Brief sumo
Ductile iron pipe imhando yepombi yesimbi yakakandwa.Panyaya yemhando, iyo spheroidization giredhi ye cast iron pombi inodiwa kuti idzorerwe kusvika ku1-3 mamakisi (spheroidization rate> 80%), saka michina yemidziyo yacho pachayo yakagadziridzwa zvirinani, nehunhu hwesimbi uye zvinhu zvesimbi.Iyo metallographic chimiro cheiyo annealed ductile iron pombi ndeye ferrite pamwe nediki diki pearlite.Iine yakanaka ma mechanical properties, yakanakisa corrosion resistance, good ductility, good sealing effect, nyore kuisa, uye inonyanya kushandiswa kugovera mvura, kutapurirana gasi, kutapurirana mafuta, etc. mumanisipala, maindasitiri nemabhizimusi emigodhi.
Imwe huwandu hwe spherical graphite inogoverwa pane ferrite uye pearlite matrix.Zvinoenderana neyakasiyana dhayamita yezita uye zvinodiwa pakurebesa, chikamu cheferrite uye pearlite mune matrix chimiro chakasiyana.Chiyero chepearlite ine dhayamita diki kazhinji hachipfuuri 20%, uye icho chedhayamita hombe chinowanzodzorwa chingangoita 25%.
Performance zve ductile iron pipe
Ductile iron pombi imhando yesimbi yakakandwa, inova alloy yesimbi, kabhoni uye nesilicon.Graphite mune spheroidal graphite cast iron iripo muchimiro che spheroidal graphite.Kazhinji, saizi yegraphite ndeye 6-7, uye giredhi re spheroidization yepombi yakakandwa inofanirwa kudzorwa ku1-3 (spheroidization rate ≥ 80%) maererano nemhando.Nokudaro, iyo mechanical properties yezvinyorwa pachayo yakagadziridzwa zviri nani, nemhando yesimbi uye zvinhu zvesimbi.Iyo metallographic chimiro cheiyo annealed ductile iron pombi ndeye ferrite pamwe nediki diki pearlite, uye ayo emakanika maitiro akanaka.
Ductile iron pombi inonyanya kunzi centrifugal ductile iron pipe.Iyo ine hunhu hwesimbi, kuita kwesimbi, yakanakisa corrosion resistance, yakanaka ductility, yakanaka yekuisa chisimbiso, nyore kuisa, uye inonyanya kushandiswa kugovera mvura, kutapurirana gasi, kutapurirana mafuta, nezvimwewo mumanisipala, maindasitiri uye mabhizinesi emigodhi.Ndiyo yekutanga kusarudzwa kwepombi dzemvura ine mari yakawanda yekuita.Kuenzaniswa nePE pombi, nguva yekuisa ductile iron pombi iri nyore uye nekukurumidza kupfuura PE pombi, uye mukati nekunze kutakura kumanikidza kuri nani mushure mekuiswa;Kubva pakuona kwekudzivirira kwemhepo uye kushorwa kwemhepo, mhepo ye spheroidal graphite pipe mushure mekuiswa zviri nani, uye kupikisa kwehutu kunogonawo kuvandudzwa nenzira dzakasiyana-siyana dzekudzivirira-corrosion;Kubva pane hydraulic performance point yekuona, nekuti iyo dhizaini ye ductile iron pombi kazhinji inoreva dhayamita yemukati, iyo PE pombi inowanzoreva dhayamita rekunze, nekuti pasi pemamiriro akafanana ekutemerwa, iyo ductile iron pombi inogona kuwana yakakura runoff;Kubva pamaonero ehuwandu hwekuisa nekugadzirisa mitengo, iyo ductile iron pombi ine mutengo uri nani kuita.Rusvingo rwemukati rwakapfapfaidzwa ne zinc, simende mortar anti-corrosion materials, nezvimwewo.

Sarudzo mazano zve ductile iron pipe
1. Kusarudzwa kwe ductile iron pipes kuchave kwakavakirwa pamamiriro chaiwo enzvimbo yekuisa, uye chimiro chechimiro chepombi dzakatwasuka uye fittings ichasarudzwa.
2. Mhete yerabha inowanzogadzirwa neNBR, SBR, EPDM nezvimwe zvinhu.
3. Kusarudzwa kwekuputira: sarudza jira rakakodzera maererano nemamiriro emukati nekunze panguva yekushandiswa.Iyo iripo yemukati yemukati ndeye epoxy resin, polyurethane yemukati uye yekunze coating, PE film coating uye zvimwe zvigadzirwa zvitsva zve ductile iron pipe, uye kuita kwayo kunofanirwa kunzwisiswa zvakadzama pakusarudza.
Zvakanakira nezvayakaipira zve ductile iron pipe
Advantage
Ductile iron mapaipi anoshandiswa mukati uye yakaderera kumanikidza pombi network (inowanzo shandiswa pazasi 6MPa).Ductile iron mapaipi ane mashandiro akachengeteka uye akavimbika, mwero wakaderera wekukuvara, nyore uye nekukurumidza kuvaka uye kugadzirisa, uye yakanakisa corrosion kuramba.Iyo ichangobva kugadzirwa "Yandun" yakatevedzana pombi inogona kuiswa kune trenchless kuvaka uye kushandiswa zvakanyanya mukuvaka pombi mhiri kwenzizi, migwagwa uye zvivakwa.Iyo "Saizin" yakatevedzana pombi inoshandisa yakakosha zinc aluminium alloy yekunze kupfapfaidza maitiro kunatsiridza kusaora kwepombi kakawanda, uye inoshandiswa zvakanyanya mukuvaka ivhu rinoora zvakanyanya.
Diadvantage
Kazhinji, haishandiswe mu-high-pressure pombi network (pamusoro pe6MPa).Nekuti iyo pombi muviri inorema, michina inofanirwa kushandiswa panguva yekuisa.Kana paine kubuda kwemvura mushure mekuyedzwa kwekumanikidza, pombi dzese dzinofanirwa kucherwa kunze, mapaipi anofanirwa kusimudzwa kusvika pakakwirira paanogona kuiswa mumaclamps, uye machira anoiswa kudzivirira kubuda kwemvura.
Isu JINBAICHENG isimwe yemugadziri ane mukurumbira, mutengesi, stockist, stockholder uye mutengesi weductile iron pipe.Tine mutengi kubva kuMexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab, Vietnam, Myanmar, German, etc.
