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 layer, blue in color, protects the pipe against mechanical stress, UV radiation and prevents contamination. PE100 RC (Resistant to Cracks) polyethylene has the property of resistance to crack propagation under load, compared to PE80 and PE100. The dimensions of the PE100RC pipe are standardized according to EN 12201-2, and the thickness of the outer layer of PP is added to the thickness of the standard pipe. Reference standard: PAS1075 (Public Available Specification) is a technical specification published by Deutsches Institut fr Normung, which includes the characteristics, requirements and test methods for polyethylene pipes that can be installed by unconventional methods. Use WaterPro PE100RC pipes are used in pressurized drinking water supply networks, buried in the ground. The maximum laying depth that allows the pipe to be detected is 6 meters from the lower generatrix, where the stainless steel wire is located. Unconventional installation methods: HDD horizontal directional drilling: used for laying new pipelines or reconstructing old pipelines. Method 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. Approvals DIN CERTCO Certificate of conformity PAS1075 Type 3, checks carried out in Lab. Hessel in Germany. Approval and technical agreement for use in construction. Sanitary approval for use with drinking water.
