IFAN High Performance PEX EVOH Pipes

EVOH does not provide abrasion resistance
The EVOH layer is an internal oxygen barrier. It does not protect against abrasive water or sediment. The inner PEX layer is in contact with the water. PEX EVOH Pipe relies on the PEX layer for abrasion resistance.

Abrasion occurs on the inner surface
Sediment and particles flow through the pipe. They cause wear on the inner surface. The EVOH layer is not exposed to the water. PEX EVOH Pipe inner PEX layer handles abrasion.

PEX abrasion resistance
PEX is resistant to abrasion from suspended solids. It is a tough and durable plastic. It withstands most normal water conditions. PEX EVOH Pipe inner layer is designed for water flow.

Sediment and scaling
Hard water can cause scale buildup on the inner wall. Scale reduces flow and efficiency. PEX resists scale adhesion. PEX EVOH Pipe maintains flow with its smooth inner surface.

Water quality impact
Water with high sediment content causes faster wear. Constant particle flow erodes the inner layer. PEX EVOH Pipe performance may decrease over time. Example: high-sediment water reduces pipe life.

Example: municipal water supply
City water contains some sediment and particles. PEX EVOH Pipe handles this normally. The inner PEX layer resists abrasion. Example: decades of service without inner wear.

Example: well water system
Well water often contains sand and sediment. PEX EVOH Pipe can handle moderate sediment. A sediment filter is recommended. Example: protection against abrasive wear.

Effect on oxygen barrier
Abrasion does not affect the EVOH layer. The EVOH is protected by the inner PEX. The oxygen barrier remains intact. PEX EVOH Pipe barrier stays effective.

Resistance to scale
PEX has low surface tension, preventing scale adhesion. Minerals do not stick easily. PEX EVOH Pipe remains clean inside. Example: mineral buildup is minimal.

Extreme conditions
Highly abrasive water can damage PEX over time. Extreme sediment loads require special pipes. PEX EVOH Pipe is not suitable for slurry or mining applications. Example: use abrasion-resistant materials.

Proper filtration
Use filters to remove abrasive particles. This protects the pipe from wear. PEX EVOH Pipe benefits from good water quality.

Final abrasion summary
The EVOH barrier in PEX EVOH Pipe does not affect abrasion resistance. The inner PEX layer provides abrasion protection. PEX is resistant to normal sediment and wear. Scale adhesion is low. High sediment loads can cause wear. Use filters for water with high sediment. The oxygen barrier remains unaffected. PEX EVOH Pipe is suitable for typical water conditions. Example: maintain water quality for long pipe life.
