Stabi Composite Pipes PPR/AL/PPR

Stabi (PPR/Al/PPR) pipe is mechanically stabilized through the integrated aluminum layer. It is an extension range of PPR piping systems with better workability and lower thermal expansion. Pipe construction: homogeneous PPR inner pipe (according to EN ISO 15874 (2004) and DIN 8077/8078) with sealed aluminum layer and outer PPR cover layer.

The aluminum layer reduces the linear expansion coefficient to <0.035 mm/mK and protects inside PPR pipe preserving its properties and acting as an oxygen barrier: Stabi pipes can be welded with PPR fittings.

Main advantages in comparison with usual PPR pipes:

• Low thermal expansion α=0.03 mm/mK
• 100% oxygen barrier
• Increased supporting distance
• Better resistance to knocks
• High stability towards temperature and pressure

Application:

• Cold and hot water supply systems
• Potable water supply systems
• Heating systems
• Central air conditioning systems
• Water circulating and water supply
systems in swimming pools
