ʻO ka ʻokoʻa ma waena o ka paipu ERW a me ka paipu LSAW

ʻO ka paipu ERW a me ka paipu LSAW nā paipu wili wili pololei, i hoʻohana nui ʻia no ka lawe ʻana i ka wai, ʻoi aku ka nui o nā paipu lōʻihi no ka aila a me ke kinoea.ʻO ka ʻokoʻa nui ma waena o nā mea ʻelua ʻo ke kaʻina hana kuʻi.ʻO nā kaʻina hana like ʻole e loaʻa i ka paipu nā ʻano like ʻole a kūpono i nā hiʻohiʻona noiʻi like ʻole.

Ke hoʻohana nei ka paipu ERW i ka wiliwili kūpaʻa kiʻekiʻe a hoʻohana i nā wili kila ākea ākea wela e like me nā mea maka.ʻO kekahi o nā paipu i hoʻohana nui ʻia i kēia lā, ma muli o ka hoʻohana ʻana i nā ʻāpana kila i ʻōwili ʻia me nā ʻano like ʻole a me nā kikoʻī holoʻokoʻa e like me nā mea maka, loaʻa iā ia nā mea maikaʻi o ka pololei kiʻekiʻe, ka mānoanoa pā like ʻole, a me ka maikaʻi o ka ʻili.Loaʻa i ka paipu nā mea maikaʻi o ka wili weld pōkole a me ke kaomi kiʻekiʻe, akā hiki i kēia kaʻina hana ke hana i nā paipu lahilahi ʻiliʻili liʻiliʻi a me ke anawaena (e pili ana i ka nui o ke kaula kila a i ʻole ka pā kila i hoʻohana ʻia e like me ka mea maka).Pili ka weld seam i nā kiko hina, unfused, grooves Corrosion defects.ʻO nā wahi i hoʻohana nui ʻia i kēia manawa ʻo ke kinoea kūloko a me ka lawe ʻana i nā huahana aila.

Hoʻohana ka paipu LSAW i ke kaʻina hoʻoheheʻe arc i hoʻopaʻa ʻia, e hoʻohana ana i hoʻokahi pā waena-mānoanoa e like me ka mea maka, a hana i ka wili kūloko a me waho ma ka wahi kuʻi a hoʻonui i ke anawaena.Ma muli o ka laulā o nā huahana i hoʻopau ʻia me ka hoʻohana ʻana i nā papa kila e like me nā mea maka, ua maikaʻi ka paʻakikī o nā welds, plasticity, uniformity a compactness, a loaʻa nā mea maikaʻi o ke anawaena paipu nui, ka mānoanoa o ka pā paipu, ke kūpaʻa kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa corrosion. .Ke kūkulu ʻana i nā paipu aila lōʻihi a me ke kinoea maikaʻi loa, ʻoi aku ka ikaika kiʻekiʻe, ʻoi aku ka maikaʻi, ʻo ka hapa nui o nā paipu kila i makemake ʻia he mau paipu i hoʻopaʻa ʻia i loko o ka pā pōhaku nui.E like me ka API maʻamau, i loko o ka aila nui a me ke kinoea pipelines, i ka wā e hele ana ma ka Papa 1 a me ka Papa 2 wahi e like me alpine wahi, seabeds, a densely populated wahi kūlanakauhale, pololei seam submerged arc welded paipu wale nō i koho 'ia.
