Pressure Vessel Steel Phaj Description
ASTM A516 specification yog tus qauv specification rau carbon steel siab nkoj daim hlau rau nruab nrab thiab tsawg kub daim ntawv thov thiab yog haum rau welded siab hlab ntsha xav tau kev txhim kho notch toughness. ASTM A516-70 thiab ASME SA516-70 steel phaj cov khoom yog tsim los ntawm carbon manganese steel thiab ua tau raws li lub siab lub nkoj zoo (PVQ) cov qauv teev tseg hauv ASTM A20 / ASME SA20.
ASTM A516 GR.70 thawv steel, lub npe lag luam PVQ steel phaj, yog nrov heev hauv ntau daim ntawv thov kev lag luam. Cov boards no kuj muaj nyob rau lwm qib xws li 60, 55 thiab 65. Tsis tas li ntawd, cov phaj no feem ntau yog siv los ua cov boilers qis thiab nruab nrab, cov hlab ntsha siab, thiab ntau yam khoom siv.
