A15 Hoʻoheheʻe ʻia i ka uhi a me ka pā
Hōʻike huahana
Nā uhi manhole hao ductileʻo ia kekahi ʻano o nā huahana hao ductile.Ua loaʻa i ka ductile iron ka graphite Spheroidal ma o ka pōleʻa a me ka bred deal, kahi e hoʻomaikaʻi maikaʻi ai i nā waiwai mechanical o ka hao hao, ʻoi aku ka hoʻomaikaʻi ʻana i ka ductility a me ka paʻakikī, e hopena i ka ikaika kiʻekiʻe ma mua o ke kila kalapona.Ua hoʻomohala ʻia ka hao ductile i mea hao hao ikaika loa i nā makahiki 1950.ʻO kāna hana holoʻokoʻa kokoke i ke kila.Ma muli o kāna hana maikaʻi loa, ua hoʻohana maikaʻi ʻia ka Ductile iron e hoʻolei i kekahi o ka ikaika paʻakikī, ikaika, paʻakikī, ʻaʻahu pono i nā ʻāpana kiʻekiʻe.ʻO ka hao ductile ka mea ma hope o ka ulu wikiwiki ʻana o ka hao hina hina i hoʻohana nui ʻia.ʻO ka mea i kapa ʻia "Hoʻololi i ke kila me ka hao", e pili ana i ka ductile iron.
NA PONO o na U'i MANHOLE 'DUCTILE IRON', PA'I & NUI:
- ʻO ka ikaika kiʻekiʻe, nā hopena i ke ola a me ka lōʻihi
- Loaʻa me ka Elegant Checkers Design, hāʻawi i ka Anti-skid Grip maikaʻi a me ka nani.
- Ma muli o kona ʻano hinge, ʻoi aku ka liʻiliʻi o nā manawa o ka ʻaihue.
- He kūpono no ka hoʻouka ʻana i nā kaʻa kaumaha a me ka wikiwiki kiʻekiʻe.
- Aneane e hoemiia na manawa o na ulia, no ka mea, aole nahaha koke.
- Ma muli o ka ikaika kiʻekiʻe, ʻo ka 'Ductile Iron' e hōʻemi i ka pilikia o ka hāʻule ʻana i ka wā hoʻohana maʻamau a hāʻawi i ka Resistance to Impact.
- Hiki i ka Ductile Iron's High Strength to Weight ratio hiki i nā mea hana ke hana i nā mea hoʻoheheʻe māmā māmā, e hāʻawi ana i ka 50% Weight Savings ma luna o ka Gray Iron Castings, a laila mālama i ke kumukūʻai no kēlā me kēia ʻāpana.
- Hāʻawi ʻo Lightweight Castings i nā pōmaikaʻi kumukūʻai, mai ka lawe ʻana i ka hoʻokomo ʻana, e hāʻawi ana i ka maʻalahi o ka lawelawe ʻana a me ka mālama ʻana i ka wā lawelawe.
