Online Leak Monitoring in Industry

Pipe systems with high hazard potential in industry are optimally monitored with the egeplast 3L safety pipe system – from any desired location.

The 3L safety pipe system from egeplast has been in use for many years in municipal, commercial and industrial applications. The advantages of the leak-monitored pipe from egeplast are not only becoming increasingly widespread, the monitoring system is also being continuously expanded. The latest development enables online control and maintenance of the monitored pipe system from any desired location.

The pipeline system, originally developed for the installation of sewage pressure pipes in water protection areas, has also become established in recent decades in applications such as landfill drainage, sewage treatment plant construction and in the industrial sector for contaminated process water and wastewater. Pipe systems with high hazard potential are optimally monitored when designed with the 3L safety pipe system!

The control of the pipeline system including fittings and manholes is achieved through permanent monitoring of the resistance to the ground by means of an aluminum barrier layer integrated into the pipe structure. In addition to the monitoring function, the aluminum barrier layer also ensures absolute permeation tightness of the pipe system. The simple structure and high flexibility of the material allow installation of the pipeline without restrictions in installation technology, e.g. in trenchless installation. Increased costs due to more soil excavation resulting from extended pipe outer diameters as with double pipes do not exist. Pipe rehabilitation projects using relining or burst lining can be easily implemented with the 3L safety pipe from egeplast. The flexible pipe lengths are very economical. By using coil bundles or pipe drums, for example, pipe lengths can be adapted to the section lengths on the construction site. This significantly reduces costs for pipe connections.

The connection of the pipes is created homogeneously by means of longitudinally force-locking welding through electrofusion welding or butt fusion welding. Continuous monitoring is ensured by simple re-wrapping of the connection point. Complex cascade welding or uncontrollable double welding is not required.

When using the 3L safety pipe system, no inspection manholes are necessary for leak monitoring. Monitoring takes place in a closed system. This saves civil engineering costs on the one hand and eliminates complex construction work on the other.

Depending on the project, the pipeline is monitored via a central or decentralized monitoring unit. Possible damage is detected and immediately reported via the grounding of the monitoring unit. The system detects an error early – before the pipe fails. This early warning system allows measures to be initiated before contamination occurs. The 3L safety pipe system automatically performs regular system tests, thereby ensuring 100% reliability of continuous monitoring. Since only a power supply for the monitoring unit must be provided, the 3L safety pipe system operates with very low maintenance costs. If a power supply for the monitoring unit is very difficult to implement, operation with a battery is also possible. High maintenance costs due to, for example, power consumption and maintenance of vacuum pumps do not exist.

Precise location of damage is difficult or only possible in sections depending on the pipe system. Complex, imprecise and therefore expensive excavations are necessary. With the 3L safety pipe system, the error can be located to within a decimeter.

If the insulation jacket and/or the medium pipe is damaged, repair of the 3L safety pipe system is possible in the shortest time. Special repair sets are available for the repair, enabling rapid restoration of the pipe and monitoring. Complicated repairs are not required.

Future developments of the 3L safety pipe system aim at combining different materials to meet requirements such as abrasion resistance, chemical resistance, protection against static charging or increased pressure resistance according to the needs of the customer project.

The development and application technology of egeplast support the customer from the initial consultation through system solution development and support on the construction site to project completion.
