Double Pipe Heat Exchangers

A Simple Yet Highly Efficient Heat Transfer Solution

🌀 What is a Double Pipe Heat Exchanger?

A Double Pipe Heat Exchanger is a tube-in-tube heat exchanger where two fluids flow in opposite directions through the inner and outer pipes.
Its compact size and straightforward design deliver excellent heat transfer efficiency for small to medium flow rates.

🎯 Key Advantages of Double Pipe Heat Exchangers

1. Simple and Easy-to-Maintain Design

Its construction allows quick assembly, disassembly, and cleaning—ideal for reducing downtime in industrial operations.

2. Perfect for Low to Medium Flow Rates

More cost-effective than larger heat exchanger types while saving installation space.

3. Handles High Temperature and Pressure

Suitable for hot oil, steam, chemical processing, and other demanding applications.

4. Customizable Configurations

Available in Hairpin, U-Tube, or Straight Type, depending on process requirements and layout constraints.

5. Ideal for Specialized Applications

Highly suitable for Pilot Plants, Test Loops, R&D units, or small-scale production requiring precise temperature control.
