Yes, copper tubing can be used in steam systems, including both steam and steam condensate piping.
While the use of copper in steam systems is possible, it's crucial to consider several factors to ensure its suitability and longevity:
- Pressure and Temperature Limits: Copper has specific pressure and temperature ratings. Exceeding these limits can lead to failure. Refer to relevant codes and standards (like ASME Boiler and Pressure Vessel Code) for guidance.
- Condensate Acidity: Steam condensate can become acidic, especially when dissolved gases like carbon dioxide are present. Acidic condensate can corrode copper piping. Consider condensate treatment to neutralize the acidity.
- Velocity Considerations: High steam velocities can cause erosion in copper piping, particularly at elbows and fittings. Properly size the piping system to maintain appropriate steam velocities.
- Joining Methods: Use appropriate joining methods, such as brazing with a suitable brazing alloy, to ensure leak-tight and durable connections.
In summary, while copper can be used in steam systems, proper design, installation, and maintenance are essential to ensure safe and reliable operation. Consider pressure, temperature, condensate acidity, and steam velocity to avoid potential issues.
