ʻO ka paipu kila humuhumu he kila poepoe, huinahā, ʻehā me kahi ʻāpana hakahaka a ʻaʻohe humuhumu a puni. Hana ʻia nā paipu kila humuhumu me nā ingots a i ʻole nā ​​​​billets paʻa i hoʻokomo ʻia i loko o nā paipu capillary a laila ʻōwili wela, ʻōwili anu a huki anu paha.

ʻO ka paipu kila humuhumu me ka ʻāpana hakahaka, kahi nui o nā paipu i hoʻohana ʻia no ka lawe ʻana i nā wai, I ka ikaika kūlou a me ka torsion i ka manawa like, Ke hoʻohālikelike nei i ka paipu kila me ke kila poepoe a me nā kila paʻa ʻē aʻe. He māmā ke kaumaha o ka paipu kila, he ʻano ʻāpana hoʻokele waiwai o ke kila, i hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana kūkulu a me nā ʻāpana mechanical, e like me ka ʻeli ʻaila kila scaffolding.

ʻO ka hana ʻana o nā paipu kila Seamless he moʻolelo kokoke i 100 mau makahiki. Ua hana mua nā kaikunāne Kelemania Manismann i ka punch ʻōwili ʻelua-roll i ka makahiki 1885, a laila ua hana i ka mīkini ʻōwili paipu periodic i ka makahiki 1891, a ua hana ka Swiss RCStiefel i ka mīkini ʻōwili paipu aunoa (ʻike ʻia hoʻi ʻo ka mīkini ʻōwili paipu luna) i ka makahiki 1903, a me nā mīkini hoʻonui like ʻole, e like me ka mīkini ʻōwili paipu hoʻomau a me ka mīkini paʻi paipu, ua hoʻomaka e hoʻokumu i ka ʻoihana paipu kila seamless hou. I nā makahiki 1930, ua lawe ʻia ka wili paipu ʻekolu-roll.

Hoʻomaikaʻi ka mīkini paʻi extrusion a me ka wili anu anu i nā ʻano like ʻole a me ke ʻano o nā paipu kila. I ka makahiki 1960, ma muli o ka hoʻomaikaʻi ʻana o ka wili paipu hoʻomau, ʻo ka puka ʻana mai o ka punch ʻekolu-roll, ʻoiai ka holomua o ka hoʻohana ʻana i ka mīkini hoʻemi ʻana i ka haunaele a me ka billet hoʻolei mau, ua hoʻomaikaʻi i ka pono hana a hoʻonui i ka hoʻokūkū o ka paipu seamless a me ka paipu welded.

I nā makahiki 1970, ke mālama nei nā paipu wili ʻole a me nā paipu welded i kekahi i kekahi, a ke piʻi nei ka hana paipu kila o ka honua ma mua o 5% i kēlā me kēia makahiki. Mai ka makahiki 1953, ua hoʻopili nui ʻo Kina i ka hoʻomohala ʻana o ka ʻoihana paipu kila wili ʻole, a ua hoʻokumu mua i kahi ʻōnaehana hana no ka ʻōwili ʻana i nā paipu nui, waena a me nā paipu liʻiliʻi. Ma keʻano laulā, hoʻohana pū ka paipu keleawe i ke kaʻina hana o ka ʻōwili ʻana i ka billet cross a me ka perforation, ka ʻōwili ʻana i ka paipu wili a me ke kaha kiʻi ʻōwili.

Noia me ka hoʻokaʻawale ʻana o nā paipu kila humuhumu

Noi: ʻO ka paipu kila humuhumu kahi ʻano kila ʻāpana hoʻokele waiwai, he kūlana koʻikoʻi loa ia i ka hoʻokele waiwai aupuni, hoʻohana nui ʻia i ka ʻaila, ka ʻoihana kemika, ka paila, ke kahua mana, ka moku, ka hana mīkini, ke kaʻa, ka mokulele, ka aerospace, ka ikehu, ka geology, ke kūkulu ʻana a me nā ʻāpana koa.

Hoʻokaʻawale ʻana:

(1) E like me ke ʻano o ka ʻāpana i māhele ʻia i: ka ʻāpana ʻāpana poepoe, ka ʻāpana ʻāpana ʻano kūikawā

(2) e like me ka mea: paipu kila kalapona, paipu kila metala, paipu kila kila, paipu hui

(3) Wahi a ke ʻano pili: paipu pili wili, paipu kuʻihao

(4) Wahi a ke ʻano hana: paipu ʻōwili wela (extrusion, luna, hoʻonui), paipu ʻōwili anu (huki)

(5) E like me ka hoʻohana ʻana: paipu paila, paipu luawai aila, paipu paipu, paipu kūkulu, paipu mea hoʻomomona.

Kaʻina hana hana paipu kila maʻemaʻe

Ke kaʻina hana nui o ka paipu kila wili ʻole i ʻōwili wela ʻia (ke kaʻina hana nānā nui):

Hoʻomākaukau a me ka nānā ʻana i ka billet paipu → hoʻomehana ʻana o ka billet paipu → perforating → ʻōwili paipu → hoʻomehana hou ʻana i ka paipu hakahaka → hoʻopaʻa (hoʻemi) i ke anawaena → mālama wela → hoʻopololei ʻana i ka paipu i hoʻopau ʻia → hoʻopau ʻana → nānā (nondestructive, physical and kemikal, station inspection) → warehousing

(2) Ke kaʻina hana hana paipu kila wili anu (kaha kiʻi)

Hoʻomākaukau ʻana i ka billet → pickling a me ka lubrication → ʻōwili anu (kaha kiʻi) → mālama wela → hoʻopololei → hoʻopau → nānā

ʻO ka pakuhi kahe hana hana o ka paipu kila wili ʻole i ʻōwili wela ʻia penei:
