ʻO JCOE kahi ʻenehana hana paipu no ka hana ʻana i nā paipu kila mānoanoa nui, e pili ana i ka ʻaoʻao ʻelua submerged arc welding kaʻina hana, kahi i wili ʻia ai ka huahana, pre-pepe, piko, seamed, kūloko kūloko, waho welded, straightened, a palahalaha i nā kaʻina hana he nui. Hiki ke hoʻokaʻawale ʻia ke kaʻina hana i nā ʻanuʻu N + 1 (ʻo N ka helu helu maikaʻi), me ka ʻai ʻana o ka pā kila a hoʻopaʻa ʻia me ka transversely i nā ʻanuʻu i hoʻonohonoho ʻia e hoʻokō ai i ka CNC holomua JCO. Hoʻokomo ka pā kila i ka mīkini hana i ka ʻaoʻao transverse, a ke alakaʻi ʻia e ka trolley hānai e hoʻokō i ka pae mua o N / 2 mau ʻanuʻu o ka kuʻi ʻana i nā ʻanuʻu he nui e hoʻokō ai i ka "J" i hana ʻia o ka hapa mua o ka pā kila. ; ka lua o ka pae mua hana i ka "J" i hanaia kila papa wikiwiki transverse hanai i ka transverse i hoakakaia kūlana, mai ka 'ē aʻe hopena o ka unformed kila pā no kekahi N / 2 kapuaʻi o multi-step kulou, e hoʻokō i ka lua o ka hapalua o ke kila. papa hana, e hoʻopau i ka hana "C"; ʻO ka hope, ʻo ka ʻaoʻao haʻahaʻa o ka "C" paipu billet e kulou ana i hoʻokahi manawa e hoʻokō ai "E hoʻokumu ʻia kēlā me kēia ʻanuʻu o ka paʻi ma ke kumu kumu o ka piko ʻekolu.
LSAW paipu kilapāʻani nui i ka nuilsaw laina paipunā papahana, nā papahana hoʻoili wai a me ke kinoea, ke kūkulu ʻana i ka ʻupena pipeline kūlanakauhale, ka hoʻopili ʻana i ke alahaka, ke kūkulu ʻana i ke kūlanakauhale a me ke kūkulu kūlanakauhale. I kēia mau makahiki i hala iho nei, ma ke ʻano he ʻano hou o ka ʻōnaehana hoʻōla ʻana i ka ikehu a me ka ʻōnaehana pili kaiapuni, ua mahalo ʻia ka hale kūkulu kila ma ke ʻano he "hale ʻōmaʻomaʻo" o ke kenekulia 21. I loko o nā papahana hoʻolālā hale kiʻekiʻe a nui loa e hāʻawi i ka mea nui i ka hoʻohana ʻana i ke kila a i ʻole ka ʻōnaehana paʻa paʻa, nā hale ākea nui e hoʻohana ikaika ana i ka hoʻolālā mānoanoa, ʻekolu-dimensional truss structure, cable membrane structure. a me ka pre-stressed structural nenoaiu, keia mau mea kila paipu i loko o ke kūkulu 'ana i oi noi hiʻona, a me ka nui-anawaena, ultra-mānoanoa-pā kila paipu koi ua mahuahua nui.lsaw a me hsaw paipuhana ʻia e Yuantai Derun Steel Pipe Manufacturing Group e hoʻohana nui ʻia. Ma ke ʻano kiʻekiʻemea hana paipu lsawma Kina, ua komo ʻo Yuantai Derun i ka hoʻolako ʻana i nā paipu kila no nā hana nui he nui.
I kēia mau lā, ua hala ʻo Tianjin Yuantai Derun Steel Pipe Manufacturing Group i ka palapala hōʻoia e pili ana iAPI 5L lsaw paipu, a e hoʻohana nui ʻia ma nā ʻano āpau i ka wā e hiki mai analsaw paipu kila kalapona, paipu kila lsaw anawaena nui, alsaw paipu kila welded.
Hiki i ka hui JCOEΦ1420 o Tianjin Yuantai Derun Steel Pipe Manufacturing Group ke hana i nā kikoʻī mai ka Φ355.6mm a i ka Φ1420mm i ke anawaena a hiki i ka 50mm i ka mānoanoa o ka pā, e hoʻopiha ai i ke āpau i ka mākeke ʻo Tianjin no ia mau huahana i ka wā e hana ʻia ai. hiki ke hoʻopōkole loa i ka manawa alakaʻi no ke kauoha ʻana i ka nui o ka nui, ʻo ka ʻeleʻele mānoanoa-pā a puni paipu rectangular. Hiki ke hoʻohana pono ʻia ka paipu wiliwili lōʻihi ʻelua ʻaoʻao no ka hoʻouna ʻana i ka aila a me ke kinoea, ua hoʻohana nui ʻia ka paipu kila JCOE i ka papahana "West-East gas transmission" o ke aupuni, ʻoiai e like me ka paipu kila e hiki ke hoʻopili ʻia. ʻO ke kūkulu ʻana i ke kila kila ultra-high-rise, ma waho aʻe o ka hoʻohana ʻana i ke kaʻina hana "round to square" hiki ke hana ʻia i ke anawaena oversized Eia kekahi, hiki ke hana ʻia ke kaʻina hana "round to square". ʻO nā paipu kila ʻoi loa ka mānoanoa nui, hiki ke hoʻohana ʻia i nā keʻena leʻaleʻa nui a me nā mīkini kaumaha a me nā mea hana.
