Paipu hao nodular
Huahana Huahana
ʻO nā paipu hao hao nodular he mau paipu hao ductile, nona ke ʻano o ka hao a me nā waiwai o ke kila, no laila ko lākou inoa. ʻO ka graphite i loko o nā paipu hao ductile aia ma ke ʻano spherical, me ka nui maʻamau o 6-7 mau māka. Ma keʻano o ka maikaʻi, pono e hoʻomaluʻia ka pae spheroidization o nā paipu hao hao ma nā pae 1-3, me ka nui o ka spheroidization o ≥ 80%. No laila, ua hoʻomaikaʻi ʻia nā ʻano mechanical o ka mea ponoʻī, nona ke ʻano o ka hao a me nā waiwai o ke kila. Ma hope o ka annealing, ʻo ka microstructure o nā paipu hao ductile he ferrite me kahi liʻiliʻi o ka pearlite, nona nā waiwai mechanical maikaʻi, no laila ua kapa ʻia ʻo ia he paipu kila hao.

1. ʻO ka hana o ke kū'ē kū'ē i loko:
ʻO Centrifugal ductile iron ka mea nui o ka hao a me ka hana o ke kila, no laila ʻoi aku ka maikaʻi o nā paipu hao ductile ma mua o nā paipu i hana ʻia mai nā mea ʻē aʻe. ʻOi aku ka kiʻekiʻe o ke kaomi hana i hoʻolālā ʻia ma mua o nā paipu i hana ʻia mai nā mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o ke kumu palekana, a ʻo ka hiki ke pahū.
ʻekolu manawa o ke kaomi hana.
2. ʻO ka hana o ke kū'ē kū'ē i waho:
Hiki i ke kiʻekiʻe puʻe ke pale aku i ka pono o ka moena paipu a me ka uhi pale, e hana ana i nā paipu e hoʻomoe hou a hoʻokele waiwai.
3. Inner anti-corrosion papa:
ʻO ka ʻaoʻao o loko o nā paipu hao ductile i hoʻoheheʻe ʻia me ka mortar sima. Hoʻopili ka lining sima i ke kūlana honua ISO4179, e hōʻoiaʻiʻo ana i ka ikaika a me ka maʻalahi o ka mortar. ʻAʻole e hāʻule a ʻino paha ka uhi kaʻa, a ʻo kona mānoanoa e hōʻoiaʻiʻo ana i ka wai inu i lawe ʻia e nā paipu e loaʻa ka pale maikaʻi.
4. Ka uhi pale:
ʻO ka hoʻoheheʻe ʻana i ka zinc o nā paipu hao ductile hiki ke pale i nā paipu me ka ikaika ma o ka hopena electrochemical o ka zinc a me ka hao. Me ka pena resin chiorinated kiʻekiʻe, e hoʻonui ʻia nā paipu i ka pale anti-corrosion. ʻAʻole emi ka zinc ma luna o kēlā me kēia paipu ma mua o 130g/m², a hoʻokō me ka maʻamau ISO8179. Hiki iā mākou ke hoʻonui i ka mānoanoa zinc spraying a i ʻole spray zinc & aluminum alloy layer e like me ka koi o nā mea kūʻai.
Nā hiʻohiʻona
ʻO ka paipu hao ductile he ʻano paipu hao. Ma keʻano o ka maikaʻi, pono e hoʻomaluʻia ka pae spheroidization o nā paipu hao hao ma nā pae 1-3 (ka helu spheroidization> 80%), no laila e hoʻomaikaʻi ai i nā pono mechanical o ka mea pono'ī, nona keʻano o ka hao a me nā waiwai o ke kila. . ʻO ka paipu hao ductile annealed he ʻano metallographic o ka ferrite me ka liʻiliʻi o ka pearlite, nona nā waiwai mechanical maikaʻi, maikaʻi anti-corrosion hana, ductility maikaʻi, hopena sealing maikaʻi, hoʻokomo maʻalahi, a hoʻohana nui ʻia no ka hoʻolako wai, lawe kinoea. , kaʻaila hinu, a me nā mea'ē aʻe ma nāʻoihana kaona a me nāʻoihanaʻoihana.
Aia kekahi nui o ka graphite spherical i puunaueia ma ka matrix o ka ferrite a me ka pearlite. Ma muli o ke anawaena nominal a me nā koi no ka elongation, ʻokoʻa ka hapa o ka ferrite a me ka pearlite i ka hoʻolālā matrix. ʻAʻole ʻoi aku ka nui o ka pearlite ma nā anawaena liʻiliʻi ma mua o 20%, ʻoiai ʻo ka nui o nā anawaena nui e hoʻomalu ʻia ma kahi o 25%.
Palapala noi
Loaʻa nā paipu hao Ductile i nā anawaena mai 80mm a 1600mm a ua kūpono no ka lawe ʻana a me ka hāʻawi ʻana i ka wai inu (e like me BS EN 545) a me ka sewerage (e like me BS EN 598). , hiki ke waiho ʻia i loko o nā kūlana ania a pau a pinepine ʻole me ka pono ʻole o ka hoʻihoʻi i koho ʻia. ʻO kāna kumu palekana kiʻekiʻe a me ka hiki ke hoʻokipa i ka neʻe ʻana o ka honua e lilo ia i mea pipeline kūpono no ka nui o nā noi.
