ʻO ke kila kalapona kila humuhumu ʻole - Royal Group

1. ʻŌwili wela (paipu kila wili ʻole extrusion): paipu poepoe hakahaka → hoʻomehana → perforating → ʻōwili diagonal ʻekolu-kiʻekiʻe, ʻōwili mau a extrusion paha → wehe ʻana → ka nui (a i ʻole ka hōʻemi ʻana) → hoʻoluʻu → hoʻopololei → hoʻāʻo hydrostatic (a i ʻole ka nānā ʻana) → māka → mālama
ʻO ka mea maka o ka ʻōwili ʻana i ka paipu wili ʻole he billet paipu poepoe, ʻoki ʻia a hana ʻia ka embryo paipu poepoe e ka mīkini ʻoki me ka ulu ʻana o kahi 1 mika blank, a hoʻouna ʻia i ka umu e ka hoʻomehana ʻana o ke kāʻei conveyor. Hoʻokomo ʻia ka billet i loko o ka umu a hoʻomehana ʻia a hiki i kahi 1200 degere Celsius. ʻO ka wahie he hydrogen a acetylene paha. ʻO ka kaohi mahana i loko o ka umu ka pilikia nui. Ma hope o ka puka ʻana mai o ka billet paipu poepoe, ua puka ʻia e ka punch pressure. ʻO ka mea maʻamau, ʻo ka perforator maʻamau ka conical roll perforator. Loaʻa i kēia ʻano perforator ka pono hana kiʻekiʻe, ka maikaʻi o ka huahana, ke anawaena perforating nui a hiki ke komo i nā ʻano kila like ʻole. Ma hope o ka perforation, ua ʻōwili mau ʻia ka billet paipu poepoe e ʻekolu diagonal kiʻekiʻe, ka ʻōwili mau a i ʻole ka extrusion. Ma hope o ka extrusion, pono e wehe ʻia ka paipu no ka nui. Hoʻohuli ka caliper i loko o ka embryo kila ma o kahi wili conical i ka wikiwiki kiʻekiʻe e punch i nā lua a hana i nā paipu kila. Hoʻoholo ʻia ke anawaena o loko o ka paipu kila e ka lōʻihi o ke anawaena o waho o ka caliper drill bit. Ma hope o ke ana ʻana i ka paipu kila, komo ia i loko o ka hale hoʻoluʻu a hoʻomāalili ʻia e ka pīpī ʻana i ka wai. Ma hope o ke hoʻomāalili ʻana i ka paipu kila, e hoʻopololei ʻia.
2. Paipu kila humuhumu anu (ʻōwili ʻia): paipu poepoe hakahaka → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → aila (plating keleawe) → kaha kiʻi anu multi-pass (ʻōwili anu) → paipu hakahaka → mālama wela → hoʻopololei → hoʻāʻo hydrostatic (nānā) → māka → mālama.
ʻOi aku ka paʻakikī o ke ʻano ʻōwili o ke kaha anu (ʻōwili) paipu kila humuhumu ma mua o ke ʻōwili wela (extrusion) paipu kila humuhumu. ʻO nā ʻanuʻu mua ʻekolu o kā lākou hana hana he like like. ʻO ka ʻokoʻa mai ka ʻanuʻu ʻehā, ka paipu poepoe hakahaka ma hope o ke kuʻi ʻana, a hiki i ke poʻo, annealing. Ma hope o ka annealing, hoʻohana ʻia ka wai waikawa kūikawā no ka pickling. Ma hope o ka pickling, hoʻopili ʻia ka ʻaila. Ma hope o kēia, ua hana ʻia kahi mālama wela kūikawā o ka paipu rebillet ma hope o ke kaha anu he nui (ʻōwili anu). Ma hope o ka mālama wela, ua hoʻopololei ʻia.
