Hana Hana

(1) Keʻano o ka hanaʻana i ke kila
Hana ʻia ke kila e ka umu uila, ka mea hoʻololi oxygen a i ʻole ke ala ahi hāmama.

(2) Ke ano hana o ka paipu blank
Hiki ke hana ʻia ka pahu blank ma ke ʻano o ka ʻōwili wela, a hiki ke hoʻohana ʻia i ka billet hoʻolei mau a i ʻole ka ingot kila.

(3) Keʻano hana o ka paipu kila
Hiki ke hana ʻia ka paipu kila e ka ʻōwili wela (extrusion, expansion) a i ʻole ke kiʻi anuanu (rolling) i ke ʻano maʻamau.

Nā hoʻāʻo

(1) Ho'āʻo Hydraulic
Pono e ho'āʻoʻia ka paipu kila i ka hydraulically.

(2) Ho'āʻo palahalaha
ʻO nā paipu kila me ke anawaena o waho ma mua o 22mm a 400mm a me ka mānoanoa o ka paia ʻaʻole i ʻoi aku ma mua o 10mm e hoʻokō ʻia i kahi hoʻāʻo palahalaha.

(3) Ho'āʻo ʻāʻā
ʻO ka paipu kila me ka mānoanoa o ka paia ʻaʻole i ʻoi aku ma mua o 8 mm hiki ke hoʻokō ʻia i kahi hoʻāʻo flare me kahi taper luna o 30 °, 45 ° a i ʻole 60 °.

(4) Ho'āʻo kūlou
ʻO nā paipu kila me ke anawaena o waho ʻaʻole iʻoi aku ma mua o 22 mm e hoʻokau ʻia i ka hoʻāʻo ʻana.

(5) Ka ho'āʻo hoʻomakeʻole
E like me nā koi o ka mea kūʻai aku, e hoʻāʻo ʻia ka paipu kila i ka ultrasonically.
