Product Description
ASTM A179 Low-Carbon Steel Longitudinal Finned Tube For Refrigeration Systems
Product Description
ASTM A179 low-carbon steel longitudinal-finned tube is engineered for compact, high-efficiency heat exchange in refrigeration plants. The plain tube, made from killed low-carbon steel, offers ≥ 180 MPa yield and ≥ 35 % elongation, retaining impact toughness down to –45 °C. Fin pairs are roll-formed from the same low-carbon strip in a single pass, producing a cold-welded bond; fin ratios of 4–8 enlarge the air-side area, raising evaporating temperature by 2–3 °C and enabling chillers, cold-room air coolers and CO₂ transcritical racks to reach higher EER with lower refrigerant charge.
ASTM A179 Longitudinal Welding Fin Tube Strength
- Material Properties: ASTM A179 tubes are made from low-carbon steel with excellent weldability, offering optimal tensile and yield strength for welding applications.
- Welding Process: Utilizes controlled TIG (Tungsten Inert Gas) welding or high-frequency induction welding for strong, seamless longitudinal joints.
- Weld Quality: Rigorous non-destructive testing (NDT) including ultrasonic testing and radiography ensures defect-free welds without cracks or porosity.
- Heat Affected Zone (HAZ): Advanced welding techniques and optional post-weld heat treatment maintain structural integrity in the heat-affected areas.
- Fin Attachment: Durable extrusion or welding methods securely attach fins to withstand operational stresses without tube compromise.
- Standards Compliance: Meets all ASTM A179 specifications and welding standards for reliable performance in demanding applications.
- Testing & Certification: Verified mechanical properties including tensile strength, yield strength, and elongation, with optional third-party certification.
ASTM A179 Longitudinal Welding Fin Tube Applications
- Heat Exchangers: Essential in shell-and-tube heat exchangers for efficient liquid-to-liquid or gas-to-liquid heat transfer in chemical processing, oil/gas, and power generation industries.
- Condensers: Optimizes vapor-to-liquid conversion in power plants, refrigeration systems, and HVAC units through enhanced condensation efficiency.
- Boilers: Improves heat transfer in economizers and superheaters, recovering waste heat to boost boiler system efficiency.
- Air Coolers & Radiators: Dissipates heat effectively in automotive, HVAC, and industrial cooling applications through air-cooled heat exchangers.
- Refrigeration Systems: Critical component in evaporators, condensers, and chillers for commercial/industrial refrigeration and cryogenic applications.
- Petrochemical Processing: Enhances energy efficiency in heat recovery systems, preheaters, and coolers for refineries and chemical plants.
- Power Generation: Key element in HRSGs and condensers that improves thermal power plant efficiency through waste heat recovery.
- Marine Applications: Maintains optimal temperatures in marine engine systems and onboard equipment through specialized heat exchangers.
