ʻO ke kūʻai pololei ʻana o ka paipu kila seamless o nā mea like ʻole

1.'Oloka'a 'ia ka paipu kila ma'amau ma'amau e ke kila kalapona ma'amau, ke kila ho'ohehe'e ha'aha'a a i 'ole ke kila kila kila, me ka mea nui loa. Hoʻohana nui ʻia e like me ka pipeline a i ʻole nā ​​​​ʻāpana hana no ka lawe ʻana i ka wai.

2. ʻEkolu ʻano o ka lako e like me nā kumu like ʻole:

a. Hāʻawi e like me ka haku mele a me nā waiwai mechanical;

b. Hoʻolako e like me nā waiwai mechanical;

c.Hāʻawi ʻia e like me ka hoʻāʻo hydrostatic. Inā hoʻohana ʻia ka paipu kila i hāʻawi ʻia e like me ka papa A a me B no ka lawe ʻana i ke kaomi wai, e kau ʻia nō ia i ka hoʻāʻo hydrostatic.

3. ʻO nā paipu hili ʻole no nā hana kūikawā, ʻo ia nā paipu ʻole no ka paila, kemika a me ka mana uila, nā paipu kila maʻemaʻe no ka geology a me nā paipu seamless no ka ʻaila.

ʻO ka paipu kila maʻemaʻe he ʻāpana ʻāpana a hoʻohana nui ʻia e like me ka pipeline no ka lawe ʻana i ka wai, e like me ka pipeline no ka lawe ʻana i ka aila, ke kinoea maoli, ke kinoea, ka wai a me kekahi mau mea paʻa. Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻoi aku ka ikaika o ka flexural a me ka torsional a me ke kaumaha o ka paipu kila. He kila pauku waiwai.

Hoʻohana nui ia no ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka paipu ʻaila hinu, ka pahu hoʻoili kaʻa, ka pahu kaʻa a me ka scaffold kila i hoʻohana ʻia i ke kūkulu ʻana. Hiki iā ia ke hoʻomaikaʻi i ka hoʻohana ʻana i nā mea, hoʻomaʻamaʻa i ke kaʻina hana, mālama i nā lako a me nā hola hana. Ua hana nui ia me ka paipu kila.

① ʻO ke kaʻina hana nui o ka paipu kila liʻiliʻi wela (△ kaʻina nānā nui):

Ka hoʻomākaukau ʻana a me ka nānā ʻana i ka paipu blank △ → hoʻomehana ʻana o ka paipu blank → perforation → ka ʻōwili ʻana o ka paipu → ka hoʻomaʻamaʻa ʻana o ka paipu kila → ka nui (hoʻemi) → ka mālama wela △ → ka hoʻoponopono ʻana i ka paipu i hoʻopau ʻia → ka hoʻopau ʻana → ka nānā ʻana △ (nondestructive, physical and chemical, bench inspection ) → hale kūʻai

② ʻO nā kaʻina hana nui o ka paipu kila liʻiliʻi i ʻōwili ʻia (kau ʻia):

Hoʻomākaukau hakahaka → pickling a lubrication → ʻōwili anu (kahakiʻi) → mālama wela → hoʻopololei → hoʻopau → nānā.

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana maʻamau o ka paipu kila ʻole i ke kiʻi anu a me ka ʻōwili wela. ʻOi aku ka paʻakikī o ke kaʻina hana o ka paipu kila liʻiliʻi liʻiliʻi ma mua o ka ʻōwili wela. Pono mua ka paipu blank i ʻekolu ʻōwili mau, a e hoʻokō ʻia ka hoʻāʻo ʻana ma hope o ka extrusion. Inā ʻaʻole pane ka ʻili i ka māwae, pono e ʻoki ʻia ka paipu poepoe e ka mea ʻoki e ʻoki i ka blank me ka ulu ʻana o hoʻokahi mika. A laila e komo i ka hana annealing. E hoʻopili ʻia ka annealing me ka wai waikawa. I ka wā pickling, e hoʻolohe i ka nui o nā ʻōhū ma ka ʻili. Inā loaʻa ka nui o nā puʻupuʻu, e hōʻike ana i ka maikaʻi o ka paipu kila ʻaʻole hiki ke hoʻokō i nā kūlana kūpono. ʻOi aku ka pōkole o ke ʻano o ka paipu kila liʻiliʻi i ʻōwili ʻia ma mua o ka paipu kila wela. ʻOi aku ka liʻiliʻi o ka mānoanoa o ka pā o ka paipu kila liʻiliʻi i ʻōwili ʻia ma mua o ka paipu kila maʻemaʻe ʻole, akā ʻoi aku ka mālamalama o ka ʻili ma mua o ka paipu kila ʻole. ʻAʻole ʻoʻoleʻa loa ka ʻili a ʻaʻole nui loa ke anawaena.

ʻO ke kūlana o ka hāʻawi ʻana i ka paipu kila maʻemaʻe ʻole i ʻōwili ʻia i ka wela a hāʻawi ʻia ma hope o ka mālama ʻana i ka wela. Ma hope o ka nānā ʻana i ka maikaʻi, e koho pono ʻia ka paipu kila seamless wela e nā limahana. Ma hope o ka nānā ʻana i ka maikaʻi, e ʻaila ʻia ka ʻili, a ukali ʻia e nā hoʻokolohua kiʻi anuanu. Ma hope o ka ʻōwili wela, e hoʻokō ʻia ka hoʻokolohua perforation. Inā nui loa ka hoʻonui ʻia ʻana, e hoʻopololei ʻia a hoʻoponopono ʻia. Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia i ka mea ʻike kīnā e ka conveyor no ka hoʻāʻo ʻike hewa. ʻO ka hope, ua hōʻailona ʻia a waiho ʻia i loko o ka hale kūʻai ma hope o ka hoʻonohonoho kikoʻī.

ʻO ka paipu pōʻai → ka hoʻomehana ʻana → perforation → ʻekolu ʻōwili keʻa kaʻa, ka ʻōwili mau ʻana a i ʻole extrusion → ka wehe ʻana i ka paipu → ka nui (a i ʻole ka hoʻohaʻahaʻa ʻana) → hoʻoluʻu → hoʻopololei → hoʻāʻo hydrostatic (a i ʻole ka ʻike kīnā) → hōʻailona → hale kūʻai ʻana i ka paipu kila maʻemaʻe. a i ʻole ka paipu paʻa paʻa ʻole ma o ka perforation, a laila ʻōwili wela, ʻōwili anu a huki ʻia paha. Hōʻike ʻia ka ʻōlelo kikoʻī o ka paipu kila ʻole i ka mm o ke anawaena o waho * ka mānoanoa pā.

ʻOi aku ka nui o ke anawaena o waho o ka paipu wela ʻole 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 liʻiliʻi hiki ke piʻi i ka 6mm, hiki i ka mānoanoa o ka paia ke hiki i ka 0.25mm, hiki ke anawaena o waho o ka paipu lahilahi a hiki i ka 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 me nā kila carbon hoʻopaʻa kiʻekiʻe e like me 10, 20, 30, 35 a me 45, nā kila kila haʻahaʻa haʻahaʻa e like me 16Mn a me 5mnv, a i ʻole nā ​​kila i hoʻopaʻa ʻia e like me 40Cr, 30CrMnSi, 45MnB2 a me 40MnB. 10. Hoʻohana nui ʻia nā paipu seamless i hana ʻia me ke kila kalapona haʻahaʻa e like me 20 no nā paipu hoʻoili wai. Hoʻohana ʻia nā paipu seamless i hana ʻia me ke kila kalapona maʻamau e like me 45 a me 40Cr e hana i nā ʻāpana mechanical, e like me nā ʻāpana koʻikoʻi o nā kaʻa a me nā tractors. ʻO ka maʻamau, e hōʻoia ʻia ka ikaika a me ka hoʻāʻo ʻana o ka paipu kila seamless. ʻO nā paipu kila ʻōwili wela e hāʻawi ʻia i ka moku'āina ʻōwili wela a i ʻole ke kūlana mālama wela; Hāʻawi ʻia ka ʻōwili anuanu ma ke kūlana mālama ʻia.

ʻO ka'ōwili wela, e like me ka inoa, ua kiʻekiʻe ka mahana o ka'āpana'ōwili, no laila he liʻiliʻi ke kū'ē o ka deformation a hiki ke hoʻomaopopo i ka deformation nui. ʻO ka lawe ʻana i ka ʻōwili ʻana o ka pā kila ma ke ʻano he laʻana, ʻo ka mānoanoa o ka hoʻoheheʻe hoʻomau ʻana ma kahi o 230mm, ʻoiai ma hope o ka ʻōwili ʻana a hoʻopau i ka ʻōwili ʻana, ʻo ka mānoanoa hope he 1 ~ 20mm. I ka manawa like, no ka mea he liʻiliʻi ka laulā mānoanoa o ka pā kila a he haʻahaʻa loa nā koi no ka pololei dimensional, ʻaʻole maʻalahi ka pilikia o ke ʻano, a ʻo ka convexity ka mea e hoʻomalu nui ʻia. No ka poʻe me nā koi hoʻonohonoho, ʻike ʻia ma o ka ʻōwili ʻia ʻana a me ka hoʻoluʻu ʻana, ʻo ia hoʻi, e hoʻomalu i ka wela hoʻomaka ʻana a me ka wela o ka ʻōwili hope ʻana o ka ʻōwili ʻana. Poʻe pōʻaiapuni blank → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → ʻaila (kaupaʻa keleawe) → multi pass anu kiʻi (cold rolling) → blank tube → wela → straightening → hydrostatic test (flaw detection) → marking → warehousing.
