Black high-density polyethylene pipe, PE100RC type, with an external protective layer of additivated polypropylene (PP). PE100 RC (Resistant to Cracks) polyethylene offers superior resistance to crack propagation under stress compared to PE80 and PE100. The blue outer layer protects the pipe from mechanical stress, UV radiation, and prevents contamination. The dimensions of PE100RC pipes are standardized according to EN 12201-2, with the thickness of the external PP layer added to the standard pipe thickness. Reference Standard: PAS1075 (Public Available Specification) is a technical specification published by the Deutsches Institut für Normung, outlining characteristics, requirements, and testing methods for polyethylene pipes suitable for unconventional installation methods. Usage: WaterPro PE100RC pipes are used in pressurized drinking water supply networks, buried underground. Unconventional installation methods include: Horizontal Directional Drilling (HDD): Used for laying new pipelines or reconstructing old ones. This method is suitable for areas where open trenches are to be avoided (especially in urban areas where installation costs and traffic disruption are high). Burstlining: Breaking and replacing old networks. Relining: Rehabilitating old pipes. Approvals: DIN CERTCO Certificate of Conformity PAS1075 Type 3, verified in Lab. Hessel in Germany. Approval and technical agreement for use in construction. Sanitary approval for use with drinking water.
