Mitundu ya Iron Pipe ndi Zofunikira Zapadera Pamisika

Mtundu wakuponya mapaipi achitsulonthawi zambiri zimagwirizana ndi kugwiritsa ntchito kwawo, mankhwala odana ndi dzimbiri kapena miyezo yamakampani. Mayiko ndi mafakitale osiyanasiyana atha kukhala ndi zofunikira zenizeni zamitundu kuti zitsimikizire chitetezo, kukana dzimbiri kapena kuzizindikira mosavuta. Nawa gulu latsatanetsatane:

1. Tanthauzo lalikulu la mtundu wa DINSEN SML Pipe

·Wakuda/wotuwa wakuda/Chitsulo choyambirira kapena phula/anti-corrosion № Ngalande, zimbudzi, mapaipi a tauni

·Chofiira/Mapaipi amoto, kukana kutentha kwakukulu kapena zizindikiro zapadera/Dongosolo lamoto, kuthamanga kwamadzi kwamphamvu

·Green/Mapaipi amadzi akumwa, zokutira zoteteza zachilengedwe (monga epoxy resin)/Madzi apampopi, chakudya kalasi madzi

·Buluu/Madzi a mafakitale, mpweya woponderezedwa/Fakitale, wothinikizidwa mpweya dongosolo

·Yellow/Mapaipi a gasi (chitsulo chochepa kwambiri, makamaka mapaipi achitsulo)/Kutumiza kwa gasi (malo ena amagwiritsabe ntchito chitsulo chotayirira)

·Siliva/Mankhwala odana ndi dzimbiri/Kunja, malo achinyezi, zofunika kukana dzimbiri

2. Zofunikira zapadera zamitundu yachitsulo choponyera chitoliro m'misika yapakhomo ndi yakunja 

(1) Msika waku China (GB standard)

Mipope ya Iron ya Drainage: nthawi zambiri yakuda (asphalt anti-corrosion) kapena chitsulo choyambirira chotuwa, chokutidwa pang'ono ndi epoxy resin (yobiriwira).

Paipi Yachitsulo Yopangira Madzi:Chitoliro chachitsulo chachitsulo: chakuda kapena chofiira (choteteza moto).

Ductile Iron Pipe (DN80-DN2600): khoma lakunja lopopera ndi nthaka + asphalt (wakuda), mkati mwake ndi simenti kapena epoxy resin (imvi / zobiriwira).

Chitoliro Choteteza Moto: zokutira zofiyira, mogwirizana ndi chitetezo chamoto cha GB 50261-2017.

Chitoliro cha Gasi: chikasu (koma mapaipi amakono a gasi amapangidwa makamaka ndi PE kapena mapaipi achitsulo, ndipo chitsulo choponyedwa sichimagwiritsidwa ntchito kawirikawiri).

(2) Msika waku US (AWWA/ANSI Standard)

AWWA C151 (chitoliro chachitsulo cha ductile):
Khoma lakunja: nthawi zambiri zakuda (zopaka phula) kapena siliva (malata).
Mkati mwake: matope a simenti (imvi) kapena epoxy resin (wobiriwira/buluu).

Chitoliro Choteteza Moto (NFPA standard): chizindikiro chofiira, ena amafuna kuti mawu oti "FIRE SERVICE" asindikizidwe.

Chitoliro cha Madzi Omwa (NSF / ANSI 61 certification): chiwongolero chamkati chiyenera kukwaniritsa miyezo yaukhondo, palibe chofunikira chovomerezeka cha mtundu wakunja wa khoma, koma logo yobiriwira kapena yabuluu imagwiritsidwa ntchito nthawi zambiri.

(3) Msika waku Europe (EN muyezo)

EN 545/EN 598 (paipi yachitsulo ya ductile):

Kunja Anticorrosion: zinki + phula (wakuda) kapena polyurethane (wobiriwira).

Inner Lining: matope a simenti kapena epoxy resin, palibe malamulo okhwima amtundu, koma ayenera kutsata miyezo ya madzi akumwa (monga chiphaso cha KTW).

Chitoliro cha Moto: chofiira (maiko ena amafuna kusindikiza "FEUER" kapena "MOTO").

Chitoliro cha mafakitale: chingakhale cha buluu (mpweya wothinikizidwa) kapena wachikasu (gasi, koma mapaipi achitsulo asinthidwa pang'onopang'ono).

(4) Japan msika (JIS muyezo)

JIS G5526 (chitoliro chachitsulo cha ductile): Khoma lakunja nthawi zambiri limakhala lakuda (asphalt) kapena malata (siliva), ndipo mkati mwake ndi simenti kapena utomoni.

Chitoliro chamoto: kujambula kofiira, zina zimafuna kusindikiza "kumenyana ndi moto".

Chitoliro chamadzi chakumwa: zobiriwira kapena zabuluu, mogwirizana ndi muyezo wa JHPA.

3. Chikoka cha mtundu wa zokutira zapadera zotsutsana ndi dzimbiri

Kupaka utomoni wa epoxy: nthawi zambiri wobiriwira kapena wabuluu, womwe umagwiritsidwa ntchito pazinthu zotsutsana ndi dzimbiri (monga madzi a m'nyanja, makampani opanga mankhwala).
Chophimba cha polyurethane: chikhoza kukhala chobiriwira, chakuda kapena chachikasu, chotsutsana ndi nyengo.
Kupaka kwa Zinc + asphalt: khoma lakunja lakuda, loyenera mapaipi okwiriridwa.

4. Mwachidule: Kodi mungasankhe bwanji mtundu wa mapaipi achitsulo?

Sankhani pogwiritsa ntchito:
Ngalande/zonyansa → zakuda/zotuwa
Madzi akumwa → wobiriwira/buluu
Kuzimitsa moto → wofiira
Makampani → ndi chizindikiritso chapakati (monga mpweya wachikasu, mpweya woponderezedwa wabuluu)

Sankhani malinga ndi muyezo:
China (GB) → wakuda (ngalande), wofiira (kuzimitsa moto), wobiriwira (madzi akumwa)
Europe ndi United States (AWWA/EN) → wakuda (wodana ndi dzimbiri), wobiriwira/buluu (mzere)
Japan (JIS) → wakuda (khoma lakunja), wofiira (wozimitsa moto)
