He paipu kila maʻemaʻe ʻole: Hana ʻia ka paipu kila maʻemaʻe me ka ingot a i ʻole ka paipu paʻa paʻa ma o ka hoʻoheheʻe ʻia ʻana i loko o ka paipu ʻōpala, a laila ʻōwili wela, ʻōwili ʻia a huki ʻia ke anu. Hana ʻia ka mea i ke kila kalapona kiʻekiʻe e like me 10,20, 30, 35,45, haʻahaʻa alloy structural kila e like me16Mn, 5MnV a i ʻole ke kila kila e like me 40Cr, 30CrMnSi, 45Mn2, 40MnB ma ka ʻōwili wela a i ʻole ka ʻōwili anu. Hoʻohana nui ʻia nā paipu seamless i hana ʻia me ke kila kalapona haʻahaʻa e like me 10 a me 20 no nā pipeline hoʻopuka wai.
ʻO ka maʻamau, ua māhele ʻia ke kaʻina hana o nā paipu kila seamless i ʻelua ʻano: ke kaʻina huki anu a me ke kaʻina ʻōwili wela. ʻO kēia ka ʻike o ke kaʻina hana o nā paipu kila ʻole i huki ʻia i ke anu a me nā paipu kila ʻole i ʻōwili ʻia wela.
Ke kaʻina hana paipu kila maʻamau (cold-rolled). -mea hoʻopōʻino, kino a me ke kemika, ka nānā ʻana i ka pae) → waiho ʻia
Pono e hoʻokau mua ʻia nā bilets paipu kila i ʻōwili ʻia i ʻekolu ʻōwili mau, a pono e hana ʻia nā hoʻāʻo nui ma hope o ka extrusion. Inā ʻaʻohe māwae pane ma ka ʻili, pono e ʻoki ʻia ka paipu poepoe e ka mīkini ʻoki a ʻokiʻoki i loko o nā billet me ka lōʻihi o hoʻokahi mika. A laila e komo i ka hana annealing. Pono e hoʻopili ʻia ka Annealing me ka wai waikawa. I ka wā pickling, e noʻonoʻo i ka nui o nā ʻōpū ma ka ʻili. Inā nui ka nui o nā'ōhū,ʻo ia hoʻi,ʻaʻole i kūpono ka maikaʻi o ka paipu kila i nā kūlana kūpono.
ʻO ke kaʻina hana paipu kila maʻemaʻe i ʻōwili ʻia (extruded): puʻupuʻu pōʻai billet → hoʻomehana → perforation → ʻekolu ʻōwili oblique oblique, ʻōwili mau a extrusion → wehe ʻia o ka paipu → hoʻonui ʻia (a hōʻemi paha) anawaena → hoʻoluʻu → paipu billet → hoʻopololei → hoʻāʻo paʻi wai. (a i ʻole ʻike hemahema) → māka → waiho
ʻO ka'ōwili wela, e like me ka inoa, he wela kiʻekiʻe no ka'āpana'ōwili, no laila heʻuʻuku ke kū'ē deformation a hiki ke hoʻokō i ka nui deformation nui. ʻO ke kūlana o ka lawe ʻana i nā paipu kila ʻole i hoʻopaʻa ʻia i ka wela a me ka wela ma mua o ka lawe ʻana. Nānā ʻia ka paipu paʻa a wehe ʻia nā hemahema o ka ʻili, ʻoki ʻia i ka lōʻihi i makemake ʻia, e kau ʻia ma ka ʻaoʻao hope o ka ʻaoʻao perforated o ka paipu, a laila hoʻouna ʻia i ka umu wela no ka hoʻomehana ʻana a me ka perforated ma ka perforator. ʻOiai e hoʻohālua ana, ʻolokaʻi a neʻe mau i mua. Ma lalo o ka hana a nā wili a me ke poʻo, ua puka mālie kahi lua i loko o ka paipu, i kapa ʻia ʻo ia he paipu koʻikoʻi. Ma hope o ka wehe ʻia ʻana o ka paipu, hoʻouna ʻia ia i ka mīkini ʻōwili pahu pahu no ka ʻōwili hou ʻana, a laila hoʻoponopono ʻia ka mānoanoa o ka pā e ka mīkini pae, a hoʻoholo ʻia ke anawaena e ka mīkini sizing e hoʻokō i nā koi kikoʻī. Ma hope o ka mālama ʻana i ka ʻōwili wela, pono e hana ʻia kahi hoʻokolohua perforation. Inā ʻoi aku ka nui o ke anawaena perforation, pono e hoʻopololei ʻia a hoʻoponopono ʻia, a hoʻopaʻa inoa ʻia a waiho ʻia i loko o kahi waihona.
Hoʻohālikelike i ke kaʻina hana kiʻi anu a me ke kaʻina ʻōwili wela: ʻoi aku ka paʻakikī o ke kaʻina hana ʻōwili ma mua o ke kaʻina hana ʻōwili wela, akā ʻoi aku ka maikaʻi o ka ʻili, ka hiʻohiʻona, a me ka pololei o ka dimensional o nā papa kila i ʻōwili ʻia ma mua o nā papa wela, a hiki ke lahilahi ka mānoanoa o ka huahana.
Nui: ʻOi aku ka nui o ke anawaena o waho o ka paipu wili wela ma mua o 32mm, a ʻo ka mānoanoa o ka pā he 2.5-200mm. ʻO ke anawaena o waho o ka paipu kila liʻiliʻi i ʻōwili ʻia a hiki i 6mm, hiki i ka mānoanoa o ka pā a hiki i 0.25mm, ʻo ke anawaena o waho o ka paipu lahilahi a hiki i 5mm, a ʻo ka mānoanoa o ka pā ma lalo o 0.25mm ( ʻoi aku ka liʻiliʻi ma mua o 0.2mm), a ʻoi aku ka kiʻekiʻe o ka pololei o ka ʻōwili anuanu ma mua o ka ʻōwili wela.
ʻAno: ʻOiai ʻoi aku ka liʻiliʻi o ka mānoanoa o ka pā o ka paipu kila maʻemaʻe ʻole ma mua o ka paipu kila maʻemaʻe, ʻoi aku ka maikaʻi o ka ʻili ma mua o ka paipu kila ʻaʻole i ʻōwili ʻia, ʻAʻole nui nā burrs ke anawaena.
Ke kūlana hoʻouna: Hāʻawiʻia nā paipu kila wela i ka'ōwili wela a iʻole ka wela wela, a ua hāʻawiʻia nā paipu kila i ke anuanu ma ke kūlana wela.
