wili welahana ʻia me ka papa hoʻolei hoʻomau a i ʻole ka papa ʻōwili mua e like me ka mea maka, i hoʻomehana ʻia e ka umu hoʻomehana stepper, hoʻoheheʻe ʻia e ka wai kiʻekiʻe, a laila komo i ka wili roughing. ʻOki ʻia ka mea roughing i nā poʻo, huelo, a laila komo i ka wili hoʻopau no ka ʻōwili ʻana i ka kamepiula. Ma hope o ka ʻōwili hope ʻana, hoʻoluʻu ʻia e ke kahe laminar (ka hoʻoluʻu ʻana i ka computer-controlled cooling rate) a wili ʻia e kahi coiler a lilo i wili pololei.
Hiki ke hoʻohana ʻia e hana i nā huahana kila maʻamau, e like me nā ʻāpana kaʻa, nā mea kūkulu hale, a me nā pipeline. Hiki i kēia kaʻina hana ke hana i nā papa kila me ka ikaika kiʻekiʻe, ke kūlana kiʻekiʻe, ke ʻano pololei a me ka nui e hoʻokō i nā pono o nā mākeke ʻoihana a me nā mea kūʻai aku.
Loaʻa nā huahana ʻōwili wela i nā waiwai maikaʻi e like me ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, ka hana maʻalahi a me ka weldability maikaʻi, a no laila ua hoʻohana nui ʻia i nā ʻoihana hana e like me ke kūkulu ʻana, nā mīkini, nā paila, a me nā moku kaomi.
I ke kaʻina hana o nā wili wela, pono mua e hoʻouka i ka billet kila i hoʻomoʻa ʻia i loko o ka umu wela a hoʻohana i ka wela kiʻekiʻe a me ke kaomi ʻana i ka ʻōwili wela i loko o nā wili lahilahi. Hāʻawi ʻia nā ʻōwili i loko o nā mea hoʻoluʻu no ka hoʻoilo wikiwiki a paʻa. ʻO kēia kaʻina hana e hoʻonui i ka ikaika a me ka lōʻihi o ke kila a hiki i ka mana o ka nui a me ke ʻano o ke kila, a laila e hoʻomaikaʻi ai i ka hana a me ka maikaʻi.
Ma hope aʻe, hele ka coil i nā ʻanuʻu hana, me ka hoʻomaʻemaʻe ʻana i ka ʻili, ka ʻoki ʻana, a me ka wili ʻana, i mea e hoʻohuli ai i ka huahana hope. I kēia mau ʻanuʻu, hoʻohana nā limahana hana i nā mea hana holomua a me nā mea hana e hōʻoia ai e hoʻokō kēlā me kēia coil i nā kūlana koʻikoʻi a me nā kikoʻī.

ʻO Tianjin Yuantai International Trading Co., Ltd., ʻo ke kino nui o ka hale hana ʻo Tianjin Yuantai Derun Steel Pipe Manufacturing Group, i hoʻokumu ʻia i ka makahiki 2002, a ʻo kona keʻena nui aia ma Daqiuzhuang Industrial Zone, Tianjin.The hui makahiki hana mana he 10 miliona mau tona, a ʻo ia ka mea hana nui loa o ka ʻeleʻele RW LSAW paipu, paipu paipu ʻeleʻele LSAW, paipu paipu. a me structural paipu i loko o China.Continuously lanakila i ka luna 500 Pākē pilikino 'oihana a me ka luna 500 Chinese manufacturing enterprises.Oi aku mamua o 100 kila hollow cross-section enehana patents, national CNAS keʻena hoʻokolohua hōʻoia.
Loaʻa iā Tianjin Yuantai Group he 65 ʻeleʻele kiʻekiʻe-frequency welded steel pipe production laina, 26 hot-dip galvanized steel pipe process production lines, 10 pre-galvanized steel pipe production lines, 8 photovoltaic bracket production lines, 6 ZMA steel pipe production lines, 3 spiral welded pipe production lines, 2 ZMA steel coil production lines, a me 1 laina hana JCOE.
Ua hala ka hui i ka ISO9001, ISO14001, CE, BV, JIS, DNV, ABS, LEED, BC1 a me nā palapala hōʻoia ʻē aʻe.
Ua lawe ʻia aku nā huahana ʻo Yuantai Derun i nā ʻāina a me nā ʻāina a puni ka honua, a ua komo i nā hana nui ma ka home a me nā ʻāina ʻē i nā manawa he nui, lanakila i ka hoʻomaikaʻi ʻana mai nā mea kūʻai aku.
ʻO nā lako hana kiʻekiʻe, ka ikaika ʻenehana maikaʻi loa, nā talena hoʻokele maikaʻi a me ka ikaika kālā ikaika e hōʻoiaʻiʻo i ka hana huahana maikaʻi loa. Hoʻohana nui ʻia nā huahana ma nā ʻano he nui, e like me ke kūkulu ʻana i ke kila kila, ka hana kaʻa, ka hana moku, ka hana mīkini, ke kūkulu ʻana i ke alahaka, ka hana ʻana o ka ipu hao, ke kūkulu ʻana i ke kahua pāʻani a me ke kūkulu mokulele nui. Ua hoʻohana ʻia nā huahana i nā papahana Kina kaulana e like me ka National Stadium (Bird's Nest), ka National Grand Theatre a me ka Hong Kong-Zhuhai-Macao Bridge.

Hiki ke hoʻokaʻawale ʻia ka ʻike i: haku mele mele, ikaika hua, ikaika tensile, waiwai hopena, etc.
I ka manawa like, hiki i ka hui ke hoʻokō i ka ʻike kīnā ma ka laina a me ka annealing a me nā kaʻina hana wela e like me nā pono o ka mea kūʻai aku.
