Is there a standard for steel used in high-pressure shell-and-tube heat exchangers? Operating pressure: 63 kg, medium: hydrogen & circulating water
63 kilograms corresponds to medium pressure, and the standards for heat exchange tubes used in medium pressure are: GB8163, GB3087, and GB9948. ≥100 kilograms corresponds to high pressure; the relevant standards are GB6479, GB5310, and GB14976.
