42 Pipes with monitoring 3L® Leak Control Permeation resistant and permanently monitored pipe system that detects and reports damage and leaks. 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 a permeation resistant 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 ATVDVWK-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. Homogeneous inner pipe in PE100 RC with wall thickness according to EN standard. Permeation resistant and conductive aluminium layer to protect both media and the environment. High strength PEplus outer sheath. “Online” function monitoring. Reports possible damage to the pipe system.
