I ka hana ʻoihana, ua like nā paipu me nā "kīʻaha koko" e lawe ana i nā mea ʻānai loa e like me ka ore, ka pauka lanahu, a me ka lepo. I ka hala ʻana o ka manawa, ua maʻalahi ka ʻaʻahu ʻana i nā paia o loko o nā paipu maʻamau a lahilahi a puka i loko, e koi ana i ka hoʻololi pinepine a hiki ke hoʻopilikia i ka hana ʻana ma muli o nā leaka. I kēia manawa, kahi mea i kapa ʻia"Pai paipu pale ʻaʻahu silicon carbide"ua lilo ia i mea pono. Ua like ia me ke kau ʻana i kahi "ʻaʻahu pale pōkā" ma ka pipeline, e lilo ana i "haku" i ka hana ʻana me ka ʻaʻahu a me ka haehae ʻana o nā mea.
E nīnau paha kekahi, he aha ka silicon carbide? ʻO ka ʻoiaʻiʻo, he mea inorganic i hana ʻia me kahi ʻano paʻa loa. No ka laʻana, ʻo ka paia o loko o kahi pipeline maʻamau e like me ka papahele sima ʻinoʻino, a i ka wā e kahe ai ka mea ma o ia mea, "ʻōpala" mau ia i ka lepo; ʻO ka paia o loko o nā paipu silicon carbide e like me nā papa pōhaku paʻakikī i wili ʻia, me ke kūpaʻa haʻahaʻa a me ka ʻaʻahu māmā i ka wā e kahe ai ka mea. ʻO kēia ʻano e ʻoi aku ka ikaika o ke kūpaʻa ʻana ma mua o nā paipu kila maʻamau a me nā paipu keramika, a i ka wā e hoʻohana ʻia ai i ka lawe ʻana i nā mea ʻaʻahu kiʻekiʻe, hiki ke hoʻolōʻihi ʻia kona ola lawelawe i nā manawa he nui.
Eia nō naʻe, he palupalu ka silicon carbide ponoʻī a hiki ke haki maʻalahi ke hana pololei ʻia i loko o nā paipu. Hoʻohui ka hapa nui o nā paipu silicon carbide pale ʻaʻahu o kēia manawa i nā mea silicon carbide me nā paipu metala - ma ke kau ʻana i kahi papa o nā tile keramika silicon carbide ma ka paia o loko o ka paipu metala, a i ʻole ma ka hoʻohana ʻana i nā kaʻina hana kūikawā e kāwili i ka pauka silicon carbide a me ka mea hoʻopili, e uhi ana i ka paia o loko o ka paipu e hana i kahi papa pale ʻaʻahu ikaika. Ma kēia ʻano, loaʻa i ka paipu ka paʻakikī o ka metala, ʻaʻole maʻalahi ke hoʻololi a haki paha, a me ke kūpaʻa ʻaʻahu o ka silicon carbide, e kaulike ana i ka pono a me ke kūpaʻa.
Ma waho aʻe o ke kūpaʻa ʻana i ke komo ʻana, loaʻa i nā paipu pale ʻaʻahu silicon carbide nā pono o ke kūpaʻa wela kiʻekiʻe a haʻahaʻa a me ke kūpaʻa i ka pala. ʻAʻole wale kekahi mau mea ʻoihana he abrasive nui, akā hiki ke loaʻa nā waiwai acidic a alkaline paha. Hiki ke pala maʻalahi nā pipeline maʻamau i ka hoʻopili lōʻihi, ʻoiai he kūpaʻa ikaika ka silicon carbide i ka waikawa a me ka alkali; ʻOiai inā loli ka mahana o ka mea i lawe ʻia, ʻaʻole e hoʻopilikia nui ʻia kāna hana, a he ākea loa kāna mau hiʻohiʻona noi, mai ka mining a me ka mana a hiki i nā ʻoihana kemika a me ka metallurgical, kahi e ʻike ʻia ai kona alo.
No nā ʻoihana, ʻo ka hoʻohana ʻana i nā paipu pale ʻaʻahu silicon carbide ʻaʻole ia e pani wale i hoʻokahi mea, akā e hōʻemi pū i ke alapine o ka hoʻololi ʻana i ka paipu, e hoʻohaʻahaʻa i ke kumukūʻai o ka mālama ʻana i ka manawa downtime, a e hōʻemi i nā pōʻino palekana i hoʻokumu ʻia e ka leakage o nā mea. ʻOiai ʻoi aku ke kiʻekiʻe o kāna hoʻopukapuka mua ma mua o nā paipu maʻamau, i ka wā lōʻihi, ʻoi aku ka maikaʻi o ke kumukūʻai.
I kēia mau lā, me ka hoʻonui ʻia ʻana o ke koi no ka paʻa a me ka palekana o nā lako i ka hana ʻoihana, ke lilo nei ka hoʻohana ʻana i nā paipu pale ʻaʻahu silicon carbide i mea maʻamau. ʻO kēia "hoʻonui paipu" me he mea lā ʻaʻole nui e hūnā maoli i ka noʻeau o ka hana hou ʻana o nā mea ʻoihana, e hoʻolilo ana i ke kaʻina hana i ʻoi aku ka paʻa a me ka maikaʻi - ʻo ia ka paipu pale ʻaʻahu silicon carbide, he "loea pale ʻaʻahu" e kiaʻi mālie ana i nā "kīʻaha koko" o ka ʻoihana.
