Introduction to square tube (round to square) kaʻina
ʻO ka hui ʻo Tianjin Yuantai DerunJCOE Φ 1420Hiki i ka ʻāpana ke hoʻopuka i nā kikoʻī a me ka caliberΦ 406mm to Φ 1420mm, me ka mānoanoa o ka paia o 50mm.Ma hope o ka hoʻokomoʻiaʻana i loko o ka hanaʻana, e hoʻopau ia i ka hakahaka ma ka mākeke Tianjin o ia mau huahana, hiki ke hoʻopōkole i ka manawa kauoha o ke anawaena nui loa, nā paipu poʻe a me nā huahana pahu pahu.Hiki ke hoʻohana pono ʻia ka paipu wili pololei ʻelua ʻaoʻao no ka lawe ʻana i ka aila a me ke kinoea.JCOE paipu kilaua hoʻohana nui ʻia i ka papahana "West-East Gas Transmission" aupuni.I ka manawa like, hiki ke hoʻohana ʻia e like mepaipu kila kūkului ke kūkulu ʻana i nā papahana kila kila kiʻekiʻe.Eia kekahi, ʻo ka "poepoe a huinaha"Hiki ke hoʻohana ʻia ke kaʻina hana i loko o ke anawaena nui loa, ka paipu kila rectangular paia mānoanoa, hiki ke hoʻohana ʻia ma ke kahua o nā keʻena leʻaleʻa nui a me ka hana ʻana i nā mea hana mīkini kaumaha.
ʻO ka "poepoe a huinaha"ʻĀpana i hoʻomohala kūʻokoʻa e Tianjin Yuantai Derun Group ka hiki ke hana i ke anawaena kiʻekiʻe o 1000mm × 1000mm square tube, 800mm × ʻO ka mana hana o 1200mm rectangular tube me ka mānoanoa o ka paia o 50mm a me ke anawaena nui a me ka pā mānoanoa. Ua hoʻolako maikaʻi ʻia ka pahu rectangular i ka mākeke kūloko a hiki i 900mm × 900mm × 46mm, puka puka max 800mm × 800mm × 36mm ultra-nui ana a me nā huahana pā ultra-mānoanoa e hoʻokō i nā ʻano koi ʻenehana paʻakikī o nā mea hoʻohana kūloko a me nā haole. 400mm rectangular tube × 900mm × 30mm huahana no hoi i ke alakaʻi pae o "ka puni i ka huinahalike" enehana ma ka home a ma waho.
ʻO ke kolu o ka hale kiʻekiʻe loa ma ka honua - ʻo ka skyscraper kiʻekiʻe kiʻekiʻe ma Wuhan, Kina me ke kiʻekiʻe hoʻolālā o 636 mika - ʻo Wuhan Greenland Center kahi papahana ʻelele o ka hale kila kiʻekiʻe i hoʻolako ʻia e Tianjin Yuantai Derun Group.
Ma hope o nā makahiki o ka hoʻomaikaʻi ʻana i ke kaʻina hana, ua lanakila ka ʻaoʻao o waho o ka ʻāpana ʻāpana nui o ka paia ultra-thick rectangular tube i hana ʻia e ke kaʻina "poe-a-square" o Tianjin Yuantai Derun Group i lanakila lanakila i nā hemahema i hiki ke haki i ka wā o ka pōʻai. ʻO ke kaʻina hana kulou i ka square a me nā pilikia i ka mālama ʻana i ka palahalaha o ka ʻili o ka paipu i ka wā o ke kaʻina "deformation", hiki ke hoʻokō i nā koi o nā kūlana kūloko a me nā ʻāina ʻē no ka huahana a me nā koi o ka mea kūʻai aku.Ua hoʻomaikaʻi nui ʻia ka huahana i nā hana ʻenehana nui i lawe ʻia i ka Middle East, ma Kina, hiki iā ia ke hoʻololi maoli i nā huahana "koluma pahu" i loko o nā ʻoihana hale kila i hui pū ʻia.No ka mea, hoʻokahi wale nō weld nā huahana paipu square, ʻoi aku ka maikaʻi o kona kūpaʻa ʻana ma mua o nā huahana "koluma pahu" i wili ʻia mai nā papa kila me nā welds ʻehā.Hiki ke ʻike ʻia kēia ma nā koi a Party A i kuhikuhi i ka hoʻohana ʻana i ka "square tube" a pāpā i ka hoʻohana ʻana i ka "koluma pahu" ma kekahi mau papahana nui o nā ʻāina ʻē.
Ma ke ʻano o ka ʻenehana hoʻoheheʻe ʻana i ke anuanu, ʻo Tianjin Yuantai Derun Group kahi kokoke i 20 mau makahiki o ka hōʻiliʻili ʻana a loaʻa iā ia ka hiki ke hana i nā paipu kila kila kūikawā e like me nā koi o ka mea kūʻai aku.Hōʻike ke kiʻi i ka "paipu kila octagonal" i hana ʻia e kahi pā leʻaleʻa nui ma Kina.Ma muli o nā palena hoʻolālā, pono e hoʻokumu ʻia ke anu i ka manawa hoʻokahi.Ma muli o nā koi o ke anawaena a me ka mānoanoa o ka paia o ka huahana, ua nīnau nā mea hana nui ma Kina e pili ana iā ia ma mua o ʻekolu mahina.ʻO ka mea hope loa, ʻo Tianjin Yuantai Derun Group wale nō e hiki ke hoʻokō i kāna mau koi like ʻole, a hana maikaʻi ʻia ma kahi o 3000 tons e hoʻopau i nā lawelawe lako a pau o ka papahana wale nō.
ʻO ka lawe ʻana i ke ala "hoʻopilikino" e kū pono ana i ka mākeke ʻo ia ka hoʻolālā kūʻai paʻa o Tianjin Yuantai Derun Group.No kēia kumu, ʻo Tianjin Yuantai Derun Group, me ka pahuhopu hope loa o "nā huahana pahu huinaha a pau ʻo Yuantai e hiki ke hana", koi i ka hoʻopukapuka ʻana ma mua o 50 miliona yuan i ka makahiki i ka noiʻi a me ka hoʻomohala ʻana i nā lako hou, nā molds hou a me nā mea hou. kaʻina hana.I kēia manawa, ua hoʻolauna ʻo ia i nā mea hana hoʻonaninani akamai, hiki ke hoʻohana ʻia e hana i ka ʻāpana o waho arc rectangular square tube no ka ʻenehana pale aniani, a hiki ke hoʻohana ʻia no ka annealing stress relief a i ʻole ka wela wela o ka pahu square, hoʻomaikaʻi nui i ka hiki ke hana. a me ka laulā o nā huahana i hiki ke hana, a hiki ke hoʻokō i nā mea kūʻai aku 'hoʻokahi-kū kūʻai pono no ka structural kila paipu.
AʻIke mākou a pau, hoʻohana nui ʻia ke kolamu pahu i nā hale kūkulu kila nui ma ka home a ma waho, a ua kaulana ia no nā makahiki he nui ma waho.I kēia mau lā, ʻoi aku ka nui o nā hale kūkulu a me nā mea hoʻolālā hoʻohanapaipu huinaha nuima kahi o ke kolamu pahu pahu.Me ka mānoanoa o ka mua, e uhi piha ia i ka hoʻohana ʻana i ke kolamu pahu home i ka wā e hiki mai ana.
I kēia manawa,paipu huinahalike nuiua hoʻokuʻu ʻia i loko o ka paipu square ma ke kaʻina hana kuʻi ʻana arc me nā lako kūikawā.ʻO ka welding arc submerged kekahi o nā kaʻina hana wiliwili me ka hana kiʻekiʻe.ʻO kona inoa piha ʻo ia ka wiliwili arc submerged arc, ʻike ʻia hoʻi ʻo ka welding arc automatic ma lalo o ka papa flux.ʻO ka puʻupuʻu poepoe i hana ʻia e kēia kaʻina hana nā pono penei:
1.Hana kiʻekiʻe
Ma ka ʻaoʻao hoʻokahi, ua pōkole ka lōʻihi conductive o ka uea welding, a ua hoʻonui ʻia ka nui o kēia manawa a me ka nui o kēia manawa, no laila e hoʻomaikaʻi maikaʻi ʻia ke komo ʻana o ke arc a me ka hoʻopaʻa ʻana i ka uaea welding （ Ma kekahi ʻaoʻao, ma muli o ka hopena insulation wela o ka flux a slag, ʻaʻohe kumu hoʻoheheʻe wela ma ka arc, a ʻoi aku ka liʻiliʻi o ka spatter.ʻOiai ua hoʻonui ʻia ka lilo o ka wela no ka hoʻoheheʻe ʻana, ua hoʻonui nui ʻia ka nui o ka hana wela.
2.Kiʻekiʻe weld maikaʻi
Hiki ke mālama paʻa ʻia nā ʻāpana kuʻihao e ka hoʻoponopono ʻakomi.ʻAʻole kiʻekiʻe nā koi no ka pae ʻenehana welder.Paʻa ka hui weld a maikaʻi nā waiwai mechanical.
3.Kūlana hana maikaʻi
Ma waho aʻe o ka hoʻohaʻahaʻa ʻana i ka ikaika hana o ka hana kuʻi lima lima, ʻaʻohe ona arc radiation, ʻo ia ka pono kūʻokoʻa o ka kuʻihao arc submerged.
4.ʻO ke kumukūʻai hana haʻahaʻa
ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke kolamu pahu e like me 1000 a 2000 yuan, ʻoiai ʻo ke kumukūʻai o ka hoʻoili ʻana o ka pahu rectangular nui he mau haneli yuan wale nō, ʻoi aku ka maikaʻi.
5.ʻOi aku ka palekana e hoʻohana
Hoʻohālikelike ʻia me nā mea ʻelua, ka nui o ka weldingpaipu hāhāhāʻoi aku ka liʻiliʻi ma mua o ke kolamu pahu, a ua hoʻemi nui ʻia ka nui o ka wili.
(e laʻa: ka ʻāina hou o Guangdong, Hong Kong a me Macao, ka 128 mika kiʻekiʻe ʻo Ferris huila "Shenzhen light" ma Shenzhen, nā kolamu nui o Google hale keʻena hou ma Singapore, etc. ua hoʻoponopono hou ʻia mai ka hale hana.)
