What are the Main Parts of Titanium Heat Exchangers?

A Titanium heat exchanger has several parts.

They all function towards completing an intended purpose – efficient heat transfer.

Some of the main parts of this device include:

· Titanium Tubes

The tubes are made using titanium material.

Tubes are small diameter pipes securely attached to the inside the shell.

It facilitates heat transfer creating the needed turbulence.

· Tube Sheets

Tube sheets isolate and support tubes in the titanium heat exchanger.

It is made from a flat piece of sheet with holes drilled to help the tubes stand in a pattern relative to one another.

Or, stand in the right location.

· Shells

A shell is the outer part of the device that encases the tube bundles.

On the surface of the shell are inlet and outlet pipes.

They bring in and out the fluids transferring heat in the device.

· Titanium Heat Transfer Plates

This component aids in heat transfer.

As fluids spread over the titanium places, it results in a large surface area for maximum heat transfer.

· Sealing Gasket

A gasket is a component that helps in sealing the device.

It joins the connections to the titanium heat exchangers.

· Pipe connection, flange and thread connection

These components act as the bridge between the device and the power source.

How does Titanium Heat Exchangers Work?

A Titanium heat exchanger helps transfer heat from one area to the other.

Put simply, inside a tube in the device, fluid flows via helical titanium encased in an insulated PVC barrel.

The second fluid flows over the titanium coil right inside the shell and rejects or absorbs heat depending on the intended purpose.

As the fluid flows in these tubes and pass one another, heat transfer takes place from the hot fluid to the cold fluid.

The fluid could take the form of a liquid/liquid, liquid/gas, or gas/gas.

The chosen fluid depends on the type of application for which it is intended.

In titanium heat exchangers without a helical coil, fluid flows through straight titanium tube bundles.

At the same time, water moves over and between these tubes.

Implying, there will be a larger surface area for cooling or heating.

The fluids involved (normally two) can flow at a right angle to one another.

That is, they can flow in opposite or same directions.

Below are some of the inspections and quality tests you can conduct on titanium heat exchangers.

· Pressure Testing

All Titanium heat exchanger samples must hold pressure proof of 800 PSI.

The devices are tested to burst pressure.

A burst at a specific temperature is shown by a leakage along the seam between the bar and header.

Often, this test is done in a swimming pool.

· Ultrasonic Testing

You can conduct this test to determine the integrity of the welded structure.

During the process, you will inspect various angles of the welded tubes.

Typically, there is a standard inspection of titanium heat exchangers as shown under the ASTM B338.

This test ensures that the device does not have any leaks.

· Eddy-Current Testing

This test is done to detect any cracks, pits, corrosion, and erosion.

You will conduct the test before putting this device into service to establish whether there were any damages during the installation and fabrication process.

It involves the use of electromagnet induction to detect and characterize any flaws on the surface of the device.

· Non-Destructive Testing

This test is done to evaluate the properties of the device; components, material, system or structure for welding defects or characteristic differences.

· Radiographic Testing

This test is done to determine the welding quality of the device.

An examination is done of the weld joints between the special connection fittings and device’s spiral manifolds.

An X-ray of the weld joints shows whether there are cracks or pores.

Once identified, the defects are re-welded to improve the quality of the joints/connections.

As such, the devices cannot leak when fluids are passed through them.

What are the Connection Types for Titanium Heat Exchangers?

This machine has two main types of connections:

What Causes Failure in Titanium Heat Exchangers?

Titanium heat exchangers often function at their optimum best.

However, they exhibit some failures which occur during operation.

Some of the causes of the failures in this device include:

· Clogged Air Filter

Clogged air filters cause the device to overheat resulting in stress cracks.

Stress cracks eventually cause leakages of the fluids in the tanks.

· Tube Corrosion

This problem occurs mainly in devices made with other materials other than titanium such as carbon steel.

Tube corrosion eventually leads to thermal permeation reduction resulting in the eventual deterioration of the tubes.

The tubes could be perforate and leak as fluid flow significantly reduces.

· Thermal Fatigue

The tubes of the device are often vulnerable to cracks and tears due to accumulated stresses associated with high-temperature differentials or constant thermal cycling.

If the device has a shell and tube side, it could suffer flexing.

This is because there is an extreme temperature difference between the two sides.

 Titanium jacket heat exchanger

Titanium jacket heat exchanger

High-temperature differentials also occur due to the physical thermal expansion as well as contraction of tubes along their length.

These issues compromise the integrity of the connection of the tube and the tube sheet.

As a result, there is significant leaks in shell and tube heat exchanger systems.

· Vibration and Resonance

This problem results in the exertion of powerful forces on heat exchanger tubes.

Thus, increasing intensity up to a point where tubes fail and rupture.

It also increases intensity until the tube loses their seal with the tube-sheet and leak.

Excessive tube velocities can also result in this problem.

It results in abrasion between the tube and the baffle edge.

The tube’s bond with the tube-sheet could fail or the tube could rupture.

When should you Replace Titanium Heat Exchangers?

You can replace Titanium Heat Exchangers if the device experiences irreparable damage/failure.

At this point, the device has ceased to function.

Similarly, you can replace this device if it has wear and tears that hamper its efficient operation.
