1. Kaʻina hana:
Ma muli o nā kaʻina hana ʻokoʻa o nā paipu alloy, ua hoʻokaʻawale ʻia lākou i ʻōwili wela (extrusion) maʻemaʻe a huki ʻia (rolled) Seamless ʻelua.Hoʻokaʻawale ʻia ka paipu huki anu ('ōwili) i ka paipu pōʻai a me ka paipu kino.
2. 15CrMo paipu huila Kaʻina Hana Manaʻo:
a.ʻōwili (extrusion seamless): ro und tube perforation → wela → ʻekolu-roll rolling, rolling or extrusion → detached → sizing (a hōʻemi paha) → cooling → billet tube → straightening → hydrostatic test (a i ʻole hoʻāʻo) → mark → waiho.b.ʻO ka paipu kila maʻemaʻe i huki ʻia (olokaʻi ʻia): puʻu poʻe ʻūhā → hoʻomehana → annealing → pickling → Poʻomanaʻo aila (keleawe) → kaha kiʻi anu (ʻōwili) → mālama wela → hoʻopololei i ka paipu paipu pololei → hoʻāʻo hydrostatic (hoʻāʻo) → kaha → waiho.
15CrMo huila paipu mea hoʻokahi 'ano o ka seamless kila paipu, a me kona hana i oi aku ka kiʻekiʻe ma mua o ka awelika o seamless paipu kila, no ka mea, i loko o ke kila Cr hou aku.Hiki iā ia ke mālama i ka wela kiʻekiʻe, a ʻoi aku ka maikaʻi o ka corrosion ma mua o nā hana paipu ʻole ʻē aʻe, no laila ʻoi aku ka nui o ka paipu alloy i ka ʻaila, kemika, ka mana uila, ka paila a me nā ʻoihana ʻē aʻe.Mea hoʻokūkū hoʻokūkū · Hiki iā mākou ke hāʻawi i nā paipu kikoʻī kūikawā e like me nā noi a nā mea kūʻai aku.· He mea hana mākou, no laila hiki iā mākou ke hāʻawi i nā huahana e like me kāu mau koi wikiwiki.· Loaʻa i kā mākou hui ka ikaika ʻenehana waiwai a me nā lako hana kiʻekiʻe a me ka hoʻonohonoho ʻana i nā lako hoʻokolohua holomua a me nā ʻano hana.
