Product Introduction
Baishunxing Pipe Industry Pipe Industry PPR-EVOH Oxygen Barrier Pipe is a high-performance multi-layer composite pipe designed specifically for closed-loop heating and HVAC systems. By integrating an EVOH (Ethylene Vinyl Alcohol) layer, it effectively blocks oxygen from entering the water stream, preventing the oxidation and corrosion of expensive metal components like boilers, pumps, and valves.
Key Features
Superior Oxygen Barrier (EVOH Layer)
Complies with DIN 4726 standards, reducing oxygen permeability to less than 0.32 mg/(m²·d).
5-Layer Composite Technology
Consists of PPR (inner), Adhesive, EVOH, Adhesive, and PPR (outer) for maximum structural integrity.
System Protection
Prevents the growth of aerobic bacteria and algae, maintaining a clean and efficient heating system.
High Temperature & Pressure Rating
Typically rated at PN20/PN25, ensuring safety in long-term high-temperature heating cycles.
Technical Advantages
Extended Equipment Life
Drastically reduces maintenance costs by eliminating the root cause of metal corrosion in boilers and radiators.
High Flow Efficiency
Retains the smooth inner bore of standard PPR, preventing scale buildup even in complex heating loops.
Easy Installation (Heat Fusion)
Compatible with standard PPR socket fusion fittings, requiring no special peeling tools (for 5-layer types).
Application Scenarios
Underfloor Heating Systems : Ideal for radiant floor heating where oxygen diffusion can damage manifold systems.
Radiator Connections: Main supply lines for high-temperature radiator heating networks.
Central Air Conditioning : Chilled and hot water circulation in residential and commercial buildings.
Boiler Room Piping : Crucial for connecting heat sources to the distribution network.
