Black high-density polyethylene pipe type PE100RC with outer protective layer of PP additive. PE100 RC polyethylene (Resistant to Cracks) has the property of resistance to crack propagation under load, compared to PE80 and PE100. The outer layer, blue, has the role of protecting the pipe against mechanical stress, UV radiation and preventing contamination. 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 drinking water supply networks under pressure, buried in the ground. Unconventional installation methods: Horizontal directional drilling HDD: used for laying new pipelines 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, checks carried out in Lab. Hessel from Germany. Approval and technical agreement for use in construction. Sanitary approval for use with drinking water.
