Hoʻokaʻawale ʻia ke kaʻina hana hana ʻana i ke kaʻina hana i loko o ka paipu wela a me ke anu.
1. Ke kaʻina hana o ka wela-'ōwili seamless paipu kila: tube billet → hoʻomehana → perforation → ʻekolu-roller/cross-rolling & hoʻomau i ka ʻōwili → de-pipe → sizing → hoʻoluʻu → straightening → hydraulic hoʻāʻo → kaha → seamless steel pipe me ka hopena leverage i ʻike ʻia.
2. Ke kaʻina hana o ke anu i huki ʻia i ka seamless steel tubes: tube blank → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → oiling → mau kaha anu → blank tube → wela → straightening → hydraulic test → marking → storage.
