LSAW paipu kilaʻO ia ka ʻōlelo ʻoihana o Longitudinally Submerged Arc Welding.Loaʻa iā ia nā hiʻohiʻona.ʻO ka mea mua, uhi ka kikoʻī huahana i kahi ākea nui.ʻAʻole hiki iā ia ke hana wale i nā paipu me ka liʻiliʻi liʻiliʻi a me ka mānoanoa pā nui akā ʻo nā huahana pū kekahi me ke anawaena nui a me ka mānoanoa pā nui.ʻO ka lua, hiki iā ia ke pale i ka corrosion a me ka haki.Loaʻa iā ia ka nui pololei ʻoi aʻe a maʻalahi hoʻi no ka hana kuʻi ʻana ma ka pūnaewele.ʻO ke kolu, mahalo i ke kaʻina hana hoʻoheheʻe maikaʻi, hiki ke loaʻa ke kaʻina hana kuʻihao paʻa a me ke kūlana kiʻekiʻe.ʻO ka mea hope akā ʻaʻole ka mea liʻiliʻi loa, he maʻalahi ke ʻike i ka ʻike kīnā nondestructive i ke kaʻina hana kuʻi.Ma muli o kēia mau pōmaikaʻi a me kāna mau hiʻohiʻona ponoʻī, ʻo LSAW steel pipe ka manaʻo maikaʻi a ʻoi aku ka nui o nā mea kūʻai aku e makemake e hoʻohana ia no nā hana o kēlā me kēia lā.E like me ka API maʻamau, i loko o ka nui o ka aila a me ke kinoea hoʻouna pipelines, welded kila paipu wale nō i koho 'ia ka paipu i ka wa e hele ai ka paipu ma ka alpine āpana, kai a me ke kulanakauhale populated wahi.

Mai ka hoʻolauna maʻalahi o ka paipu kila LSAW, e hāʻawi ka ʻatikala i kahi ʻōlelo kikoʻī e pili ana i ka manaʻo o nā mākeke paipu kila LSAW ma ka home a ma waho.A hiki i kēia manawa, ke piʻi nui nei ka mākeke paipu kila LSAW ma muli o ka hoʻonui ʻana o ka mana LSAW Kina.Ma waena o kēlā mau mea hana LSAW, makemake kekahi o lākou e kūʻai i nā paipu hoʻoheheʻe mai ke komohana aʻo nā mea hana nui ʻē aʻe e makemake e kiʻi i ka pipe sourcing mai nā mea hana mea kanu kūloko.Ma waho aʻe o Kina, ʻo India a me Middle East ka piʻi ʻana o ka mana LSAW.Ua lilo ʻo Kina i ʻāina nui loa no ka hana ʻana i ka paipu kila LSAW.I ke komo ʻana i ka makahiki 2014, manaʻo ʻia nā pono hou aʻe i ka paipu kila LSAW.E lawe kākou iā Kina i laʻana.Ma waho aʻe o nā koi ʻē aʻe, ua koi ikaika ʻo Kina i loko o kēia ʻano no ka hoʻonui ʻana i ka lōʻihi o ka pipeline gas.

Eia nō naʻe, ke manaʻo nei e piʻi mau ke koi o ka paipu kila LSAW.ʻOiai ʻo ka ʻoiaʻiʻo, ʻo ka mākeke paipu kila welded e ʻeha paha i ka pahū nui.Ma mua, LSAW kila paipu makeke ua hoomaluia e ka Europa a me Iapana Manufacturers akā i ka wā e hiki mai, e halawai me ka ikaika hoʻokūkū mai India a me Kina.Eia nō naʻe, ʻoiai ʻo Kina ka ʻāina nui loa e hana i ka paipu kila LSAW, ʻaʻole e hoʻokō nā koi me ka hiki.

I ka hōʻuluʻulu ʻana, ʻoiai ʻo ka paipu kila LSAW e loaʻa i kekahi mau pilikia liʻiliʻi i ke kaʻina hana hoʻomohala, e hauʻoli mau ana ia i kahi manaʻo maikaʻi a olakino mai ka wā lōʻihi.Pono nā mea kūʻai a me nā mea hana e hilinaʻi me ka manaʻo o ka paipu kila LSAW.
