Huahana Huahana
ʻO nā paipu hao hao ʻoʻoleʻa i ʻike ʻia hoʻi ʻo ka ductile iron a i ʻole nā paipu kila hao i loaʻa ka ikaika o ke kila a me ka paʻakikī o ka hao. Loaʻa ka Graphite ma ke ʻano spherical (nā papa 6 - 7) me kahi pae spheroidization o 1 - 3 a me ka helu ≥80%, hiki ke hoʻomaikaʻi i nā waiwai mechanical. Ma hope o ka hoʻomaʻamaʻa wela, ʻo ka microstructure ka nui o ka ferrite a me ka liʻiliʻi o ka pearlite, nona ke kūpaʻa maikaʻi a me ka hana kiʻekiʻe.

| 10. MOQ | 1 tona |
| 11. Hāʻawi: | Nā pūʻolo, i ka nui, |
1.Resistance i ka Puʻe Kuloko: He kiʻekiʻe ke kiʻekiʻe o ka hoʻolālā, a ʻoi aku ka nui o ka pahū ʻana i ʻekolu mau manawa o ke kaomi hana, hiki ke hōʻoia i ka palekana ʻoi aku ka maikaʻi ma mua o nā mea ʻē aʻe.
2.Resistance to External Pressure: ʻO ka ikaika kiʻekiʻe o ka paipu e hiki ai i kahi hoʻonohonoho pono a me ka hoʻokele waiwai, no ka mea ʻaʻole lākou e koi i kahi moena kūikawā a i ʻole nā lole pale.
3. Inner anti corrosion papa: Smooth, lōʻihi a me ka wai inu palekana Coating ciment lining wili ma ISO 4179.
4.Protective layer: Zinc spraying (≥130 g / m2, ISO 8179) a me ka pena resin chlorinated, hāʻawi i ka pale ʻana i ka corrosion. Loaʻa pū me ka papa zinc ʻoi aku ka mānoanoa a i ʻole me ka zinc-aluminum coating ma ke noi a nā mea kūʻai aku.
Nā hiʻohiʻona
ʻO nā paipu hao ductile, he ʻano paipu hao, hui pū i kaikaika o ke kilame kapaakiki o ka hao. Hoʻomalu ʻia ka spheroidization mapae 1–3(ka helu ≥80%) e hoʻonui i nā waiwai mechanical. ʻO nā paipu Annealed hiʻohiʻona aferrite matrix me ka pearlite liʻiliʻi, hāʻawi maikaʻi i ka corrosion kūpaʻa, ductility, sealing hana, a me ka maʻalahi hoʻokomo.
Hoʻokaʻawale ʻia ka nui o ka graphite nodular ma ka matrix ferrite a me ka pearlite. ʻO ka nui o ka ferrite a me ka pearlite i loko o ka hoʻolālā matrix e pili ana i ke anawaena nominal a me nā koi elongation. ʻO ka nui o ka pearlite i nā anawaena liʻiliʻi ʻaʻole iʻoi aku ma mua o 20%, ʻoiai ma nā anawaena nui e hoʻomalu ʻia ma kahi o 25%.
Palapala noi
He kūpono nā paipu hao ductile no ka wai inu (BS EN 545) a me nā ʻōnaehana sewerage (BS EN 598) me ke anawaena mai 80-1600 mm. He mea maʻalahi lākou e hui pū, hiki ke hoʻohana ʻia i nā kūlana o ke aniau, pinepine me ka ʻole o ka backfill kūikawā, a hāʻawi i kahi kumu palekana nui me ka hiki ke hoʻololi i ka neʻe ʻana o ka honua, no laila ua ʻōlelo ʻia lākou no nā hoʻohana pipeline like ʻole.

FAQ
-
Pehea e hiki ai iaʻu ke loaʻa kahi ʻōlelo?
E waiho iā mākou i kahi leka, a e pane koke mākou. -
E hoʻouna ʻoe i ka manawa?
ʻAe, hōʻoia mākou i nā huahana kiʻekiʻe a me ka hāʻawi manawa. ʻO ka ʻoiaʻiʻo ko mākou kumu kumu. -
Hiki iaʻu ke loaʻa nā laʻana ma mua o ke kauoha ʻana?
ʻAe, manuahi nā laʻana a hiki ke hana ʻia ma muli o kāu mau laʻana a i ʻole nā kiʻi ʻenehana. -
He aha kāu mau ʻōlelo uku?
ʻO ka maʻamau,30% waihome ke koena i ukuia no B/L. -
ʻAe ʻoe i ka nānā ʻana o nā ʻaoʻao ʻekolu?
ʻAe, ʻae piha mākou i ka nānā ʻana o nā ʻaoʻao ʻekolu. -
Pehea mākou e hilinaʻi ai i kāu hui?
Loaʻa iā mākou nā makahiki o ka ʻike ma ke ʻano he mea kūʻai gula ma ka ʻoihana kila. Aia ko mākou keʻena nui ma Tianjin, a mahalo mākou i ka hōʻoia a i ʻole ka hoʻokolokolo.
