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.

ASTM A556 steel pipe can be delivered in U-bend form for use in feedwater heater applications.
The U-bend configuration allows for efficient heat transfer and is commonly used in tubular feedwater heaters.
ASTM A556 specification covers minimum wall thickness seamless cold drawn carbon steel pipe for these applications.
Tolerances according to specification or according to agreement. Standard tolerances are:
| Processing methods | OD | WT |
| Hot finished | +/- 1% | +/-12.5% |
| Cold finished | +/-0.75% | +/-10% |
