Nhau - Ductile Iron Pipe: The Mainstay of Modern Pipeline Systems

Ductile Iron Pipe, inogadzirwa nesimbi yakaumbwa sechinhu chepasi. Asati adira, magnesium kana isingawanzo pasi magnesium uye mamwe ma spheroidizing agents anowedzerwa kune yakanyungudutswa simbi kuti spheroidize graphite, uye ipapo pombi inogadzirwa kuburikidza nenhevedzano yemaitiro akaomarara. Iyo yakasarudzika ye ductile iron ndeyekuti yakawanda kana yese yeiyo precipitated graphite iri mune spherical fomu, uye ichi chimiro chechimiro chinovandudza zvakanyanya mashandiro echinyorwa. Mushure mekuvhara, iyo metallographic chimiro cheBlack Iron Tubeis ferrite pamwe nediki pearlite, uye ma mechanical properties akanaka. .

Nhoroondo yebudiriro yeDuctile Iron Tubeizere nehunyanzvi uye kubudirira. Mukupera kwema1980 uye kutanga kwema1990, yakatarisana nekuvharirwa kwekunze centrifugal ductile iron pombi yekugadzira tekinoroji uye yakaoma mvumo yemvumo yemvumo, iyo 2672nd Factory yeChinese People's Liberation Army (akatangira Xinxing Casting Pipe) akashinga kuita basa rekutsvaga akazvimirira nekusimudzira. Muna 1993, yekutanga centrifugal ductile iron pombi muChina yakasimudzwa zvakabudirira kubva pamutsetse wekugadzira, zvichiratidza kuti nyika yangu yawana kusvetuka kubva mukutanga mundima iyi, uye zvakatora makore masere chete kupedzisa 40-makore ekusimudzira nyika dzekuMadokero. Nhasi, Xinxing Casting Pipe yakagadzirika kuita yakakura uye ine simba kwazvo centrifugal ductile iron mugadziri wepombi, uye yakatorawo chikamu mukugadzirwa kwepasirese pombi miyero, ichienderera mberi nekusimudzira kusimudzira kweindasitiri yepombi yesimbi.

Ductile Iron Pipes Ane Kusiyana Kwemaitiro Ekuita

1. Kusimba Kwakakwirira uye Kusimba Kwakanaka: Ductile iron mapaipi ane simba rakawanda, uye simba rawo rinovandudzwa zvakanyanya kana zvichienzaniswa neakajairwa simbi pombi. Nekuti graphite yakagovaniswa muchimiro chedenderedzwa, iyo kupatsanurwa kweiyo matrix inodzikiswa, zvichiita kuti pombi isanyanya kutsemuka kana ichiiswa mukumanikidzwa kukuru uye kukanganisa. Panguva imwecheteyo, inewo kuoma kwakanaka, nekurebesa kwakawanda kupfuura 10%, uye inogona kuchinjika kune pasi subsidence, kufamba kwevhu uye mamwe mamiriro kusvika pamwero wakati. Hazvisi nyore kukuvadzwa ne deformation, iyo inovandudza kuvimbika kwepombi network kushanda

2. Strong Corrosion Resistance: Kuburikidza neakasiyana-siyana ekurwisa-corrosion maitiro ekurapa, senge asphalt pendi yekuputira, simende dhaka lining, epoxy marasha tar coating, epoxy ceramic lining, aluminate simende coating, sulfate simende coating uye polyurethane coating, ductile iron mapaipi anogona zvinobudirira kuramba ngura kubva kune akasiyana midhiya. Kunyangwe ichishandiswa kutakura gasi, mvura yemupombi, kana yekurasa tsvina, inogona kuchengetedza kushanda kwakadzikama munzvimbo dzakasiyana dzakaoma, kuwedzera hupenyu hwesevhisi yepombi, uye kuderedza mari yekugadzirisa. .
3. Kuiswa Chisimbiso Kwakanaka: Muromo wepombi unotora chimiro chinochinjika, chinogona kuchinjika kuchinjika uye deformation mukati meimwe mhando, kuumba yakanaka yekuisa chisimbiso pachikamu chekubatanidza pombi, uye zvinobudirira kudzivirira kubuda kwemvura. Panguva imwecheteyo, iyo yepamusoro-chaiyo yekugadzira nzira yepombi pachayo inovimbisa kuenderana kweiyo socket, inowedzera kunatsiridza kuita chisimbiso, uye inovimbisa kushanda kwakachengeteka kwepipeline system. .
4. Easy Installation: Kuenzaniswa nemamwe mapaipi, huremu hwe ductile iron pombi huri pakati nepakati, uye nzira yekuisa iri nyore. Yayo inoshanduka interface inogonesa vashandi vekuvaka kuita basa rekubatanidza, kuderedza nguva yekuisa uye kusimba kwekushanda. Panzvimbo yekuvaka, kuiswa kwepombi kunogona kupedzwa nekukurumidza pasina michina yakaoma uye nyanzvi dzehunyanzvi, izvo zvinopfupisa zvakanyanya kutenderera kweprojekiti uye inovandudza kushanda kwekuvaka. .
5. Yakanaka Antifreeze Performance: Munzvimbo dzinotonhora, iyo antifreeze kuita kwepombi kwakakosha. Ductile iron pombi dzine imwe dhigirii ye antifreeze. Chero bedzi isiri nharaunda yakaoma zvakanyanya, pachave pasina kutsemuka kwechando uye kuputika. Izvi zvinoita kuti ishandiswe zvakanyanya mukugovera mvura, kudziyisa uye mamwe mapaipi masisitimu munzvimbo dzinotonhora dzekuchamhembe, ichipa masevhisi akavimbika kune vagari nemabhizinesi. .

Ductile Iron Mvura Pipevave chinhu chakakosha uye chakakosha pombi zvinhu mukuvaka zvivakwa zvemazuva ano nemaitiro avo ekuita zvakanaka. Kubva pakuwanisa mvura yemumaguta nekugezeswa kwemvura kusvika pakufambiswa kwegasi, kubva mukugadzirwa kwemaindasitiri kuenda kumapurojekiti ekuchengetedza mvura, pombi dzesimbi dzemaductile dzinoita basa rakakosha munzvimbo dzakasiyana siyana uye dzakaita zvakakosha kuti ive nechokwadi chehupenyu hwevanhu uye kusimudzira kusimukira kwehupfumi. Nekuenderera mberi nekufambira mberi uye hunyanzvi hwehunyanzvi, kuita kwepombi dzesimbi dze ductile kucharamba kuchivandudza, uye huwandu hwekushandisa huchawedzerwa. Vacharamba vachipenya mukuvakwa kwezvivakwa mune ramangwana. .
