Anti UV Pipe
About 5% of sunlight is U.V. ray covering wavelengths of 280 to 400 nm. Solar radiation energy is usually measured with Langley unit (Ly):
The average solar radiation in kilo-Langley (KLy) for different countries is as following table:
Research and experiments show that if the pipes have been selected correctly, the U.V. rays do not have any effect on Faratec pipes.
In general, based on their installation method, pipes are classified into two types of buried and above-ground. In above-ground pipes, chemical U.V. absorber or mechanical U.V. reflective materials are used to prevent damages of U.V. rays. It is recommended to use U.V.-resistant additives if burial pipes are going to be exposed to the sun for more than one year.
