Ka hoʻomākaukau ʻana i nā mea maʻamau → Hoʻomaʻamaʻa → Puka → ʻO ka ʻōwili → Elongation → Hoʻemi ʻia ka nui a me ka hoʻohaʻahaʻa ʻana i ka pā → Hoʻomaʻamaʻa wela → Hoʻoponopono pololei → Nānā a hoʻāʻo ʻia → ʻoki ʻana a hoʻopau i ka Huahana Huahana → Anti-corrosion lapaʻau.
Hoʻomākaukau mea maka: Pono e hoʻomaʻemaʻe ʻia nā bila e wehe i nā oxides a i ʻole nā mea haumia ʻē aʻe ma mua o ka hana ʻana.
Pumehana: Hāʻawi ʻia ka billet i loko o ka umu wela e hoʻomehana ʻia i ka mahana kūpono, ʻoi aku ma mua o 1200 ℃.
Puka: Hāʻawi ʻia ka billet i hoʻomehana ʻia i loko o ka mīkini ʻūhā, kahi e hoʻoheheʻe ʻia ai e hana i kahi billet puhaka.
Kaʻa ʻana: Ma hope o ka hou ʻana, komo ka billet i ka wili.Hele ka billet i nā hui pālua e hoʻemi mau ana i ke anawaena o waho a hoʻonui i ka lōʻihi o ka billet.
ʻO ka elongation: Hoʻonui ʻia ka billet ma o ka elongator e hoʻokō i nā kikoʻī kikoʻī kikoʻī.
ʻO ka nui a me ka hōʻemi ʻana i ka pā: ʻO ka hoʻohaʻahaʻa ʻana a me ka hoʻohaʻahaʻa ʻana i ka pā o ka billet i loko o kahi mīkini sizing e hoʻokō i ka nui kikoʻī hope loa a me ka mānoanoa o ka pā.
Hoʻoponopono wela: Pono ka paipu i ka mālama wela no ka hoʻoponopono ʻana i kāna hui metala a hoʻomaikaʻi i nā waiwai mechanical o ka mea, me nā kaʻina hana maʻamau a me ka annealing.
Hoʻoponopono pololei: Hoʻoponoponoʻia ka paipu e ka mīkini hoʻopololei e hōʻoia i ka pololei o ka paipu.
Nānā a ho'āʻo: Hana ʻia nā ʻano nānā like ʻole a me nā hoʻāʻo ʻana i ka paipu kila seamless i hoʻopau ʻia, e like me ka hydrotest, ultrasonic testing, eddy current testing, etc.
ʻOki a me ka nānā ʻana i nā huahana i pau: Eʻoki i nā paipu i nā lōʻihi i'ōleloʻia e like me nā koi o ka mea kūʻai a hana i nā nānā hope loa a me nā dimensional.
Ka lāʻau anti-corrosion: Inā pono, ua uhi ʻia ka paipu kila maʻemaʻe me ka ʻaila anti-corrosion a i ʻole nā lāʻau anti-corrosion ʻē aʻe, e like me ke galvanized; 3LPE, FBE a pēlā aku.

Hoʻomākaukau paipu Billet → Hoʻomaʻamaʻa annealing → Pickling a Lubrication → Ke kaha kiʻi anuanu → Hoʻomaʻamaʻa wela → Hoʻoponopono pololei → Nānā a hoʻāʻo → ʻOki a hoʻopau ʻia ka Huahana Huahana → Hoʻomaʻamaʻa anti-corrosion.
ʻO ka hoʻomākaukau ʻana i ka paipu billet: Ke koho 'ana i ka paipu kila li'ili'i wela e like me ka mea maka, 'o ia ho'i ka paipu billet mua.
Lapaʻau Annealing: I mea e hoopau ai i na ko'iko'i i hanaia ma ke ka'ina owili wela o na paipu billet, pono e hoopili ia na paipu billet.
Pickling and Lubrication: Ma hope o ka hoʻopili ʻana, pono e ʻoki ʻia nā paipu e wehe i ka ʻili a me ka ʻōpala.Ma hope iho, hoʻohana ʻia kahi mea lubricating i ka ʻili o ka paipu e hōʻemi i ka friction a ʻaʻahu i ka wā o ke kaʻina kaha kiʻi anu.
Kii anu: Hoʻokomo ʻia ka paipu billet ma luna o ka mīkini kaha kiʻi anu a hoʻopaʻa ʻia i loko o kahi make, kahi hana e hōʻemi ai i ke anawaena o ka paipu a me ka hoʻomaikaʻi ʻana i ka hoʻopau ʻana i ka ʻili a me ka pololei o ke ana.
Ma hope o kēlā, ʻo ka mālama wela a me nā kaʻina hana ʻē aʻe e like me ka ʻōwili wela, ʻaʻole e hana hou ʻia ma aneʻi.
