3L^® Leak Control with “online” function check

Permeation resistant pipe system made of PE100 RC for the protection of e.g. drinking water (media) or the environment. Fitted with a high strength PEplus sheath. A permanently monitored pipe system that detects and reports possible damage in real time.

As the earth’s population continues to grow, the need to safely transport water and contaminants is increasing. Any leaks can have catastrophic consequences – if not detected in time.

3L^® Leak Control is a pipe made of PE100 RC equipped with a high strength PEplus sheath and an impermeable, conductive layer of aluminium that provides full control of possible leaks for optimal soil and water protection.

A monitoring device connected to the pipe issues an alarm even in the event of very minor pipe damage. The messages are then sent directly to the control centre or a mobile phone. The system can automatically shut down any connected pump systems, thereby preventing further impact caused by leakage at an early stage.

Permeation resistant and monitoring
In addition, the pipe’s intermediate layer, consisting of a conductive layer of aluminium, acts as an impermeable barrier that works in both directions. The pipe thus protects the transportation of drinking water when laid in contaminated ground, as well as sensitive environments where the pipe transports waste water or other contaminants through or near a water source, for example.

Extra protection against scratches and point loads
The pipe’s high strength sheath is made of PEplus, with a thickness, in the case of dim 250 mm/SDR17, corresponding to 25% of the pipe’s wall thickness.
In addition to protecting against scratches and pipe damage caused during pipelaying, the high strength sheath also helps to distribute the pressure from any point loads over a larger surface, thereby reducing impact on the main pipe. If necessary, the sheath material can be adapted to a specific application. 3L^® Leak Control meets the requirements of PAS 1075 Type 3 (pipes with a higher strength sheath).

Complete system with pipes, pipe fittings and wells
3L^® Leak Control includes a wide range of pipe dimensions, from 25 mm to 1200 mm in diameter. The complete system also includes customized pipe fittings and wells, as well as modern measuring technology for the rapid detection of possible pipeline damage.
In Germany, the 3L^® Leak Control pipe system meets the requirements for continuous leak monitoring according to ATV-DVWK-A 142 for use in connection with water source (drinking water) protection zone II with a high risk potential. However, similar standards do not yet exist in the Nordic market.

3L^® Leak Control with online monitoring of damage and leakage with automatic shut-off

3L^® is a complete system designed for the immediate detection of damage or leakage in pipelines that you wish to have complete control of. This allows you to take action quickly when necessary. Pipeline networks with 3L^® Leak Control are connected to a monitoring device that issues an alarm even in the event of very small damage to the pipe. An error message is then sent directly to the control centre or a mobile phone.
It is also possible to connect e.g. valves and pumps to a 3L^® monitoring device so these can be shut down if the pipeline suffers any damage.

Protection of the environment

3L^®is designed to protect the environment during the transportation of contaminated sewage. For example, when sewage water is to be routed through a water source or sensitive environment.

Protection of drinking water

3L^® is the best choice for industries that want full control of their pipeline network

Industries handling hazardous substances are concerned that they do not leak into the ground. As a result, more and more industries are choosing to install 3L® with online monitoring so that even minor leaks can be detected and corrected immediately. This minimizes the risk of future clean-up work and leakage of environmentally hazardous substances into the environment.

3L^® Leak Control is certified by KIWA, Class III (highest class) after long-term testing for impermeability and the effects of e.g. TCE (trichloroethylene). Pipe systems must have a service life of at least 50 years. According to calculations, 3L^® Leak Control can withstand penetration even after 100 years. Based on these tests and calculations, 3L^® has been certified by KIWA (BRL-K 170101).

3L^® Leak Control is resistant to aggressive media and can also withstand high pressures and temperatures for optimal ground and water protection.

Certified permeation resistance
KIWA is the institute that tests and issues certificates for impermeable barriers in polyethylene pipe systems.

The pipes are divided into two classes:
Class II For laying in ground where limited contaminants may occur that are higher than the limit values.
Class III For laying in ground where larger volumes of contaminants may be present.

3L Leak Control is tested and certified according to the highest Class III.
