LONGMA GROUP Pololei Seam Welded Paipu
Ua hoʻopaʻa ʻo LONGMA GROUP i kona kūlana ma ke alo o ka ʻoihana no ka hana ʻana i ka corrosion-resistant paipu wiliwili wili pololei. Hoʻokō a ʻoi paha kā lākou laina huahana nui i nā kūlana honua e like me API 5L, ASTM A53, ASTM A500, ASTM A252, a me ASTM A795. Hoʻohana ka hui i nā kaʻina hana ʻokiʻoki e like me ERW, LSAW, a me SSAW e hana i nā paipu me nā anawaena o waho mai ka 4 iniha a 56 iniha. Hoʻohana ʻia nā ʻōnaehana hoʻokele kūlana kiʻekiʻe a me nā mea hoʻāʻo i kā lākou mau hale hana e hōʻoia i ka kūlike o ka huahana a me ka pale ʻana i ka corrosion.
Hōʻike ʻia ka hoʻolaʻa ʻana o LONGMA GROUP i ka pale ʻana i ka corrosion e kāna mau mea hoʻonaninani maʻalahi a me nā mea hiki ke mālama i ka ʻili. Hoʻohui lākou i nā ʻenehana hou i ka pale anti-corrosion i loko o kā lākou ʻōnaehana hoʻopili, e like me FBE, 3LPE, a me nā linings kūloko kūikawā. Hoʻopili ʻia kēlā me kēia paipu i ka hoʻāʻo a me ka nānā ʻana e hōʻoia i ka pono o ka uhi ʻana a me ka hoʻokō ʻana i nā koi kikoʻī. Mālama ka ʻoihana i nā palapala kikoʻī o nā waiwai waiwai, nā noi uhi, a me nā hopena hōʻike, e hōʻoiaʻiʻo ana i ka traceability holoʻokoʻa i ke kaʻina hana.
Ma waho aʻe o ka hana ʻana, ua hoʻopili ʻia ka ʻike loea o LONGMA GROUP i nā lawelawe kākoʻo mea kūʻai. Hāʻawi kā lākou hui ʻenekinia i nā ʻōlelo aʻo kikoʻī e pili ana i ke koho ʻana i nā mea, nā kikoʻī o ka uhi ʻana, a me nā pono mālama e pili ana i nā kūlana noi kikoʻī. Hiki i nā hui e pono ai nā hoʻonā paipu kūpaʻa hiki ke hilinaʻi iā LONGMA GROUP ma info@longma-group.com no ka ʻōlelo aʻoaʻo loea a me ka ʻike huahana. ʻO ka hoʻolaʻa ʻana o ka ʻoihana i ka maikaʻi a me ka lawelawe mea kūʻai aku ua hoʻopaʻa i kona inoa ma ke ʻano he hoa hilinaʻi i ka hāʻawi ʻana i nā hopena pipeline lōʻihi no nā noi paʻakikī.
