Hana ʻia nā paipu welded me nā papa kila a i ʻole nā ​​ʻāpana kila i pelu ʻia a laila wili ʻia. E like me ke ʻano o ka humuhumu kuʻi ʻana, ua māhele ʻia i loko o ka paipu wili wili pololei a me ka paipu wiliwili spiral.
Wahi a ke kumu, ua māhele ʻia lākou i loko o nā paipu welded maʻamau, nā paipu welded galvanized, nā paipu welded oxygen-blown, nā pahu uwea, nā paipu metric welded, nā paipu wili, nā paipu wai hohonu, nā paipu automotive, nā paipu transformer, nā paipu uila wiliwili ʻia i ka paia. .
Paipu welded maʻamau: Hoʻohana ʻia ka paipu welded maʻamau no ka lawe ʻana i nā wai haʻahaʻa haʻahaʻa. Hana ʻia me Q195A, Q215A, Q235A kila. Hiki ke hana ʻia me nā kila māmā ʻē aʻe i hiki ke weldable. Pono nā paipu kila e hana i nā hoʻokolohua e like me ke kaomi hydraulic, ka piko, a me ka palahalaha, a loaʻa kekahi mau koi no ka maikaʻi o ka ʻili. ʻO ka maʻamau, ʻo 4-10m ka lōʻihi o ka lawe ʻana, a koi pinepine ʻia ka hāʻawi ʻana i ka lōʻihi paʻa (a i ʻole nā ​​​​mau lōʻihi).
Hōʻike ʻia nā kikoʻī o nā paipu welded i ke anawaena nominal (millimeters a i ʻole iniha). ʻOkoʻa ke anawaena nominal mai ka mea maoli. E like me ka mānoanoa o ka paia, ʻelua ʻano paipu welded: ʻo nā paipu kila maʻamau a me nā paipu kila mānoanoa. ʻO kēia ka hoʻolauna pōkole i ka hoʻohana ʻana i kekahi mau paipu paʻakikī:
1. Hoʻohana ʻia nā paipu welded maʻamau no ka lawe ʻana i nā wai haʻahaʻa haʻahaʻa e like me ka wai, ke kinoea, ka ea, ka ʻaila, a me ka mahu mehana.
2. ʻO nā lima lima uea kalapona maʻamau (GB3640-88) he mau paipu kila i hoʻohana ʻia no ka pale ʻana i nā uea i ka wā e hoʻokomo ai i nā uila e like me nā hale ʻoihana a me nā hale kīwila a me ka hoʻokomo ʻana i nā mīkini a me nā mea hana.
3. ʻO ka paipu wili uila pololei (YB242-63). Hoʻokaʻawale pinepine ʻia i nā paipu wili uila metric, nā paipu wiliwili wiliwili i ka paia, nā paipu aila hoʻoheheʻe transformer, etc.
4. He paipu wiliwili ʻia i loko o ke ao no ka lawe ʻana i ka wai (SY5036-83) he paipu wiliwili ʻia no ka lawe ʻana i ka wai. Hana ʻia ʻo ia me nā ʻōwili kila ʻōwili wela a hoʻokumu ʻia i ka wela mau. Hoʻopili ʻia ia e ka lua-ʻaoʻao submerged arc welding. He paipu wiliwili ʻia i loko o ka wai no ka lawe ʻana i ka wai humuhumu kila. Loaʻa i nā paipu kila ka mana ikaika a me ka hana wiliwili maikaʻi. Ua loaʻa iā lākou nā ʻike ʻepekema koʻikoʻi a me nā hoʻāʻo a palekana a hilinaʻi hoʻi e hoʻohana. ʻO ka paipu kila he anawaena nui, kiʻekiʻe ka lawe ʻana i ka maikaʻi, a hiki ke mālama i ka hoʻopukapuka ʻana i ka waiho ʻana i nā pipelines. Hoʻohana nui ʻia no nā pipeline e lawe ana i ka aila a me ke kinoea maoli.
5. Hoʻopili ʻia ka wili wiliwili kiʻekiʻe alapine (SY5038-83) no ka lawe ʻana i ka wai me ka wela o ka ʻōwili kila e like me ka paipu blanks, ua hoʻokumu ʻia i ka wela mau, a welded e ke ala kiʻekiʻe alapine wili ʻana. Hoʻohana ʻia ia no ka lawe ʻana i ka wai hoʻoluhi. Piula kila kiʻekiʻe i wiliwili ʻia. ʻO nā paipu kila he ikaika ikaika, a me ka plasticity maikaʻi, a ua maʻalahi ka weld a me ka hana. Ma hope o nā hoʻokolohua koʻikoʻi a me ka ʻepekema, palekana lākou a hilinaʻi hoʻi e hoʻohana. ʻO nā paipu kila he nui nā anawaena, kiʻekiʻe ka lawe ʻana i ka maikaʻi, a hiki ke mālama i ka hoʻopukapuka ʻana i ka waiho ʻana i nā pipeline. Hoʻohana nui ʻia no ka waiho ʻana i nā pipeline e lawe ana i ka aila, ke kinoea maoli, etc.
6. ʻO ka paipu kila i hoʻoheheʻe ʻia i loko o ke ao holoʻokoʻa (SY5037-83). hana ʻia ia e ka lua-ʻaoʻao hoʻoheheʻe arc submerged a i ʻole ka ʻaoʻao hoʻokahi. Hoʻohana ʻia nā paipu kila i hoʻopaʻa ʻia no ka lawe ʻana i nā wai haʻahaʻa haʻahaʻa e like me ka wai, ke kinoea, ka ea, a me ka mahu.
Hiki i nā paipu welded ke ho'ohana i 'ekolu hana ho'ā'o pa'akikī.
