Imibala ye-Iron Pipe kunye neeMfuno eziKhethekileyo zeeMarike

Umbala weimibhobho yentsimbiidla ngokunxulumene nokusetyenziswa kwabo, unyango lokuchasana nomhlwa okanye imigangatho yoshishino. Amazwe ahlukeneyo kunye namashishini anokuba neemfuneko ezithile zemibala ukuqinisekisa ukhuseleko, ukuxhathisa ukubola okanye ukuchongwa ngokulula. Olu lulandelayo luhlelo oluneenkcukacha:

1. Intsingiselo ngokubanzi yombala we-DINSEN SML Umbhobho

·Mnyama/mnyama ngwevu/Intsimbi yokuqala okanye i-asphalt/anti-corrosion coating Imisele yamanzi amdaka, ilindle, imibhobho kamasipala

·Bomvu/Imibhobho yomlilo, ukumelana nobushushu obuphezulu okanye iimpawu ezikhethekileyo/Inkqubo yomlilo, ukunikezelwa kwamanzi oxinzelelo oluphezulu

·Luhlaza/Imibhobho yamanzi okusela, iingubo zokusingqongileyo (ezifana ne-epoxy resin)/Amanzi etephu, unikezelo lwamanzi ebakala lokutya

·Luhlaza/Amanzi emizi-mveliso, umoya ocinezelweyo/Umzi-mveliso, inkqubo yomoya ecinezelweyo

·Lubhelu/Imibhobho yerhasi (intsimbi encinci, ubukhulu becala imibhobho yentsimbi)/Ukuhanjiswa kwerhasi (ezinye iindawo zisasebenzisa intsimbi etyhidiweyo)

·Isilivere/Unyango lokulwa nomhlwa/Indawo engaphandle, efumileyo, iimfuno zokuxhathisa umhlwa

2. Iimfuno ezikhethekileyo zemibala yemibhobho yentsimbi kwiimarike zasekhaya nezangaphandle 

(1) Imarike yaseTshayina (umgangatho we-GB)

I-Drainage Cast Iron Pipes: idla ngokuba mnyama (asphalt anti-corrosion) okanye intsimbi yokuqala engwevu, iqatywe i-epoxy resin (eluhlaza).

Ubonelelo lwaManzi Umbhobho wentsimbi:Umbhobho wentsimbi eqhelekileyo: emnyama okanye ebomvu (ukukhusela umlilo).

I-Ductile Iron Pipe (DN80-DN2600): udonga lwangaphandle olufafazwe nge-zinc + asphalt (emnyama), umgca wangaphakathi kunye nesamente okanye i-epoxy resin (grey / eluhlaza).

Umbhobho woKhuseleko loMlilo: ukugquma obomvu, ngokuhambelana nenkcazo yokukhusela umlilo we-GB 50261-2017.

Umbhobho weGesi: umthubi (kodwa imibhobho yerhasi yanamhlanje ininzi yenziwe nge-PE okanye imibhobho yentsimbi, kwaye intsimbi ekhandiweyo ayifane isetyenziswe).

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

I-AWWA C151 (umbhobho wentsimbi ophumayo):
Udonga lwangaphandle: ngokuqhelekileyo kumnyama (i-asphalt yokugqoka) okanye isilivere (i-galvanized).
Umgca wangaphakathi: udaka lwesamente (grey) okanye i-epoxy resin (eluhlaza / eluhlaza okwesibhakabhaka).

Umbhobho wokuKhusela uMlilo (umgangatho we-NFPA): uphawu olubomvu, ezinye zifuna amagama athi "INKONZO YOMLILO" ukuba iprintwe.

Umbhobho wamanzi okusela (i-NSF / ANSI 61 isatifikethi): i-lining yangaphakathi kufuneka ihlangabezane nemigangatho yococeko, akukho mfuneko efunekayo kumbala wodonga lwangaphandle, kodwa i-logo eluhlaza okanye eluhlaza okwesibhakabhaka isetyenziswa rhoqo.

(3) Imarike yaseYurophu (EN umgangatho)

EN 545/EN 598 (umbhobho wentsimbi ophumayo):

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

I-Inner Lining: i-cement mortar okanye i-epoxy resin, akukho migaqo yombala engqongqo, kodwa kufuneka ihambelane nemigangatho yamanzi okusela (njenge-KTW certification).

Umbhobho womlilo: obomvu (amanye amazwe afuna ushicilelo "FEUER" okanye "FIRE").

Umbhobho woShishino: unokuba luhlaza okwesibhakabhaka (umoya ocinezelweyo) okanye umthubi (irhasi, kodwa imibhobho yentsimbi iye yatshintshwa ngokuthe ngcembe).

(4) Imarike yaseJapan (i-JIS eqhelekileyo)

I-JIS G5526 (umbhobho we-iron ductile): Udonga lwangaphandle luhlala lumnyama (i-asphalt) okanye i-galvanized (isilivere), kwaye i-internal lining yi-samente okanye i-resin.

Umbhobho womlilo: umzobo obomvu, ezinye zifuna ukuprinta "ukulwa nomlilo".

Umbhobho wamanzi okusela: i-lining eluhlaza okanye eluhlaza okwesibhakabhaka, ngokuhambelana nomgangatho we-JHPA.

3. Impembelelo yombala weengubo ezikhethekileyo ezichasene ne-corrosion

I-epoxy resin coating: ngokuqhelekileyo eluhlaza okanye eluhlaza okwesibhakabhaka, esetyenziselwa iimfuno eziphezulu zokuchasana nokubola (njengamanzi olwandle, ishishini lemichiza).
I-polyurethane yokwambathisa: inokuba luhlaza, imnyama okanye ityheli, kunye nokumelana nemozulu enamandla.
I-Zinc + yokugqoka i-asphalt: udonga lwangaphandle olumnyama, olufanelekileyo kwimibhobho engcwatywe.

4. Isishwankathelo: Indlela yokukhetha umbala wemibhobho yentsimbi?

Khetha ngokusetyenziswa:
Ugutyulo lwamanzi amdaka → mnyama/ngwevu
Amanzi okusela → eluhlaza/blue
Ukucima umlilo → obomvu
Ishishini → ngokuchongwa okuphakathi (okufana nerhasi emthubi, umoya oxiniweyo oluhlaza)

Khetha ngokomgangatho:
I-China (GB) → emnyama (umsele), obomvu (ukucima umlilo), eluhlaza (amanzi okusela)
IYurophu kunye ne-United States (AWWA/EN) → emnyama (i-anti-corrosion yangaphandle), eluhlaza / eluhlaza okwesibhakabhaka (i-lining)
IJapan (JIS) → emnyama (udonga lwangaphandle), ebomvu (ukucima umlilo)
