noma uthayela (isiliva), futhi ulwelwesi lwangaphakathi luwusimende noma inhlaka.

Ipayipi lomlilo: umdwebo obomvu, ezinye zidinga ukuphrinta "ukulwa nomlilo".

Ipayipi lamanzi okuphuza: umugqa oluhlaza noma oluhlaza okwesibhakabhaka, ngokuhambisana nezinga le-JHPA.

3. Ithonya lombala wezingubo ezikhethekile zokulwa nokugqwala

I-epoxy resin coating: ngokuvamile eluhlaza noma eluhlaza okwesibhakabhaka, esetshenziselwa izidingo eziphezulu zokulwa nokugqwala (njengamanzi olwandle, imboni yamakhemikhali).
I-polyurethane enamathela: ingase ibe luhlaza, emnyama noma ephuzi, enokumelana okuqinile kwesimo sezulu.
I-Zinc + asphalt yokugqoka: udonga lwangaphandle olumnyama, olufanele amapayipi angcwatshwe.

4. Isifinyezo: Ungakhetha kanjani umbala wamapayipi ensimbi?

Khetha ngokusebenzisa:
Indle/indle → emnyama/mpunga
Amanzi okuphuza → aluhlaza/aluhlaza okwesibhakabhaka
Ukucima umlilo → okubomvu
Imboni → ngokuhlonza okumaphakathi (okufana negesi ephuzi, umoya ocindezelwe okwesibhakabhaka)

Khetha ngokwezinga:
I-China (GB) → emnyama (i-drainage), ebomvu (yokucima umlilo), eluhlaza (amanzi okuphuza)
I-Europe ne-United States (AWWA/EN) → emnyama (i-anti-corrosion yangaphandle), eluhlaza/oluhlaza okwesibhakabhaka (umugqa)
I-Japan (JIS) → emnyama (udonga olungaphandle), olubomvu (ukucisha umlilo)

Uma namanje ungazi ukuthi ungakhetha kanjani, sicela uxhumane no-DINSEN
