ASTM A178 Welded Boiler Tube
SA178 yeeb nkab qhov ntau thiab tsawg thiab tuab feem ntau muab rau qhov kev qhia tshwj xeeb no yog 1⁄2 txog 5 hauv. [12.7 txog 127 mm] sab nraud txoj kab uas hla thiab qhov tsawg kawg nkaus phab ntsa thicknesses 0.035 txog 0.360 hauv. [0.9 txog 9.1 mm], suav nrog. Cov kav dej ntawm lwm qhov ntau thiab tsawg tuaj yeem muab tau yog tias cov kav dej no ua tau raws li txhua qhov kev xav tau ntawm qhov kev qhia no.
