Product Description

The ASTM A179 Carbon Steel U-Bend Tube is a seamless cold-drawn tube formed into a U-shape, specifically designed for use in heat exchangers, condensers, and boiler systems. This tube type enhances thermal efficiency by minimizing weld joints and maximizing heat transfer in compact layouts.

Chemical Composition (ASTM A179)

Element	Content (%)
C	≤ 0.06
Mn	0.27 – 0.63
P	≤ 0.035
S	≤ 0.035
Fe	Balance

Mechanical Properties

Property	Value
Tensile Strength	≥ 325 MPa
Yield Strength	≥ 180 MPa
Elongation	≥ 35%
Hardness	≤ 72 HRB
Max Operating Temp	Up to 400°C

Key Advantages

Compact Design
U-bending allows longer tube lengths to fit within limited spaces, reducing required shell diameter.
Fewer Welding Points
The continuous U-shape reduces the number of weld joints, lowering failure risks and improving system integrity.
Improved Thermal Efficiency
Seamless structure and uniform wall thickness ensure efficient heat transfer and fluid flow.
NDT Tested
Tubes are hydrotested and can undergo eddy current or ultrasonic testing to ensure reliability in pressure environments.

Applications

Commonly used in:

Heat Exchangers
Steam Condensers
Boiler Superheaters
Air Coolers
Oil and Gas Refineries
Power Plants (HRSG Units)
