How FibreFlex Pro Pipes are Jointed for Maximum Reliability and Efficiency

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.

Joint Components
Each FibreFlex Pro joint consists of three precision-engineered parts:

• Internal Steel Male Insert: Provides structural rigidity and ensures the secure seating of the joint inside the service pipe.
• Polymer Sleeve for High Temperatures: A unique design feature that enhances sealing performance, resists thermal expansion, and ensures long-term durability under demanding operating conditions.
• External Steel Ring: Holds the assembly firmly together under axial compression, ensuring a tight and stable joint.

Installation Process

• Position the Polymer Sleeve: The polymer sleeve is inserted between the fitting’s outer sleeve and the service pipe.
• Insert the Steel Male Fitting: The internal steel insert is pushed directly into the pipe end without the need for expansion.
• Apply Axial Compression: Using hydraulic clamps, the external steel ring is compressed, locking all components together.
• Final Insulation: The joint is sealed with high-density polyethylene (HDPE) shrinkable muffs or, for even greater performance, crosslinked polyethylene (PEX) shrinkable muffs, as commonly used in traditional steel preinsulated pipe systems.

Advantages of the FibreFlex Pro Jointing System
✅ Fast and Easy Installation: No pipe expansion required, reducing time and specialized tooling needs.
✅ High Temperature & Pressure Resistance: The polymer sleeve and steel components are designed for long-term performance under demanding conditions.
✅ Robust, Leak-Proof Connection: Axial compression fittings provide strong mechanical sealing that resists movement and pressure fluctuations.
✅ Compatibility with Proven Insulation Methods: Utilizes the same shrinkable muff technology as traditional steel preinsulated systems for consistent performance.

In short, FibreFlex Pro’s jointing technology delivers a secure, durable, and efficient connection method, perfectly suited for modern district heating, cooling, and industrial applications. By combining innovative materials with proven connection techniques, it ensures long service life and minimal maintenance.
