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

Pipe ea Tšepe ea Ductile, e entsoe ka tšepe e entsoeng ka tšepe e le thepa ea motheo. Pele o tšela, magnesium kapa lefatše le sa tloaelehang la magnesium le lisebelisoa tse ling tsa spheroidizing li kenngoa ka tšepe e qhibilihisitsoeng ho etsa graphite spheroidize, ebe phala e hlahisoa ka letoto la mekhoa e rarahaneng. Ntho e ikhethang ea tšepe ea ductile ke hore boholo ba graphite e nang le metsi a mangata kapa kaofela e ka sebopeho sa spherical, 'me tšobotsi ena ea sebopeho e ntlafatsa haholo ts'ebetso ea thepa. Ka mor'a annealing, sebopeho metallographic eaTube ea Tšepe e Ntšoke ferrite hammoho le palo e nyane ea pearlite, 'me thepa ea mochini e ntle. .

Nalane ea tsoelopele eaTube ea tšepe ea ductilee tletse ka boqapi le likhatelopele. Ho elella bofelong ba lilemo tsa bo-1980 le mathoasong a lilemo tsa bo-1990, ho tobane le thibelo ea theknoloji ea tlhahiso ea liphaephe tsa tšepe ea centrifugal e tsoang linaheng tse ling le maemo a thata a tumello ea tumello ea molao, Fektheri ea 2672 ea Sesole sa Tokoloho sa Batho ba Chaena (pele ho Xinxing Casting Pipe) ka sebete se ile sa nka mosebetsi oa ho etsa lipatlisiso le nts'etsopele e ikemetseng. Ka 1993, phala ea pele ea tšepe ea centrifugal ductile Chaena e ile ea phuthoa ka katleho moleng oa tlhahiso, ho tšoaea hore naha ea heso e finyelletse ho tloha qalong tšimong ena, 'me ho nkile lilemo tse robeli feela ho phethela ts'ebetso ea lilemo tse 40 tsa ntlafatso ea linaha tsa Bophirimela. Kajeno, Xinxing Casting Pipe e tsoetse pele ho ba moetsi oa liphaephe tsa tšepe tse kholo ka ho fetisisa le tse matla ka ho fetisisa lefatšeng, hape e nkile karolo ho thehoeng ha litekanyetso tsa liphaephe tsa lefats'e, e tsoelang pele ho khothaletsa nts'etsopele ea indasteri ea phala ea tšepe ea ductile.

Liphaephe tsa Iron tsa Ductile li na le Mefuta e sa tšoaneng ea Litšobotsi tsa Ts'ebetso

1. Matla a Phahameng le Matla a Molemo: Liphaephe tsa tšepe tsa ductile li na le matla a phahameng, 'me matla a tsona a ntlafala haholo ha a bapisoa le liphaephe tse tloaelehileng tsa tšepe. Hobane graphite e ajoa ka sebopeho se chitja, phello e arohaneng holim'a matrix e ea fokotseha, e leng se etsang hore phala e se ke ea robeha ha e le tlas'a khatello le tšusumetso e kholo. Ka nako e ts'oanang, e boetse e na le boima bo botle, ka bolelele bo boholo ho feta 10%, 'me e khona ho ikamahanya le ho theoha ha mobu, ho sisinyeha ha mobu le maemo a mang ho isa tekanyong e itseng. Ha ho bonolo ho senngoa ke deformation, e ntlafatsang ts'epahalo ea ts'ebetso ea marang-rang ea liphaephe

2. Khanyetso e Matla ea Corrosion: Ka mekhoa e fapaneng ea phekolo e khahlanong le kutu, e kang ho roala pente ea asphalt, lesela la seretse sa samente, lesela la mashala a epoxy, lesela la epoxy ceramic, lesela la samente la aluminate, lesela la samente la sulfate le ho roala ha polyurethane, liphaephe tsa tšepe tsa ductile li ka hanela kutu ho tsoa mecheng e fapaneng ea litaba. Ebang e sebelisetsoa ho tsamaisa khase, metsi a pompo, kapa ho ntša likhoerekhoere, e ka boloka ts'ebetso e tsitsitseng libakeng tse fapaneng tse rarahaneng, ea atolosa bophelo ba tšebeletso ea lipeipi, le ho fokotsa litšenyehelo tsa tlhokomelo. .
3. Ho Tiisa ho Molemo: Molomo oa pipe o amohela sebopeho se feto-fetohang, se ka ikamahanyang le ho falla le ho senyeha ka har'a mefuta e itseng, ho theha phello e ntle ea ho tiisa karolong ea ho hokahanya ha pipe, 'me ka katleho ho thibela ho tsoa ha metsi. Ka nako e ts'oanang, ts'ebetso e phahameng ea tlhahiso ea phala ka boeona e tiisa ho nepahala ho ts'oanang ha sokete, ho ntlafatsa ts'ebetso ea ho tiisa, le ho netefatsa ts'ebetso e sireletsehileng ea tsamaiso ea liphaephe. .
4. Ho Hlophisa Bonolo: Ha ho bapisoa le liphaephe tse ling, boima ba liphaephe tsa tšepe tsa ductile bo batla bo lekanyelitsoe, 'me mokhoa oa ho kenya o batla o le bonolo. Sebopeho sa eona se feto-fetohang se thusa basebetsi ba kaho ho etsa ts'ebetso ea ho hokahanya, ho fokotsa nako ea ho kenya le matla a mosebetsi. Sebakeng sa kaho, ho kenngoa ha liphaephe ho ka phethoa ka potlako ntle le lisebelisoa tse rarahaneng le litsebi tsa litsebi, tse khutsufatsang haholo potoloho ea morero le ho ntlafatsa katleho ea kaho. .
5. Ts'ebetso e ntle ea Antifreeze: Libakeng tse batang, ts'ebetso ea antifreeze ea liphaephe e bohlokoa. Lipeipi tsa tšepe tsa ductile li na le tekanyo e itseng ea antifreeze. Hafeela e se tikoloho e thata ka ho fetisisa, ha e le hantle ho ke ke ha e-ba le mapetsong a leqhoa le ho phatloha. Sena se etsa hore e sebelisoe haholo phepelong ea metsi, ho futhumatsa le lits'ebetso tse ling tsa lipeipi libakeng tse batang tse ka leboea, ho fana ka lits'ebeletso tse tšepahalang ho baahi le likhoebo. .

Pipe ea Metsi a Tšepe ea ductileli fetohile thepa ea bohlokoa le ea bohlokoa ea liphaephe mohahong oa mekhoa ea morao-rao ea mekhoa e metle ka litšobotsi tsa bona tse babatsehang tsa ts'ebetso. Ho tloha phepelong ea metsi litoropong le ho tsamaisa metsi ho isa phetisong ea khase, ho tloha tlhahisong ea indasteri ho isa mererong ea paballo ea metsi, lipeipi tsa tšepe tse tsamaisang metsi li bapala karolo ea bohlokoa mafapheng a fapaneng 'me li entse tlatsetso ea bohlokoa ho netefatsa boleng ba bophelo ba batho le ho khothaletsa nts'etsopele ea moruo. Ka tsoelo-pele e tsoelang pele le boqapi ba theknoloji, ts'ebetso ea liphaephe tsa tšepe ea ductile e tla tsoela pele ho ntlafala, 'me sebaka sa ts'ebeliso se tla atolosoa le ho feta. Ba tla tswela pele ho kganya kahong ya meralo ya kamoso. .
