ASTM A179 / ASME SA179 Low Carbon Steel U Bending Tube For Heat Exchanger
ASTM A179 / ASME SA179 is a specification for seamless cold-drawn low-carbon steel tubes specifically designed for heat exchangers, condensers, and similar heat transfer applications. These tubes are known for their high precision, excellent surface finish, and superior thermal conductivity, making them ideal for use in applications requiring efficient heat transfer.
When these tubes are bent into a U-shape, they are commonly referred to as U-bending tubes, which are widely used in heat exchanger systems like shell-and-tube heat exchangers to optimize the flow of fluids and heat transfer efficiency.
Key Features of ASTM A179 / ASME SA179 U-Bending Tubes
Material Composition:
Made from low-carbon steel as per ASTM A179 / ASME SA179 specifications.
Low carbon content improves ductility and weldability while maintaining good strength and durability.
Manufacturing Process:
Seamless cold-drawn construction ensures high dimensional accuracy and smooth surfaces.
U-bending is done with precision to avoid deformation, wall thinning, or cracking.
Applications:
Widely used in heat exchangers, condensers, boilers, and superheaters.
Suitable for industries such as power generation, chemical processing, petroleum refining, and HVAC systems.
Advantages:
High thermal conductivity for efficient heat transfer.
Excellent corrosion resistance, especially when coated or treated for specific environments.
Precise bending ensures minimal pressure drop and optimized flow dynamics.
Specifications:
Outer Diameter (OD): Typically ranges from 6mm to 88.9mm.
Wall Thickness: Ranges from 1mm to 12mm, depending on application requirements.
Bend Radius: Customizable as per customer requirements, typically 1.5D, 2D, 3D, etc.
Length: Straight lengths or custom U-bend lengths based on design specifications.
Standards and Testing
Standards: Conforms to ASTM A179 / ASME SA179 specifications.
Testing:
Hydrostatic testing ensures no leaks or defects.
Non-destructive testing (NDT) like eddy current or ultrasonic testing for surface and internal integrity.
Dimensional checks to ensure precision in bending and compliance with design tolerances.
Common Applications
Heat Exchangers: U-bending tubes form the core of shell-and-tube heat exchangers, allowing fluid to flow through the tube bundle.
Condensers: Used in power plants and industrial systems to condense steam or gases into liquid phases.
Boilers: Ideal for high-pressure and high-temperature environments where heat transfer is critical.
