Ductile Iron Pipe vs Cast Iron Pipe: Misiyano mikuru mitanhatu uye maitiro ekusarudza

Simbi ine ductile yakasimba, inopetwa uye yakavakirwa pamitsetse ine pressure; simbi yakaumbwa yakasimba, inodhura zvishoma uye yakavakirwa pakuburitsa mvura inokwevera pasi. Sarudza zvichibva pakumanikidzwa, kwete pamutengo.Mapaipi ese ari maviri iron-carbon alloys uye, kubva kure, anotaridzika akafanana - asi akagadzirwa kuti ashande mabasa akasiyana. Ductile iron inodzivirira kumanikidzwa, kurovera uye kufamba kwevhu. Ductile iron inoramba yakasimba uye isingadhuri mumagetsi anokwevera pasi. Sarudza zvisiri izvo uye unosangana nekudonha kwemvura, kutsiva nekukurumidza kana kutambisa mari. DINSEN inogadziramasisitimu emvura yesimbi yakakandwa yegreykusvika kuEN 877 / ASTM A888 uyemapaipi esimbi ane ductilekusvika kuEN 545 / ISO 2531, saka tinoona mubvunzo kubva kumativi ese efoundry.

1. Magadzirirwo eGraphite: Panotangira Zvese

Musiyano chaiwo uripo pasi pe microscope. Iron ine grey cast simbigirafiti yeganda; simbi ine ductile inegirafiti ine spheroidalzvinogadzirwa nekuwedzera magnesium panguva yekukanda. Maflakes anoita semaburi emukati - kushushikana kunowedzera pamipendero yawo uye simbi inogona kukundikana kamwe kamwe. Mabhora anomisa maburi kuti asapararire, saka simbi inokotama panzvimbo pekutyoka. Ichi chimwe chinhu chinotsanangura musiyano wese uri pazasi.

2. Simba uye Kugona Kushanda

Ductile iron inopaSimba rekudhonza re ≥ 420 MPanepedyokureba kwe10%, zvichienzaniswa ne150–250 MPa uye pasi pe1% yesimbi yakakandwa yegrey. Muvhu mukaha iwoyo unosarudza kurarama: simbi yakakandwa inonwisa mvura, kumanikidzwa kwemvura uye kugadzikana kwevhu izvo zvinogona kupwanya simbi yakakandwa. Mukuita kwemumunda, pombi yakakandwa inogonawo kutsauswa kana kukotama pamajoini pasina kukanganisa, izvo zvinoita kuti kurongeka kwesimbi mumigero isina kuenzana kuve nyore. Kana tambo yako iine kumanikidzwa, simbi yakakandwa ndiyo mhinduro yeinjiniya.

3. Maitiro uye Kuyera Kumanikidzwa

Maitiro anoratidza basa raunoda kuita. Kuyerera kwesimbi yakakandwa mugrey kunotevera EN 877 kana ASTM A888 uye kunokodzera masisitimu egiravhiti, asiri ekumanikidza akadai sekuvaka DWV uye sewer laterals. Ductile iron inotevera ISO 2531, EN 545, EN 598 (sewage) kana AWWA C151 uye inoongororwa mumakirasi ekumanikidza K9, K10 neK12 — K9 ​​ndiyo inonyanya kushandiswa pamapaipi emvura. Kana zvakataurwa zvichitaura nezvekirasi yekumanikidza, uri kutarisa ductile iron.

4. Majoini uye Kuiswa

Majoini anoratidza kupatsanurwa kwakafanana. Ductile iron inoshandisa majoini erabha-gasket anosundidzira oga pasi pekumanikidzwa uye anoiswa nekukurumidza, aine nzira dzemakanika, dzakapinza uye dzakadzorwa kuti dzishande mumamiriro ezvinhu akaoma. Kuyerera kwemvura kwesimbi yakakandwa kunoenderana nekubatanidza kusina hub kana majoini ehub-and-spigot, anokurumidza kuungana muzvikamu zvakamira. Ose anoshanda panzvimbo yacho; musiyano ndewekuti majoini eductile akagadzirwa kuti agone kuchengetedza kumanikidzwa, uye mhando yega yega inoedzwa kune imwe nzira yakasiyana.

5. Kudzivirirwa Kwengura uye Hupenyu Hwebasa

Mapaipi ese ari maviri akafukidzwa nejira rekunze rezinc pamwe nebhitumini uye simende yemukati ine simbi inobvumirwa kushandiswa mumvura inonwiwa; yakaiswa nemazvo, hupenyu hwekushanda hunosvika makore 50-100. Kuyerera kwemvura musimbi inogadzirwa nesimbi inoshandisa enamel, epoxy kana bitumen coatings yakakodzera mvura yakasviba. Hunhu hwekufukidza hunosarudza hupenyu hwezuva nezuva, chimwe chikonzero chekutenga kubva kumugadziri ane kugadzirwa kwakarongwa.

6. Mutengo uye Kukosha Kwese

Simbi yegrey yakakandwa yakachipa pamita imwe chete, uye izvozvo ndizvo chaizvo zvine chekuita nemari: kudhonza mvura hakudi zvinhu zvine simba rekumanikidza. Simbi yeductile inodhura zvakanyanya pakutanga asi inogona kukunda pamutengo wese wekuva muridzi wayo kuburikidza nekukundikana kwakaderera uye mitengo yekugadzirisa mumabasa ane simba rekumanikidza. Usamboenzanisa mutengo wega - enzanisa zvinofanira kuitwa nepombi, paichagara, uye kwenguva yakareba sei.

Maitiro Ekusarudza: Rondedzero Inoshanda

• Mutsetse wakamanikidzwa(mugero wemvura, tsvina inomanikidzwa, mugero wemoto)? → Simbi yemuchina wepurasitiki

• Kudhonza mvura inokwevera pasi kana DWV yekuvaka?→ Simbi yegrey yakakandwa pa EN 877 / ASTM A888

• Kubata mvura inonwiwa here?→ Simbi yepurasitiki ine simende yemukati

• Ivhu rakaoma, kuvigwa kwakadzika kana kuti kusina mugero?→ Simbi yesimbi

• Spec inotaura nezvekirasi yekumanikidzwa?→ Simbi yesimbi

Mibvunzo Inowanzo bvunzwa

1. Pombi yesimbi inogona kushandiswa here pamvura ine pressure?

Kwete. Simbi yegrey haina chiyero chakatsanangurwa chekumanikidzwa kwemvura; simbi ye ductile ndiyo sarudzo inoenderana nekumanikidzwa.

2. Pombi yesimbi inopinza inodhura kupfuura simbi yakakandwa here?

Pamita imwe neimwe, kazhinji hongu. Pamakore gumi ekushanda pasi pekumanikidzwa, simbi inoyerera kazhinji inodhura zvishoma nekuti kukundikana nekugadzirisa hazviwanzoitiki.

3. Zvinorevei K9?

K9 ikirasi yemadziro akakora yakatsanangurwa muISO 2531 / EN 545 — ndiyo inonyanya kushandiswa pamapombi emvura. K10 neK12 zvinopa madziro akakora ekuderedza kumanikidzwa kwakanyanya.

4. Iron ine ductile inogona kushandiswa here pakuburitsa mvura?

Ehe. EN 598 inovhara simbi inoyerera mutsvina. Simbi yegrey cast paEN 877 inoramba iri sarudzo inodhura pakugadzira madhiraivha emvura nezvimwe zvinoshandiswa pakukwevera pasi.

5. Ko mhando mbiri dzemapaipi dzinochinjika here?

Kwete zvakananga. Vanoshandisa majoini akasiyana, zviyero uye kumanikidzwa kwakasiyana, saka chinotsiva chinofanira kuenderana nekugadzirwa kwesystem yekutanga.
