Mhedziso yeDuctile Iron Pipe
Ductile Iron pombi mapaipi akagadzirwa ne ductile iron. Ductile iron is spheroidized graphite cast iron. Iyo yakakwirira dhigirii yekuvimbika kweiyo ductile iron inonyanya kukonzerwa nekusimba kwayo kwepamusoro, kusimba, uye kukanganisa uye kushomeka kwemarara. Ductile iron pombi dzinowanzo shandiswa pakugovera mvura inonwiwa uye kupomba kweslurries, suweji uye kugadzira makemikari. Mapombi esimbi aya kugadzirwa kwakananga kwepombi dzesimbi dzakakandwa dzave kuda kutsiva. Iyo yakakwirira yekuvimbika kweiyo ductile iron mapaipi imhaka yemhando dzakasiyana dzepamusoro. Mapombi aya ndiwo anonyanya kutsvakwa pombi kune akati wandei.

Magiredhi Matatu Makuru eCasted Iron Pipe
V-2 (kirasi 40) Grey Iron, V-3 (65-45-12) Ductile Iron, uye V-4 (80-55-06) Ductile Iron. Ivo vanopa yakanakisa compression simba uye yakakwirira vibration dampening kugona.
V-2 (kirasi 40) Grey Iron, ASTM B48:
Giredhi iri rine simba repamusoro re40,000 PSI rine simba rekumanikidza re150,000 PSI. Kuoma kwayo kunobva pa187 - 269 BHN. V-2 yakanyatsokodzera kutwasaruka maapplication uye ine yakanyanya simba, kuoma, kuramba kupfeka uye kupisa kwekubata mhinduro kune isina kusanganiswa grey iron. Inoshandiswa zvakanyanya kubereka uye bushing application muindasitiri ye hydraulics.
V-3 (65-45-12) Ductile Iron, ASTM A536:
Iri giredhi rine simba rekusimba re65,000 PSI, goho simba re45,000 PSI, ine 12% kureba. Kuomarara kunobva pa131-220 BHN. Chimiro chayo chakanaka cheferritic chinoita kuti V-3 ive yakapusa machining pamagiredhi matatu esimbi zvichiita kuti ive imwe yemhando yepamusoro yemagiredhi yakayerwa magiredhi ezvimwe zvinhu zvine ferrous; yakanyatso kusanganiswa neyakakwana kukanganisa, kuneta, magetsi conductivity uye magineti permeability zvimiro. Ductile Iron, kunyanya pombi, inonyanya kushandiswa kumvura uye mitsetse yetsvina. Iyi simbi inowanikwawo muzvikamu zvemotokari uye maindasitiri ekushandisa.
V-4 (80-55-06) Ductile Iron, ASTM A536:
Giredhi iri rine simba rekusimba re80,000 PSI, goho resimba re55,000 PSI uye kurebesa kwe6%. Ndiro simba repamusoro-soro remagiredhi matatu, sekukanda. Iri giredhi rinogona kurapwa kupisa kusvika ku100,000 PSI tensile simba. Iyo ine 10-15% yakaderera machiniability rating pane iyo V-3 nekuda kweiyo pearlitic chimiro. Inonyanya kusarudzwa kana simbi yesimbi inodiwa.
DI Mapaipi ari nani pane simbi / PVC / HDPE mapaipi
• DI Mapaipi anochengetedzawo mari yekushandisa munzira dzinoverengeka dzinosanganisira mutengo wekupomba, mutengo wekutapa, uye kukuvara kunobvira kubva kune kumwe kuvaka, zvichikonzera kutadza uye mutengo wekugadzirisa zvakazara.
• Lifecycle mitengo yeDI Pipes ndeimwe yemabhenefiti ayo makuru. Sezvo inogara kwezvizvarwa, ine hupfumi kushanda, uye nyore uye zvinogoneka kuiswa uye kushanda, yayo yenguva refu kana yehupenyu mutengo inodzikira nyore pane chero zvimwe zvinhu.
• Ductile iron pipe pachayo ndeye 100% inogona kushandiswa zvakare.
• Yakasimba zvakakwana kuti igadzirise mamiriro ezvinhu akaoma zvikuru, kubva pakushandiswa kwepamusoro-soro, kusvika kune inorema pasi uye mitoro yemotokari, kune ivhu risina kugadzikana.
• Kuiswa kuri nyore uye kwakachengeteka kune vashandi vanogona kucheka nekubaya Ductile Iron Pipe panzvimbo.
• Hunhu hwesimbi hweDuctile Iron Pipe zvinoreva kuti pombi inogona kuwanikwa zviri nyore pasi pevhu paine mapombi akajairwa.
•DI mapaipi anopa yakakwira tensile simba kupfuura simbi yakapfava uye inochengeta iyo yekuzvarwa corrosion kuramba kwesimbi yakakandwa.
