Shell and tube heat exchanger

Tube heat exchanger

Introduce

High heat exchange speed, high temperature resistance (400°C) and high pressure resistance(2.5MPa); High efficiency and energy conservation: The heat transfer coefficient reaches

3000-4000W/m2.°C in the transfer from steam to water and 2000-3500 W/m2.°C in the transfer from water to water.

Structure design: --Tube type

§ Tube diameter: Using a small tube diameter makes the heat exchanger both economical and compact. However, it is more likely for the heat exchanger to foul up faster and the small size makes mechanical cleaning of the fouling difficult. To prevail over the fouling and cleaning problems, larger tube diameters can be used. Thus to determine the tube diameter, the available space, cost and the fouling nature of the fluids must be considered.

§ Tube thickness: The thickness of the wall of the tubes is usually determined to ensure:

§ There is enough room for corrosion

§ That flow-induced vibration has resistance

§ Axial strength

§ Availability of spare parts

§ Hoop strength (to withstand internal tube pressure)

§ Buckling strength (to withstand overpressure in the shell)

Heat transfer tube:

1) Pure seamless titanium tube . Thickness2 mm. The Grade is TA1.

2) The tube pressure loading capacity was designed base R410a high pressure work condition, The max. working pressure is 52 bar. and the extreme pressure was 360bar in our test.

3) 100,000 times alternating pressure (Low pressure 0 bar, high pressure 52bar) test shows it can be used more than 20 years. Never corrosion.

Specification:

2) The data list is our suggested data, We can produce any capacity heat exchangers according customer requirement and design.
