black high-density polyethylene pipe type PE100RC with outer protective layer of additive polypropylene PP. PE100 RC (Resistant to Cracks) polyethylene exhibits the property of resistance to crack propagation under load, compared to PE80 and PE100. The outer layer, blue in color, serves to protect the pipe against mechanical stress, UV radiation and to prevent contamination. The dimensions of the PE100RC pipe are standardized according to EN 12201-2, and the thickness of the outer PP layer is added to the standard pipe thickness. Reference standard: PAS1075 (Public Available Specification) is a technical specification published by Deutsches Institut für Normung, which includes the characteristics, requirements and test methods for polyethylene pipes that can be installed by unconventional methods. Application: WaterPro PE100RC pipes are used in pressurized drinking water supply networks, buried underground. Unconventional installation methods: Horizontal Directional Drilling HDD: used for laying new pipes or reconstructing old pipes. Suitable method 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, tests performed at Hessel Lab in Germany. Approval and technical agreement for use in construction. Sanitary approval for use with drinking water.
