Ko nga waro waro teitei SAW te waea whakapiringa F7A/P4-ECG me te hangai i nga mahi whakapiringa rerenga rere
Ka whakamahia mo te -40C te paanga o te taiao e hiahiatia ana, i te nuinga o te waa ka whakamahia mo te maimoatanga wera i raro i te waa o nga oko pehanga, nga pipeline me etahi atu hononga.
He aha nga ahuatanga?
●Ko te matua o te paura whakarewa kua rukuhia te waea whakarewa pewa o te 480MPa te karaehe teitei o te rino ka paiherea ki te rere GXL-121. He pumau te mura o te pewa, he ngawari te tango i te para, he ataahua te hanga o te paahi.
●He pai rawa nga ahuatanga miihini o te whakarewa whakarewa, he iti te ihirangi o te P me te S, me te pai o te paanga o te pāmahana iti.
