LSAWhe mau pōmaikaʻi nui i ka hana ʻana oanawaena nuia menā paipu kila pā mānoanoaa kūpono loa ia no nā hiʻohiʻona noi kahi e koi nui ʻia ai ka ikaika kiʻekiʻe, ka maikaʻi, a me nā ana pololei.
JCOEhe hana koʻikoʻi loa ia a he hana hōʻike i ka hana ʻana o ka paipu kila LSAW. Loaʻa ka inoa o ke kaʻina hana mai nā ʻanuʻu nui ʻehā i ke kaʻina hana paipu: J-forming, C-forming, O-forming, a me Expanding.
He mea hana a mea hoʻolako paipu kila kalapona kiʻekiʻe mākou mai Kina mai, a he mea kūʻai aku paipu kila seamless hoʻi, e hāʻawi ana iā ʻoe i kahi ākea o nā hoʻonā paipu kila!
Ka Nānā ʻana i nā Mea Hoʻolei
Ka loiloi kemika o nā mea maka paipu kila
Ka waiwai like kalapona kiʻekiʻe loa o S355J0H (CEV): 0.45%.
CEV = C + Mn/6 +(Cr + Mo + V)/5 + (Ni + Cu)/15.
