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, serves to protect the pipe against mechanical stress, UV radiation, and to prevent contamination. Polyethylene PE100 RC (Resistant to Cracks) exhibits crack propagation resistance under load, compared to PE80 and PE100. PE100RC pipe dimensions 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 characteristics, requirements, and test methods for polyethylene pipes that can be installed using trenchless methods. Application: WaterPro PE100RC pipes are used in pressurized drinking water supply networks, buried underground. The maximum installation depth that allows pipe detection is 6 meters from the bottom generatrix, where the stainless steel wire is located. Trenchless installation methods: Horizontal Directional Drilling HDD: used for laying new pipes or reconstructing old pipelines. 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 agrément for use in construction. Sanitary approval for use with drinking water.
