Pfupiso yeDuctile Iron Pipe
Mapaipi esimbi akagadzirwa nesimbi yakapfava. Simbi yakapfava isimbi yakapfava ine girafiti. Kugona kwayo kupfava kwakanyanya kunokonzerwa nekusimba kwayo, kugara kwenguva refu, uye kuramba kwayo kudonha. Mapaipi esimbi anowanzo shandiswa pakugovera mvura inonwiwa uye kupomba slurry, tsvina uye makemikari ekugadzira. Mapaipi aya esimbi akagadzirwa zvakananga nemapaipi esimbi akapfava ekare ayo yava kuda kutsiva. Kugona kwayo kupfava kwakanyanya nekuda kwehunhu hwayo hwakanaka. Mapaipi aya ndiwo anonyanya kutsvagwa pakushandiswa kwakawanda.

Matatu Makuru Matatu eCasted Iron Pipe
V-2 (kirasi 40) Iron yeGrey, V-3 (65-45-12) Iron yeDuctile, uye V-4 (80-55-06) Iron yeDuctile. Dzinopa simba rakanaka rekudzvanya uye kugona kwakanyanya kudzima vibration.
V-2 (kirasi 40) Iron yeGrey, ASTM B48:
Chiyero ichi chine simba guru rekudhonza re40,000 PSI uye simba rekudzvanya re150,000 PSI. Kuoma kwayo kunobva pa187 - 269 BHN. V-2 yakakodzera kushandiswa pakupfeka zvakananga uye ine simba guru, kuomarara, kuramba kupfeka uye kupisa kwesimbi isina grey. Inoshandiswa zvakanyanya pakushandisa mabheyaringi uye bushing muindasitiri yehydraulics.
V-3 (65-45-12) Ductile Iron, ASTM A536:
Giredhi iyi ine simba rekudhonza re65,000 PSI, simba rekupa re45,000 PSI, ine kureba kwe12%. Kuoma kwayo kunobva pa131-220 BHN. Chimiro chayo cheferritic chakanaka chinoita kuti V-3 ive nyore kushandisa pane mamwe magiredhi matatu esimbi zvichiita kuti ive imwe yemagiredhi epamusoro ekugadzira michina kupfuura mamwe masimbi; kunyanya pamwe chete nemhedzisiro yakanaka, kuneta, kufambisa magetsi uye kugona kwemagetsi kupinda. Ductile Iron, kunyanya mapaipi, inonyanya kushandiswa pamigero yemvura netsvina. Simbi iyi inowanikwawo muzvikamu zvemotokari uye mumaindasitiri.
V-4 (80-55-06) Ductile Iron, ASTM A536:
Giredhi iyi ine simba rekudhonza re80,000 PSI, simba rekupa 55,000 PSI uye kureba kwe6%. Ndiyo simba guru pane ese matatu, seyakaumbwa. Giredhi iyi inogona kugadziriswa nekupisa kusvika ku100,000 PSI tensile strength. Ine chiyero chepasi che10-15% chemachiniability kupfuura V-3 nekuda kwechimiro chayo chepearlitic. Inowanzo sarudzwa kana paine simbi physicals dzinodiwa.
Mapaipi eDI ari nani pane mapaipi esimbi / PVC / HDPE
• Mapaipi eDI anochengetedzawo mari yekushandisa nenzira dzakasiyana siyana dzinosanganisira mari yekupomba, mari yekupomba, uye kukuvara kunogona kuitika kubva kune dzimwe nzvimbo dzekuvaka, zvichikonzera kutadza uye mari yekugadzirisa zvakazara.
• Mari yekushanda kweDI Pipes kwenguva refu ndeimwe yezvakanakira zvikuru. Sezvo ichigara kwenguva refu, isingadhuri kushanda, uye ichiiswa uye ichishandiswa zviri nyore uye zvinobudirira, mutengo wayo wenguva refu kana wehupenyu hwese wakaderera zviri nyore kupfuura chero chimwe chinhu.
• Pombi yesimbi inogadziriswa pachayo inogona kushandiswazve zvizere.
• Yakasimba zvakakwana kuti ikwanise kutsungirira mamiriro akaomarara, kubva pakushandiswa kwesimba rakawanda, kusvika kuvhu rakawanda uye kutakura zvinhu, kusvika kumamiriro evhu asina kugadzikana.
• Kuisa kwacho kuri nyore uye kwakachengeteka kune vashandi vanogona kucheka nekubaya Ductile Iron Pipe panzvimbo yacho.
• Hunhu hwesimbi hweDuctile Iron Pipe hunoreva kuti pombi inogona kuwanikwa zviri nyore pasi pevhu nemidziyo yemazuva ano yekutsvaga pombi.
•Mapaipi eDI ane simba rekusimba kupfuura simbi isina kusimba uye anoramba achidzivirira ngura sesimbi yakakandwa.
