Pipa Holoʻole Hoʻonui Wela
ʻO ka paipu kila hoʻonui wela, ʻo ia nā paipu seamless hoʻonui wela, he haʻahaʻa haʻahaʻa akā ʻo ka ʻoki ʻana o ka paipu kila ikaika (seamless pipe) hiki ke kapa ʻia he hoʻonui wela.He kaʻina hana skew rolling a kiʻi ʻana paha e hoʻonui i ke anawaena paipu.ʻO ka mānoanoa o ka paipu kila i loko o kahi manawa pōkole, hiki ke hana i nā ʻano maʻamau a me nā ʻano kūikawā o nā paipu liʻiliʻi me ka haʻahaʻa haʻahaʻa a me ka hana kiʻekiʻe o ka hana ʻana, nā hanana honua i kēia manawa i ke kahua o ka ʻōwili paipu.
ʻO ka paipu hoʻonui wela ma ka hoʻonui ʻana i ke anawaena o ka paipu e hoʻopau i nā kaʻina hana - ka hoʻonui wela wela o ka hana ʻana i ka paipu kila.Hoʻohana pinepine ʻia ka paipu hoʻonui wela i nā paipu kila ʻole.
ʻO nā ʻāpana ʻenehana o ka hoʻonui ʻana i ka wela wela ʻole i ka paipu hao ʻole:
