Yes, UV protection is essential
PEX EVOH Pipe requires protection from UV light during storage. The outer PEX layer degrades from sunlight. The EVOH layer does not provide surface protection. Example: UV damage makes the pipe brittle and weak.
How UV damages PEX
UV radiation breaks down the PEX polymer chains. The surface becomes brittle and cracks. This weakens the pipe structurally. PEX EVOH Pipe loses strength when exposed to UV.
The EVOH layer does not help
EVOH is inside the pipe structure. It does not protect the outer PEX layer. UV only affects the outer surface. PEX EVOH Pipe has no UV protection from its layers.
Maximum UV exposure time
Most manufacturers allow 12 months of outdoor storage. Beyond that, the pipe is compromised. Direct installation in sunlight is not permitted. PEX EVOH Pipe needs protection immediately.
Methods for UV protection
Store pipes indoors or under cover. Use opaque covers for outdoor storage. Keep them away from windows. PEX EVOH Pipe should be shielded from sunlight.
Example: proper storage in warehouse
A distributor stores PEX EVOH Pipe in a warehouse. The pipes are away from windows. The storage area is covered and shaded. Example: safe, long-term storage.
Example: improper outdoor storage
A contractor stores pipes outside in the sun. The pipes are exposed to UV. PEX EVOH Pipe degrades from exposure. Example: the pipes become brittle and unusable.
Storage guidelines
Store pipes in a dry, shaded area. Keep temperatures between 5°C and 40°C. Use the pipe within 12 months. PEX EVOH Pipe needs proper storage conditions.
Handling during installation
Protect pipes from UV during installation. Cover them when not in use. Install them promptly after removing covers. PEX EVOH Pipe requires care during installation.
Signs of UV damage
Discoloration of the pipe surface. Cracking or brittleness. Loss of strength and flexibility. PEX EVOH Pipe UV damage is visible.
Long-term outdoor performance
Without protection, outdoor life is short. With protection, it lasts decades. Protection is mandatory for outdoor use. PEX EVOH Pipe can serve outdoors when protected.
Final storage summary
PEX EVOH Pipe requires UV protection during storage. Store indoors or under opaque covers. Maximum outdoor storage is 12 months. UV damages the outer PEX layer. The EVOH layer does not help. Proper storage ensures long-term performance. PEX EVOH Pipe is reliable when properly stored. Example: protect your investment with proper storage.
