Kuenzanisa Kuedza Kutetepa kweDuctile Iron Pipe neSML Pipes Zvichienderana neEN10002-1

Kuyedza zvinhu zvesimbi zvine simba rekudhonza ndiyo nzira huru yekuongorora hunhu hwazvo hwemuchina uye kwakakosha zvikuru. Nekuyera maparamita akadai sekusimba kwekudhonza, simba rekugonza, uye kureba, zvinoyera kugona kwechinhu ichi kutakura mutoro uye hunhu hwekudhonza kwepurasitiki. Zvinopa hwaro hwekuchengetedza hwekugadzira mainjiniya uye zvinovimbisa kuvimbika kwechimiro. Zvinoshandawo sechishandiso chakakosha chekudzora hunhu, zvichisimbisa kugadzikana kwemaitiro ekugadzira uye kuona kuti zvinoenderana nemitemo yepasi rose. Uyezve, zvinogona kufanotaura njodzi yekukundikana kwezvinhu pasi pemitoro yakaoma uye kupa rutsigiro rwakakosha rwekugadzira zvinhu zvitsva.

Zvinotevera kuenzanisa nzira dzekuyedza tensile dzemapaipi esimbi ane ductileuyeMapaipi eSML, zvese izvi zvinobatsira kuona kuti chigadzirwa chacho chakanaka uye chinoshandiswa kwenguva refu mumamiriro ezvinhu akasiyana-siyana chaiwo.

1. Mienzaniso yeMhinduro
Ukobvu uye dhayamita yetsvimbo yekuyedza yemasampuli esimbi ane ductile ndeiyi inotevera:

Cherechedza: Bhara rekuyedza rakagadzirwa kubva mumuenzaniso wakagadzirwa, zvichimiririra simbi iri pakati peukobvu hwemuenzaniso. Rine chikamu chesilinda. Dhayamita yesilinda inoratidzwa mutafura iri pamusoro. Hurefu hwebhara rekuyedza hunopfuura kashanu dhayamita yaro. Mugumo webhara rekuyedza unofanirwa kukodzera kuiswa muchina wekuyedza. Kuomarara kwenzvimbo yesilinda yebhara rekuyedza iRz ≤ 6.3.

Pombi yeSML yakagadzirwa nesimbi yakakandwa yegrey uye muenzaniso wayo unofanirwa kuenderana nemufananidzo unotevera:

Cherechedza: Kuti uwane mhedzisiro yebvunzo inomiririra chigadzirwa chapera sezvinobvira, sampuli yebvunzo inofanira kutorwa kubva papombi yeSML kana SML fitting yochekwa yakaenzana ne axis yechubhu kana fitting. Nzvimbo yekutanga yechikamu chemuenzaniso inofanira kuyerwa. Upamhi neukobvu hwechikamu chemuchinjikwa zvinofanirwa kuyerwa nemazvo kusvika 0.1mm usati waedzwa.

2. Misiyano mumaitiro ebvunzo

Kunyangwe bvunzo dzese dzekudhonza dzichiitwa uchishandisa muchina wekuyedza kudhonza universal, zvishandiso zvinoshandiswa zvakasiyana.Chishandiso chekuyedza tambo yesimbi ine ductile chinoratidzwa pazasi:

Pombi yeSML uye chigadziko chekuyedza chekunamira zvinoratidzwa pazasi:

3. Musiyano uripo pakati peMhedzisiro yeBvunzo neZvinhu zveChinhu
Maitiro ekunyungudutsa nekugadzira simbi ine ductile imhaka yemakore akawanda ekuunganidza tekinoroji uye kushanda nesimba. Kambani yedu inogadzira mapaipi esimbi ane ductile emhando yepamusoro, ane mwero we spheroidization we90% kana kupfuura. Kuyedzwa kwe tensile kunoratidza simba rekudhonza riri pakati pe460MPa ne490MPa, uye kureba kuri pakati pe10% ne17%. Zvichienderana neEN545 neISO2531 standards, simba rekudhonza re420MPa kana kupfuura uye kureba kwe5% kusvika 10% kana kupfuura zvinoonekwa sezvinogamuchirwa. Simba rekudhonza rakajairwa uye kureba ndeizvi:

Mapaipi eSML nemidziyo yekubatanidza zvinhu zvakagadzirwa nesimbi yakacheneruka. Chimiro chegrafiti chakacheneruka mukati mesimbi yakacheneruka chinotora kudengenyeka kwemvura, zvichikonzera ruzha rwemvura rwuri pasi pe10dB pane mapaipi ePVC. Anopawo simba rekudzivirira kupisa kwepamusoro-soro, rinodarika 1,000°C. Mhete dzerabha dzinovhara dzinoramba dzichishanda kunyangwe pa70°C inoenderera mberi kana 120°C inobuda nguva nenguva, nekushanduka kwekupisa kwemvura chikamu chimwe chete pazvikamu zvishanu pane mapaipi ePVC. Anopawo simba rekusimba, rekudzivirira kukuvadzwa, uye rekudzivirira kukwesha, kanenge kashanu pane mapaipi ePVC.

Zvichienderana neEN877 standard, hunhu hwemakanika hwemapaipi eSML ne fittings ndeinotevera:

Mapaipi eSML nezvigadziko, mapaipi ePVC, bvunzo yekudhonza yeSML yeEN877, kudhonza kweSML, mapaipi esimbi eductile eEN545 ISO2531 nemapaipi eSML, sampuro dzesimbi dzeductile, mapaipi eSML, mapaipi esimbi egrey cast,
