A213 Seamless Carbon Steel Pipe Description
ASTM A213 or ASME SA213 seamless tube is applicable to seamless ferritic and austenitic pipes with the minimum thickness in boiler and superheater. It is typically used as heating surface pipe, boiler header and steam pipe in low and medium pressure boilers. This seamless steel pipe is widely applied in heat exchanger, condenser and heat transfer equipment. Selecting a steel pipe suitable for a specific application requires comprehensive consideration of multiple factors such as temperature, pressure, flow, material quality, corrosion protection and welding installation to ensure that the steel pipe can operate safely and reliably in the application scenario.
