SSAW(ʻike pū ʻia ʻoSAWH) paipu kila e pili ana i ka wiliwili wiliwili wiliwili i hoʻopaʻa ʻia arc wiliwili ʻia.
ʻO ke kaʻina hana no kēia ʻano paipu kila, ʻo ia ka ʻoki mau ʻana i nā pā kila i loko o ke ʻano spiral a hoʻopaʻa pū ʻia nā ʻaoʻao o nā pā e ka wili arc submerged arc i loko a me waho e hana ai i kahi wili wiliwili spiral no ka paipu.
Hōʻike ʻia kēia ʻano paipu kila ma ka loaʻa ʻana o kahi wili weld spiral, a ʻo kāna hana kiʻekiʻe e kūpono ai no ka hana ʻana i nā paipu kila nui.
ʻO Botop Steel he mea hana a me ka mea hoʻolako mai Kina, e hāʻawi ana i ka nui o nā kūlana a me nā nui o ka paipu kila e hiki ke hoʻololiʻia e kūpono i kāu mau koi papahana.
ʻO nā huahana paipu kila SSAW hiki iā mākou ke hoʻolako pū me ka paipu kila spiral o API 5L, ASTM A252, EN 10217, GB/T 9711, a me nā kūlana ʻē aʻe he nui.Eia kekahi, ke hāʻawi nei mākou i nā lawelawe he nui e like me ka hoʻoili ʻana i ka paipu kila, ka flanging, nā paipu paipu, ka uhi ʻana, ka peening pana, a me nā mea hou aku.
ʻO ka pōmaikaʻi kūʻokoʻa o nā paipu SSAW ka hiki ke hana i nā paipu nui-diameter a hiki i 3,500 mm, ʻaʻole hiki ke hiki me nā ʻano paipu ʻē aʻe.
Ma waho aʻe o kēia, loaʻa i nā paipu SSAW nā pōmaikaʻi o ka wikiwiki o ka hana wikiwiki, ka hiki ke hana i nā paipu i nā lōʻihi lōʻihi o kēlā me kēia kanaka, a me kahi ākea o nā noi.
ʻO ka hanaʻana o ka paipu kila SSAW he hana maʻalahi loa ia,ʻaʻole wale i ka hoʻomaikaʻi nuiʻana i ka maikaʻi o ka hana paipu kila, akā e hōʻoiaʻiʻo ana i ke kūlana kiʻekiʻe o ka huahana.
Ua kapa ʻia ʻo SSAW i kekahi manawaDSAWno ka mea, ua hana ʻia ke kaʻina hana kuʻi me ka hoʻohana ʻana i ka ʻenehana welding arc submerged ʻaoʻao ʻelua.
