The jointing process for FibreFlex Pro preinsulated reinforced flexible pipes is designed to combine speed, simplicity, and exceptional durability, ensuring a secure and leak-proof connection every time.

The system uses mechanical axial compression couplers, installed using hydraulic clamps specially engineered for this application. This method eliminates the need for pipe-end expansion, streamlining installation and reducing labor time on-site.

In modern infrastructure projects, pipe design efficiency directly impacts cost, performance, and sustainability. One design innovation that delivers measurable benefits is reduced wall thickness: a feature engineered into RK Infra’s Fibreflex flexible pipes.

Pipes may seem simple, but in reality, they are the silent workhorses of modern infrastructure. At RK Infra, we manufacture and supply high-quality pipes that power essential systems in St. Valentin, Linz, and Enns: from municipal water networks to industrial processing plants. Built with precision and designed for longevity, our pipes are trusted by engineers, contractors, and developers to keep projects running smoothly.

Pre-insulated FLEX pipes revolutionize pipeline installation with trenches up to 25% narrower than traditional steel pipes. This breakthrough technology offers significant advantages including reduced excavation volume (25-35% less), lower installation costs (up to 30% savings), and accelerated project timelines (15-25% faster). The lightweight, flexible, and corrosion-resistant properties of fibreflex pipes minimize environmental impact through reduced soil disturbance, lower carbon emissions, and decreased waste. Real-world implementation by RK Infra demonstrates impressive results: 32% less excavation, three-week faster completion, and 18% cost reduction. Fibreflex pipe technology represents a sustainable evolution in infrastructure development, delivering superior outcomes for both clients and the environment.

When it comes to building reliable infrastructure—whether for municipal water supply, industrial systems, or residential plumbing: the type of pipe you choose matters more than ever. With the evolution of piping technology, the decision is no longer limited to traditional materials like steel. Today’s projects demand solutions that balance strength, flexibility, installation efficiency, and long-term durability.
