Black high-density polyethylene pipe type PE100RC with outer protective layer of PP-modified polypropylene. A stainless steel wire is inserted under the protective layer to locate the position of the pipe. The outer blue layer protects the pipe against mechanical stress, UV radiation, and prevents contamination. PE100 RC polyethylene (Resistant to Cracks) has improved resistance to crack propagation under load compared to PE80 and PE100. The dimensions of PE100RC pipes are standardized according to EN 12201-2, and the thickness of the outer PP layer is added to the thickness of the standard pipe. Reference standard: PAS1075 (Public Available Specification) is a technical specification published by the Deutsches Institut für Normung, covering characteristics, requirements, and test methods for polyethylene pipes that can be installed using trenchless methods. Use: WaterPro PE100RC pipes are used in pressurized drinking water supply networks, buried in the ground. The maximum laying depth that allows pipe detection is 6 m from the lower generatrix, where the stainless-steel wire is located. Trenchless installation methods: Horizontal Directional Drilling (HDD): used for laying new pipelines or reconstructing old ones; suitable for areas where open trenches are to be avoided (especially in urban areas where installation and traffic disruption costs are high). Burstlining: breaking and replacing the old network. Relining: rehabilitation of old pipes. DIN CERTCO approvals: PAS1075 Type 3 certificate of conformity, tests performed at the Hessel Lab in Germany. Approval and technical assessment for use in construction. Sanitary approval for use with drinking water.
