SSAW(ʻike ʻia hoʻi ʻoSAWH) ʻo ka paipu kila e pili ana i ka paipu kila i hoʻopili ʻia me ke arc submerged spiral.
ʻO ke kaʻina hana no kēia ʻano paipu kila e pili ana i ka hoʻomau ʻana i ka ʻoki ʻana i nā papa kila i loko o ke ʻano ʻōwili a me ka hoʻopili ʻana i nā kihi o nā papa ma ka hoʻopili ʻana i ka ʻākuhi arc i loko a me waho e hana i kahi humuhumu wili no ka paipu.
ʻO ke ʻano o kēia ʻano paipu kila he humuhumu weld spiral, a ʻo kona hana pono kiʻekiʻe e kūpono ia no ka hana ʻana i nā paipu kila anawaena nui.
He mea hana a mea hoʻolako paipu kila i hoʻopili ʻia ʻo Botop Steel mai Kina mai, e hāʻawi ana i nā ʻano kūlana like ʻole a me nā nui o ka paipu kila i hiki ke hoʻopilikino ʻia e hoʻokō i kāu mau koi papahana.
ʻO nā huahana paipu kila SSAW hiki iā mākou ke hoʻolako aku me ka paipu kila wili o API 5L, ASTM A252, EN 10217, GB/T 9711, a me nā kūlana ʻē aʻe he nui. Eia kekahi, hāʻawi mākou i nā lawelawe he nui e pili ana i ka hana ʻana i nā paipu kila, ka flanging, nā mea hoʻopili paipu, ka uhi ʻana, ka shot peening, a me nā mea hou aku.
ʻO ka pōmaikaʻi kūikawā o nā paipu SSAW ʻo ia ka hiki ke hana i nā paipu anawaena nui a hiki i ka 3,500 mm, kahi mea hiki ʻole ke hana ʻia me nā ʻano paipu ʻē aʻe.
Eia kekahi, loaʻa i nā paipu SSAW nā pono o ka wikiwiki o ka hana ʻana, ka hiki ke hana i nā paipu i nā lōʻihi pākahi, a me kahi ākea o nā noi.
ʻO ka hana ʻana o ka paipu kila SSAW he hana hana ponoʻī loa ia, ʻaʻole wale ia e hoʻomaikaʻi nui i ka pono o ka hana ʻana o nā paipu kila, akā e hōʻoiaʻiʻo ana hoʻi i ke kūlana kiʻekiʻe o ka huahana.
Ua kapa ʻia ʻo SSAW i kekahi manawaDSAWno ka mea, hana ʻia ke kaʻina hana kuʻihao me ka hoʻohana ʻana i ka ʻenehana kuʻihao arc submerged pālua ʻaoʻao.
