Yes, fully resistant
PPR-AL Stabi pipe is completely resistant to oxygen diffusion. The aluminum core acts as an absolute oxygen barrier. Oxygen cannot pass through the metal layer. Example: oxygen diffusion is effectively zero.
How the barrier works
Aluminum is a solid, continuous metal layer. Oxygen molecules cannot pass through solid metal. The aluminum is perforated but bonded with adhesives . PPR-AL Stabi pipe uses the metal to block oxygen completely.
Testing confirms the barrier
Manufacturers test oxygen permeability to DIN 4726. The standard requires less than 0.1 mg/m²·day. PPR-AL Stabi pipe meets this standard easily. Example: independent lab tests confirm the barrier.
Why oxygen is a problem
Oxygen in water causes corrosion in heating systems. Metal components rust and degrade. This reduces system lifespan significantly. PPR-AL Stabi pipe prevents oxygen from entering the system.
Protecting system components
Boilers, pumps, and valves are protected. Corrosion is eliminated or minimized. Maintenance intervals are extended. PPR-AL Stabi pipe increases the life of your heating system.
Comparison to standard PPR
Standard PPR pipes allow oxygen diffusion. Oxygen passes through the plastic wall. This causes corrosion in metal components. PPR-AL Stabi pipe is superior for heating systems.
Example: a closed heating system
A boiler system uses PPR-AL Stabi pipe throughout. Oxygen cannot enter the water. The boiler steel remains rust-free after 10 years. Example: a long-lasting, efficient heating system.
Example: an open system with PPR
An open heating system uses standard PPR pipe. Oxygen enters through the plastic walls. The boiler shows rust after 5 years. PPR-AL Stabi pipe would have prevented this damage.
German standards and compliance
German standard DIN 4726 specifies oxygen barriers. Pipes must have permeability under 0.1 mg/m²·day . PPR-AL Stabi pipe complies with this standard. Example: approved for use in Germany’s heating systems.
Benefits of oxygen barrier
No corrosion means no sludge or sediment buildup. System efficiency remains high. Pump life is extended significantly. PPR-AL Stabi pipe provides these benefits.
Oxygen barrier and water quality
The barrier also prevents algae growth. Light cannot pass through the aluminum layer. Water stays clean and fresh. PPR-AL Stabi pipe maintains water quality.
Final oxygen barrier summary
PPR-AL Stabi pipe is fully resistant to oxygen diffusion. The aluminum core blocks oxygen completely. It meets DIN 4726 standards for oxygen barriers. This protects boilers, pumps, and valves from corrosion. Standard PPR pipes do not provide this barrier. Use PPR-AL Stabi pipes for heating and closed-loop systems. Example: a reliable choice for long-lasting heating performance.
