1. Kaʻina Hana Hana

Paipu kila humuhumu ʻole

Hana ʻia nā paipu humuhumu ʻole mainā bila kila paʻa. Hoʻomehana ʻia ka billet a hou ʻia e hana i kahi ʻōmole hakahaka. A laila ʻōwili ʻia ka ʻōmole a huki ʻia paha i nā ana hope loa me ka hoʻohana ʻananā ʻano hana kaha kiʻi wela a i ʻole ke anu.

Nā ʻanuʻu koʻikoʻi:

l Hoʻomehana a me ka nānā ʻana o ka billet kila

l ʻO ke kuʻi ʻana o Billet e hana i ka pūpū hakahaka

l ʻōwili wela a i ʻole extrusion

l Kaha kiʻi anuanu (koho no nā paipu kikoʻī)

l Ka mālama wela, ka hoʻopololei ʻana, a me ka hoʻopau ʻana

 

Loaʻa i nā paipu humuhumu ʻoleʻaʻohe humuhumu wili, e hāʻawi ana i nā waiwai mechanical like ma ke kaʻe holoʻokoʻa.

Paipu kila i hoʻopaʻa ʻia

Hana ʻia nā paipu i hoʻopaʻa ʻia ma ka ʻōwili ʻana i nā papa kila a i ʻole nā ​​​​ʻāpana i loko o kahi ʻano cylindrical, a laila hoʻopaʻa i ke humuhumu me ka hoʻohana ʻanaKuʻihao Pale Uila (ERW), Kuʻihao Longitudinal, a i ʻole Kuʻihao Spiral.

Nā ʻanuʻu koʻikoʻi:

l Hoʻokumu ʻana i ka papa kila/ʻāpana kila

l Hoʻomākaukau ʻana a me ka hoʻopaʻa ʻana i ka lihi

l Ka mālama wela a i ʻole ka hoʻomaha ʻana i ke kaumaha (koho)

l Hoʻopololei, ana, a me ka hoʻopau ʻana

 

ʻOiai aia kahi humuhumu i loko o nā paipu i hoʻopili ʻia, nā ʻenehana holomua e like meke kaha kiʻi anu ma luna o ka mandrel (DOM)a me ka hoʻopau pololei ʻana e hoʻemi i ka ʻike ʻana o ke humuhumu a hoʻomaikaʻi i ke ʻano like.

ʻO nā paipu kila humuhumu maʻamauikaika a paʻa hoʻima mua o nā paipu i hoʻopili ʻia. ʻO nā paipu i hoʻopili pinepine ʻiaʻoi aku ka hoʻokele waiwaia kūpono nō hoʻi no nā noi ʻoihana a me nā ʻano kūkulu he nui.

 

3. Ka Pololei o ke Ana a me nā Hoʻomanawanui

Nā paipu humuhumu ʻole, ʻoi aku hoʻinā paipu humuhumu i huki anu ʻia, hāʻawinā hoʻomanawanui paʻa, ovality haʻahaʻa, a me ke pololei kiʻekiʻe. ʻO kēia ka mea kūpono iā lākou nonā ʻōnaehana mīkini kikoʻī, nā paipu kaomi kiʻekiʻe, a me nā paipu paila.

Palena	Paipu humuhumu ʻole	Paipu i hoʻopaʻa ʻia	Nā memo
Ka hoʻomanawanui o ke anawaena waho	±0.05–0.10 mm	±0.1–0.25 mm	ʻOi aku ka pololei o nā paipu humuhumu ʻole
ʻOvality	≤50% o ka hoʻomanawanui OD	≤75% o ka hoʻomanawanui OD	Hiki i ke kuʻi Weld ke hoʻopilikia i ka poepoe
Pololei	≤1/1000	≤2/1000	Hiki ke huki ʻia nā paipu humuhumu ʻole i ka pololei pololei
Mānoanoa o ka paia	±7.5%	±10%	Hāʻawi nā paipu humuhumu ʻole i ka mānoanoa like o ka paia

5. Nā noi

Nā noi paipu kila humuhumu

l Nā paipu paila a me nā paipu kaomi kiʻekiʻe

l Nā paipu hoʻololi wela

l Nā ʻōnaehana hydraulic a me ka mīkini kikoʻī

l Nā paipu petrochemical a me nā hale hoʻomaʻemaʻe

l Nā ʻōnaehana mana koʻikoʻi a me nā ʻōnaehana ikehu

 

Nā noi paipu kila i hoʻopaʻa ʻia

l Nā ʻōnaehana kūkulu

6. Nā Pōmaikaʻi a me nā Palena

Paipu humuhumu ʻole

Nā Pōmaikaʻi:

l ʻOi aku ka ikaika a me ke kū'ē'ē ʻana o ke kaomi

l Nā waiwai mechanical like

l Ke kū'ē ʻana i ka luhi kiʻekiʻe

l Nā hoʻomanawanui paʻa

7. Ke koho ʻana i ka paipu kūpono no kāu papahana

l Nā ʻōnaehana kaomi kiʻekiʻe, mahana kiʻekiʻe:Makemakenā paipu humuhumu ʻole

l Nā noi kūkulu a i ʻole nā ​​​​paipu kaomi haʻahaʻa/waena:He kūpono ke kumukūʻai o nā paipu i hoʻopili ʻia

l Nā ʻōnaehana mechanical a hydraulic paha i hoʻonohonoho pono ʻia:ʻO nā paipu humuhumu i huki ʻia i ke anu e hōʻoia i nā hoʻomanawanui paʻa a me ka ovality haʻahaʻa

Hāʻawi ʻo Womic Steel i nā paipu kila seamless a me welded, e kōkua ana i nā luna kūʻai, nā ʻenekinia, a me nā mea hana papahana e koho i ke ʻano mea kūpono, ke anawaena, ka mānoanoa o ka paia, a me ka lōʻihi e like me nā koi o ka papahana.
