Black high-density polyethylene pipe, PE100RC type, with an outer protective layer of additive polypropylene (PP). PE100 RC polyethylene (Resistant to Cracks) offers resistance to crack propagation under load compared to PE80 and PE100. The blue outer layer protects the pipe against mechanical stress, UV radiation, and helps prevent contamination. The dimensions of PE100RC pipe are standardized in accordance with 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 Deutsches Institut für Normung, covering the 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. Trenchless installation methods: Horizontal Directional Drilling (HDD): used for laying new pipelines or reconstructing old pipelines. 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 carried out at the Hessel Lab in Germany. Approval and technical assessment for use in construction. Sanitary approval for use with drinking water.
