ʻIkepili o ka Paipu Hao Ductile
ʻO nā paipu hao ductile he mau paipu i hana ʻia me ka hao ductile. He hao hoʻolei graphite spheroidized ka hao ductile. ʻO ke kiʻekiʻe o ka hilinaʻi o ka hao ductile ma muli o kona ikaika kiʻekiʻe, ke kūpaʻa, a me ke kūpaʻa i ka hopena a me ka pala. Hoʻohana pinepine ʻia nā paipu hao ductile no ka hoʻolaha ʻana i ka wai inu a me ka pamu ʻana i nā slurries, sewer a me nā kemika hana. ʻO kēia mau paipu hao he hoʻomohala pololei ia o nā paipu hao i hoʻolei mua ʻia i aneane pani ʻia. ʻO ke kiʻekiʻe o ka hilinaʻi o nā paipu hao ductile ma muli o kona mau waiwai maikaʻi like ʻole. ʻO kēia mau paipu nā paipu i ʻimi nui ʻia no kekahi mau noi.

ʻEkolu Papa Nui o ka Paipu Hao i Hoʻolei ʻia
Hao Hina V-2 (papa 40), Hao Ductile V-3 (65-45-12), a me ka Hao Ductile V-4 (80-55-06). Hāʻawi lākou i ka ikaika compression maikaʻi loa a me ka hiki ke hoʻēmi i ka haʻalulu kiʻekiʻe.
Hao hina V-2 (papa 40), ASTM B48:
Loaʻa i kēia papa ka ikaika tensile kiʻekiʻe o 40,000 PSI me ka ikaika compression o 150,000 PSI. Loaʻa kona paʻakikī mai 187 - 269 BHN. He kūpono loa ʻo V-2 no nā noi ʻaʻahu pololei a loaʻa iā ia ka ikaika kiʻekiʻe loa, ka paʻakikī, ke kū'ē ʻana i ke komo ʻana a me ka pane wela no ka hao hina unalloyed. Hoʻohana nui ʻia ia no nā noi bearing a me bushing i ka ʻoihana hydraulics.
V-3 (65-45-12) Hao Uʻuku, ASTM A536:
ʻO kēia papa he ikaika tensile o 65,000 PSI, ka ikaika hua o 45,000 PSI, me ka elongation 12%. Loaʻa ka paʻakikī mai 131-220 BHN. ʻO kona ʻano ferritic maikaʻi e hoʻolilo i ka V-3 i ka machining maʻalahi loa o nā papa hao ʻekolu e lilo ia i hoʻokahi o nā papa machiniability kiʻekiʻe o nā mea ferrous ʻē aʻe; i hui pū ʻia me ka hopena maikaʻi loa, ka luhi, ka conductivity uila a me nā waiwai permeability magnetic. Hoʻohana nui ʻia ka hao Ductile, ʻoiai nā paipu, no nā laina wai a me nā wai ʻino. Loaʻa pinepine ʻia kēia metala i nā ʻāpana kaʻa a me nā noi ʻoihana.
V-4 (80-55-06) Hao Uʻuku, ASTM A536:
ʻO ka ikaika tensile o kēia papa he 80,000 PSI, ka ikaika yield o 55,000 PSI a me ka elongation o 6%. ʻO ia ka ikaika kiʻekiʻe loa o nā papa ʻekolu, e like me ka hoʻolei ʻia. Hiki ke mālama ʻia kēia papa i ka wela i ka ikaika tensile 100,000 PSI. He 10-15% ka haʻahaʻa o ka helu machiniability ma mua o ka V-3 ma muli o kona ʻano pearlitic. ʻO ka mea pinepine ke koho ʻia i ka wā e pono ai nā kino kila.
ʻOi aku ka maikaʻi o nā paipu DI ma mua o nā paipu kila / PVC / HDPE
• Mālama pū nā DI Pipes i nā kumukūʻai hana ma nā ʻano he nui e pili ana i nā kumukūʻai pamu, nā kumukūʻai tapping, a me nā pōʻino hiki mai nā kūkulu ʻē aʻe, e hana ana i ka hāʻule ʻana a me ke kumukūʻai e hoʻoponopono ai ma ke ʻano laulā.
• ʻO ke kumukūʻai o ke ola o nā DI Pipes kekahi o kona mau pono nui loa. No ka mea he mau ia no nā hanauna, he waiwai hoʻokele waiwai ke hana, a maʻalahi a maikaʻi hoʻi ke kau ʻia a hoʻohana ʻia, ʻoi aku ka haʻahaʻa o kona kumukūʻai no ka wā lōʻihi a i ʻole ke ola ma mua o nā mea ʻē aʻe.
• He mea hana hou 100% ka paipu hao ductile ponoʻī.
• Ua lawa kona ikaika e kū i nā kūlana koʻikoʻi loa, mai nā noi kaomi kiʻekiʻe, a i nā ukana lepo kaumaha a me nā ukana kaʻa, a hiki i nā kūlana lepo paʻa ʻole.
• He maʻalahi a palekana ke kau ʻana no nā limahana e hiki ke ʻoki a hoʻopā i ka Paipu Hao Ductile ma kahi.
• ʻO ke ʻano metala o ka Ductile Iron Pipe ʻo ia hoʻi hiki ke loaʻa maʻalahi ka paipu ma lalo o ka honua me nā mea huli paipu maʻamau.
•Hāʻawi nā paipu DI i ka ikaika tensile kiʻekiʻe ma mua o ke kila palupalu a mālama i ke kūpaʻa corrosion kūlohelohe o ka hao i hoʻolei ʻia.
