Gas Condenser and Heat Exchanger Fabrication

Industrial gas condensers and heat exchangers are essential to petrochemical, power generation, food and beverage, pharmaceutical, and other crucial applications where they act as thermal transfer units from high-temperature fluids. Even in everyday life, we regularly use these heat transfer units in our air conditioners and automobile radiators. The various functions heat transfer units accomplish include:

Heating water for CIP (Cleaning-In-Place)
Altering fluid chemistry through the application of heat and pressure
Maintaining the process temperature
Facilitating heat exchange without intermixing the two (ideal for sanitary application)
Promoting energy and cost-efficiency by reusing fluid in a repeated cycle.

To fulfill the functions described above, gas condensers and heat exchangers must adhere to a wide range of standards. Below, we’ll discuss how critical industries use these condensers and heat exchanger units and the importance of quality fabrication.

Gas Condensers and Heat Exchangers

Although they differ in definition, gas condensers and heat exchangers serve a similar function: they transfer heat. By definition, gas condensers condense high-temperature gas like steam and convert it to liquid. Heat exchangers transfer the temperature between two fluids, often to lower the gas temperature and convert it into liquid.

Heat Exchanger Fabrication Mechanism

The heat exchanger mechanism is applied in many ways across industries.

In the food and beverage industry, the heat exchanger facilitates temperature control to eliminate microbial growth and enable pasteurization or sterilization.
In industries with strict sanitation requirements, such as chemical processing, food, or biopharma, water can be used for cooling the process fluid. The heated water can then be used for CIP to ensure equipment and piping systems are safe and free of contamination.
In power generation plants, a heat exchanger or gas condenser extracts heat from the steam to condense it into the water so it can cycle back into the process.
In chemical plants, the heat exchanger can help chemical processing through heating or cooling (e.g., heating urea solution to convert into ammonia).

When processing chemicals and negotiating high temperatures and pressures, heat exchangers may induce corrosion or fail. Therefore, heat exchanger fabrication should adhere to established industry standards.

ASME BPVC Section VIII enumerates the design, fabrication, and inspection criteria when fabricating these heat exchangers. Only with orbital welding can manufacturers attain the precision and uniformity required to fabricate high-quality, standard-compliant heat exchangers.

Orbital Welding for Quality Heat Exchanger Fabrication

Using auto weld heads during gas condenser and heat exchanger fabrication can help operators ensure parameter control for precision and consistency. Additionally, a monitoring system will allow the welding operator to observe the welding process and exercise on-the-fly optimizations as needed.

The GTAW process is often considered ideal because of the clean and high-quality joints it fosters, which are essential when welding heat exchangers. By combining this process with the optimal weld materials and parameters, manufacturers can achieve safe and reliable heat exchanger fabrication.
