| High Light | ASTM A269 TP316L corrugated tubes ，heat exchanger corrugated tubes ，enhanced heat transfer TP316L tubes | ||
Our ASTM A269 TP316L corrugated tubes are engineered specifically for high-efficiency heat exchanger applications where enhanced heat transfer, superior corrosion resistance, and long service life are critical. Manufactured from premium-grade 316L austenitic stainless steel, these corrugated tubes provide a larger effective heat transfer surface area than conventional smooth tubes while improving fluid turbulence and reducing fouling tendencies.
Designed for demanding industries such as petrochemical processing, power generation, marine engineering, food processing, pharmaceutical manufacturing, and HVAC systems, ASTM A269 TP316L corrugated tubes offer excellent resistance to chloride environments, organic acids, and a wide range of corrosive media.
The following dimensions are commonly available for heat exchanger applications:
| Outside Diameter (OD) | Wall Thickness | Length |
|---|---|---|
| 6.35 mm (1/4") | 0.5 - 1.0 mm | Up to 30 m coil |
| 9.52 mm (3/8") | 0.5 - 1.2 mm | Up to 30 m coil |
| 12.70 mm (1/2") | 0.6 - 1.5 mm | Up to 30 m coil |
| 15.88 mm (5/8") | 0.7 - 1.5 mm | Up to 30 m coil |
| 19.05 mm (3/4") | 0.8 - 2.0 mm | Up to 24 m coil |
| 25.40 mm (1") | 1.0 - 2.5 mm | Custom lengths |
Custom dimensions can be manufactured according to project specifications and heat exchanger design requirements.
| Element | Composition (%) |
| Carbon (C) | ≤ 0.035 |
| Manganese (Mn) | ≤ 2.00 |
| Silicon (Si) | ≤ 1.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 16.00 - 18.00 |
| Nickel (Ni) | 10.00 - 14.00 |
| Molybdenum (Mo) | 2.00 - 3.00 |
| Nitrogen (N) | ≤ 0.10 |
The addition of molybdenum significantly improves resistance to pitting and crevice corrosion, particularly in chloride-containing environments.
| Property | ASTM A269 TP316L |
| Tensile Strength | Minimum 485 MPa (70 ksi) |
| Yield Strength (0.2% Offset) | Minimum 170 MPa (25 ksi) |
| Elongation | Minimum 35% |
| Hardness | Maximum 90 HRB |
| Density | 8.0 g/cm³ |
| Melting Range | 1370 - 1400°C |
These mechanical characteristics ensure excellent pressure-bearing capability and durability in heat exchanger operations.
Strict quality control procedures are implemented throughout the manufacturing process to ensure consistent performance and compliance with international standards.
To guarantee product quality and reliability, ASTM A269 TP316L corrugated tubes undergo comprehensive testing procedures, including:
Inspection reports and third-party certifications can be provided upon request.
Our corrugated stainless steel tubes are manufactured using advanced production technology and rigorous quality assurance procedures. By combining premium TP316L stainless steel with optimized corrugation geometry, we deliver products that maximize heat transfer efficiency, reduce maintenance costs, and provide reliable performance in the most demanding industrial environments.
Whether you require standard sizes or fully customized solutions, our engineering team can provide technical support and tailored manufacturing services to meet your specific heat exchanger requirements.
