He poepoe, huinahalike, he kila huinahalike me ka pauku hakahaka a aohe humuhumu a puni ia.

ʻO ka paipu kila maʻemaʻe me ka ʻāpana hollow, ka nui o nā paipu i hoʻohana ʻia no ka lawe ʻana i nā wai, I ka ikaika kulou a me ka torsion i ka manawa like, Ke hoʻohālikelike ʻana i ka paipu kila me ke kila poepoe a me nā mea paʻa paʻa.

He moʻolelo ʻo Seamless steel tube production i ka makahiki 100. Ua hana mua nā kaikunāne German Manismann i ka lua-roll cross-roll punch i ka makahiki 1885, a laila hoʻokumu i ka mīkini wili manawa paipu i ka makahiki 1891, a ua hana ʻo Swiss RCStiefel i ka mīkini wili ʻakomi paipu (i ʻike ʻia ʻo ka paipu ma luna o ka ʻōwili mīkini) a me nā ʻano like ʻole o ka mīkini wili paipu 190, a me nā mea like ʻole. mīkini paʻi, hoʻomaka i ka hana ʻana i ka ʻoihana o kēia manawa seamless kila.

Hoʻomaikaʻi i ka ʻano a me ka maikaʻi o nā paipu kila. I ka makahiki 1960, ma muli o ka hoʻomaikaʻi ʻana o ka wili paipu wili mau, ka puka ʻana o ʻekolu-roll punch, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mīkini hoʻohaʻahaʻa haʻahaʻa.

I ka makahiki 1970, ke holo nei ka paipu wiliwili a me ka paipu welded me kekahi i kekahi, a ke piʻi aʻe nei ka puka o ka paipu kila honua ma mua o 5% o kēlā me kēia makahiki. kiʻi ʻōwili a me ka wili.

Palapala noia me ka hoʻokaʻawale ʻana o nā paipu kila ʻole

Noi: Seamless kila paipu mea he 'ano o ka waiwai pauku kila, he kūlana koʻikoʻi i loko o ka 'āina hoʻokele waiwai, hoʻohana nui 'ia i ka aila, kemika 'oihana, boiler, mana mana, moku, machinery manufacturing, kaʻa, mokulele, aerospace, ikehu, geology, kūkulu a me ka pūʻali koa.

Hoʻokaʻawale:

(1) E like me ke ano o ka pauku i maheleia i: poepoe pauku paipu, kūikawā

(2) e like me ka mea: carbon steel paipu, alloy steel paipu, kuhiliʻole kila paipu, composite paipu

(3) E like me ke ʻano hoʻohui: paipu pili pili, paipu kuʻi

(4) E like me ke ʻano hana: ʻōwili wela (extrusion, luna, hoʻonui) paipu, paipu anuanu (huki)

(5) E like me ka hoʻohana ʻana: paipu paila, paipu aila punawai, paipu paipu, paipu hana, paipu meaʻai.

Kaʻina hana ʻana o ka paipu kila ʻole

ʻO ke kaʻina hana nui o ka paipu kila maʻemaʻe wela (ka hana nānā nui):

Ka hoʻomākaukau ʻana a me ka nānā ʻana i ka paipu paipu → hoʻomehana ʻana i ka paipu paipu → perforating → ka paipu ʻōwili → ka hoʻomaʻamaʻa ʻana i ka paipu ʻole → ka hoʻoponopono ʻana (hoʻemi) ke anawaena → ka mālama wela → ka hoʻoponopono ʻana i ka paipu i hoʻopau ʻia → ka hoʻopau ʻana → ka nānā ʻana (nondestructive, physical and chemical, station inspection) → warehousing

(2) ʻO ke kaʻina hana hoʻoheheʻe ʻana i ke anu (ka kaha kiʻi).

ʻO ka hoʻomākaukau ʻana i ka pila → pickling a lubrication → ka ʻōwili anu (ke kaha kiʻi) → mālama wela → hoʻoponopono → hoʻopau → nānā.

ʻO ke kaʻina hana kaʻina hana o ka paipu kila seamless ʻōwili wela e like me kēia:
