Heat Conducting Pipe in Seawater Desalination Equipment

Titanium Heat Conducting Pipes are widely used in seawater desalination systems due to their exceptional resistance to corrosion, long service life, and reliable heat transfer performance. Compared with traditional copper alloy or stainless steel tubes, titanium pipes provide superior durability in high-chloride environments, making them the preferred choice for modern desalination plants.

With increasing demand for efficient and maintenance-free desalination systems, titanium tubes have largely replaced conventional copper alloy tubes, offering improved reliability and reduced lifecycle costs.

Key Features

• Outstanding Corrosion Resistance
  Highly resistant to chloride ions, seawater, and marine environments

• Long Service Life
  Minimal degradation, reducing replacement frequency

• Lightweight & High Strength
  Lower density reduces structural load and installation costs

• Anti-Fouling Performance
  Smooth surface minimizes scaling and biological attachment

• Low Maintenance Requirements
  Maintenance-free operation in most desalination systems

• Flexible Design Options
  Available in thin-wall welded or seamless configurations

Applications

Titanium heat conducting pipes are essential components in:

Seawater desalination plants (MSF, MED, RO preheating systems)

Marine heat exchangers

Power plant cooling systems

Offshore platforms

Solar desalination systems

Technical Characteristics

1. Wall Thickness Design

The wall thickness of titanium heat conducting pipes is optimized based on:

Operating conditions

Tube sheet material compatibility

Expansion and welding requirements

Typical comparison:

Copper alloy tubes: 0.9 – 1.2 mm

Titanium tubes: can be reduced to ~0.3 mm (welded thin-wall design)

This allows significant material and weight savings while maintaining performance.

2. Thermal Conductivity

Although titanium has lower thermal conductivity, this is effectively compensated by:

Thinner wall thickness

Reduced fouling and scaling

Long-term stable heat transfer efficiency

3. Economic Advantage

Titanium tube price: 2–6× higher per kg than copper alloys

However:

• Titanium density is lower

• Wall thickness can be reduced by up to 50%

• Total system weight reduced significantly

Result:

• Comparable overall cost to aluminum brass

• More cost-effective than Cu-Ni alloys over lifecycle

• Lower maintenance and replacement costs
