I kēia lā, ua hoʻohana nui ʻia ka paipu kila seamless i nā ʻano noi like ʻole me nā paipu aila a me ke kinoea, petrochemical a me ka ʻoihana kūkulu. Ke manaʻoʻiʻo nei paha ʻoe e hālāwai me ka huikau e pili ana i ke koho ʻana i nā huahana kila kūpono no kāu papahana. A i ʻole e hopohopo paha ʻoe inā e welded paipu kila a i ʻole paipu kila ʻole ma ka honua.
Ma ke ʻano maʻamau, ʻo nā paipu kila ka lōʻihi, ʻo nā paipu hollow i hoʻohana ʻia no nā kumu like ʻole. Ma keʻano laulā, hana ʻia lākou e nā ʻano ʻokoʻa ʻelua e hopena i ka paipu welded a i ʻole ka paipu ʻole. Ma nā ʻano ʻelua, hoʻolei mua ʻia ke kila maka i kahi ʻano hoʻomaka ʻoi aku ka hana. A laila, hana ʻia i paipu ma ka hohola ʻana i ke kila i loko o kahi paipu ʻole a i ʻole ka hoʻopaʻa ʻana i nā ʻaoʻao a hoʻopaʻa ʻia me kahi weld. ʻO ke kikoʻī, hoʻomaka ka hana ʻana i ka paipu kila maʻemaʻe me ka billet kila paʻa. Hoʻomaʻamaʻa ʻia kēia billet i ka wela nui a kikoo ʻia a huki ʻia ma luna o kahi ʻano a hiki i ke ʻano o kahi paipu puha. Ma keʻano he mea hana paipu kila kila ma Kina, makemake mākou e hāʻawi iāʻoe i kaʻike hou aku e pili ana i kēiaʻano paipu kila i hoʻohanaʻia i nā noi.
ʻO ka mea mua, ʻo ka pōmaikaʻi nui loa o nā paipu kila ʻole i ko lākou hiki ke kū i ke kaomi. ʻO ka wahi nāwaliwali loa i loko o kahi paipu kila i hoʻopaʻa ʻia ʻo ia ka wili wili. Akā, no ka mea, ʻaʻole i wili ʻia ka paipu kila maʻemaʻe, ʻaʻole i loaʻa kēlā hili ʻana, e like me ka ikaika a puni ka pōʻai holoʻokoʻa o ka paipu. ʻOi aku ka maʻalahi o ka hoʻoholo ʻana i nā helu kaomi me ka ʻole e koi ʻia e noʻonoʻo i ka maikaʻi weld. Ma kahi aʻe, ʻoiai ke kumukūʻai paipu kila i kekahi manawa e ʻoi aku ka maikaʻi ma mua o ka paipu welded. ʻO ka mea hoʻokahi, ʻo ka paipu kila maʻemaʻe kahi extrusion mau o ka alloy, ʻo ia ka mea e loaʻa iā ia kahi ʻāpana keʻa poepoe āu e hilinaʻi ai, he mea kōkua ia ke kau ʻoe i nā paipu a i ʻole ka hoʻohui ʻana i nā mea pono. No kekahi mea, ʻoi aku ka ikaika o kēia ʻano paipu ma lalo o ka hoʻouka ʻana. ʻO ka hāʻule ʻana o ka paipu a me ka hū ʻana o nā paipu welded maʻamau ke hana ʻia ma ka hili ʻana. Akā, no ka loa'a'ole o kēlā paipu li'ili'i, 'a'ole pili i kēlā mau hemahema. ʻO ka mea hope loa, ʻo ka pōmaikaʻi ʻē aʻe o nā paipu hili ʻole, ʻo ia ka hiki ke hana maikaʻi i kekahi mau kūlana koʻikoʻi, ma nā wahi anuanu a wela paha.
I ka pōkole, ua lilo ka hapa nui o nā paipu kila poepoe i mea makemake ʻia i loko o kahi ʻano o nā noi paipu pāʻoihana, e like me ke kūkulu ʻana i ka moku, nā paipu, nā ʻaila ʻaila, nā mea hana ʻaila, nā moku kaomi, nā ʻāpana mīkini a me nā rigs waho i kēia lā. Ma muli o kāu mau koi kiko'ī o nā noi, hiki iā ʻoe ke koho i ka paipu kūpono no kāu pāhana koke.
