ʻO nā paipu kila liʻiliʻi i huki ʻia anukaʻina hana: puʻupuʻu poepoe → hoʻomehana → ​​perforation → Poʻomanaʻo → ​​annealing → ​​pickling → ʻaila ʻia (ke keleawe) → kahakiʻi ʻana i ke anuanu (cold rolled) → blank tube → heat treatment → straightening → hydrostatic testing (hoʻāʻo) ) → kaha → waiho.

ʻO ka puʻu kila huki ʻia me ka ʻōwili kila wela e like me ka mea maka, a ʻo ka tandem anu ʻōwili pickled e hoʻoneʻe i ka unahi oxide, kona ʻōwili paʻa paʻa paʻa, ʻōwili paʻakikī ma muli o ka hoʻololi mau ʻana o ke anuanu ma muli o ka ikaika paʻakikī, hoʻonui ʻia ka paʻakikī. paʻakikī paʻakikī, e hōʻino ka hana stamping, hiki ke hoʻohana wale ʻia no ka hoʻololi maʻalahi o nā ʻāpana.Hiki ke hoʻohana ʻia ka ʻōwili paʻa paʻa e like me ka mea maka o ka mea kanu wela wela, ka laina hoʻoheheʻe wela wela.ʻO ke kaumaha o ka ʻōwili paʻakikī maʻamau he 6 a 13.5 tons, ʻo ke anawaena coil o 610mm.

ʻO nā mea wili anu maʻamau, pono e hele ka leo ma o ka annealing mau (CAPL unit) e hoʻopau i ka paʻakikī anu a me ke koʻikoʻi o ka ʻōwili ʻana, a i ʻole ka hui ʻana i ka hui e hiki i nā waiwai mechanical o ka maʻamau e pili ana.ʻOi aku ka maikaʻi o ka ʻili kila i ʻōwili ʻia, ʻoi aku ka maikaʻi o ka nui ma mua o ka pā wela, a ʻo ka mānoanoa o nā huahana lahilahi i ʻōwili ʻia ma kahi o 0.18mm, no laila makemake ka hapa nui o nā mea hoʻohana.ʻO nā huahana mea hoʻoheheʻe kila i hoʻoheheʻe ʻia i loko o nā huahana kiʻekiʻe i hoʻohui ʻia.E like me ka electro-galvanized, hot dip galvanized, electro-galvanized fingerprint resistant, painted steel roll damping composite steel, PVC laminating steel plates, etc., no laila ka maikaʻi maikaʻi o kēia mau huahana he nani, kiʻekiʻe ke kū'ē i ka corrosion, hoʻohana nui ʻia.Hoʻopau ʻia ka pōʻai kila ʻōwili anuanu ma hope o ka hoʻopili ʻana, ʻoki i ke poʻo, huelo, ʻokiʻoki, palahalaha, paheʻe, leo kaumaha, a i ʻole ka papa clipboard longitudinal.Hoʻohana nui ʻia nā huahana cold-rolled i ka hana kaʻa, nā mea uila hale, nā mea kani, nā hoʻololi, nā hale, nā lako keʻena a me nā ʻoihana ʻē aʻe.ʻO ke kaumaha o 3 a 5 mau tona ke kaumaha o ka pā kila.ʻO ka haʻahaʻa haʻahaʻa maʻamau maʻamau 3 a 10 tons / leo.6m anawaena wili.
