Hoʻolauna Huahana

ʻO kā mākou lua-ʻaoʻao longitudinal submerged arc welded pipe he mea kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe i hoʻolālā ʻia no nā ʻano hana ʻoihana. Hana ʻia me ka pololei a me ka ʻenehana welding kiʻekiʻe, hāʻawi ia i ka ikaika ʻokoʻa, ka lōʻihi, a me ka hilinaʻi.

Nā mea nui

ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana: ʻO ke kaʻina hana hoʻoheheʻe arc submerged ʻaoʻao ʻelua e hōʻoia i kahi hui kuʻekuʻe a ikaika, e hōʻemi ana i ka hopena o ka leakage a hoʻonui i ka pono holoʻokoʻa o ka paipu.

Ka ikaika kiʻekiʻe: Hana ʻia mai ke kila maikaʻi maikaʻi, hiki i kā mākou paipu ke kū i ke kaomi kiʻekiʻe a me nā ukana kaumaha, e kūpono ana i nā noi koi.

ʻO ka lōʻihi: Me ke kūpaʻa corrosion maikaʻi loa a me ke ola lawelawe lōʻihi, kūpono kēia mau paipu no ka hoʻohana ʻana i nā wahi paʻakikī.

ʻO nā ana kūpono: Mālama mākou i ka mana maikaʻi loa e hōʻoia i ka nui o ka paipu pololei, hoʻomaʻamaʻa maʻalahi i ka hoʻokomo ʻana a hoʻemi i ka pono o nā hoʻololi ma ka pūnaewele.
