I ka hana ʻoihana, ua like nā paipu me nā "kīʻaha koko" e halihali ana i nā mea, akā hiki iā lākou ke kū i nā hoʻoweliweli olakino e like me ke komo ʻana, ka pala, a me nā mahana kiʻekiʻe. ʻAʻole hiki i nā paipu maʻamau ke kū iā lākou no ka manawa lōʻihi, a ʻo ka mālama pinepine ʻana ʻaʻole wale ia e hoʻopaneʻe i ka hana ʻana akā e hoʻonui pū i nā kumukūʻai. ʻO ka puka ʻana mai oka uhi paipu silicon carbideua kau i kahi "ʻaʻahu pale paʻakikī" ma nā paipu ʻoihana, e hoʻoponopono maʻalahi ana i kēia mau pilikia.
E hoihoi paha kekahi poʻe, he aha maoli ka silicon carbide? ʻO ka ʻoiaʻiʻo, he mea keramika kūikawā ia i haku ʻia me ka silicon a me ke kalapona, e lawe maoli ana i ka gene o "paʻa a paʻa". He kiʻekiʻe loa kona paʻakikī, ʻo ka lua wale nō ma hope o ke daimana. I ka lawe ʻana i ka pauka mineral a me nā mea slurry i ke ola o kēlā me kēia lā, ʻoiai ka friction ikaika loa he paʻakikī ke waiho i nā māka ma kona ʻili. ʻAʻole e like me nā paipu metala maʻamau, e wili koke ʻia a lahilahi ʻia. A he paʻa loa kona mau waiwai kemika, inā he waikawa ikaika a me ka alkali chemical media a i ʻole corrosive slurry, ʻaʻole hiki iā lākou ke hōʻino maʻalahi iā ia, e pale ana i ka pilikia o ka pipeline corrosion a me ka leakage mai ke aʻa.
ʻO ke kūpaʻa wela kiʻekiʻe kekahi pōmaikaʻi nui o ka uhi paipu silicon carbide. I ka hana ʻoihana, pono e lawe ʻia nā mea he nui i nā wahi wela kiʻekiʻe. Hiki i nā paipu maʻamau ke hoʻololi a ʻelemakule ma lalo o ka hoʻomoʻa lōʻihi ʻana i nā mahana kiʻekiʻe, kahi e hoʻopilikia ai i ka palekana o ka halihali. A hiki i ka uhi silicon carbide ke kūpaʻa i nā mahana kiʻekiʻe loa, inā he kinoea flue wela kiʻekiʻe a i ʻole nā mea wela, hiki ke lawe maʻalahi ʻia me ke kūpaʻa piha.
Ke hoʻohālikelike ʻia me nā ʻano pale paipu kuʻuna, loaʻa i ka uhi silicon carbide kekahi mau hiʻohiʻona hopohopo ʻole. He mānoanoa kona ʻano, he laumania a pālahalaha ka ʻili, a ʻaʻole maʻalahi ke kau a kau ʻia paha i ka wā e lawe ana i nā mea. Hiki iā ia ke hōʻemi i ke koena mea a me ka ālai ʻana, a mālama i ka pono o ka lawe ʻana i ka paʻa. I ka manawa like, ʻoi aku ka haʻahaʻa o kona mānoanoa ma mua o ka metala, a ʻo ka uhi ʻana i ka pipeline ʻaʻole e hoʻonui nui i ke kaumaha holoʻokoʻa. Inā he hoʻokomo a mālama paha ma hope, ʻoi aku ka maʻalahi a hiki ke hōʻemi i ke kaumaha o ke kau ʻana o ka pipeline, e hoʻololi ana i nā hiʻohiʻona ʻoihana paʻakikī.
He mea kūpono ke haʻi ʻia ʻo ka inertness kemika o ka silicon carbide ponoʻī e pale aku iā ia mai ka pane ʻana me nā mea i lawe ʻia. ʻOiai no nā mea me nā koi maʻemaʻe kiʻekiʻe, ʻaʻohe pono e hopohopo e pili ana i ka haumia i hana ʻia e ka hui ʻana o nā mea uhi. Inā he mea maka maikaʻi ia i ka ʻoihana kemika a i ʻole nā pauka maʻemaʻe kiʻekiʻe i ka ʻoihana ikehu hou, hiki ke lawe ʻia me ka hilinaʻi. He kumu nui nō hoʻi kēia no ke koho ʻana o nā kahua ʻoihana kiʻekiʻe he nui.
I kēia mau lā, ua lilo ka uhi paipu silicon carbide i "loea pale" ma ke kahua o ka halihali ʻoihana, mai ka halihali ʻana i nā mea nui i nā mines a me ka mana wela a hiki i ka halihali waena maikaʻi i nā kemika a me nā pila lithium, hiki ke ʻike ʻia kona alo. Hoʻohana ia i kāna hana maikaʻi loa e kōkua i nā ʻoihana e hōʻemi i ka pinepine o ka mālama ʻana i nā paipu, hoʻolōʻihi i ke ola lawelawe o nā lako, a hoʻolilo i ka halihali ʻoihana i ʻoi aku ka maikaʻi a me ka palekana.
Ma ke ʻano he poʻe loea i ke kahua o nā keramika ʻoihana silicon carbide, ua hoʻomaʻemaʻe mau mākou i ka maikaʻi o nā liners pipeline silicon carbide, me ka hoʻohana ʻana i nā huahana e hoʻokō pono ai i nā pono ʻoihana e hōʻoia i ka hana paʻa ma nā ʻoihana like ʻole. E ʻae i kēia papa o "nā lole pale paʻakikī" e kiaʻi i ka "laina ola" o ka halihali ʻoihana hou aku.
