Nā Paipu Welded Anawaena Nui o ka Spiral Seam
Wehewehe Huahana:
Hana ʻia kā mākou mau paipu wiliwili humuhumu ma ka ʻōwili ʻana i ke kila kila kalapona haʻahaʻa a i ʻole ke kila kila alloy haʻahaʻa i loko o nā ʻāpana paipu ma kahi kihi helix kikoʻī, i kapa ʻia ʻo ke kihi hoʻokumu. A laila humuhumu pono ʻia nā humuhumu paipu e hana i kahi huahana paʻa a hilinaʻi hoʻi. ʻO kekahi o nā hiʻohiʻona ʻokoʻa o kā mākou paipu wiliwili humuhumu ʻo ia kona hiki ke hana ʻia mai nā ʻāpana kila haiki e hana i nā paipu wiliwili nui.
Kēia mau meanā paipu i hoʻopaʻa ʻia me ke anawaena nuihe ākea nā noi, ʻoi aku hoʻi i lokolaina ʻauwaiHāʻawi kā mākou paipu wiliwili i hoʻopaʻa ʻia i ka ikaika kiʻekiʻe a me ke kūpaʻa i ka pala, e kūpono ana no nā ʻōnaehana ʻauwai e pono ai kahi hopena lōʻihi a maikaʻi hoʻi. Inā he hoʻokuʻu ʻana i ka wai ʻino o ke kūlanakauhale a i ʻole ka hoʻokele wai ʻino o nā ʻoihana, hāʻawi kā mākou mau paipu i ke kākoʻo kūkulu a me ke kūpaʻa e pono ai.

Ma Cangzhou Spiral Steel Pipe Group Co., Ltd., maopopo iā mākou ke koʻikoʻi o ka hoʻolako ʻana i nā huahana e hoʻokō ana i nā kūlana kiʻekiʻe loa. Hoʻopili kā mākou kaʻina hana i nā ana hoʻomalu maikaʻi e hōʻoia i kēlā me kēia paipu wili wili a mākou e hana ai he ʻano maikaʻi loa. Hoʻohana mākou i ka ʻenehana a me nā mīkini holomua e hōʻoia i nā ana pololei, nā ʻili laumania a me nā waiwai mechanical kūlike.
Ma ke ʻano he mea hana alakaʻi ʻoihana, ua lako kā mākou hui me nā pono hana hou loa a me kahi hui o 680 mau limahana i hoʻolaʻa ʻia. Uhi ka hui i kahi ʻāpana o 350,000 mika kuea, me ka hana makahiki o 400,000 tons o nā paipu kila wili a me ka waiwai hana o 1.8 biliona yuan. ʻO kā mākou kūpaʻa i ka hoʻomaikaʻi mau a me ka hana hou ua kōkua iā mākou e kūkulu i kahi inoa no ka maikaʻi a me ka hilinaʻi.
I ka hopena:
I ka hōʻuluʻulu manaʻo, ua haʻaheo ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd. e hāʻawi i nā paipu wili wili kiʻekiʻe. Hana ʻia mai ke kila palupalu a i ʻole ke kila alloy haʻahaʻa, hana ʻia kā mākou mau paipu me ka pololei a me ka ʻike loea. He kūpono loa kā mākou mau paipu wili nui no nā noi sewer ma muli o ko lākou hiki ke hana ʻia mai nā ʻāpana kila haiki. E koho iā Cangzhou Spiral Steel Pipe Group Co., Ltd. e hāʻawi i nā hopena paʻa, kūpono a hilinaʻi hoʻi no kāu mau pono paipu.
