Paipu LSAW(Longitudinal Submerged Arc-Welding Pipe), kapa ʻia hoʻiPaipu SAWL.Lawe ʻo ia i ka pā kila ma ke ʻano he mea maka, hoʻoheheʻe ʻia e ka mīkini hoʻoheheʻe, a laila hana ʻelua ʻaoʻao submerged arc wili.Ma o kēia kaʻina hana e loaʻa ai i ka paipu kila LSAW ka ductility maikaʻi loa, weld paʻakikī, kūlike, plasticity a me ka sila nui.
ʻOi aku ka nui o ke anawaena paipu LSAW ma mua o ERW, maʻamau mai 406mm a 2020mm.ʻO nā hana maikaʻi ma ke kūpaʻa kiʻekiʻe, a me ke kūpaʻa haʻahaʻa haʻahaʻa.
Paipu SSAW(Spiral Submerged Arc-Welding Pipe), kapa ʻia hoʻiPaipu HSAW(Helical SAW), wiliwili laina ʻano like me ka helix.Ke hoʻohana nei ia i ka ʻenehana hoʻoheheʻe like o Submerged Arc-Welding me ka paipu LSAW.ʻOkoʻa ka paipu SSAW i wili ʻia ma kahi o ka LSAW i wili lōʻihi ʻia.ʻO ke kaʻina hana ke ʻōwili nei i ke kaula kila, e hana i ka ʻōwili ʻana i kahi kihi me ke kuhikuhi o ke kikowaena paipu, ka hana ʻana a me ke kuʻi ʻana, no laila aia ka wili kuʻi ma kahi laina spiral.
ʻO ke anawaena paipu SSAW mai ka 219 mm a hiki i ka 2020 mm. ʻO ka mea pōmaikaʻi hiki iā mākou ke loaʻa i ke anawaena like ʻole o nā paipu SSAW me ka nui like o ke kaula kila, aia kahi noi ākea no ka mea kila kila, a me ka wili wili. pono e pale i ke koʻikoʻi koʻikoʻi, nā hana maikaʻi e halihali i ke kaumaha.
