ASTM A179 Carbon Steel Seamless Tube U Bend For Heat Exchanger
ASTM A179 Carbon Steel Seamless Tube U Bend Tube For Heat Exchanger Tube
Description:
ASTM A179 U-bend tubes are seamless cold-drawn carbon steel tubes specifically designed for heat exchanger systems, particularly where space-saving U-shaped bends are needed. The tubes offer excellent thermal conductivity and dimensional precision, making them ideal for shell-and-tube heat exchangers, condensers, and cooling coils.
The U-bending process is carried out with precision tooling and controlled heat treatment to ensure no wall thinning, no wrinkling, and optimal flow direction.
Chemical Composition (ASTM A179):
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.06 |
| Manganese (Mn) | 0.27 – 0.63 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Iron (Fe) | Balance |
Mechanical Properties:
| Property | Value |
|---|---|
| Tensile Strength | ≥ 325 MPa |
| Yield Strength | ≥ 180 MPa |
| Elongation | ≥ 35% |
| Hardness (Brinell) | ≤ 72 HB |
Advantages:
-
Precise U-bending with minimal deformation or thinning,Seamless tubes minimize the risk of leakage and offer better corrosion resistance compared to welded tubes.
-
