Ka uhi paipu silikona carbide: "pale pale pale kūpaʻa a me ka pale ʻino" i ka halihali ʻoihana

Ma nā ʻoihana ʻoihana e like me ke kemika, ka metallurgical, a me ka eli ʻana, ʻo nā paipu nā ala nui no ka lawe ʻana i nā mea, a ʻo ka mea lawe pinepine e lawe i ka "mana pepehi" e like me ke komo ʻana, ka pala, a me ke kiʻekiʻe o ka mahana. He maʻalahi nā paipu maʻamau i ka ʻelemakule a me ka liki ʻana, ʻaʻole wale ia e hoʻopilikia i ka pono o ka hana ʻana akā ke hōʻike pū nei hoʻi i nā pōʻino palekana huna.Ka uhi ʻana o ka paipu silikona carbidehe mea pale ʻoihana i hoʻolālā ʻia e hoʻoponopono i kēia pilikia, a ua lilo ia i mea makemake nui ʻia no ka pala ikaika o ka ʻoihana a me nā kūlana ʻaʻahu kiʻekiʻe ma muli o kāna hana maikaʻi loa.
ʻO ka uhi paipu silikona carbide, ma nā huaʻōlelo maʻalahi, he papa pale o ka mea silicon carbide composite ma ka paia o loko o ka pipeline, kahi e kau ai i kahi "pale kaua" ikaika ma ka pipeline. ʻAʻole e like me nā uhi metala maʻamau a i ʻole nā ​​​​uhi plastik, ʻo silicon carbide ponoʻī he mea keramika ʻoihana koʻikoʻi me ka hiki ke hoʻololi kūlohelohe i nā kūlana hana paʻakikī, kahi e hāʻawi ai i nā uhi paipu silikona carbide i kahi pono koʻikoʻi e hoʻokaʻawale iā lākou mai nā uhi kuʻuna.
ʻO ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa ʻana i ka palaho nā mea nui o ka uhi paipu silicon carbide. I ka halihali ʻoihana, ʻo nā mea pāpaho e like me ka slurry, ka pauka, ka hopena alkali waikawa, a me nā mea ʻē aʻe he paʻakikī kiʻekiʻe a hiki ke hoʻopau ʻia nā paipu, a i ʻole he corrosiveness ikaika a hiki ke hoʻopau ʻia nā paia paipu. He paʻakikī kiʻekiʻe loa ka mea Silicon carbide, ʻo ka lua wale nō i ka daimana, a hiki ke pale maʻalahi i ka hoʻopau ʻia a me ke komo ʻana o nā mea paʻakikī like ʻole; I ka manawa like, he mau waiwai kemika paʻa kona a ʻaʻole makaʻu i ka pala waikawa a me ka alkali a i ʻole ka oxidation wela kiʻekiʻe. ʻOiai inā hana ia i nā wahi waikawa ikaika a me ka alkali, wela kiʻekiʻe no ka manawa lōʻihi, hiki iā ia ke mālama i ke kūpaʻa o ke kūkulu ʻana a hōʻemi nui i ka hiki ke hōʻino ʻia a me ka leakage o ka pipeline.
ʻO ke kūpaʻa wela kiʻekiʻe a me ka conductivity thermal maikaʻi e kūpono ia no nā kūlana hana paʻakikī. Pono e lawe ʻia nā mea he nui i ka hana ʻoihana i nā wahi wela kiʻekiʻe, a ua maʻalahi nā liners maʻamau i ka deformation a me ka ʻelemakule ma muli o nā mahana kiʻekiʻe. Eia nō naʻe, hiki i ka silicon carbide ke kū i nā mahana kiʻekiʻe loa a hoʻokō i nā koi kūikawā o nā kūlana hana wela kiʻekiʻe, e hoʻonui ana i ka laulā o nā noi pipeline.

Eia kekahi, loaʻa i ka uhi paipu silicon carbide nā pono o ke ola lawelawe lōʻihi a me ke kumukūʻai mālama haʻahaʻa. Pono ka uhi paipu kuʻuna i ka hoʻololi pinepine a me ka mālama ʻana, ʻaʻole wale ia e hoʻopau i ka hana kanaka a me nā kumuwaiwai waiwai, akā e hoʻopaneʻe pū i ka holomua o ka hana. He ikaika loa ka lōʻihi o ka uhi silicon carbide, a hiki ke hana paʻa no ka manawa lōʻihi me hoʻokahi kau ʻana, e hōʻemi nui ana i ke alapine o ka mālama ʻana a me ka hoʻololi ʻana i ke kahua ma hope. I ka wā lōʻihi, hiki iā ia ke mālama i ka nui o nā kumukūʻai hana a me ka mālama ʻana no nā ʻoihana a hōʻoia i ka hoʻomau ʻana o ka hana ʻana.
Me ka hoʻonui ʻia ʻana o ke koi no ka palekana o ka halihali, ka pono, a me ke kūpaʻa i ka hana ʻoihana, ua hoʻohana nui ʻia ka uhi paipu silicon carbide ma muli o kona mau pono koʻikoʻi o ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa ʻana i ka pala, a me ke kūpaʻa ʻana i ka mahana kiʻekiʻe. ʻAʻole wale ia he papa pale no nā paipu, akā he hōʻoia hilinaʻi hoʻi no ka hana palekana ʻoihana, ka hoʻemi ʻana i ke kumukūʻai a me ka hoʻomaikaʻi ʻana i ka pono. I ke kaʻina hana o ka hoʻomohala ʻoihana kiʻekiʻe, ke lilo nei ia i "kuleana pale kiʻekiʻe" ma ke kahua o ka halihali ʻoihana me kāna hana paʻakikī.
