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.

Key Features

ASTM A213 304L
Tube

· Tensile Strength: ≥485 MPa
· Yield Strength: ≥170 MPa
· Elongation(2 inches): ≥ 35% in 50 mm
· Hardness: ≤ 192 HBW/ 90 HRB

· Low-carbon austenitic stainless steel (C≤0.03%) with enhanced resistance to intergranular corrosion, especially suitable for welding and high-temperature applications.

· High chromium-nickel content (Cr 18-20%, Ni 8- 12%) provides excellent oxidation and acid/alkali resistance for harsh environments like chemical and marine applications.

· Maintains good strength at elevated temperatures, ideal for boilers, heat exchangers, and petrochemical equipment under high pressure/temperature.

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
