Nūhou - He aha nā ʻokoʻa ma waena o nā paipu hao ductile a me nā paipu hao maʻamau?

Nui nā ʻokoʻa ma waenaPaipu Hao Ductiles a me nā mea hoʻolei maʻamauPaipu Haos e pili ana i ka waiwai, ka hana, ke kaʻina hana, ka helehelena, nā hiʻohiʻona noi a me ke kumukūʻai, penei:

Mea waiwai
Paipu hao ductile: ʻO ka mea nui he hao ductile. Ma ke kumu o ka hao hoʻoheheʻe maʻamau, hoʻohui ʻia ka spheroidizer a me ka inoculant e hoʻololi i ka graphite i ka hao hao mai ka flake a spherical.
Paipu hao maʻamau: He hao maʻamau ka mea, a ua puʻunaue ʻia kāna graphite i nā ʻōpala.

hana
Ka ikaika a me ka paʻakikī: ʻOi aku ka kiʻekiʻe o ka ikaika tensile a me ka paʻakikī o nā paipu hao ductile ma mua o nā paipu hao maʻamau. ʻO ka ikaika tensile o nā paipu hao ductile hiki ke piʻi i ka 400-900MPa, aʻo ka ikaika tensile o nā paipu hao maʻamau he 150-300MPa. ʻO nā paipu hao ductile maikaʻi ka hopena o ka hopena, ʻaʻole maʻalahi i ka haki ʻana, a hiki ke kū i nā ikaika o waho a me nā deformations.
ʻO ke kūpaʻa ʻino: Loaʻa iā lāua ʻelua ke ʻano o ka pale ʻana i ka corrosion, akā ʻoi aku ka paʻa o nā paipu hao ductile i ka corrosion ma muli o ko lākou ʻano ʻoi aku ka ʻoi aku ka nui o ka mālama anti-corrosion, e like me ka uhi zinc ma nā paia o loko a me waho, pena asphalt, etc.
Sila ʻana:Paipu Hao Ductilee hoʻohana i nā pilina maʻalahi, e like me nā sila apo kaulahao, hiki ke hoʻololi i kekahi pae o ka deformation paipu a me ka neʻe ʻana, ʻoi aku ka maikaʻi o ka sila ʻana, a hiki ke pale pono i ka leaka wai a me ka ea. ʻO nā paipu hao hao maʻamau, ʻano paʻakikī a maikaʻi ʻole ke sila.

Kaʻina hana hana
ʻO nā paipu hao hao: Ma ka hoʻohui ʻana i nā spheroidizers a me nā inoculants i ka hao i hoʻoheheʻe ʻia, a laila hana ʻia e ka hoʻoheheʻe centrifugal. ʻO kēia kaʻina hana i ʻoi aku ka paʻa o ke ʻano o ka paipu hoʻolei ʻia, a paʻa ka maikaʻi.
ʻO nā paipu hao maʻamau: ʻO ka maʻamau, hoʻohana ʻia ka hoʻolei ʻana i ke one a i ʻole nā kaʻina hoʻolei hoʻomau, a maʻalahi ke kaʻina hana, akā ʻaʻole maikaʻi ka maikaʻi a me ka hana like ʻana o kāna mau hoʻolei ʻana e like me nā paipu hao ductile.

Ka nana aku
ʻO nā paipu hao hao: He laumania ka ili, ua like ka manoanoa o ka paia, a ua maikai ka poepoe o ke kino paipu.
Paipu hao maʻamau: He oolea ka ili, a aia kekahi mau hemahema e like me na lua one a me na pores, a o ka manoanoa o ka paia paipu, aole like.

Nā hiʻohiʻona noi
Paipu hao ductile: Hoʻohana nui ʻia ia i ka lako wai o ke kūlanakauhale, ka hoʻoheheʻe ʻana, ka lawe ʻana i ke kinoea, nā ʻōnaehana pipeline ʻoihana a me nā māla ʻē aʻe me nā koi kiʻekiʻe no ka hana pipeline. ʻO ka paipu hao ʻo Ductile ka mea paipu i makemake ʻia i ka hoʻoili wai lōʻihi, ka hoʻoili wai kiʻekiʻe a me nā manawa me nā koi wai kiʻekiʻe.
Paipu hao maʻamau: Ma muli o kāna hana haʻahaʻa haʻahaʻa, hoʻohana nui ʻia ia i kekahi mau manawa kahi i kiʻekiʻe ʻole ai nā koi pipeline, e like me ke kūkulu ʻana i ka wai, ka hoʻoheheʻe ʻole a me nā ʻōnaehana ʻē aʻe.

Kumukuai
Paipu hao ductile: Ma muli o ke kaʻina hana paʻakikī a me nā koi kiʻekiʻe no nā lako maka a me nā lako hana, ʻoi aku ka maikaʻi o ke kumukūʻai i hoʻohālikelike ʻia me ka paipu hao maʻamau. Eia nō naʻe, ʻoi aku ka maikaʻi o kāna kumukūʻai piha i ka hoʻohana lōʻihi ma muli o kona ola lōʻihi a me ke kumukūʻai mālama haʻahaʻa.
Paipu hao maʻamau: He maʻalahi ke kumu kūʻai a kūpono no kekahi mau papahana me ka palena kālā a ʻaʻohe koi koʻikoʻi i ka hana pipeline.

I ka hōʻuluʻulu ʻana, hōʻike ʻia nā paipu hao ductile a me nā paipu hao hoʻolei maʻamau i nā ʻokoʻa ʻokoʻa o nā ana kī he nui. He kuleana koʻikoʻi nā paipu hao Ductile i nā kula koʻikoʻi me nā koi koʻikoʻi e pili ana i ka maikaʻi o ka pipeline a me ke kūpaʻa ma muli o ko lākou mau waiwai waiwai, hana maikaʻi a me ka ʻenehana hana kiʻekiʻe. ʻOiai ʻoi aku ka haʻahaʻa o nā paipu hao hao maʻamau i ka hana, noho lākou i kahi i nā hiʻohiʻona ʻenehana ʻenehana kikoʻī ma muli o kā lākou kumukūʻai kūpono. Ma ka hana ʻenekinia maoli a me ka hoʻomoe ʻana i ka pipeline, ʻike maopopo i ka ʻokoʻa ma waena o nā mea ʻelua a me ke koho pono ʻana i nā paipu kūpono e pili ana i nā wahi hoʻohana kikoʻī, nā koi hana a me nā palena kālā ke kī e hōʻoia i ka holomua o ka papahana, ka hana paʻa lōʻihi a me ka hoʻonui ʻana i nā pono waiwai.
