Ma nā kihi o nā hale hana hale hana a me ka lawe ʻana i nā mining, aia kahi "kūlana" koʻikoʻi akā maʻalahi - ka pipeline lawe. Lawe lākou i nā minelala, mortar, a me nā mea kemika i kēlā me kēia lā, a ʻo ko lākou mau paia i loko e hoʻokau mau ʻia i ka friction a me ka hopena mai nā mea. I ka wā lōʻihi, hiki iā lākou ke ʻaʻahu a me ka waimaka, leakage, ʻaʻole ia e pili wale i ka hana akā pono pū kekahi i ka mālama a me ka hoʻololi. ʻO ka laina paipu pale silicon carbide a mākou e kamaʻilio nei i kēia lā, ua like ia me ka waiho ʻana i kahi papa o "mea kaua kila ʻike ʻole" ma nā paipu maʻamau, e hoʻoponopono mālie i kēia pilikia nui.
E nīnau paha kekahi, he aha iakalapona kalapona? ʻOiaʻiʻo, ʻaʻole ia he pohihihi. ʻO ka mea nui, he mea i hana ʻia i hana ʻia me ke kalapona a me ke silika, me ka lua o ka paʻakikī i ke daimana.
Ke hoʻohālikelike ʻia i ka paia o loko o nā pipeline maʻamau, ʻoi aku ka nui o ka paʻakikī o ka lining silicon carbide. Ke holoi ʻia nā ʻāpana ʻeleʻele ʻoi a me ka māmā holo wikiwiki i ka paia o loko, hiki i ka silicon carbide ke hana e like me ka pale e pale ai i ka hakakā a pale i nā ʻōpala a i ʻole nā niho mai ka maʻalahi. ʻOiai no ka lawe lōʻihi ʻana o nā mea lole kiʻekiʻe, hiki i kona pā i loko ke noho palahalaha a maʻalahi, me ka ʻole o ka mānoanoa a i ʻole ka palupalu ma muli o ka ʻaʻahu, e hoʻolōʻihi i ke ola lawelawe o ka pipeline.
Ma waho aʻe o ka ʻaʻahu ʻana i ke kūpaʻa, loaʻa iā ia kahi akamai huna - 'hiki ke pale i ke kūkulu ʻana'. I ka hana ʻenehana, ʻaʻole pinepine nā mea i lawe ʻia i ka "ʻāina", akā hiki ke lawe i nā wela kiʻekiʻe a me ka corrosion acid-base. No ka laʻana, ma ke kahua o ka ʻenekinia kemika, ʻoi aku ka ikaika o ka corrosiveness o kekahi mau mea, a ʻo ka lining o nā pipeline maʻamau e maʻalahi a ʻili ʻia; I ka ʻoihana metallurgical, hiki i nā mea wela kiʻekiʻe ke hana i ka deformation a me ka hemahema o ka lining. Hiki i ka silicon carbide lining ke kū i nā mahana o nā haneli he nui a kū'ē i ka hoʻoheheʻe ʻia o ka hapa nui o nā media acidic a me ka alkaline, e hoʻomau i ka hana paʻa i kekahi "kaiapuni paʻakikī".
No nā ʻoihana, ʻike maoli ʻia nā pōmaikaʻi i lawe ʻia e kēia lining liʻiliʻi: ʻaʻohe pono e pani pinepine a pani i nā pipeline, e hōʻemi ana i nā poho i hana ʻia e nā hana hoʻopau; ʻAʻole pono e hoʻokomo pinepine i nā koina mālama, hiki iā ia ke mālama i ka nui o ke kālā i ka wā lōʻihi; ʻO ka mea nui aʻe, hiki iā ia ke hōʻoia i ka lawe ʻana i nā mea waiwai a pale aku i nā pōʻino palekana a me nā pilikia kūlohelohe i hoʻokumu ʻia e ka leakage pipeline.
Mai nā paipu paipu inconspicuous a hiki i ka "mea hana pale lole" e mālama ana i ka hana ʻoihana, ʻo ka waiwai o ka silicon carbide wear-resistant pipeline lining aia i kona hiki ke "hoʻoponopono i nā pilikia nui i nā kikoʻī liʻiliʻi". No nā ʻoihana e ʻimi nei i ka hana kūpono a paʻa, ʻo ke koho ʻana ʻaʻole ia he hoʻomaikaʻi wale i nā mea hana, akā he noʻonoʻo lōʻihi hoʻi no ka hana pono a me ka hoʻokele kumukūʻai.
