DSAW vs LSAW: nā mea like a me nā ʻokoʻa

ʻO nā ʻano hana kuʻihao maʻamau i hoʻohana ʻia i ka hana ʻana i nā pipeline nui-diameter e lawe ana i nā wai e like me ke kinoea maoli a i ʻole ka aila, ʻo ia ka wili lua ʻaoʻao submerged arc (DSAW) a me ka longitudinal submerged arc welding (LSAW).

ʻO LSAW kekahi o nā ʻano DSAW.
ʻO DSAW kahi acronym no "ʻelua ʻaoʻao submerged arc welding," he huaʻōlelo e hoʻoikaika ana i ka hoʻohana ʻana i kēia ʻenehana.
ʻO LSAW ke kū nei no "Longitudinal Submerged Arc Welding," kahi ʻano i hōʻike ʻia e nā welds e hoʻolōʻihi i ka lōʻihi o ka paipu.
He mea nui e hoʻomaopopo i ka DSAW me nā ʻano paipu SSAW (Spiral Submerged Arc Welding) a me LSAW.

ʻO ka ʻimi ʻana i nā mea like a me nā ʻokoʻa ma waena o DASW a me LSAW he mea hoʻohālikelike ma waena o SSAW a me LSAW.

Nā mea like

ʻenehana welding

Hoʻohana ʻo DSAW a me LSAW i ka ʻenehana lua-ʻaoʻao submerged arc welding (SAW), kahi e hana ʻia ai ka wiliwili ma nā ʻaoʻao ʻelua o ke kila e hoʻomaikaʻi i ka maikaʻi a me ke komo ʻana o ka weld.

Nā noi

Hoʻohana nui ʻia i nā hiʻohiʻona kahi e koi ʻia ai ka ikaika kiʻekiʻe a me ke anawaena nui o nā paipu kila, e like me nā paipu aila a me ke kinoea.

ʻIke ʻia ʻo Weld Seam

Aia kekahi wili weld ko'iko'i ma loko a ma waho o ka paipu kila.

Nā ʻokoʻa

ʻAno weld

DSAW: Hiki ke pololei (weld ma ka lōʻihi o ka paipu) a i ʻole helical (weld i ʻōwili ʻia i ke ʻano helical a puni ke kino o ka paipu), ma muli o ka hoʻohana a me nā kikoʻī o ka paipu.

LSAW: Hiki i ka weld seam ke longitudinal wale nō, kahi e hana ʻia ai ka pā kila i loko o ka paipu a wili ʻia ma kona lōʻihi lōʻihi.

E nānā i nā noi paipu kila

DSAW: No ka mea hiki i ka DSAW ke pololei a i ʻole ka spiral, ʻoi aku ka maikaʻi no kahi ākea o nā kaomi a me nā anawaena like ʻole, ʻoi aku ka nui inā makemake ʻia nā paipu lōʻihi loa ʻoi aku ka kūpono o DSAW.

LSAW: He kūpono loa nā paipu kila LSAW no nā ʻoihana kūlanakauhale a me nā noi kiʻekiʻe e like me ka lawe ʻana i ka wai a me ke kinoea.

Hana Paipu

DSAW: ʻAʻole like ka hana o ka paipu wiliwili ʻia me LSAW ma ke ʻano o ka hoʻomanawanui koʻikoʻi.

LSAW: Ma muli o kāna kaʻina hana paʻa kila me ka hoʻohana ʻana iā JCOE a me nā kaʻina hana hoʻoheheʻe ʻē aʻe, hiki i ka pā paipu kila LSAW ke kū i nā ʻano mīkini like ʻole.

Kumukuai a me ka Hoʻokō pono

DSAW: Ke wili ʻia ka paipu DSAW, ʻoi aku ka maʻalahi a ʻoi aku ka wikiwiki o ka hana ʻana a kūpono no nā paipu lōʻihi.

LSAW: ʻO ka wili wili pololei, ʻoiai e hāʻawi ana i ka maikaʻi kiʻekiʻe, ʻoi aku ka pipiʻi a me ka lohi i ka hana ʻana a kūpono no nā noi me nā koi ʻoi aku ka paʻakikī.

ʻO ke koho ʻana o DSAW a i ʻole LSAW e pili ana i nā koi kikoʻī o ka papahana, me ka waihona kālā, nā koi o ka paipu e kū ai, a me ka paʻakikī o ka hana ʻana a me ka hoʻonohonoho ʻana.ʻO ka hoʻomaopopo ʻana i kēia mau mea like a me nā ʻokoʻa e hiki ke kōkua i ka hoʻoholo kūpono no kahi noi ʻenehana.
