Ka uhi ʻana o ka paipu silikona carbide: ke "pale pale" no nā paipu ʻoihana

I ka hana ʻoihana, ua like nā paipu me nā "kīʻaha koko" o nā hale hana, kuleana no ka lawe ʻana i nā wai like ʻole, nā kinoea, a me nā ʻāpana paʻa. Eia nō naʻe, he ikaika ka ʻino o kekahi o kēia mau mea hana a me ke kūpaʻa ʻana i ka ʻaʻahu ʻana, hiki ke waiho i nā paipu i ʻeha i ka hala ʻana o ka manawa. ʻAʻole wale kēia e hoʻopilikia i ka pono o ka hana ʻana akā hiki ke hoʻopilikia i ka palekana.
I kēia manawa, he ʻenehana pale paipu kūikawā -ka uhi paipu silicon carbide, ke lilo mālie nei i mea makemake ʻia no nā ʻoihana he nui.
He aha ka silicon carbide?
ʻO Silicon carbide (SiC) kahi hui i haku ʻia me ka silicon a me ke kalapona, kahi e hoʻohui ai i ke kūpaʻa wela kiʻekiʻe a me ka palaho o nā keramika me ka paʻakikī kiʻekiʻe a me ke kūpaʻa hopena o nā metala. ʻO kona paʻakikī ka lua wale nō i ka daimana, e lilo ia i mea makemake nui ʻia ma ke kahua o nā mea pale i ke komo ʻana.
No ke aha e hoʻohana ai i ka silicon carbide no ka uhi ʻana o ka pipeline?
I ka ʻōlelo maʻalahi, ʻo ka uhi silicon carbide he papa o "pale pale" i kau ʻia ma ka paia o loko o kahi paipu. ʻO kona mau pono nui:
1. Kūpaʻa loa i ke kapa komo
ʻO ka paʻakikī kiʻekiʻe o ka silicon carbide e hiki ai iā ia ke pale maʻalahi i ka ʻino ʻana o nā mea hana kiʻekiʻe e like me ka mortar a me ka slurry.
2. Ke kūpaʻa ʻana i ka palaho
Inā paha i loko o nā hopena waikawa, alkali a paʻakai paha, hiki i ka silicon carbide ke noho paʻa a ʻaʻole e maʻalahi ka ʻino ʻia.
3. Ke kū'ē ʻana i ka mahana kiʻekiʻe
ʻOiai ma nā wahi wela kiʻekiʻe o nā haneli degere Celsius, hiki i ka uhi silicon carbide ke mālama i ke kūpaʻa kūkulu me ka ʻole o ka deformation a i ʻole ka hemo ʻana.
4. E hoʻolōʻihi i ke ola o nā paipu
Ma ka hōʻemi ʻana i ke kapa a me ka pala, hiki i ka lining silicon carbide ke hoʻolōʻihi nui i ke ola lawelawe o nā pipelines, e hōʻemi i ka alapine hoʻololi a me nā kumukūʻai mālama.
Nā hiʻohiʻona noi
Hoʻohana nui ʻia ka uhi paipu silikona carbide i nā ʻoihana e like me ke kemika, ka mining, ka mana, a me ka palekana o ke kaiapuni, a kūpono loa ia no ka lawe ʻana i nā mea hana e hoʻoulu ai i nā pohō nui o ka paipu, e like me:
-Slurry e loaʻa ana nā ʻāpana paʻa
-Hoʻonā ʻino ikaika
- Kinoea flue wela kiʻekiʻe a wai paha

hōʻuluʻulu manaʻo
ʻO ka uhi ʻana o ka paipu silikona carbide e like me ka hoʻohui ʻana i kahi "pale pale" paʻa i ka paipu, hiki ke pale aku i ka ʻaʻahu a me ka pala, a me ke kū ʻana i nā wahi wela kiʻekiʻe, a he hōʻoia hilinaʻi ia no ka hana paʻa lōʻihi o nā paipu ʻoihana. No nā ʻoihana e alualu ana i nā hana kūpono, palekana, a me ke kumukūʻai haʻahaʻa, he hoʻolālā hoʻonui kēia e pono ke noʻonoʻo ʻia.
