ʻO ka 'loea pale ʻaʻahu' i hūnā ʻia i loko o ka pipeline: no ke aha he mea kūpono loa ka lining pipeline silicon carbide?

I ka hana ʻoihana, ua like nā paipu me nā "kīʻaha koko" o nā lako, kuleana no ka lawe ʻana i nā mea "wela" e like me ke one, ka ʻiliʻili, a me nā kinoea wela kiʻekiʻe. I ka hala ʻana o ka manawa, ua maʻalahi ka palaho ʻana o nā paia o loko o nā paipu maʻamau a hiki ke liki, e pono ai ka mālama pinepine a me ka hoʻololi ʻana, a hiki ke hoʻopaneʻe i ka holomua o ka hana ʻana. ʻO ka ʻoiaʻiʻo, ʻo ka hoʻohui ʻana i kahi papa o "nā lole pale kūikawā" i ka paipu hiki ke hoʻoponopono i ka pilikia, ʻo ia kaka uhi paipu silicon carbidee kamaʻilio ana mākou e pili ana i kēia lā.
E nīnau paha kekahi poʻe, he aha ke kumu o nā keramika silicon carbide e kani ana he "paʻakikī"? I ka ʻōlelo maʻalahi, he mea keramika ia i hana ʻia me nā mea paʻakikī e like me ka silicon carbide ma o nā kaʻina hana kūikawā, a ʻo kona hiʻohiʻona nui loa ʻo "ka paʻa": ʻo kona paʻakikī ka lua o ka daimana, a hiki iā ia ke kū i ka ʻino ʻana o ke one a me ke one a me nā mea ʻino me ka paʻa, ʻaʻole like me nā liners metala maʻamau i maʻalahi i ka popo a me ke komo ʻana, a ʻoi aku ka paʻa i nā mahana kiʻekiʻe a me nā hopena ma mua o nā liners plastic.
ʻO ke kumu o ke kau ʻana i ka uhi silicon carbide i loko o nā pipelines, ʻo ia ka hoʻohui ʻana i kahi "pale paʻa" i ka paia o loko. I ke kau ʻana, ʻaʻohe pono e hana i kahi hoʻoikaika nui. ʻO ka hapa nui o ka manawa, ua hoʻopaʻa ʻia nā ʻāpana keramika silicon carbide i hana mua ʻia i ka paia o loko o ka pipeline me nā mea hoʻopili kūikawā e hana i kahi papa pale piha. ʻAʻole paha e like me ka mānoanoa o kēia papa o ka 'pale', akā he mea pono loa kāna hana:
ʻO ka mea mua, ʻo ia ka 'pale piha ʻana i ka ʻaʻahu'. Inā paha he lawe ʻana i nā ʻāpana ore me nā kihi ʻoi a i ʻole ka slurry kahe wikiwiki, he laumania loa ka ʻili o ka uhi silicon carbide. Ke hala ka mea, he liʻiliʻi ka friction, ʻaʻole ia e hōʻino wale i ka uhi, akā e hōʻemi pū i ke kū'ē i ka wā o ka lawe ʻana i nā mea, e hoʻomaʻamaʻa ai i ka lawe ʻana. Pono paha nā pipeline maʻamau i ka mālama ʻana ma hope o ka hapalua makahiki o ke komo ʻana a me ka waimaka, ʻoiai hiki i nā pipelines me ka uhi silicon carbide ke hoʻolōʻihi nui i ko lākou ola lawelawe, e hōʻemi ana i ka pilikia a me ke kumukūʻai o ka hoʻololi pinepine ʻana i nā paipu.
A laila aia ka "pale ʻana i ka palaho a me ke kūpaʻa wela kiʻekiʻe". I nā hiʻohiʻona ʻoihana he nui, lawe nā mea i lawe ʻia i nā ʻāpana palaho e like me ka waikawa a me ka alkali, a ʻaʻole haʻahaʻa ka mahana. Ua pala a nahā nā uhi maʻamau, a i ʻole ua hoʻololi ʻia e ka hoʻomoʻa wela kiʻekiʻe. Akā, he mau waiwai kemika paʻa ko nā keramika silicon carbide a ʻaʻole makaʻu i ka ʻino ʻana o ka waikawa a me ka alkali. ʻOiai ke hōʻike ʻia i nā mahana kiʻekiʻe o kekahi mau haneli degere Celsius, hiki iā lākou ke mālama i kahi ʻano paʻa, e kūpono ai no ka hoʻohana ʻana i ka pipeline i nā "wahi ʻino" e like me ke kemika, metallurgical, a me ka mining.

ʻO kekahi mea koʻikoʻi ʻē aʻe, ʻo ia ka "hopohopo ʻole a me ka maʻalahi". ʻAʻole pono nā paipu i hoʻopaʻa ʻia me ka silicon carbide e pani pinepine no ka mālama ʻana, a maʻalahi hoʻi e mālama - ʻaʻole maʻalahi ka ʻili i ka scaling a i ʻole ke kau ʻana o nā mea, a pono wale nō e hoʻomaʻemaʻe iki ʻia i kēlā me kēia manawa. No nā ʻoihana, ʻo ia hoʻi ka hōʻemi ʻana i ka pilikia o ka hoʻopau ʻana i ka hana a me ka mālama ʻana i ka nui o nā kumukūʻai hana mālama a me nā mea, ʻo ia hoʻi ka "hoʻonohonoho hoʻokahi manawa, hopohopo lōʻihi".
Manaʻo paha kekahi poʻe he pipiʻi loa ia ʻano uhi paʻa? ʻOiaʻiʻo, ua maopopo ka helu ʻana i ka "moʻokāki lōʻihi": ʻoiai he haʻahaʻa ke kumukūʻai mua o ka uhi maʻamau, pono e hoʻololi ʻia i kēlā me kēia ʻekolu a ʻelima mahina; ʻOi aku ka kiʻekiʻe o ka hoʻopukapuka mua no ka uhi silicon carbide, akā hiki ke hoʻohana ʻia no kekahi mau makahiki, a ʻoi aku ka haʻahaʻa o ke kumukūʻai awelika i kēlā me kēia lā. Eia kekahi, hiki iā ia ke pale aku i nā pohō hana i hoʻokumu ʻia e ka pōʻino o ka pipeline, a kiʻekiʻe loa ke kumukūʻai.
I kēia mau lā, ua lilo mālie ka uhi paipu silicon carbide i "hopena makemake ʻia" no ka pale ʻana i nā paipu ʻoihana, mai nā tailings e lawe ana i nā paipu i loko o nā mines, a hiki i nā paipu mea corrosive i ka ʻoihana kemika, a hiki i nā paipu kinoea flue wela kiʻekiʻe i ka ʻoihana mana, hiki ke ʻike ʻia kona alo. I ka ʻōlelo maʻalahi, ua like ia me ke "kiaʻi kino pilikino" o nā paipu, e kiaʻi mālie ana i ka hana maʻalahi o ka hana ʻoihana me kona paʻakikī a me ke kūpaʻa - ʻo ia ke kumu e makemake ai nā ʻoihana he nui e hoʻolako i nā paipu me kēia "lole pale kūikawā".
