Ma nā kahua o ka halihali ʻaila a me ke kinoea, nā paipu hoʻolako wai, a me nā kahua pou kūkulu, he kūlana koʻikoʻi ko nā paipu i hoʻopaʻa ʻia i ka wili ma muli o ko lākou ikaika a me ka hoʻokele waiwai. No nā mea kūʻai mai i nā papahana ʻenekinia, ʻo nā huaʻōlelo "Paipu Welded Spiral API 5L" a me "Paipu Huina Helical API 5L"ʻike pinepine ʻia me ke ʻano like ʻole. No laila, he aha ka pilina ma waena o nā mea ʻelua, a pehea e hoʻomaopopo ʻia ai ko lākou mau manaʻo loea?
ʻO kaʻoiaʻiʻo, ʻo API 5L no ka Spirally Welded Tube a me API 5L no ka Helical Seam Pipe e wehewehe ana i ʻelua mau manaʻo inoa like ʻole o ka huahana like. Hoʻoikaika ka mea mua i ke kaʻina hana "spiral welding", ʻoiai ʻo ka mea hope e hōʻike ana i ka hiʻohiʻona kūkulu o nā "spiral seams". Pili nā mea ʻelua i nā paipu kila ikaika kiʻekiʻe i hana ʻia mai nā ʻāpana kila a i ʻole nā ʻōwili, i kūlou ʻia a ʻōwili ʻia i loko o kahi pōʻai, a laila hoʻohui pū ʻia ma nā humuhumu ma o nā kaʻina hana e like me ka submerged arc welding. ʻO nā ʻano hana welding like ʻole - ʻoi aku ka hana submerged arc welding ʻelua ʻaoʻao - e hōʻoia i ka ikaika a me ke kūpaʻa o ke kino paipu ma lalo o nā kūlana halihali kiʻekiʻe.
ʻO nā paipu wiliwili i hoʻopaʻa ʻia e kūlike me nā kūlana API 5L he pono ko lākou no ka hiki ke hana maʻalahi i nā kikoʻī nui, a hiki ke hoʻopilikino ʻia ka lōʻihi o kēlā me kēia paipu e like me nā koi o ka papahana. Hoʻemi nui kēia i ka nui o nā hui wiliwili ma kahi a hoʻomaikaʻi i ka pono o ke kau ʻana i nā paipu. Inā he Spirally Welded Tube API 5L a i ʻole Helical Seam Pipe API 5L, aia ko lākou waiwai nui i ka hāʻawi ʻana i kahi hopena palekana, hoʻokele waiwai, a hilinaʻi hoʻi no nā paipu lawe lōʻihi.
ʻO Cangzhou Spiral Steel Pipe Group Co., Ltd. kahi mea hana alakaʻi i ke kahua o nā paipu kila wili a me ka uhi ʻana i nā paipu no ka pale ʻana i ka pala ma Kina. Aia ka hale hana ma ke kūlanakauhale ʻo Cangzhou, ma ka moku ʻo Hebei. Mai kona hoʻokumu ʻia ʻana i ka makahiki 1993, ua hoʻonui ka ʻoihana i kona wahi i 350,000 mika kuea, me ka huina waiwai o 680 miliona yuan a me 680 mau limahana. Hana ka hui i 400,000 tons o nā paipu kila wili i kēlā me kēia makahiki, me ka waiwai hana makahiki o 1.8 biliona yuan. Hoʻohana nui ʻia kāna huahana i nā papahana hoʻomohala ikehu nui ma ka home a ma waho.
ʻO ke koho ʻana iā Cangzhou Spiral Steel Pipe Group ʻo ia hoʻi ke koho ʻana i kahi kahua loea o nā makahiki he 30 i hoʻolaʻa ʻia no ka maikaʻi. Inā makemake ʻoe e ʻike hou aku e pili ana i nā palena kikoʻī o Spirally Welded Tube API 5L a me Helical Seam Pipe API 5L, e ʻoluʻolu e nīnau i kēlā me kēia manawa.
