Nodular cast iron pipe
Product Detail
Nodular cast iron simbi mapaipi akanyanya ductile iron mapaipi, ayo ane musimboti wesimbi uye zvimiro zvesimbi, nekudaro zita rawo.Graphite mu ductile iron mapaipi iripo mune yakatenderera fomu, ine hukuru hwese hwemagiredhi 6-7.Panyaya yemhando, iyo spheroidization level ye cast iron pombi inodiwa kuti idzorerwe pa 1-3 mazinga, ine spheroidization rate ye ≥ 80%.Nokudaro, iyo mechanical properties yezvinyorwa pachayo yakagadziridzwa, iine essence yesimbi uye zvinhu zvesimbi.Mushure mekuvhara, iyo microstructure ye ductile iron mapaipi ndeye ferrite ine shoma shoma ye pearlite, iyo ine yakanaka yemagetsi maitiro, saka inonziwo cast iron iron pipes.

1.Kuitwa kwekupikiswa kwemukati:
Centrifugal ductile iron ine musimboti wesimbi uye kushanda kwesimbi, saka mapaipi esimbi anodhinda ane kuchengetedzwa kwakanaka kupfuura mapaipi anogadzirwa kubva kune zvimwe zvinhu.Iyo yakagadzirirwa kushanda kumanikidza yakakwira zvakanyanya kupfuura iyo yepombi dzakagadzirwa kubva kune zvimwe zvinhu, iyo safty factor yakakwira zvakanyanya, uye iyo inogona kuputika kumanikidza ndeye.
katatu kwesimba rekushanda.
2.Kuitwa kwekunze kwekumanikidza kuramba:
Iyo yakanyanya kudzvinyirira kuramba inogona kudzivirira kudiwa kwemubhedha wepombi uye chivharo chekudzivirira, zvichiita kuti mapaipi anoisa rellable uye ehupfumi.
3.Inner anti-corrosion layer:
Iyo yemukati yemukati ye ductile iron pombi inopfapfaidzwa nepakati nesamende dhaka.Cement lining inowirirana neInternational standard ISO4179, kuve nechokwadi chekuti dhaka rakasimba uye rakatsetseka.Iyo mota yekuputira haizodonha kana kusvibiswa, uye ukobvu hwayo huri kutoona kuti mvura yekunwa inotamiswa nemapombi inowana dziviriro yakanaka.
4.Protective coating:
Kupfapfaidza zingi kwepombi dzesimbi dzesimbi kwaigona kudzivirira mapaipi zvine simba kuburikidza ne electrochemical effect ye zinc ne iron.Iine yakakwira chiorinated resin pendi, mapaipi anozowana yakawedzera anti-corrosion dziviriro.Kupfapfaidza zingi kwepombi yega yega hakusi pasi pe130g/m², uye kunoenderana neISO8179 standard.Isu tinogona zvakare kuwedzera zinc yekupfapfaidza ukobvu kana kupfapfaidza zinc & aluminium alloy layer zvinoenderana nezvinodiwa nevatengi.
Features
Ductile iron pipe imhando yepombi yesimbi yakakandwa.Panyaya yemhando, iyo spheroidization level ye cast iron pombi inodiwa kuti idzorwe pa1-3 mazinga (spheroidization rate> 80%), nekudaro kuvandudza ma mechanic properties echinhu chacho, iine essence yesimbi uye zvinhu zvesimbi. .Iyo annealed ductile iron pombi ine metallographic chimiro cheferrite ine shoma shoma yepearlite, ine yakanaka michina zvivakwa, yakanakisa anti-corrosion performance, yakanaka ductility, yakanaka yekuisa chisimbiso, kuisirwa nyore, uye inonyanya kushandiswa kugovera mvura, kutapurirana gasi. , kutakurwa kwemafuta, nezvimwewo mumakambani emanisipala nemaindasitiri.
Pane imwe chiyero che spherical graphite yakagoverwa pane matrix ye ferrite uye pearlite.Zvichienderana nedhayamita yezita uye zvinodiwa pakurebesa, chikamu cheferrite uye pearlite mune matrix chimiro chinosiyana.Chikamu chepearlite mumadhayamita madiki kazhinji hachipfuuri 20%, nepo mumadhayamita akakura kazhinji anodzorwa paanenge 25%.
Application
Ductile iron pombi dzinowanikwa muhupamhi hwemadhayamita kubva pa80mm kusvika 1600mm uye dzakakodzera zvose zviri zviviri kutapurirana nekuparadzira mvura inonwiwa (maererano neBS EN 545) uye pombi yesuweji (maererano neBS EN 598). Ductile iron pombi dziri nyore kubatana. , inogona kuiswa mumamiriro ese emamiriro ekunze uye kazhinji pasina kudiwa kwekudzoserwa kwakasarudzwa.Yayo yakakwirira yekuchengetedza chinhu uye kugona kugadzirisa kufamba kwepasi kunoita kuti ive yakanakira pombi zvinhu zvemhando dzakasiyana dzekushandisa.
