Hana ʻia ʻo Hot Rolled Seamless Tube Production - Royal Group 

ʻO ka ʻōwili wela (extrudedpaipu kila ʻole): poepoe paipu billet→hoʻomehana→hou ʻana→ʻekolu ʻōwili keʻa, ʻōwili mau a extrusion paha→ka wehe ʻana→ka nui (a i ʻole e hōʻemi ana)→hooluolu→hoopololei ana→hoʻāʻo hydraulic (a i ʻole ka ʻike hewa)→hoailona→waihona

ʻO ka mea maka no ka ʻōwili ʻana i ka paipu liʻiliʻi he poepoe tube billet, a e ʻoki ʻia ka embryo poepoe e ka mīkini ʻoki e ulu i nā billet me ka lōʻihi o 1 mika, a lawe ʻia i ka umu e ke kāʻei conveyor. Hāʻawi ʻia ʻo Billet i loko o ka umu e wela ai, ʻo ka mahana ma kahi o 1200 degere Celsius. He hydrogen a acetylene ka wahie. ʻO ka hoʻomalu ʻana i ka mahana i loko o ka umu ahi kahi mea nui. Ma hope o ka puka ʻana o ka paipu poepoe i waho o ka umu ahi, pono e hou ʻia ma o ka ʻoi kaomi.

ʻO ka mea maʻamau, ʻo ka piercer maʻamau ka piercer huila cone. ʻO kēia ʻano piercer he kiʻekiʻe ka hana hana, maikaʻi ka huahana maikaʻi, hoʻonui nui perforation anawaena, a hiki ke komo i nā ʻano kila like ʻole. Ma hope o ka hou ʻana, ua hoʻokō ʻia ka billet puʻupuʻu poepoe i ʻekolu pōʻai o ka ʻōwili keʻa, ka ʻōwili mau ʻana a i ʻole extrusion. Ma hope o ka extrusion, pono e wehe ʻia ka paipu no ka nui. ʻO ka hoʻopaʻa ʻana i nā lua i loko o ka billet e hana i kahi paipu. Hoʻoholo ʻia ke anawaena o loko o ka paipu kila e ka lōʻihi o ke anawaena o waho o ka drill bit o ka mīkini sizing. Ma hope o ka nui o ka paipu kila, komo ia i loko o ka hale hoʻomaha a hoʻomaʻalili ʻia e ka wai. Ma hope o ka maʻalili ʻana o ka paipu kila, e hoʻopololei ʻia.

Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia ka paipu kila i ka mea ʻike kīnā metala (a i ʻole hydraulic test) e ke kāʻei conveyor no ka ʻike hewa o loko. Inā loaʻa nā māwae, nā ʻōpū a me nā pilikia ʻē aʻe i loko o ka paipu kila, e ʻike ʻia lākou. Ma hope o ka nānā ʻana i ka maikaʻi o nā paipu kila, pono ke koho lima paʻa. Ma hope o ka nānā ʻana i ka maikaʻi o ka paipu kila, e pena i ka helu serial, kikoʻī, helu pūʻulu hana, etc. me ka pena. A huki ʻia i loko o ka hale kūʻai e ka crane..
