ʻO ka paipu kila ʻole: ʻo nā "ʻaʻa koko kila" o ka honua ʻoihana

I loko o nā ʻōnaehana ʻoihana hou, ʻo ka paipu kila maʻemaʻe kahi mea waiwai nui. ʻO kona ʻano maʻemaʻe e lilo ia i mea lawe kī nui no ka wai, ka ikehu, a me ke kākoʻo hoʻolālā, loaʻa iā ia ka inoa inoa "nā ipu koko kila" o ka honua ʻoihana.

ʻO ka pōmaikaʻi nui o ka paipu kila maʻemaʻe ma loko o kāna ʻano metala i hoʻohui ʻia. ʻAʻole like me nā paipu welded, kahi e koi ai i ka hoʻopili ʻana, ua hana pololei ʻia nā paipu kila maʻemaʻe mai nā billet kila paʻa i loko o nā paipu hollow ma o nā kaʻina e like me ka ʻōwili wela, kiʻi anu, a i ʻole extrusion. Hoʻopau kēia kaʻina hana i nā nāwaliwali hiki ke hoʻopaʻa ʻia i nā wili i hoʻopaʻa ʻia, ka hopena o ke kūpaʻa kiʻekiʻe o ke kaomi ʻana, ke sila ʻana, a me ka paʻa o ke kūkulu ʻana i ka wā i hoʻokau ʻia i ke kaomi kiʻekiʻe, ka wela kiʻekiʻe, ka wela haʻahaʻa, a i ʻole ka media corrosive. ʻO nā paipu ʻaila a me nā kinoea lōʻihi paha, ʻo nā paipu mahu wela wela no nā mea kanu mana, a i ʻole nā ​​ʻāpana kikoʻī i ka ʻoihana aerospace, ʻo ka paipu kila maʻemaʻe ke koho ma muli o kāna hana hilinaʻi.

Mai kahi hiʻohiʻona hana, ʻo ke kaʻina hana no ka paipu kila liʻiliʻi he paʻakikī a paʻakikī, hoʻokaʻawale ʻia i ka ʻōwili wela a me ke kiʻi anu (cold rolling). Hana ʻia nā paipu kila maʻemaʻe wela ma o nā kaʻina hana e like me ka hoʻomehana ʻana i ka billet, piercing, rolling, a me ka nui. ʻO ka huahana i hoʻopau ʻia he anawaena nui aʻe a me ka mānoanoa pā like ʻole, kūpono ia no nā hale ʻenekinia nui. ʻO nā paipu kila liʻiliʻi i huki ʻia i ke anu, i hana hou ʻia e ke kaha kiʻi anu ma hope o ka ʻōwili wela, e hoʻokō i ka pololei ʻoi aku ka nui a me ka hoʻopau ʻana i ka ʻili. Hoʻohana pinepine ʻia lākou i nā noi e koi ana i ka pololei pololei, e like me ka automotive, mīkini, a me nā mea lapaʻau.

Hoʻohana ʻia nā paipu kila ʻole ma nā ʻāpana koʻikoʻi o ka hoʻokele waiwai aupuni. I loko o ka ʻoihana ikehu, he kumu nui lākou no ka ʻili ʻana i ka aila a me ke kinoea a me nā ʻoihana pipeline, hiki ke kū i ke koʻikoʻi o lalo o ka honua a me nā kaiapuni honua paʻakikī. I ka hana ʻana i nā mīkini, ua hana ʻia lākou i nā ʻāpana koʻikoʻi e like me nā spindles mīkini hana a me nā cylinders hydraulic, e hōʻoiaʻiʻo ana i ka lawe ʻana i ka mana a me ka hana pololei. Ma nā ʻāpana hana a me nā ʻoihana hoʻolālā, hoʻohana ʻia nā paipu kila liʻiliʻi nui i nā kākoʻo hoʻolālā kila no nā hale kiʻekiʻe kiʻekiʻe a me nā alahaka, e hōʻoiaʻiʻo ana i ka palekana o ka papahana. ʻOiai i loko o nā ʻoihana kiʻekiʻe e like me ka aerospace a me ka mana nuklea, nā paipu kila maʻemaʻe i hana ʻia mai nā huila kūikawā e mālama i ka hana paʻa ma lalo o nā kūlana hana koʻikoʻi.

Me ka holomua mau o ka ʻenehana ʻenehana, ke ulu nei nā paipu kila maʻemaʻe i ka hana kiʻekiʻe a me ka hoʻomaʻemaʻe ʻoi aku. Ma o ka hoʻomohala ʻana i nā mea hao hou, ke hoʻomau nei ka hoʻomaikaʻi ʻana o ka corrosion a me ka pale wela kiʻekiʻe o nā paipu kila ʻole. ʻO ka hoʻohana ʻana i nā lako hana akamai, ʻoi aku ka pololei o ka hoʻomanawanui dimensional, e hālāwai ana i nā pono maʻamau o nā ʻoihana like ʻole. ʻOiai ʻo nā "ʻaʻa koko kila" o ka ʻōnaehana ʻoihana, nona ka ikaika a me ka paʻakikī, ua lōʻihi ka lōʻihi o nā paipu kila maʻemaʻe i kumu kumu nui no ka hoʻokele ʻana i nā hana hoʻomaikaʻi a me ka hōʻoia ʻana i ke kūkulu ʻana i nā papahana nui.
