ʻO ka paipu kila kekahi ʻano o ka hollow cylindrical structure

ʻO ka paipu kila he ʻano o ka hollow cylindrical structure i hana ʻia mai ka mea kila. Hoʻohana nui ʻia ia i nā ʻoihana like ʻole ma muli o kāna mau waiwai mechanical maikaʻi a me ka versatility.
ʻO ka mea i hoʻohanaʻia i ka hanaʻana i ka paipu kila,ʻo ia ke kila kalapona a iʻole ke kila kila haʻahaʻa. ʻIke ʻia ke kila kalapona no kona ikaika kiʻekiʻe a paʻa, kūpono ia no nā noi e koi ana i ke kūʻē ʻana i ka ʻaʻahu, kaomi, a me ka corrosion. Loaʻa i ka hao hao haʻahaʻa nā mea ʻē aʻe e like me ka chromium, nickel, a i ʻole molybdenum, ka mea e hoʻomaikaʻi hou ai i kona ʻano mechanical.
Hele mai ka paipu kila i nā kikoʻī like ʻole, me ka nui, ka mānoanoa o ka paia, a me ka lōʻihi. ʻO ka nui e pili ana i ke anawaena o waho o ka paipu, hiki ke piʻi mai kahi mau millimeters a i kekahi mau mika. ʻO ka mānoanoa o ka pā e hoʻoholo i ka ikaika a me ka lōʻihi o ka paipu, me nā paia mānoanoa e hāʻawi ana i ke kū'ē nui i ke kaomi a me ka hopena. Hiki ke hoʻololi i ka lōʻihi o ka paipu kila e hoʻokō i nā koi o ka papahana.
Loaʻa nā ʻano paipu kila ma muli o kā lākou hana hana. Hana ʻia ka paipu kila maʻemaʻe ma ke ʻoki ʻana i ka billet paʻa o ke kila a laila ʻolokaʻa ʻia i loko o kahi ʻano ʻāha. ʻO kēia ʻano paipu he ʻano mānoanoa like ʻole a ʻaʻohe wili i hoʻopaʻa ʻia, kūpono ia no nā noi e koi ana i ke kūpaʻa kiʻekiʻe. Hana ʻia ka paipu kila welded ma ke kuʻi ʻana a me ke kuʻi ʻana i kahi pā kila a i ʻole coil. Hoʻohana maʻamau ia no nā noi haʻahaʻa haʻahaʻa a i ʻole kahi e koi ʻia ai ka nui o ka paipu.
Loaʻa ka paipu kila i nā noi nui ma nā ʻāpana like ʻole. I ka ʻoihana aila a me ka ʻenehana, hoʻohana ʻia ka paipu kila no ka lawe ʻana i ka aila ʻaila, kinoea maoli, a me nā huahana ʻaila. Hoʻohana ʻia ia i ka ʻoihana kūkulu no nā kumu hana, e like me ke kūkulu ʻana i nā hale, nā alahaka, a me nā tunnels. Eia kekahi, hoʻohana ʻia ka paipu kila i ka lako wai a me nā ʻōnaehana wai, a me ka hana ʻana i nā kaʻa, nā mokulele, a me nā moku. Eia kekahi, hiki ke loaʻa i ka ʻoihana mahiʻai a me ka mining no ka irrigation a me ka lawe ʻana i nā minerala, kēlā me kēia.
