Kodi Ductile Iron Pipe Imalemera Zambiri Motani​

Mu uinjiniya wa madzi ndi ngalande, maukonde a mapaipi a m'matauni, ndi machitidwe a mapaipi a mafakitale,chitoliro chachitsulo chosungunukachakhala cholowa m'malo mwa mapaipi achitsulo ndi zitsulo zachikhalidwe chifukwa cha mphamvu zake zabwino kwambiri zamakaniko komanso kukana dzimbiri. Kumvetsetsa magawo ofunikira aukadaulo a mapaipi achitsulo opangidwa ndi ductile ndikofunikira kwambiri kwa opanga mapulani, ogula, ndi makampani omanga, kaya pa malo operekera madzi kapena zoyendera zimbudzi. Nkhaniyi ifotokoza zaDINSEN ductile chitsulo chitoliromonga chitsanzo chofotokozera mwadongosolo tsatanetsatane wake, kulemera kwake, kuthamanga kwa ntchito, ndi mawonekedwe ake okutira.

I. Mafotokozedwe ndi Miyeso ya Chitoliro cha Chitsulo cha Ductile ndi Chitsulo: Kodi Mungadziwe Bwanji Chitsanzo?

Posankha mapaipi, choyamba ndikofunikira kufotokoza kukula ndi kukula kwa mapaipi achitsulo opangidwa ndi ductile. Miyezo yapadziko lonse lapansi imachokera makamaka ku ISO 2531 kapena EN 545, yomwe imagawidwa ndi mainchesi odziwika (DN).

Potengera chitoliro chachitsulo cha DINSEN chopangidwa ndi ductile, mapaipi a K9 grade (standard wall thickness level) amagwiritsidwa ntchito kwambiri, okhala ndi mainchesi oyambira DN80 mpaka DN2000. Nayi kukula kwa mapaipi wamba:

• DN80: M'mimba mwake wakunja 98mm, makulidwe a khoma 6.0mm
• DN100: M'mimba mwake wakunja 118mm, makulidwe a khoma 6.0mm
• DN200: M'mimba mwake wakunja 222mm, makulidwe a khoma 6.3mm
• DN400: M'mimba mwake wakunja 429mm, makulidwe a khoma 8.1mm
• DN1000: M'mimba mwake wakunja 1048mm, makulidwe a khoma 13.5mm

Magulu osiyanasiyana a makulidwe a khoma (K8, K9, K10, K12) adzakhudza mphamvu yonyamula mphamvu ndi kulemera kwa chitolirocho.Ogwiritsa ntchito amatha kusankha moyenera malinga ndi kapangidwe kake.

II. Kulemera pa mita imodzi ya chitoliro chachitsulo chopopera: Kodi chitoliro chachitsulo chopopera chimalemera zingati?

Funso lofala kwambiri pakugula kwa uinjiniya ndi lakuti: Kodi chitoliro chachitsulo chopangidwa ndi ductile chimalemera zingati? Kulemera kwa chitoliro chachitsulo chopangidwa ndi ductile kumaphatikizapo kulemera kwa thupi la chitoliro ndi kulemera kwa soketi, zomwe zimakhudza mwachindunji mayendedwe, kukweza, ndi ndalama zoyikira.

Potengera chitoliro chachitsulo cha DINSEN K9 grade ductile (kutalika kwa mita 6) mwachitsanzo, kulemera kwa chiphunzitso ndi motere:

• DN100: Pafupifupi 15.1 kg/m → 95 kg pa chitoliro chilichonse
• DN200: Pafupifupi 30.6 kg/m → 194 kg pa chitoliro chilichonse
• DN300: Pafupifupi 50.8 kg/m → 323 kg pa chitoliro chilichonse
• DN500: Pafupifupi 104.3 kg/m → 669 kg pa chitoliro chilichonse
• DN800: Pafupifupi 215.2 kg/m → 1394 kg pa chitoliro chilichonse

Kulemera kwenikweni kungasiyane pang'ono chifukwa cha zinthu monga makulidwe a zinc coating ndi mkati mwa simenti matope. DINSEN ikhoza kupereka mapepala olondola owerengera kulemera kwa polojekiti komanso kukonzekera zinthu.

III. Kupanikizika kwa Ntchito kwa Chitoliro cha Chitsulo Chopangidwa ndi Ductile

Chitoliro chachitsulo chozungulira chimakhala ndi mphamvu yokoka kwambiri komanso mphamvu yozungulira. Chitoliro chachitsulo chozungulira ...

Mapaipi achitsulo a DINSEN opangidwa motsatira miyezo ya ISO 2531. Chitoliro chilichonse chimayesedwa ndi hydrostatic chisanatuluke mufakitale kuti chitsimikizire kuti chili ndi mphamvu yotetezeka yokwana 1.5 kuposa mphamvu yogwirira ntchito, zomwe zimapangitsa kuti zikhale zoyenera kwambiri potumiza madzi kutali, mapaipi okweza malo opopera madzi, ndi mapaipi amafakitale opanikizika kwambiri.

IV. Zinc Coating Yoteteza Kudzimbiri

Ntchito ya Zinc Coating pa Mapaipi a Chitsulo cha Ductile Chimodzi mwa njira zofunika kwambiri zotetezera mapaipi obisika ndi zinc coating pa mapaipi a chitsulo cha ductile. Zinc coating sikuti imangopereka chitetezo cha cathodic komanso imapanga njira yotsutsana ndi dzimbiri yokhala ndi utoto wakunja kapena polyethylene sheathing.

Mapaipi achitsulo a DINSEN okhala ndi ductile amabwera ndi chivundikiro cha zinc cha ≥200 g/m² (malinga ndi muyezo wa ISO 8179), chophimbidwa ndi asphalt wofiira wa epoxy kapena polyurethane, zomwe zimapangitsa kuti kukana dzimbiri kukhale kolimba komanso kukhala ndi moyo wautali. Pa dothi lowononga kapena madera otetezedwa kwambiri, chivundikiro chowonjezera cha zinc + filimu ya PE kapena chivundikiro chonse cha polyurethane chikupezeka, chokhala ndi moyo wopangidwa wa zaka 50-100.

V. N’chifukwa Chiyani Muyenera Kusankha Mapaipi a Chitsulo a DINSEN Ductile?

Monga wogulitsa mapaipi achitsulo opangidwa ndi ductile, DINSEN imapereka mitundu yonse ya zinthu kuyambira DN80 mpaka DN2000, zomwe zimathandiza makulidwe osiyanasiyana a makoma monga K8, K9, K10, ndi K12, ndipo imatha kusintha kutalika, zophimba zamkati (simenti/epoxy resin), ndi njira zodzitetezera ku dzimbiri zakunja kuti zikwaniritse zosowa za makasitomala.

Mapaipi onse achitsulo opangidwa ndi ductile ali ndi satifiketi ya ISO 2531 / EN 545. Matebulo athunthu a kulemera, miyeso, kuthamanga kwa ntchito, ndi magawo okutira zinc alipo. Ma phukusi ochokera kunja kwa dziko lapansi ndi ntchito zoyendera zinthu nthawi imodzi zimathandizidwa.

Kuti mudziwe zambiri za kukula ndi miyeso ya mapaipi achitsulo opangidwa ndi ductile, matebulo osankhiramo kapena zida zowerengera kulemera, chonde pitani ku tsamba lawebusayiti.DINSENkapena funsani gulu la ogulitsa mwaluso mwachindunji.
