Ma Cangzhou Spiral Steel Pipes Group Co., Ltd., ke haʻaheo nei mākou e hōʻike i kā mākou holomua hou loa i ka ʻoihana paipu kila -Paipu SSAWHoʻohui kēia huahana hou i ka ʻenehana holomua me ka ʻike loea like ʻole e hāʻawi i nā hopena maʻalahi no nā ʻano hana like ʻole.

He paipu SSAWpaipu wili i hoʻopaʻa ʻiahana ʻia mai nā wili kila ʻokiʻoki kiʻekiʻe. Hoʻohana mākou i ka ʻenehana extrusion holomua e hōʻoia i ka mahana mau ma ke kaʻina hana holoʻokoʻa, a laila hana i ka wili ʻākuhi ʻelua ʻaoʻao i lalo o ka wai. Hōʻoia kēia ʻenehana akahele i kahi pilina paʻa a paʻa, e hopena ana i kahi paipu ikaika a hilinaʻi.

ʻO kekahi o nā pōmaikaʻi nui loa opaipu wili i hoʻopaʻa ʻiaʻo kona ikaika kiʻekiʻe, ʻoi aku ka maikaʻi ma mua o ka paipu wili ʻia i hoʻopili pololei ʻia. ʻO kēia ka mea kūpono no nā papahana e pono ai ka hoʻonui ʻia o ke ʻano kūkulu. Eia kekahi, ma muli o kāna kaʻina hana hana kūikawā, hiki ke hana ʻia ka paipu wili ʻia me ka hoʻohana ʻana i nā bila kila haiki, e ʻae ana i ka hana ʻana o nā paipu anawaena nui. Eia kekahi, ma ka hoʻohana ʻana i nā hakahaka o ka laulā like, hiki iā mākou ke hana maʻalahi i nā paipu o nā anawaena like ʻole, e hoʻonui hou ana i kona versatility.

Me ka kūpaʻa ikaika i ka maikaʻi, ua hoʻokomo kā mākou hui i nā kumuwaiwai nui i ka hoʻokumu ʻana i nā hale hana hana kiʻekiʻe loa. Uhi ka hui i kahi ʻāpana o 350,000 mika kuea a he 680 miliona yuan ka huina waiwai. Akā ʻo ka mea e hoʻokaʻawale maoli iā mākou ʻo kā mākou hui i hoʻolaʻa ʻia. ʻO kā mākou poʻe hana o 680 mau loea akamai loa ke kumu hoʻoikaika ma hope o kā mākou holomua.

Ua haʻaheo mākou i kā mākou hiki ke hana i kēlā me kēia makahiki he 400,000 tons o nā paipu kila wili, e ʻoi aku ana ma mua o nā kūlana o ka ʻoihana. Ua hoʻokumu kēia hana i kahi waiwai hana kiʻekiʻe loa o 1.8 biliona yuan. Hōʻoia kā mākou hui akamai e pili ana kēlā me kēia mea hana e haʻalele ana i kā mākou hale i nā ana hoʻomalu maikaʻi loa, e hōʻoiaʻiʻo ana i kā mākou mea kūʻai aku i ka maikaʻi kiʻekiʻe.

I ka hōʻuluʻulu manaʻo, he mea hoʻololi pāʻani nā paipu wili i hoʻopaʻa ʻia i loko o ka ʻākuhi no ka ʻoihana paipu kila. Me kona ikaika kiʻekiʻe, ka versatility kūikawā a me ka hilinaʻi ʻole, ʻo ia ka hopena hope loa no kāu mau koi paipu wili āpau. E hana pū me Cangzhou Spiral Steel Pipes Group Co., Ltd. i kēia lā e ʻike i ka wā e hiki mai ana o ka ʻoihana paipu kila.

Aʻe: Ke hoʻololi nei i ka hoʻokomo ʻana o ka laina wai honua me ka ʻenehana paipu welded helical aunoa
