PVC pipe is often used in underground and wet applications where electrical cables need to be protected. Because it is UV tested and rated, it can be used in places where it is exposed to UV rays.
Can PVC electrical conduit be used outdoors?
PVC pipe provides protection for underground electrical work. Of the many forms of pipe available, PVC pipe is considered the best for outdoor applications. … PVC tubing is also used for many electrical needs. This product is flexible and durable and resistant to corrosion.
How long does PVC last in the sun?
Sunlight makes PVC brittle. Exposed to the sun for 3-6 months and then buried, it will be affected. Changes in pressure or settling will cause the PVC to tear or fail in some way. Painting the line or keeping it out of direct sunlight will prevent this.
Which plastic pipe is UV resistant?
Based on these studies, Harvel Plastic, Inc. recommends that PVC and CPVC pipe products (i.e., PVC/CPVC products.
How to protect PVC pipes from UV rays?
For permanent above-ground PVC pipe installations, it is recommended that the pipe be protected from direct sunlight. This can be accomplished by wrapping the pipe in an opaque material or, more commonly, painting it. If the pipe is to be painted, a water-based paint formulated for exterior use is recommended.
What is the difference between white PVC and GRAY PVC?
Wall Thickness Schedule 40 PVC is typically white in color and Schedule 80 is typically dark gray (other colors are also available). However, their main difference lies in their design. Schedule 80 pipe has a thicker wall.
Does the outdoor cabling have to be laid in a cable duct?
Typically, local regulations require that outdoor wiring be protected by conduit if outdoor wiring is installed above ground. If the cabling is buried then most codes allow UF type cabling. However, some require the use of TW type cables and wires.
How long do PVC pipes last underground?
The Water Research Foundation has stated that 100 years is a conservative estimate for properly designed and installed PVC pipe. Excavation studies of PVC pipe materials around the world show no deterioration after decades of service.
Does PVC become brittle with age?
PVC pipe is a popular building material due to its low cost and durability. PVC pipe can be used for most drainage, water or ventilation applications. …PVC can become brittle and crack when placed in some situations for a long time.
Does UV light damage plastic?
All types of UV can cause a photochemical effect in the structure of the polymer, which can lead to deterioration of the material. High-energy UVC is most likely to affect plastics. Absorbed UV energy can excite photons in a plastic. Photon excitation can generate free radicals.
Does PVC pipe deteriorate in the sun?
Like many other materials, PVC plastics are also attacked by the effects of UV rays. …UV fading does not occur when PVC is not exposed to sunlight and stops when exposure ends. The fading process is time-dependent and can be slowed down by adding UV absorbers to the PVC compound.
