He aha ka Bright-Annealed (BA) Stainless Steel Seamless Tube？

1. Kaʻina Hana Hoʻomālamalama:

· Lewa i kāohi ʻia:
ʻO kanā paipu baua waiho ʻia i loko o kahi umu i piha i ka lewa i kāohi ʻia, ma ke ʻano maʻamau hekinoea inert(e like me ke argon a i ʻole ka naikokene) a i ʻolehoʻemi i ka hui kinoea(e like me ka hydrogen).
Pale kēia lewa i ka oxidation a mālama i ka ʻili ʻālohilohi a maʻemaʻe.

· Ka Hana Wela:
Hoʻomehana ʻia nā paipu i1,040°C a i 1,150°C(1,900°F a i 2,100°F), ma muli o ke ʻano kila kila.
Ua lawa ke kiʻekiʻe o kēia mahana e hana hou i ka hana metala, e hōʻoluʻolu i nā pilikia kūloko, a hoʻoikaika i ke kūpaʻa ʻana i ka pala.

· Hoʻomaʻalili wikiwiki (Quenching):
Ma hope o ka mālama ʻana i ka wela, hoʻomaʻalili koke ʻia nā ʻōmole i ka lewa like i kāohi ʻia e: Kāohi i ka oxidation o ka ʻili.
E laka i nā waiwai mechanical i hoʻomaikaʻi ʻia a me ka hoʻonohonoho ʻana o ka palaoa. 

2. Kūkulu ʻana me ka ʻole o ka hoʻopili ʻana:
Hana ʻia ka paipu me ka ʻole o nā ʻūmiʻi i hoʻopili ʻia, e hōʻoiaʻiʻo ana i ka like ʻana, ke kūpaʻa kiʻekiʻe o ke kaomi, a me nā waiwai mechanical kiʻekiʻe.
Hoʻokō ʻia ke kūkulu ʻana me ka maʻalahi ma o ka extrusion, ke kahakiʻi anu, a i ʻole nā ​​​​ʻano hana ʻōwili wela.
 
3. Mea Hana:
Hana pinepine ʻia mai nā kila kila e like me304/304L, 316/316L, a i ʻole nā ​​​​mea hoʻohui kūikawā ma muli o ka noi.
ʻO ke koho ʻana o ka mea e hōʻoiaʻiʻo ai i ke kūpaʻa ʻana i ka pala, ka ikaika, a me ka launa pū me nā ʻano wahi like ʻole.
 
4. Hoʻopau ʻili:
ʻO ke kaʻina hana annealing ʻālohilohi e hana i kahi ʻili laumania, maʻemaʻe, a ʻālohilohi hoʻi i ka ʻole o nā unahi a i ʻole ka oxidation.
ʻO kēia ka mea e nani ai nā ʻōmole a maʻalahi hoʻi e hoʻomaʻemaʻe, e hōʻemi ana i ka pilikia o ka haumia.
