How to Protect Your PVC Electric Conduit?
PVC pipe that has been subjected to ultraviolet light for long periods of time loses any strength but not enough to cause a significant decrease in the capacity of the tube to withstand water pressure. Ultraviolet rays often cause changes in color to the outside of the tubing. You will avoid the problem by coating with an ultraviolet-resistant paint some PVC pipes in your house that are specifically exposed to the sun. PVC electrical conduit exposure to the UV component of sunlight results in PVC molecules being permanently converted into a complex structure typified by polyene formations in the first.001 "to.002" of the exposed surface. The effect is a discolouration, also referred to as "Sun discolouration," "UV oxidation," or just "sunburn." The pipe's coating can shift first by losing shine, leading to chalking and discoloration. (Typically, discoloration will advance yellow to brown to black) UV discoloration will
