SAW (Longitudinal Submerged Arc Welded) ʻOkoʻa nā paipu mai nā ʻano paipu welded ʻē aʻe i hoʻohana ʻia i nā ʻōnaehana paipu.Hoʻohana nui ʻia lākou i nā pipeline hoʻouna ʻaila a me ka hau,a me nā hana hoʻolālā e like me ke kūkulu ʻana i nā alahaka a me nā tunnels.
Ma nā ʻōlelo o nā maʻamau, ua kūlike nā paipu LSAW i nā kūlana i hoʻonohonoho ʻia e ka American Petroleum Institute (API), ka International Organization for Standardization (ISO), a me ka ʻAmelika.
Ahahui o na Mechanical Engineers (ASME).Hōʻike kēia mau maʻamau i nā kikoʻī no nā ana, ka haku mele, nā waiwai mechanical, a me nā koi hoʻāʻo no nā paipu LSAW.
LSAW paipuloaʻa i nā māka like ʻole e like me ASTM A671, ASTM A672, ASTM A525,BS EN10210,BS EN10219 A MEAPI 5L Gr.B.ʻO ke koho o ka papa e pili ana i ka noinā koi e like me ke kaomi, ka mahana, a me ke ʻano o ka wai e lawe ʻia ana.
He ʻokoʻa ka hoʻohana ʻana i nā paipu LSAW, a ua hoʻohana nui ʻia lākou i nā laina hoʻouna ʻaila a me ke kinoea, nā paipu wai, a me nā noi hana e like me ke kūkulu ʻana i nā alahaka a me nā tunnels.Ua makemake ʻia kēia mau paipuma luna o nā paipu welded ʻē aʻe ke hāʻawi nei lākou i ka pololei o ka dimensional ʻoi aku ka maikaʻi, ka ikaika kiʻekiʻe, a me ka lōʻihi.Hiki ke hana ʻia nā paipu LSAW i nā nui nui a me nā lōʻihi, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i nā pipeline hoʻouna lōʻihi.
I ka hopena, hana koʻikoʻi nā paipu LSAW i ka hoʻouna ʻana i ka aila a me ke kinoea a me nā noi hana.Kūlike lākou i nā kūlana koʻikoʻi, hele mai i nā māka like ʻole, a paʻa a hilinaʻi.
