introduction

ASTM A556 steel pipe is a seamless carbon steel boiler and superheater tube used for high temperature service, especially in boiler and superheater applications. ASTM A556 carbon steel pipes are available in different grades such as Grade A2, Grade B2, and Grade C2. ASTM A556 seamless steel pipe is mainly used in high temperature heater systems.

ASTM A556 boiler steel tubes are primarily used in feed water heating systems in boilers and superheaters. Due to their excellent high temperature resistance and corrosion resistance, these steel pipes can operate stably for a long time in harsh working environments, ensuring the safe and reliable operation of feed water heaters.
