Nā paipu welded longitudinalhe mea koʻikoʻi i loko o kekahi mau ʻoihana e like me ke kūkulu ʻana, ka aila a me ke kinoea, a me nā papahana waho. Ma waena o nā ʻano like ʻole i loaʻa i ka mākeke, kaulana nā paipu kila kalapona LSAW (Longitudinal Submerged Arc Welded) ma muli o ko lākou ʻano maikaʻi. Hana ʻia maiAPI 5L kila,ʻO kēia mau paipu he lōʻihi loa a kūpono no ka nui o nā noi.
ʻO kekahi o nā pono nui olongitudinal submerged arc welded carbon steel pipeʻo kona ikaika a ʻoʻoleʻa. ʻO ke kaʻina hana wili lōʻihi e hōʻoiaʻiʻo i ka weld mau a me ka ikaika, e hiki ai i ka paipu ke kū i nā kūlana kiʻekiʻe. Hoʻohui hou, ʻo ka hoʻohana ʻana i ke kila API 5L e hoʻomaikaʻi hou i kāna mau waiwai mechanical, e kūpono ai i nā kaiapuni paʻakikī. Loaʻa i kēia mau paipu ka ikaika tensile kiʻekiʻe a me ke kūpaʻa corrosion maikaʻi loa, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana lōʻihi i nā kūlana paʻakikī.
ʻO kā mākou hui nui nā kūlana: API 5L PSL1 a me PSL2. ASTM A252,BS EN10210, BS EN10219. Welina mai i nā kelepona kūʻai, nā kūkākūkā pāʻoihana kamaʻilio.
