Pehea e wehe ai i ka unahi oxide ma nā paipu huinahā nui?

Hoʻohana ʻia ka solvent a me ka emulsion e hoʻomaʻemaʻe i ka ʻili opaipu huinahā nui ke anawaenae wehe i ka ʻaila, ka momona, ka lepo, ka lubricant a me nā mea olaola like. Eia nō naʻe, ʻaʻole hiki iā ia ke wehe i ka ʻōpala, ka unahi oxide a me ke kahe ma luna o ka ʻili o ka paipu huinahā nui, no laila hoʻohana wale ʻia ia ma ke ʻano he mea kōkua i ka hana anti-corrosion.

Ma keʻano laulā, hoʻohana ʻia nā ʻano kemika a me ka electrolytic no ka mālama ʻana i ka pickling. Hoʻohana wale ʻia ka pickling kemika no ka pipeline anticorrosion, hiki ke wehe i ka unahi oxide, ka popo a me ka uhi kahiko. I kekahi manawa, hiki ke hoʻohana ʻia e like me ka hana hou ʻana ma hope o ka pahū ʻana o ke one. ʻOiai hiki i ka hoʻomaʻemaʻe kemika ke hoʻolilo i ka ʻili i kahi pae o ka maʻemaʻe a me ka ʻoʻoleʻa, he pāpaʻu kona ʻano heleuma a maʻalahi hoʻi e hoʻohaumia i ke kaiapuni a puni. Pono e waiho ʻia nā paipu huinahā nui no ka ʻae ʻia ma nā ʻāpana, a pono e kūlike nā lula ʻāpana me nā ʻōlelo o nā kūlana huahana pili.

Pono nā mea nānā, nā nui laʻana, nā kūlana laʻana a me nā ʻano hoʻāʻo o nā paipu huinahā nui e kūlike me nā ʻōlelo o nā kūlana huahana pili. Me ka ʻae ʻana o ka mea noi, ʻo ka ʻōwili welanā paipu huinahā nuihiki ke laʻana ʻia i loko o nā pūʻulu e like me nā hui aʻa i ʻōwili ʻia.

Inā ʻaʻole i kūpono nā hopena hoʻāʻo o nā paipu huinahā nui i nā koi o nā kūlana huahana, e koho ʻia nā mea kūpono ʻole, a e lawe ʻia ka helu pālua o nā laʻana mai ka pūʻulu like o nā paipu huinahā nui no ka nānā hou ʻana i nā mea kūpono ʻole. Inā ʻaʻole kūpono ka hopena nānā hou (me kekahi helu kuhikuhi i koi ʻia e ka hoʻāʻo papahana), ʻaʻole e hāʻawi ʻia ka pūʻulu o nā paipu huinahā nui. Inā ʻaʻole i hala nā mea nānā ma lalo nei i ka nānā mua ʻana, ʻaʻole ʻae ʻia ka nānā hou ʻana: a Aia nā kiko keʻokeʻo i loko o ka ʻiʻo macroploid; b. Microstructure.
