ASTM A213 TP304L Stainless Steel Corrugated Tube Enhanced Heat Transfer in Heat Exchanger

ASTM A213 TP304L Stainless Steel Corrugated Tube is a specialized heat exchanger component designed to optimize thermal performance. Its corrugated surface structure increases turbulence and heat transfer efficiency while maintaining structural integrity. Manufactured from ASTM A213-compliant TP304L austenitic stainless steel, it provides excellent advantages of strong corrosion resistance, longer service life, no pitting corrosion and low price. The tube is particularly suitable for shell-and-tube heat exchangers, condensers, and other heat transfer systems requiring enhanced performance.

1.Chemical & Mechanical Properties

Mechanical Properties

2. Key Features

(1) Optimized Heat Transfer Performance

• Corrugated surface design increases turbulence and improves heat exchange efficiency by 20-30% compared to smooth tubes.
• Special groove structure enlarges heat transfer area while maintaining low flow resistance.

(2) Superior Material Properties

• Made of ASTM A213 TP304L low-carbon stainless steel with excellent corrosion resistance
• Maintains good mechanical strength at high temperatures (up to 800°C)

(3) Long Service Life

• Excellent resistance to scaling and fouling
• Maintains stable performance over long-term operation

(4) Energy Saving & Compact Design

• Reduces equipment size by 15-25% while maintaining same heat transfer capacity
• Lowers energy consumption through improved heat transfer efficiency

(5) High cost performance

• The linear expansion coefficients of dirt and metal corrugated tubes are very different, so automatic descaling can be achieved, and the operation and maintenance costs are low.
• Ultra-thin wall stainless steel products have low weight, save materials, reduce floor area, and have obvious economic benefits.

3. Key Applications

(1) Petrochemical Industry

• Heat exchangers for crude oil refining and petrochemical processing
• Condensers and reboilers in ethylene/propylene production

(2) Power Generation

• Feedwater heaters and condensers in thermal power plants
• Waste heat recovery systems in nuclear power stations

(3) Marine & Offshore

• Seawater desalination systems
• Marine engine cooling systems

(4) HVAC & Refrigeration

• Central air conditioning chillers
• Refrigeration system evaporators
