Ka hoʻomaopopo ʻana i ke koʻikoʻi o ka maikaʻi o ke kinoea kinoea maikaʻi: X42 SSAW Pipe, ASTM A139 a me EN10219
X42SSAWpaipuhe ʻano paipu kinoea kūlohelohe i hoʻohana mau ʻia i ka ʻoihana ʻaila a me ka ʻoihana kinoea.Hana ʻia me ka hoʻohana ʻana i ke kaʻina hana kuʻi ʻana arc i hoʻopuka ʻia i nā paipu kiʻekiʻe a paʻa.ʻO ka paipu X42 SSAW he ikaika kiʻekiʻe a me nā waiwai kemika maikaʻi loa, kūpono ia no nā koi koi o ka lawe kinoea maoli.ʻO kona kūpaʻa maikaʻi loa i ka corrosion a me ka haki ʻana, ʻo ia ke koho mua no nā papahana kūkulu pipeline.
ASTM A139ʻO kekahi kūlana koʻikoʻi no nā paipu kinoea maoli.Hoʻopili kēia kikoʻī i ka electrofusion (arc) welded straight a spiral seam pipe steel i hoʻohana ʻia no ka lawe ʻana i nā kinoea, ka mahu, ka wai a me nā wai ʻē aʻe.ʻIke ʻia ka paipu ASTM A139 no kona hilinaʻi a me ka hana lōʻihi ma lalo o nā kūlana hana ʻoi loa.Hoʻolālā ʻia kēia mau paipu e kū i nā puʻe kiʻekiʻe a me nā loli wela, e hoʻolilo iā lākou i mea kūpono no ka lawe ʻana i ke kinoea kūlohelohe a me nā noi hoʻoili.
