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 not
arise when PVC is not exposed to sunlight, and will stop until exposure
terminates.
The cycle of discoloration
depends on time, and can be slowed down with the introduction of UV absorbers
in the PVC electrical conduit mix.
The degree to which sunlight
influences impact intensity depends on a number of factors, including: exposure
time, climatic conditions, pipe width, pipe wall thickness and form of PVC
compound used. It is difficult to predict how long it will take before the results
of exposure to sunlight are apparent owing to the combination of the variables.
In fact, smaller-diameter and thinner-wall pipes will have more benefit from
exposure to sunlight than bigger, thicker-walled pipes.
For permanent structures of plastic
pipe Karachi above ground, it is advised to shield the pipe from
exposure to sunlight. This can be achieved by covering the tubing or, more
generally, coating it with an opaque content. When painting the tubing, it is
advised to use a water-based paint designed for exterior use. Oil or
solvent-based paints may cause damage to the pipe and/or fail to stick well.
White or light-colored paints are best suited to minimize heat build-up.
Indoor or under-cover storage may
provide this. If the commodity is to be processed outside, it should prevent
heat trapping. Any plastic wrap used to secure the shipment during transit
should be removed before placement of the product in storage outside. Never
store pipe or fittings next to buildings that have direct exposure to sunlight,
particularly in summer months. Do not store heat-generating equipment near the
pipe or fittings.
Due to excessive heat build-up,
the pipe or fittings can deform. Pipe or fittings can be partially concealed
with a suitable material such as a white tarp or burlap. Black plastic should
never be used because of its characteristics which generate heat.
