ʻO ka 'akamai pale pale' i hūnā ʻia i loko o ka pipeline: no ke aha e hoʻomaʻamaʻa maikaʻi ai ka laina pipeline silicon carbide?

I ka hana ʻoihana, ua like nā pipeline me nā "moku koko" o nā lako, kuleana no ka lawe ʻana i nā mea "wela wela" e like me ke one, gravel, a me nā kinoea wela wela. I ka hala ʻana o ka manawa, ua maʻalahi nā paia o loko o nā pipeline maʻamau a hiki ke kahe, e koi ana i ka mālama pinepine ʻana a me ka hoʻololi ʻana, a hiki ke lohi i ka holomua o ka hana. ʻO kaʻoiaʻiʻo,ʻo ka hoʻohuiʻana i kahi papa o "nā lole pale kūikawā" i ka pipeline hiki ke hoʻonā i ka pilikia,ʻo ia kapaipu paipu kalapona silikae kamaʻilio mākou no kēia lā.
Nīnau paha kekahi poʻe, he aha ke kumu o ka silicon carbide ceramics i kani "hardcore"? ʻO ka waiho wale ʻana, he mea keramika ia i hana ʻia i nā mea paʻakikī e like me ka silicon carbide ma o nā kaʻina hana kūikawā, a ʻo kāna hiʻohiʻona nui ʻo "durability": ʻo kona paʻakikī ka lua wale nō i ka daimana, a hiki iā ia ke pale i ka hoʻoneʻe ʻana o ke one a me ka ʻiliʻili a me nā mea corrosive me ka paʻa, ʻaʻole e like me nā laina metala maʻamau e kū pono i ka ʻōpala a me ka ʻaʻahu, a ʻoi aku ke kūpaʻa ma mua o nā lālani kiʻekiʻe.
ʻO ke kumu o ka hoʻokomo ʻana i ka lining silicon carbide i loko o nā pipeline e hoʻohui i kahi "paʻa paʻa" i ka paia o loko. I ka hoʻouka ʻana, ʻaʻohe pono e hoʻoikaika nui. ʻO ka hapa nui o ka manawa, ua hoʻopaʻa ʻia nā ʻāpana seramika silicon carbide i hoʻopaʻa ʻia i ka paia o loko o ka pipeline me nā mea hoʻopili kūikawā e hana i kahi papa pale piha. ʻAʻole mānoanoa paha kēia papa o ka 'pale', akā ʻoi aku ka pono o kāna hana:
ʻO ka mea mua, ʻo ia ka 'pale lole piha'. Inā paha e lawe ana i nā ʻāpana oka me nā ʻaoʻao ʻoi a i ʻole ka slurry kahe wikiwiki, ʻoi aku ka maʻalahi o ka ʻili o ka silicon carbide lining. Ke hala ka mea, liʻiliʻi ka friction, ʻaʻole ia e hōʻino wale i ka lining, akā e hōʻemi hoʻi i ke kūʻē ʻana i ka wā o ka lawe ʻana i nā mea, e ʻoi aku ka maʻalahi o ka halihali. Pono paha nā pipeline maʻamau i ka mālama ʻana ma hope o ka hapalua makahiki o ka lole a me ka waimaka, ʻoiai nā pipelines me ka silicon carbide lining hiki ke hoʻolōʻihi i ko lākou ola lawelawe, e hōʻemi ana i ka pilikia a me ke kumukūʻai o ka hoʻololi pinepine ʻana i ka paipu.
A laila aia ka "corrosion resistance a me ke kiʻekiʻe wela ke kū'ē i nā laina lua". I nā hanana ʻoihana he nui, lawe nā mea i lawe ʻia i nā mea corrosive e like me ka waikawa a me ka alkali, a ʻaʻole haʻahaʻa ka mahana. ʻO nā lining maʻamau i ʻino a ʻāhaʻi paha, a i ʻole e hoʻoheheʻe ʻia e ka kuke wela wela. Akā ʻo ka silicon carbide ceramics iā lākou iho he mau waiwai kemika paʻa a ʻaʻole makaʻu i ka waika a me ka alkali. ʻOiai ke ʻike ʻia i nā wela kiʻekiʻe o nā haneli degere Celsius, hiki iā lākou ke mālama i kahi ʻano paʻa, e kūpono iā lākou no ka hoʻohana ʻana i ka pipeline ma nā "ʻoihana paʻakikī" e like me ke kemika, metallurgical, a me ka mining.

ʻO kekahi mea koʻikoʻi ʻo "ka hopohopo a me ka hoʻoikaika ʻole". ʻAʻole pono nā paipu i hoʻopaʻa ʻia me ka silicon carbide e pani pinepine no ka mālama ʻana, a maʻalahi hoʻi ka mālama ʻana - ʻaʻole maʻalahi ka ʻili i ka scaling a i ʻole ke kau ʻana o nā mea, a pono e hoʻomaʻemaʻe ʻia i nā manawa a pau. No nā ʻoihana, ʻo ia ke ʻano o ka hōʻemi ʻana i ka pilikia o ka hoʻopau ʻana i ka hana a me ka mālama ʻana i ka nui o ka mālama ʻana i nā limahana hana a me nā kumu waiwai, e like me ka "hoʻokomo hoʻokahi manawa, hopohopo ʻole ka manawa lōʻihi".
Manaʻo paha kekahi poʻe he mea kūʻai nui ka lining lōʻihi? ʻO kaʻoiaʻiʻo,ʻo ka heluʻana i ka "moʻolelo lōʻihi" he maopopo:ʻoiai he haʻahaʻa ke kumu kūʻai mua o ka lining maʻamau, pono e hoʻololiʻia i kēlā me kēiaʻekolu aʻelima mahina; ʻOi aku ka kiʻekiʻe o ka hoʻopukapuka mua no ka lining silicon carbide, akā hiki ke hoʻohana ʻia no kekahi mau makahiki, a ʻoi aku ka haʻahaʻa o ke kumukūʻai maʻamau i kēlā me kēia lā. Eia kekahi, hiki iā ia ke pale i nā poho o ka hana ʻana ma muli o ka pōʻino o ka pipeline, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai.
I kēia mau lā, ua lilo mālie ka lining pipeline silicon carbide i "mea makemake" no ka pale ʻana i ka pipeline ʻoihana, mai nā huelo e lawe ana i nā pipelines i nā mines, i nā pipeline material corrosive i ka ʻoihana kemika, i nā pipelines flue gas kiʻekiʻe i ka ʻoihana mana, hiki ke ʻike ʻia kona alo. ʻO ka maʻalahi, ua like ia me ka "guard bodyguard" o nā pipeline, e mālama mālie ana i ka hana maʻemaʻe o ka hana ʻoihana me kona paʻakikī ponoʻī a paʻa - ʻo ia hoʻi ke kumu e makemake ai ka nui o nā hui e hoʻolako i nā pipeline me kēia "ʻaʻahu pale kūikawā".
