Since our establishment in 2017, Wuxi Yansheng Technology Co., Ltd. has been dedicated to manufacturing high-quality stainless steel products for industrial applications. Our High Performance Stainless Steel Heat Exchange Tube for Energy Efficiency is designed to maximize heat transfer while minimizing energy loss, making it an ideal choice for modern thermal management systems. With a factory spanning 1,000–3,000 square meters and a team of 101–200 experienced professionals, we have the capability to deliver tubes that meet rigorous international standards. Our annual export value of US$50 million–US$100 million reflects our commitment to quality and reliability in global markets.
These heat exchange tubes are manufactured from premium-grade stainless steel, offering excellent corrosion resistance, high thermal conductivity, and long service life. They are widely used in industries such as petrochemical, power generation, HVAC, food processing, and marine engineering. By optimizing the tube geometry and surface finish, we achieve higher heat transfer coefficients and lower pressure drops, contributing directly to improved energy efficiency in your systems.
Key Features & Technical Specifications
Material Options: Available in 304, 304L, 316, 316L, 321, 310S, and other austenitic stainless steels, selected based on corrosion resistance and temperature requirements.
Dimensional Precision: Outer diameters from 8 mm to 50 mm, wall thickness from 0.5 mm to 5 mm, with tight tolerances (e.g., OD ±0.05 mm, WT ±0.03 mm).
Length Customization: Standard lengths up to 18 meters; longer lengths available upon request for special projects.
Surface Treatment: Options include bright annealing, pickling, electropolishing, or plain finish, depending on the application needs.
Weld Technology: Both seamless and welded (TIG/high-frequency) tubes are available; welded tubes undergo strict non-destructive testing (NDT) to ensure weld integrity.
Enhanced Heat Transfer: Our tubes can be supplied with internal or external fins, corrugated profiles, or other enhanced surfaces to improve heat transfer rates by up to 30% compared to plain tubes.
Energy Efficiency: Optimized wall thickness and surface roughness reduce thermal resistance, enabling lower energy consumption in heat exchange processes.
Compliance: Manufactured in accordance with ASTM A249, ASTM A688, EN 10217, and other applicable standards. All tubes are tested for mechanical properties, dimensional accuracy, and leak tightness.
| Parameter | Typical Value | Remarks |
|---|---|---|
| Tensile Strength | ≥ 515 MPa (304) | Varies by grade |
| Yield Strength | ≥ 205 MPa (304) | Varies by grade |
| Thermal Conductivity | ~16.2 W/(m·K) (304 at 100°C) | Depends on alloy composition |
| Operating Temperature | -196°C to 800°C | For austenitic grades |
| Corrosion Resistance | Excellent in most environments | Select grade accordingly |
| Surface Roughness | Ra ≤ 0.8 μm (standard) | Can be improved for special applications |
Advantages for Your Business
Reduced Energy Costs: Improved heat transfer efficiency means lower energy consumption for the same thermal duty, directly reducing your operational expenses.
