Double-Walled Piping: Reliably Combining Safety and Environmental Protection
The safe and controlled conveyance of liquids is of central importance in many industrial sectors, especially when transporting water-hazardous, aggressive, or dangerous media. In such applications,
Design and Function of Modern Double-Walled Piping Systems
A key feature of double-walled piping is its design: an inner conveying pipe is surrounded by an outer containment pipe. This two-stage safety principle prevents dangerous media from entering the environment in the event of damage to the inner pipe. Should a leak nevertheless occur, the medium is collected in the annular space and detected early by an integrated leakage monitoring system.
Leakage Monitoring with Vacuum, Pressure, or Liquid
Depending on the requirements, different technical variants are available. In vacuum-monitored systems, the annular space between the inner and outer pipe is evacuated. Even the smallest leaks cause a pressure increase, which immediately triggers a warning signal. Alternatively,
Advantages of Integrated Leakage Monitoring
- Early detection of even the smallest leaks;
- targeted planning of maintenance measures;
- reduced risk of environmental contamination;
- minimization of costly consequential damages;
- higher operational safety for safety-critical industries.
Environmental Protection with Double-Walled Piping
These systems are primarily used where the highest demands are placed on environmental protection and operational safety. In the chemical and petrochemical industries, they enable the safe transport of hazardous media. In tank farms and at gas stations, they ensure that fuels do not enter the soil.
In addition to the safety aspect, these systems also offer a wide variety of materials: from steel to plastic, suitable materials can be selected depending on the medium and application area. This ensures not only a long service life but also the best possible chemical resistance.
Increased Occupational Safety: In the event of a leak in a single-walled pipeline carrying hazardous media such as acids, employee protection can be ensured by a double-walled pipeline.
Double-Walled Piping as a Sustainable Safety Solution
In summary, double-walled piping represents a technology that ideally combines necessary safety and environmental protection.
