SSAW Pipe API Spec 5L (PSL2) No ka Paipu Kinoea Maoli
Ma Cangzhou Spiral Steel Pipes Group Co., Ltd., haʻaheo mākou e hōʻike i kā mākou holomua hou loa i ka ʻoihana paipu kila -paipu SSAW.Hoʻohui kēia huahana hou i ka ʻenehana ʻokiʻoki me ka ʻike like ʻole e hāʻawi i nā hāʻina maʻamau no nā ʻano noi.
ʻO ka paipu SSAW hepaipu wiliwili spirali hana ʻia mai nā wili kila kiʻekiʻe.Hoʻohana mākou i ka ʻenehana extrusion kiʻekiʻe e hōʻoia i ka wela maʻamau i loko o ke kaʻina hana holoʻokoʻa, a laila hana i ka hoʻoheheʻe ʻana i nā uea ʻelua ʻaoʻao ʻelua ʻaoʻao submerged arc.Hāʻawi kēia ʻenehana loea i kahi paʻa paʻa a paʻa, e hopena i kahi paipu ikaika a hilinaʻi.

ʻO kekahi o nā pōmaikaʻi nui loa opaipu wiliwili spiralʻO kona ikaika ʻoi aku ka maikaʻi, ʻoi aku ia ma mua o ka paipu wili wili pololei.He mea kūpono kēia no nā papahana e koi ana i ka hoʻomaikaʻi ʻana i ka paʻa.Eia kekahi, ma muli o kāna kaʻina hana kūʻokoʻa, hiki ke hana ʻia ka paipu spiral welded me ka hoʻohana ʻana i nā bilets kila ʻoi aku ka liʻiliʻi, e ʻae ana i ka hana ʻana o nā paipu anawaena nui aʻe.Eia kekahi, ma ka hoʻohana ʻana i nā blanks o ka laulā like, hiki iā mākou ke hana maʻalahi i nā paipu o nā anawaena like ʻole, e hoʻonui hou i kona versatility.
Me ka paʻa paʻa i ka maikaʻi, ua hoʻopuka kā mākou hui i nā kumu waiwai nui i ka hoʻonohonoho ʻana i nā hale hana hou.Hoʻopili ka hui i kahi ʻāpana o 350,000 square square a loaʻa iā ia ka waiwai o 680 miliona yuan.Akā ʻo ka mea e hoʻokaʻawale maoli iā mākou ʻo kā mākou hui hoʻolaʻa.ʻO kā mākou poʻe limahana o 680 mau loea akamai loa ka mea hoʻoikaika ma hope o kā mākou holomua.
Haʻaheo mākou i kā mākou mana hana makahiki o 400,000 tons o nā paipu kila spiral, ʻoi aku ka nui o nā kūlana ʻoihana.Ua hoʻokumu kēia mea hoʻohālikelike ʻole i kahi waiwai hoʻopuka kiʻekiʻe loa o 1.8 biliona yuan.ʻO kā mākou hui ikaika e hōʻoia i kēlā me kēia hāmeʻa e haʻalele ana i kā mākou hale hana e pili ana i nā ana hoʻomalu maikaʻi loa, e hōʻoiaʻiʻo ana i kā mākou mea kūʻai aku i ka maikaʻi.
ʻO ka hōʻuluʻulu manaʻo, he mea hoʻololi pāʻani no ka ʻoihana paipu kila.Me kona ikaika kiʻekiʻe, versatility kūikawā a me ka hilinaʻi like ʻole, ʻo ia ka hopena hope loa no kāu mau koi paipu welded.E hui 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.
