Ma nā hiʻohiʻona o nā hale hana hale hana, mining, a i ʻole ka hoʻoili ʻana i ka mana, aia kekahi ʻano pipeline i "ʻike ʻole ʻia" i ka makahiki āpau akā lawe i nā kuleana koʻikoʻi - lawe pinepine lākou i ka media me nā waiwai abrasion ikaika e like me ke one, slurry, pauka lanahu, a pēlā aku. ʻO ka puka ʻana mai onā paipu kūpaʻa kūʻē i ka silika carbidee hoʻoponopono pono i kēia pilikia ʻoihana, e lilo i kahu "paʻakikī" i nā wahi kaʻa kaʻa.
He aha ke ʻano o ka pipeline pale ʻaʻahu silicon carbide?
ʻO ka ʻōlelo maʻalahi, ʻo nā paipu kūpaʻa silicon carbide he mau paipu halihali i hana ʻia ma ka hoʻohui ʻana i ka silicon carbide ma ke ʻano he mea paʻa paʻa me nā paipu metala (e like me nā paipu kila) ma o nā kaʻina hana kūikawā.
E nīnau paha kekahi, he aha ka silicon carbide? He mea hoʻoheheʻe ʻia ʻole me ka paʻakikī kiʻekiʻe, ʻelua wale nō i ke daimana. Nui nā pepa ʻeleʻele a me nā huila wili a mākou e ʻike nei i ke ola o kēlā me kēia lā i hana ʻia me ka silicon carbide. ʻO ka hoʻohana ʻana i kahi 'akamai pale pale' e hana i ka ʻili o loko o nā pipeline hiki ke hāʻawi maoli iā lākou i ke kūpaʻa ikaika loa.
Ke hoʻohālikelike ʻia me nā paipu kila maʻamau a me nā paipu pōhaku hoʻolei ʻia, ʻo ka pōmaikaʻi nui o nā paipu pale pale silicon carbide aia i ka "hoʻoponopono kūloko a me waho": ʻo ka papa silicon carbide kūloko ke kuleana no ka pale ʻana i ka ʻinoʻino a me ka ʻaʻahu ʻana o ka waena, ʻoiai ʻo ka papa metala waho e hōʻoia i ka ikaika holoʻokoʻa a me ka ikaika compressive o ka paipu. ʻO ka hui pūʻana o nā meaʻeluaʻaʻole e hoʻoponopono wale i ka pilikia o ke kū'ēʻana i ke kapa, akā e noʻonoʻo pū i ka palekana a me ka hilinaʻi o ka hoʻohanaʻana i kaʻoihana.
No ke aha e hiki ai iā ia ke 'kū'ē' i nā kaiapuni koʻikoʻi?
ʻO ka lōʻihi o nā paipu kūpaʻa silicon carbide mai nā hiʻohiʻona o ka mea silicon carbide ponoʻī.
ʻO ke kūpale ikaika loa: E like me ka mea i ʻōlelo ʻia ma mua, ʻoi aku ka paʻakikī o ka silicon carbide, a ua lohi loa kona aahu ʻana i ka ʻili o ka ʻili i ka wā lōʻihi o ka hili ʻia ʻana mai nā media granular e like me ka slurry a me ke one. Ke hoʻohālikelike ʻia me nā paipu kila maʻamau, hiki ke hoʻonui pinepine ʻia ko lākou ola lawelawe i nā manawa he nui a ʻoi aku paha ma mua o ʻumi mau manawa, e hōʻemi nui ana i ke alapine a me ke kumukūʻai o ka hoʻololi ʻana i ka pipeline.
ʻO ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa a me ka pale ʻana i ka corrosion: Ma waho aʻe o ke kūpaʻa ʻana, hiki i ka silicon carbide ke hoʻololi pū i kahi ākea ākea, a hiki ke hana paʻa i nā kaiapuni mai nā ʻumi ʻumi degere Celsius a hiki i nā haneli degere Celsius. I ka manawa like, he kūpaʻa maikaʻi nō hoʻi ia i ka media corrosive e like me ka waikawa a me ka alkali, kahi e "kūpono" ai i nā hiʻohiʻona kaʻa paʻakikī i nā ʻoihana e like me ke kemika a me ka metallurgical.
ʻO ka maikaʻi o ka lawe ʻana i ka paʻa: Ma muli o ka maʻalahi o ka lining silicon carbide, haʻahaʻa ke kūpaʻa o ka mea e kahe ana i loko o ka pipeline, ʻoi aku ka liʻiliʻi o ka blockage. ʻAʻole wale kēia e hōʻoia i ka maikaʻi o ka halihali paʻa, akā e hōʻemi hoʻi i ka downtime ma muli o ka hoʻomaʻemaʻe pipeline.
Ma hea kahi e hōʻike ai i kona akamai?
ʻOiai ke kani nei he "ʻoihana", ʻo ka hoʻohana ʻana i nā paipu kūpaʻa silicon carbide ua kokoke loa i kā mākou hana a me ke ola.
I loko o nā ʻoihana mining a me nā ʻoihana metallurgical, hoʻohana ʻia ia e lawe i ka slurry mineral mai ka mining a me nā koena ʻōpala mai ka hoʻoheheʻe ʻana, a ua hoʻokau ʻia i ka ʻaʻahu nui a me ka waimaka mai nā media particulate kiʻekiʻe;
I ka ʻoihana mana, he pipeline koʻikoʻi ia no ka lawe ʻana i ka pauka lanahu i nā mea kanu wela, e hōʻoiaʻiʻo ana i ka lako paʻa o ka wahie boiler;
I loko o nā mea hana hale a me nā ʻoihana kemika, hiki iā ia ke lawe i ka sima maka, nā mea kemika, a me nā mea ʻē aʻe, e pale aku i ka ʻaʻahu a me ka corrosion liʻiliʻi o nā media like ʻole.
Hiki ke ʻōlelo ʻia ma kēlā me kēia kahua ʻoihana e koi ai i ka lawe ʻana i ka media me ke kūpaʻa paʻa ikaika a me nā kūlana hana paʻakikī, hiki ke ʻike ʻia ka hele ʻana o nā pipelines pale silicon carbide. Hāʻawi ia i nā hōʻoia koʻikoʻi no ka hoʻomau a me ka maikaʻi o ka hana ʻana o ka ʻoihana me kāna hana "hardcore", a ua lilo hoʻi i ʻāpana koʻikoʻi o nā ʻōnaehana lawe ʻenehana hou.
