ASME SA 78 tshav kub exchanger tube yog ib hom carbon steel raj hauv ASME (American Society of Mechanical Engineers) tus qauv, feem ntau yog siv los tsim cov cua kub saum npoo rau boilers thiab superheaters.
GNEE feem ntau muab SA178 raj rau qhov kev qhia tshwj xeeb hauv qhov ntau thiab tsawg ntawm 1⁄2 txog 5 ntiv tes [12.7 txog 127 mm] OD thiab cov phab ntsa tsawg kawg nkaus ntawm 0.035 txog 0. 360 nti [0.9 txog 9.1 mm] (nrog rau). Lwm qhov ntau thiab tsawg ntawm cov raj steel kuj tuaj yeem muab tau raws li qhov xav tau tiag tiag ntawm cov neeg siv khoom.
