Product Description
A serrated finned tube is a high-efficiency heat exchanger component designed to maximize thermal transfer by increasing surface area and promoting fluid turbulence. The ASTM A213 TP316 Serrated Spiral HFW Finned Tube with Stainless Steel Fins offers exceptional performance in demanding industrial environments.
Key Features
- ASTM A213 TP316: Seamless austenitic steel tube with excellent corrosion resistance and high-temperature strength
- Serrated Spiral Fins: Helically wound fins with notched edges to enhance turbulence and heat transfer
- HFW Construction: High-frequency welded fins ensure strong, durable bonds with minimal distortion
- Stainless Steel Fins: Matching SS316 material provides uniform corrosion resistance
Material Properties
Chemical Composition (Weight %)
| Element | SA213 TP316 Requirements | Typical Values |
|---|---|---|
| Carbon (C) | ≤ 0.08% | 0.04-0.08% |
| Manganese (Mn) | ≤ 2.00% | 1.00-2.00% |
| Phosphorus (P) | ≤ 0.045% | ≤ 0.030% |
| Sulfur (S) | ≤ 0.030% | ≤ 0.020% |
| Silicon (Si) | ≤ 1.00% | 0.30-0.70% |
| Chromium (Cr) | 16.0-18.0% | 16.5-17.5% |
| Nickel (Ni) | 10.0-14.0% | 10.5-13.5% |
| Molybdenum (Mo) | 2.00-3.00% | 2.10-2.60% |
TP316L (low carbon variant) has C ≤ 0.035% for improved weldability. Iron (Fe) makes up the remainder.
Mechanical Properties
| Property | SA213 TP316 Requirements | Typical Values |
|---|---|---|
| Tensile Strength (MPa) | ≥ 485 | 515-620 |
| Yield Strength (MPa) | ≥ 170 | 205-310 |
