ʻO Shandong Changshengda kila Co., Ltd he hui kālepa haole o Shandong Liaocheng Jinzheng Steel Pipe Co., Ltd. aia i loko o ke kahua paipu kila maʻemaʻe loa ma Kina, me nā hale hana hana maʻamau. Ua hoʻokumu ʻia ka hui ma 2011 a he "National 863 Plan Project Implementation Unit". He 800 mau limahana ka hui i kēia manawa, me 120 mau limahana waena a me nā limahana loea. Hoʻopili ka hale hana i kahi ʻāpana o 200000 square meters. Ua holomua ka ʻoihana i ka hoʻoheheʻe ʻana, ka hoʻoheheʻe centrifugal, extrusion, a me nā laina hana ʻōwili, a me nā keʻena hana oxygen, nā kikowaena kinoea kūlohelohe, 110KV substations, nā hale mālama wai, a me nā keʻena loiloi kiʻekiʻe kiʻekiʻe a me nā keʻena physics i kūlike me ka mea nui. mea lako. Ua lako me ka holomua ho'āʻo kino a me ka kemika lako, a me ka hou hoʻolauna o nui annealing umu ahi a me ka hana o ka nui waiʻakika holoi mea kanu, Loaʻa iā mākou he kūʻokoʻa kila paipu ho'āʻo keʻena hoʻokolohua a me ka nui-unauna 'akomi kani ultrasonic a me ka eddy manawa ho'āʻo lako, a ke kūkulu nei i kahi ʻoihana hana ʻoihana no ka lawe ʻana i nā mea kila.
Ua loaʻa i ka hui ka ISO9001 quality management system certification a specializes in produce hot-rolled seamless steel pipes with a outside diameter of 10-609.6mm, anu anu huki seamless steel paipu, a me ka pololei olokaa seamless kila paipu; ʻO nā paipu kila ʻole i hana ʻia me nā mea e like me API 5L Astm A53/A106 Gr. B A355, A333, A192/ASTM A210 etc; A aia he 5 mau laina hana ʻōwili wela a me 11 laina hana ʻōwili pololei e hiki ke hana a hana i nā paipu kila maʻemaʻe o nā kikoʻī a me nā mea. ʻO ka hana makahiki o 100000 tons o nā paipu kila ʻole. Hoʻopili mau ka hui i ka ʻoihana ʻoihana "ʻenehana alakaʻi, kiʻekiʻe kiʻekiʻe a me ka pono, ka mea kūʻai mua, a me ka hoʻokō ʻana i nā kānāwai a me nā lula".
