Umbala weamapayipi ensimbi acishiwengokuvamile kuhlobene nokusetshenziswa kwazo, ukwelashwa kokulwa nokugqwala noma amazinga emboni. Amazwe ahlukene kanye nezimboni zingaba nezidingo ezithile zemibala ukuqinisekisa ukuphepha, ukumelana nokugqwala noma ukuhlonza okulula. Okulandelayo ukuhlukaniswa okuningiliziwe:
1. Incazelo ejwayelekile yombala wepayipi le-DINSEN SML
·Okumnyama/okumpunga okumnyama/Insimbi yokuqala noma i-asphalt/ungqimba olulwa nokugqwala Amanzi okuhambisa amanzi, indle, amapayipi kamasipala
·Okubomvu/Amapayipi omlilo, ukumelana nokushisa okuphezulu noma izimpawu ezikhethekile/Uhlelo lomlilo, ukuhlinzekwa kwamanzi ngomfutho ophezulu
·Okuluhlaza okotshani/Amapayipi amanzi okuphuza, izembozo ezinobungani nemvelo (njenge-epoxy resin)/Amanzi ompompi, ukuphakelwa kwamanzi okudla okuphansi
·Okuluhlaza okwesibhakabhaka/Amanzi ezimboni, umoya ocindezelwe/Ifektri, uhlelo lomoya olucindezelwe
·Ophuzi/Amapayipi egesi (insimbi encane ephonswe phansi, ikakhulukazi amapayipi ensimbi)/Ukudluliswa kwegesi (ezinye izindawo zisasebenzisa insimbi ephonswe ngensimbi)
·Isiliva/Ukwelashwa okulwa nokugqwala okugayiwe/Indawo engaphandle, enomswakama, izidingo eziphezulu zokumelana nokugqwala
2. Izidingo ezikhethekile zemibala yamapayipi ensimbi ecijile ezimakethe zasekhaya nezangaphandle
(1) Imakethe yaseShayina (izinga le-GB)
Amapayipi Ensimbi Ehlanganisiwe: ngokuvamile amnyama (alwa nokugqwala nge-asphalt) noma ampunga wensimbi wokuqala, ambozwe kancane nge-epoxy resin (eluhlaza okotshani).
Ipayipi Lensimbi Ehlanganisiwe Yokuphakelwa Kwamanzi:Ipayipi lensimbi elijwayelekile: elimnyama noma elibomvu (lokuvikela umlilo).
Ipayipi Lensimbi Elihlanganisiwe (DN80-DN2600): udonga lwangaphandle olufuthwe nge-zinc + asphalt (emnyama), ulwelwesi lwangaphakathi olufakwe usimende noma i-epoxy resin (empunga/eluhlaza).
Ipayipi Lokuvikela Umlilo: ungqimba olubomvu, oluhambisana nencazelo yokuvikela umlilo ye-GB 50261-2017.
Ipayipi Legesi: eliphuzi (kodwa amapayipi egesi esimanje enziwe kakhulu ngamapayipi e-PE noma ensimbi, futhi insimbi ephonswe ayisetshenziswa kakhulu).
(2) Imakethe yase-US (i-AWWA/ANSI Standard)
I-AWWA C151 (ipayipi lensimbi elithambile):
Udonga lwangaphandle: ngokuvamile olumnyama (ungqimba lwe-asphalt) noma isiliva (olufakwe i-galvanized).
Ulwelwesi lwangaphakathi: udoti wesamente (ompunga) noma i-epoxy resin (oluhlaza/oluhlaza okwesibhakabhaka).
Ipayipi Lokuvikela Umlilo (i-NFPA standard): uphawu olubomvu, amanye adinga amagama athi “FIRE SERVICE” ukuze aphrintwe.
Ipayipi Lamanzi Okuphuza (isitifiketi se-NSF/ANSI 61): ulwelwesi lwangaphakathi kumele luhlangabezane nezindinganiso zokuhlanzeka, akukho mfuneko ephoqelekile yombala wodonga lwangaphandle, kodwa ilogo eluhlaza noma eluhlaza okwesibhakabhaka ivame ukusetshenziswa.
(3) Imakethe yaseYurophu (EN standard)
I-EN 545/EN 598 (ipayipi le-iron ductile):
Ukuvimbela ukugqwala kwangaphandle: i-zinc + i-asphalt (emnyama) noma i-polyurethane (eluhlaza okotshani).
I-Inner Lining: udoti wesamente noma i-epoxy resin, akukho mithetho eqinile yombala, kodwa kumele ihambisane nezindinganiso zamanzi okuphuza (njengesitifiketi se-KTW).
Ipayipi Lomlilo: elibomvu (amanye amazwe adinga ukuphrinta okuthi “FEUER” noma “FIRE”).
Ipayipi Lezimboni: lingaba luhlaza okwesibhakabhaka (umoya ocindezelwe) noma ophuzi (igesi, kodwa amapayipi ensimbi ancibilikisiwe ashintshwe kancane kancane).
(4) Imakethe yaseJapan (i-JIS ejwayelekile)
I-JIS G5526 (ipayipi lensimbi elithambile): Udonga lwangaphandle luvame ukuba mnyama (i-asphalt) noma i-galvanized (isiliva), kanti ulwelwesi lwangaphakathi luyi-samente noma i-resin.
Ipayipi lomlilo: upende obomvu, eminye idinga ukunyatheliswa "kokulwa nomlilo".
Ipayipi lamanzi okuphuza: ulwelwesi oluluhlaza noma oluluhlaza okwesibhakabhaka, oluhambisana nezindinganiso ze-JHPA.
3. Ithonya lombala wezingubo ezikhethekile zokulwa nokugqwala
Ukugqoka i-resin ye-epoxy: ngokuvamile kuluhlaza okwesibhakabhaka noma okuluhlaza okwesibhakabhaka, okusetshenziselwa izidingo eziphezulu zokulwa nokugqwala (njengamanzi olwandle, imboni yamakhemikhali).
Ukugqoka kwe-polyurethane: kungaba luhlaza okotshani, okumnyama noma okuphuzi, okunokumelana okunamandla nesimo sezulu.
Ukugqoka kwe-zinc + asphalt: udonga olumnyama lwangaphandle, olufanele amapayipi agqitshwe.
4. Isifinyezo: Ungakhetha kanjani umbala wamapayipi ensimbi acishiwe?
Khetha ngokusebenzisa:
Amanzi okuhambisa amanzi/indle → omnyama/ompunga
Amanzi okuphuza → oluhlaza/oluhlaza okwesibhakabhaka
Ukucisha umlilo → okubomvu
Imboni → ngokuhlonza okuphakathi (njengegesi ephuzi, umoya ocindezelwe oluhlaza okwesibhakabhaka)
Khetha ngokwejwayelekile:
IShayina (GB) → omnyama (imisele yamanzi), obomvu (ukucisha umlilo), oluhlaza (amanzi okuphuza)
IYurophu ne-United States (AWWA/EN) → omnyama (ongamelani nokugqwala kwangaphandle), oluhlaza/oluhlaza okwesibhakabhaka (ulwelwesi)
IJapan (JIS) → omnyama (udonga lwangaphandle), obomvu (ukucisha umlilo)
Uma ungakakwazi ukukhetha, sicela uxhumane no-D.I-INSEN
