Concept of Pex Pro Pipe
Pex Pro is an aluminium and polyethylene composite that combines the best features of both materials to form a pipe that is light, strong and does not support corrosion. By combining the two materials along with adhesive layers, Pex Propipe avoids the unaccepted thermal expansion and deformation of plastic pipe. At the same time it retains the flexibility, frost resistance and ease of use associated with plastic.
PROPERTIES AND SALIENT FEATURES
PHYSICAL PROPERTIES:
Non-corrosive: Pex Pro piping systems don’t corrode. Will never pit or develop pin holes from aggressive water leading to premature failure.
Smooth surface: That results in avoiding permanent scale build up avoiding reduction in flow. Soluble encrustants, such as calcium carbonate do not readily precipitate onto the smooth walls of Pex Pro pipes. In addition there is no reduction in flow coefficients as the pipe ages.
Hygiene: Pex Pro is hygienic, non-toxic, rust-free and eliminates growth of microorganisms. This avoids contamination of water. Pex Pro pipes have passed all the tests of pipe for potable water in accordance with British Standard BS 6920 by the British Water Quality Center.
Permeation: Pex Pro’s aluminum core acts as a permeation barrier against entry of contaminants and limits oxygen permeation to zero. Permeation is the molecular transport of gaseous chemicals, from the soil surrounding the pipe through the pipe wall and into the fluid being carried. Permeation may have adverse effects on the piping system, the conveyed fluid or both. Pex Pro is widely used for the transmission and distribution of potable water providing a second line of defense for the plumbing system.
UV Resistance and Opacity: Pex Pro pipes do not have any effect of UV radiation in outdoor installation. There is no light transmission through the pipe wall.
THERMAL PROPERTIES
Thermal Expansion: Pex Pro has a low coefficient of linear expansion similar to copper tubing and is far superior to alternate plastic pipe (expansion/contraction rate about 10% of plastic pipe).
Resistance to freezing: In continuous flowing plumbing and water supply applications, Pex Pro can withstand multiple cycles of freezing and thawing while under pressure without bursting up to -40 °C temperature.
