ASTM A213 TP304 Extruded Finned Tubes For Fired Heater Convection Sections
The convection section functions as a vital heat recovery assembly within direct-fired heaters (also referred to as furnaces) that are utilized in refineries, petrochemical facilities, and chemical processing plants. The engineering and configuration of this section exert a direct influence on the heater’s overall thermal performance efficiency and the economic viability of its day-to-day operation.
For the convection sections of fired heaters, extruded (integral) finned tubes transcend the status of a mere optional component to become a mandatory solution. It is the sole technology that can ensure long-duration, reliable heat recovery with optimal efficiency, despite being exposed to the combined stresses of high heat, corrosive media, fouling accumulation, and cyclic thermal fluctuations.
ASTM A213 is a Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.
