Nānā o nā Paipu Hao Ductile
Ua ʻoi aku ma mua o 70 mau makahiki mai ka wā i hana ʻia ai ka paipu hao ductile i nā makahiki 1940. Me kona ikaika kiʻekiʻe, kiʻekiʻe elongation, corrosion resistance, kū'ē i ka haʻalulu, hana maʻalahi a me nā hiʻohiʻona maikaʻi ʻē aʻe he nui, ʻo ka paipu hao ductile ka koho maikaʻi loa i kēia ao no ka lawe ʻana i ka wai a me ke kinoea me ka palekana. ʻO ka hao Ductile, i kapa ʻia hoʻi ka hao nodular a i ʻole ka hao graphite spheroidal, ua ʻike ʻia e ka loaʻa ʻana o ka graphite spheroidal i nā hoʻoheheʻe hopena.

Na Kii o na Paipu Hao Ductile
Loaʻa nā paipu hao ductile i nā anawaena mai 80 mm a 2000 mm a kūpono no ka lawe ʻana a me ka hāʻawi ʻana i ka wai wai (e like me BS EN 545) a me ka sewerage (e like me BS EN 598). He mea maʻalahi ka hui ʻana o nā paipu hao ductile, hiki ke hoʻomoe ʻia i nā kūlana o ka wā a me ka pinepine ʻole me ka pono ʻole o ka backfill 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.
Nā Papa o ka Paipu Hao Ductile Hiki iā mākou ke hoʻolako
Hōʻike ka papa ma lalo nei i nā māka mea hao ductile no kēlā me kēia ʻāina.If he ʻAmelika ʻoe, a laila hiki iā ʻoe ke koho i ka 60-40-18, 65-45-12, 70-50-05 etc., inā no Australia ʻoe, a laila hiki iā ʻoe ke koho i ka 400-12, 500-7, 600-3 etc.

Na Hoohana Hao Ductile
ʻOi aku ka ikaika a me ka ductility ma mua o ka hao hina. ʻO kēlā mau waiwai e ʻae iā ia e hoʻohana maikaʻi ʻia i nā ʻano hana ʻoihana like ʻole, me ka paipu, nā ʻāpana kaʻa, nā huila, nā pahu pahu, nā hale pahū, nā papa mīkini no ka ʻoihana makani makani, a me nā mea hou aku. No ka mea, ʻaʻole ia e haki e like me ka hao hina, palekana ka hao ductile i ka hoʻohana ʻana i nā noi pale i ka hopena, e like me nā bollards.
