Benefits
A versatile solution for industries that require a balance between the robustness of welded constructions and the flexibility of gasketed designs.
Key FeaturesLet’s explore the key features and characteristics associated with industrial semi-welded lines:
Semi-Welded Heat Exchangers
- In the context of heat exchangers, a semi-welded design combines the benefits of both gasketed and fully-welded heat exchangers.
- Some of the plates in the heat exchanger are welded together, providing a higher level of structural integrity and preventing cross-contamination between the two fluid streams.
- Other plates are gasketed, allowing for easier disassembly and maintenance.
Applications
- Industrial semi-welded lines are commonly used in applications where a high level of heat transfer efficiency is required, along with the flexibility of easy maintenance.
Corrosion Resistance
- The welded construction in some parts of the heat exchanger enhances corrosion resistance, making it suitable for applications involving corrosive fluids.
Flexibility
- The combination of welded and gasketed plates provides a balance between the stability of fully-welded designs and the flexibility of gasketed designs.
- This flexibility is particularly beneficial when dealing with processes that may undergo changes or require periodic maintenance.
Sealing Technology
- The gasketed plates use sealing technology to prevent leakage and ensure a secure separation between the two fluid streams.
- The welded portions provide additional structural support and enhance the overall integrity of the heat exchanger.
Temperature and Pressure
- Semi-welded lines are suitable for applications with moderate to high-temperature and pressure requirements.
- The welded construction allows for higher pressure ratings compared to fully gasketed designs.
Cleaning and Maintenance
- The modular design of semi-welded heat exchangers facilitates easier maintenance, as individual plates can be removed and replaced when necessary.
- Cleaning procedures can be implemented more effectively due to the accessibility of the plates.
Industry-Specific Applications
- These heat exchangers are used in various industries, including chemical processing, petrochemical, HVAC, food and beverage, and more.
