Pipa Welded Spiral No nā Paipu Kinoea Kiʻi Hōʻikeʻia

ʻO ka wehewehe pōkole:

Welina mai iā Cangzhou Spiral Steel Pipes Group Co., Ltd. he mea hana nui o Spiral Welded Pipes.Hoʻolaha mākou i ka hāʻawi ʻana i nā paipu kinoea kiʻekiʻe e pāʻani ana, i ka lawe ʻana i ke kinoea mai nā kahua eli a i ʻole nā mea kanu hana i nā kikowaena hoʻolaha kinoea kūloko a i ʻole nā ʻoihana ʻoihana.ʻO kā mākou ʻokiʻokikaʻina hana wili paipua me ka ʻenehana holomua e hōʻoiaʻiʻo i nā paipu kūpono no kāu mau koi holo kinoea.

E hoʻouna i ka leka uila iā mākou
