Description

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.

Definition

The extrusion-based finning process generates an extensive, highly thermally conductive aluminum surface area, which drastically boosts the rate of heat transfer from the external gas medium to the internal fluid within the tube. The metallurgical bond formed during this process is of superior quality, which serves to minimize thermal contact resistance and maximize heat transfer efficiency.Base tubes for extruded finned tubes typically utilize materials such as carbon steel, copper, various alloys, and stainless steel. In contrast, the fin structures are commonly fabricated from copper, commercially pure aluminum grades 1060/1070, or aluminum alloys 6061/6063.

Key Applications

Shell-and-Tube Heat Exchangers for Condensation & Boiling: CondensersReboilers & Vaporizers
Petrochemical & Refining: Fired Heater Convection Sections
Heat Recovery Steam Generators
Applications Requiring Frequent or Aggressive Cleaning
