Multiple connection techniques supported: electrofusion, butt welding, socket welding, and mechanical compression.
One system. Complete accessories. Reliable connections.
Reliable connections are the foundation of every efficient district heating, cooling, or water network. Flexalen system accessories are purpose-designed to integrate seamlessly with all Flexalen pipe variants, ensuring homogeneous welded joints, secure mechanical connections, and long-term leak-tight performance. The range includes T-pieces, bends, elbows, Y-pieces, reducers, compression fittings with SDR11 threads, flange connections, and material transitions to steel or threaded systems.
Insulation kits for T-pieces, L-pieces, and socket joints ensure watertight, energy-efficient underground installations. Pipe clamps, rubber end caps, heat-shrink end caps, wall entry sealing sets, and warning tape complete the system. All components are tested and certified to EN 15632 and EN ISO 15876, reducing project risk and ensuring compliance with BRL KOMO 5609-2 requirements.
