ʻO nā paipu kila ʻole

Hana ʻia nā paipu kila ʻole me kahi ʻāpana metala holoʻokoʻa, a ʻaʻohe hili ma ka ʻili. Kapa ʻia lākou he paipu kila ʻole. Wahi a ke ʻano hana, ua māhele ʻia nā paipu seamless i nā paipu wela, nā paipu anu, nā paipu huki anu, nā paipu extruded, nā paipu jacking, a me nā mea ʻē aʻe. nā paipu ʻano kūikawā. He huinaha, oval, triangle, hexagon, hua melon, hōkū, paipu ʻēheu a me nā ʻano paʻakikī ʻē aʻe nā paipu ʻano kūikawā. ʻO 650mm ka palena kiʻekiʻe a ʻo ka palena iki he 0.3mm. E like me nā hoʻohana like ʻole, aia nā paipu pā mānoanoa a me nā paipu pā lahilahi. Hoʻohana nui ʻia nā paipu kila maʻemaʻe e like me nā paipu hoʻoheheʻe ʻana i ka petroleum geological, nā paipu hoʻoheheʻe no nā petrochemicals, nā paipu paila, nā paipu halihali, a me nā paipu kila kila kiʻekiʻe no nā kaʻa, nā trak, a me nā mokulele. He paipu kila me ka humuhumu ole ma ka aoao o kona pauku kea. Wahi a nā ʻano hana like ʻole, ua māhele ʻia i nā paipu wela, nā paipu anu, nā paipu huki anu, nā paipu extruded, nā paipu jacking, etc. ʻO nā mea e pili ana i ke kila kila maʻamau a me ke kūlana kiʻekiʻe (Q215-A ~ Q275-A a me 10 ~ 50 kila), ke kila haʻahaʻa haʻahaʻa (09MnV, 16Mn, a me nā mea'ē aʻe), ke kila kila, ke kilaʻeleʻeleʻeleʻele, a pēlā aku. i ka hoʻohana ʻana, ua māhele ʻia i ka hoʻohana maʻamau (hoʻohana ʻia no ka wai, nā pipeline gas a me nā ʻāpana hana, nā ʻāpana mechanical) a me ka hoʻohana kūikawā (hoʻohana ʻia no nā boilers, geological exploration, bearings, acid resistance, etc.). ① ʻO ke kaʻina hana nui o ka paipu kila liʻiliʻi i ʻōwili ʻia (△ Kaʻina nānā nui):
Ka hoʻomākaukau ʻana a me ka nānā ʻana o ka paipu △ → Hoʻomaʻamaʻa ʻia ka paipu → Puka paipu → Kaʻa ʻana o ka paipu → Hoʻōla hou i ka paipu hao → Nui (hōʻemi) → Hoʻomaʻamaʻa wela△→ Hoʻopau i ka hoʻopololei ʻana i ka paipu → Hoʻopau → Nānā△ (Non-destructive, physical and chemical, bench inspection) →Waehousing
② ʻO ke kaʻina hana nui o ka paipu kila maʻemaʻe i ʻōwili ʻia (huki ʻia): Paipu kila maʻemaʻe
Hoʻomākaukau hakahaka → ʻO ka ʻakika a me ka lubrication → ʻO ka ʻōwili anuanu (ke kaha kiʻi) → Hoʻomaʻamaʻa wela → Straightening → Hoʻopau → Nānā.
General seamless kila paipu hana kaʻina hana hiki ke maheleia i anu anu a me ka wela olokaa. ʻOi aku ka paʻakikī o ke kaʻina hana o ka paipu kila liʻiliʻi i ʻōwili ʻia ma mua o ka ʻōwili wela. Pono e olokaa mua ia ka paipu me na wili ekolu, a laila, pono e hanaia ka hoao ana 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 ka billet ma kahi o hoʻokahi mika ka lōʻihi. A laila e komo i ka hana annealing. Pono e hoʻopili ʻia ka Annealing me ka wai waikawa. I ka 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. I ka nana aku, ua oi aku ka pokole o na paipu kila i owiliia ma mua o na paipu kila wela. ʻOi aku ka liʻiliʻi o ka mānoanoa pā o nā paipu kila liʻiliʻi i ʻōwili ʻia ma mua o nā paipu kila hoʻoheheʻe ʻia, akā ʻoi aku ka maikaʻi o ka ʻili ma mua o nā paipu kila maʻemaʻe ʻole, a ʻaʻole ʻoʻoleʻa loa ka ʻili, ʻaʻohe o ke anawaena. nui loa nā burrs.
ʻO ke kūlana o ka lawe ʻana i nā paipu kila maʻemaʻe ʻole i ʻōwili wela ʻia a mālama ʻia me ka wela ma mua o ka lawe ʻana. Ma hope o ka nānā ʻana i ka maikaʻi, pono e koho lima ʻia nā paipu kila wili wela e nā limahana, a pono e ʻaila ʻia ka ʻili ma hope o ka nānā ʻana i ka maikaʻi, a ukali ʻia e nā hoʻokolohua kaha kiʻi anuanu. Ma hope o ka mālama ʻana i ka ʻōwili wela, pono e hoʻokō ʻia nā hoʻokolohua perforation. Inā ʻoi aku ka nui o ke anawaena perforation, pono e hoʻokō ʻia ka pololei a me ka hoʻoponopono ʻana. Ma hope o ka hoʻopololei ʻana, e lawe ʻia ka mea conveyor i ka mea ʻike kīnā no ka ʻike ʻana i ka hewa, a hoʻopaʻa inoa ʻia, hoʻonohonoho ʻia i nā kikoʻī, a waiho ʻia i loko o ka hale kūʻai.
ʻO ka puʻupuʻu puʻupuʻu billet → hoʻomehana → perforation → ʻekolu-roller oblique rolling, ʻōwili mau a extrusion → ka wehe ʻana o ka paipu → ka hoʻonui ʻana (a i ʻole e hōʻemi ana i ke anawaena) → hoʻoluʻu → hoʻopololei → hoʻāʻo kaomi hydraulic (a i ʻole ʻike kīnā) → hōʻailona → waiho ʻia ua hana ʻia ka paipu kila maʻemaʻe. o ke kila kila a i ʻole ka paipu paʻa paʻa ma ka hoʻoheheʻe ʻia ʻana i loko o ka paipu ʻōpala, a laila hana ʻia e ka ʻōwili wela, ka ʻōwili anu a i ʻole ke kiʻi anu. Hōʻike ʻia nā kikoʻī o ka paipu kila maʻemaʻe i nā millimeters o ke anawaena o waho * ka mānoanoa pā.
ʻOi aku ka nui o ke anawaena o waho o ka paipu seamless 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 e hiki ke hiki i 6mm, hiki i ka mānoanoa o ka paia ke hiki i 0.25mm, a ʻo ke anawaena o waho o ka paipu paʻa lahilahi hiki ke hiki i 5mm a ʻo ka mānoanoa o ka pā ma lalo o 0.25mm. ʻOi aku ka pololei o ke ana ʻana ma mua o ka ʻōwili wela.
ʻO ka mea maʻamau, hana ʻia nā paipu kila maʻemaʻe o 10, 20, 30, 35, 45 kiʻekiʻe kiʻekiʻe carbon steel, 16Mn, 5MnV a me nā mea hao haʻahaʻa haʻahaʻa a i ʻole 40Cr, 30CrMnSi, 45Mn2, 40MnB a me nā mea hao ʻē aʻe. ʻO 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 paipu hoʻopuka wai. Hoʻohana ʻia nā paipu seamless i hana ʻia me ke kila kalapona waena e like me 45 a me 40Cr no ka hana ʻana i nā ʻāpana mechanical, e like me nā ʻāpana ukana o nā kaʻa a me nā tractors. ʻO ka maʻamau, pono e hōʻoia nā paipu kila ʻole i ka ikaika a me ka hoʻāʻo ʻana. Hāʻawiʻia nā paipu kila wela i nā'āpana wela a wela paha; hāʻawi ʻia nā paipu kila i ʻōwili ʻia i ka wela.
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 ka lawe ʻana i ka ʻōwili ʻana o nā papa kila ma ke ʻano he laʻana, ʻo ka mānoanoa o ka billet hoʻomau mau ʻana ma kahi o 230mm, a ma hope o ka ʻōwili ʻana a me ka hoʻopau ʻana i ka ʻōwili ʻana, ʻo ka mānoanoa hope he 1 ~ 20mm. I ka manawa like, ma muli o ka liʻiliʻi o ka laulā a me ka mānoanoa o ka pā kila, ʻoi aku ka haʻahaʻa o ka pono o ka dimensional, a ʻaʻole maʻalahi ka loaʻa ʻana o nā pilikia o ke ʻano o ka pā, ka mea nui e kāohi i ka convexity. No ka poʻe me nā koi hoʻonohonoho, loaʻa maʻamau ma o ka ʻōwili ʻia ʻana a me ka hoʻoluʻu hoʻomalu ʻia, ʻo ia hoʻi, ka hoʻomalu ʻana i ka wela hoʻomaka ʻana a me ka wela o ka ʻōwili hope ʻana o ka ʻōwili ʻana. ʻO ka pila puʻupuʻu pōʻai → ka hoʻomehana → ke kī ʻana → ke poʻomanaʻo → annealing → pickling → ka ʻaila (kaupaʻa keleawe) → ka nui o nā kaha kiʻi anuanu (cold rolling) → billet tube → ka mālama wela → hoʻopololei → ka hoʻāʻo ʻana i ke kaomi wai (ʻike hewa) → hōʻailona → mālama.
