    Nā Paipu Kila ʻōwili wiliwili hoʻohuihui laina paipu

    Kiʻi i hōʻike ʻia no ka hoʻopili ʻana i nā paipu kila wiliwili i hoʻopaʻa ʻia me ka laina paipu
    • Nā Paipu Kila ʻōwili wiliwili hoʻohuihui laina paipu

    Wehewehe Pōkole:

    Welina mai i ka hoʻolauna huahana paipu wiliwili i lawe ʻia iā ʻoe e Cangzhou Spiral Steel Pipe Group Co., Ltd., ka mea hana alakaʻi Kina o nā paipu kila wiliwili a me nā huahana uhi paipu.

    Nā Lepili Huahana

    Ma Cangzhou Spiral Steel Pipe Group Co., Ltd., ʻO kā mākounā paipu humuhumu ʻōwilihe mau huahana kiʻekiʻe e kū ana i nā kūlana ʻoihana kiʻekiʻe loa. Ua hoʻolālā ʻia kā mākou mau paipu no nā ʻano hana like ʻole a ua ʻike ʻia no ko lākou kūpaʻa, ikaika a me ke kūpaʻa ʻana i ka pala.

    ʻO ke kalapona ka mea kumu loa i ke kila a me ke kumu no ka hoʻokaʻawale ʻana i ke kila mai ka hao. Hana ʻia kā mākou mau paipu humuhumu wili mai ke kila kalapona kiʻekiʻe e hōʻoiaʻiʻo ana i ka ikaika a me ke kūpaʻa loa. Me kā lākou ʻike kalapona kiʻekiʻe, kūpono kā mākou mau paipu no nā ʻano hana ʻoihana like ʻole.

    Ma waho aʻe o ke kalapona, aia i loko o kā mākou mau paipu humuhumu spiral nā mea nui ʻē aʻe e like me ka nickel a me ka chromium. He metala ferromagnetic ka nickel e hoʻohui i ka ikaika holoʻokoʻa a me ka polishability o ka paipu. Eia kekahi, kū'ē ia i ka corrosion a hōʻoia i ka lōʻihi o ke ola lawelawe no kā mākou mau paipu. ʻO Chromium, ma ka ʻaoʻao ʻē aʻe, he mea nui ia i ke kila kila a he kūpaʻa maikaʻi loa i ka corrosion. ʻO ka hoʻokomo ʻia ʻana o ka chromium i loko o kā mākou mau paipu humuhumu spiral e hoʻonui hou i ko lākou lōʻihi a me ka hilinaʻi.

    ʻO kekahi o nā pono nui o kā mākou mau paipu humuhumu wiliwili ʻo ia ko lākou hoʻolālā humuhumu ʻole, kahi i hoʻokō ʻia ma o ka ʻenehana wiliwili holomua. ʻO kā mākou ʻenehana wiliwili SAWH (Submerged Arc Spiral Welding) kiʻekiʻe loa e hōʻoia i kahi pilina ikaika a lōʻihi ma waena o nā papa kila paipu. ʻAʻole wale kēia ʻenehana wiliwili e hoʻonui i nā waiwai mechanical o ka paipu, akā e hōʻoia pū i kahi ʻili o loko e laumania, kahi e kūpono ai i ke kahe pono o nā wai a i ʻole nā ​​​​kinoea like ʻole.

    Hoʻohana nui ʻia kā mākou mau paipu humuhumu wili ma nā ʻoihana he nui, me ka ʻaila a me ke kinoea, ka halihali wai, ke kūkulu ʻana a me ka hoʻomohala ʻana i nā pono hana. Hiki ke hoʻokō ʻia ma nā papahana uka a me waho a ma nā ʻōnaehana paipu no nā kumu like ʻole. Me kona kūpaʻa maikaʻi loa i ka pala a me ka ikaika tensile kiʻekiʻe, ʻo kā mākou mau paipu ke koho mua no ka hoʻopili ʻana i nā paipu ma nā wahi ʻino.
