♦ Ka waiwai pale corrosion
He waiwai anti-corrosion kūpono ka hao, e like me ka moʻolelo, aia nā paipu hao hao i waiho ʻia ma luna o 300 mau makahiki i hala aku nei i hoʻohana ʻia, a ʻo nā hihia he nui e hōʻike ana i nā paipu hao hao i ʻoi aku ma mua o 100 mau makahiki o ke ola lawelawe.E pili ana i ka hoʻohana ʻana i nā paipu hao ductile, ʻoi aku ka mōʻaukala ma mua o 30 mau makahiki.Aka, ua aneane like ka hao ductile me ka hao hina ma ka haku mele.Loaʻa iā ia ka ʻoi aku ka nui o ke silika, carbon a me nā mea ʻē aʻe ma mua o ke kila.ʻO ke kūʻē ʻana o ka hao ductile i ka corrosion ua like pū me ka hao hina hina.Ua hōʻike ʻia kēia ma ka hoʻohana ʻana a hōʻoia i ka empirically.
♦ Ka pale ʻana i ka corrosion o ka pipeline
He ʻoiaʻiʻo, ʻo ka paipu hao ductile ma lalo o ka honua e hoʻololi ana i ka wai inu a me ke kinoea e hoʻopili nui ʻia e ka waiwai kemika a me ke kino o ka lepo.ʻO ke kumu nui loa e hiki ai ke ʻino ʻia ke hui ʻia nā paipu i mea electrify lōʻihi a mau.I nā huaʻōlelo ʻē aʻe, e hōʻike ka corrosion o ka lepo i nā hiʻohiʻona like ʻole ma nā pipeline like ʻole.Ma muli o kēia ʻokoʻa, hana ia i ka cell concentration.E ikaika loa ka hiki o ka cell concentration.Inā hoʻokomo i kahi mea uila i ka lepo e lawe mai i ka laina lōʻihi o ke au uila a laila e hana ka anode o kēia manawa i ka corrosion aboil loa.ʻO ka pipeline kila welded he laʻana maopopo.ʻO ka paipu hao ductile, nona ka hui mechanical a i ʻole T type a hoʻopaʻa ʻia e ka insulating rubber gasket, aia kahi hui insulation i kēlā me kēia 4-6 mika.
♦ Ke kū'ē i ka corrosion i hanaʻia e ka uila
No ka mea he kiʻekiʻe ke kūpaʻa uila ka hao ductile, ʻo ia ke kūʻē i ka corrosion i hoʻokumu ʻia e ka uila.
