Bisingeniso esimnandi
Ipayipi le-iron ductile luhlobo lwepayipi yensimbi ekhonjiwe.Ngokwekhwalithi, izinga le-spheroidization yepayipi lensimbi ensimbi liyadingeka ukuthi lilawulwe libe ku-1-3 amamaki (izinga le-spheroidization>80%), ngakho-ke izakhiwo zemishini yento ngokwayo ziye zathuthukiswa kangcono, ngohlobo lwensimbi nensimbi. izakhiwo zensimbi.Isakhiwo se-metallographic sepayipi le-iron ductile annealed yi-ferrite kanye nenani elincane le-pearlite.Inezakhiwo ezinhle zemishini, ukumelana nokugqwala okuhle kakhulu, i-ductility enhle, umphumela omuhle wokuvala, ukufakwa kalula, futhi isetshenziselwa ikakhulukazi ukuhlinzeka ngamanzi, ukuhanjiswa kwegesi, ukuthuthwa kukawoyela, njll. kumabhizinisi kamasipala, izimboni kanye nezimayini.
Inani elithile le-graphite eyindilinga lisatshalaliswa ku-matrix ye-ferrite ne-pearlite.Ngokobubanzi obuhlukile begama kanye nezidingo zokwelula, ingxenye ye-ferrite ne-pearlite esakhiweni se-matrix ihlukile.Ingxenye ye-pearlite enobubanzi obuncane ngokuvamile ayibi ngaphezu kuka-20%, futhi ubukhulu bayo obukhulu ngokuvamile ilawulwa cishe ku-25%.
Pukusebenza kahle kwe ductile iron pipe
I-Ductile iron pipe iwuhlobo lwe-cast iron, okuyingxubevange yensimbi, i-carbon ne-silicon.I-graphite e-spheroidal graphite cast iron ikhona ngendlela ye-spheroidal graphite.Ngokuvamile, ubukhulu be-graphite bungu-6-7, futhi ibanga le-spheroidization lepayipi elikhonjiwe liyadingeka ukuthi lilawulwe ku-1-3 (izinga le-spheroidization ≥ 80%) ngokwekhwalithi.Ngakho-ke, izakhiwo zemishini yezinto ngokwazo ziye zathuthukiswa kangcono, ngemvelo yensimbi kanye nezakhiwo zensimbi.Isakhiwo se-metallographic sepayipi yensimbi ye-annealed ductile yi-ferrite kanye nenani elincane le-pearlite, futhi izici zayo zemishini zinhle.
Ipayipi lensimbi elidonsayo libizwa ngokuyinhloko ngokuthi ipayipi lensimbi eliyi-centrifugal ductile.Inesimo sensimbi, ukusebenza kwensimbi, ukumelana nokugqwala okuhle kakhulu, i-ductility enhle, umphumela omuhle wokuvala uphawu, ukufakwa kalula, futhi isetshenziselwa ikakhulukazi ukuhlinzeka ngamanzi, ukuhanjiswa kwegesi, ukudluliswa kukawoyela, njll kumabhizinisi kamasipala, izimboni kanye nezimayini.Kuwukukhetha kokuqala kwamapayipi okuhambisa amanzi anezindleko eziphezulu zokusebenza.Uma kuqhathaniswa nepayipi le-PE, isikhathi sokufakwa kwepayipi yensimbi ye-ductile silula futhi sishesha kunepayipi ye-PE, futhi ingcindezi yokuthwala yangaphakathi nangaphandle ingcono ngemva kokufakwa;Ngokombono we-airtightness kanye nokumelana nokugqwala, ukungena komoya kwepayipi le-spheroidal graphite ngemva kokufakwa kungcono, futhi ukumelana nokugqwala kungabuye kuthuthukiswe ngezindlela ezihlukahlukene zokulwa nokubola;Ngokombono wokusebenza kwe-hydraulic, ngenxa yokuthi ukucaciswa kwepayipi lensimbi ye-ductile ngokuvamile kubhekisela kububanzi bangaphakathi, ukucaciswa kwepayipi le-PE ngokuvamile kubhekisela kububanzi obungaphandle, ngoba ngaphansi kwezimo ezifanayo zokucaciswa, ipayipi lensimbi ye-ductile lingafinyelela ukugeleza okukhulu;Ngokombono wezindleko eziphelele zokufaka nokunakekela, ipayipi le-iron ductile linokusebenza okungcono kwezindleko.Udonga lwangaphakathi lufafazwa nge-zinc, i-cement mortar anti-corrosion materials, njll.

Iziphakamiso zokukhetha kwe ductile iron pipe
1. Ukukhethwa kwamapayipi e-iron ductile kufanele kusekelwe ezimweni ezithile zendawo yokubeka, futhi ifomu lesixhumi esibonakalayo lamapayipi aqondile kanye nokufakwa kuzokhethwa.
2. Indandatho yerabha ngokuvamile yenziwe nge-NBR, SBR, EPDM nezinye izinto.
3. Ukukhethwa kokugqoka: khetha ukugqoka okufanele ngokuvumelana nezimo zangaphakathi nezangaphandle ngesikhathi sokusetshenziswa.I-coating yangaphakathi ekhona i-epoxy resin, i-polyurethane yangaphakathi nangaphandle yokugqoka, ifilimu yefilimu ye-PE kanye neminye imikhiqizo emisha yepayipi yensimbi ye-ductile, futhi ukusebenza kwayo kufanele kuqondwe ngokuningiliziwe lapho kukhethwa.
Izinzuzo kanye nokubi kwe ductile iron pipe
Ainzuzo
Amapayipi ensimbi asetshenziswayo asetshenziswa kumanethiwekhi amapayipi anomfutho ophakathi nophansi (ngokuvamile asetshenziswa ngaphansi kwe-6MPa).Amapayipi ensimbi asebenza ngokuphephile futhi anokwethenjelwa, izinga lokulimala eliphansi, ukwakhiwa nokugcinwa okusheshayo nokuhle, kanye nokumelana nokugqwala okuhle kakhulu.Ipayipi elisanda kwakhiwa lochungechunge lwe-“Yandun” lingasetshenziswa ekwakhiweni okungenazintambo futhi lisetshenziswe kabanzi ekwakhiweni kwamapayipi emifuleni, imigwaqo nezakhiwo.Ipayipi lochungechunge lwe-“Saizin” lisebenzisa inqubo ekhethekile yokufafaza ingxube ye-aluminium ye-zinc ukuze kuthuthukiswe ukumelana nokugqwala kwepayipi izikhathi eziningana, futhi lisetshenziswa kabanzi ekwakhiweni komhlabathi ogqwala kakhulu.
Dinzuzo
Ngokuvamile, ayisetshenziswa kunethiwekhi yamapayipi anomfutho ophezulu (ngaphezu kuka-6MPa).Ngenxa yokuthi umzimba wamapayipi unzima kakhulu, kufanele kusetshenziswe imishini ngesikhathi sokufakwa.Uma amanzi evuza ngemva kokuhlolwa komfutho, wonke amapayipi kufanele ambiwe, amapayipi kufanele aphakanyiswe phezulu lapho angafakwa khona ezinsimbini, futhi izinsimbi kufanele zifakwe ukuvimbela ukuvuza kwamanzi.
