ASTM A192 boiler raj yog seamless carbon steel raj qauv siv los tsim cov cua kub saum npoo, headers, economizers, superheaters, reheaters thiab lwm yam khoom ntawm high-pressure boilers.
ASTM A192 npog yam tsawg kawg nkaus-phab ntsa-thickness, seamless carbon steel boiler, thiab superheater raj rau high-pressure kev pab cuam.Cov tubing qhov ntau thiab tsawg thiab thicknesses feem ntau muab rau cov specification no yog 1/2 in. to 7 in (12.7 mus rau 177.8 mm) sab nraud txoj kab uas hla thiab 0.085 rau 1.000 hauv (2.2 txog 25.4 mm), suav nrog, hauv qhov tsawg kawg nkaus phab ntsa thickness.
Nws yog feem ntau haum rau high-pressure boilers nrog ua hauj lwm siab tsis ntau tshaj 9.8MPa thiab ua hauj lwm kub ntawm 450 degree ~ 650 degree.
