PROPERTIES AND SALIENT FEATURES

Physical Properties

Malleable: The unique feature of KiTEC is its malleability. KiTEC is easily formed into curves, can be set by hand and require only bending springs when forming tight bends down to radius equivalent to 5 times the diameter of pipe. Unlike plastic plumbing pipes, KiTEC permanently holds whatever shape it is formed into and does not need additional brackets to retain the shape of bends or curves.

Non-Corrosive: KiTEC piping systems do not corrode. Will never pit or develop pin holes from aggressive water leading to premature failure.

Smooth Surface: No scale builds up to reduce flow. Soluble encrustants, such as calcium carbonate, do not readily precipitate onto the smooth walls of KiTEC pipes. In addition, there are no reduction in flow areas and flow coefficients as the pipes age.

Hygiene: KiTEC is hygienic, non-toxic, rust-free and eliminates growth of microorganisms. This avoids contamination of water. KiTEC pipes have passed all the tests of pipe for potable water in accordance with British Standard BS 6920 by the British Water Quality Centre.

Flame/Smoke Rating: KiTEC pipe has a Flame Spread of 5 and a Smoke Development of 5 as per ULC-S 102.2. The ratings meet most building code requirements allowing for the use of KiTEC in high-rise construction as well as in return air plenums and vertical shafts.

Permeation: KiTEC’s aluminum core acts as a permeation barrier against entry of contaminants and limits oxygen permeation to virtually zero. Permeation is the molecular transport of chemicals, from the soil surrounding the pipe, through the pipe wall and into the fluid being carried within. Permeation may have adverse effects on the piping system, the conveyed fluid or both. KiTEC is widely used for the transmission and distribution of potable water providing a second line of defence for the plumbing system.

UV Resistance and Opacity : KiTEC pipes do not have any effect of UV radiation when laid exposed. There is no light transmission through the wall of KiTEC pipe.

Thermal Properties

Thermal Expansion : KiTEC 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). This eliminates the need of installation “offsets” and the concern about abrading pipe due to constant movement as a result of temperature changes. Straight runs are always attainable with KiTEC pipe. Coefficient of Thermal Expansion for KiTEC Pipe is : 25 x 10-6/0K. Low expansion coefficient is due to tie layer which eliminates the differential expansion of plastic and metal.

Resistance to Freezing: In plumbing and water supply applications, KiTEC can withstand multiple cycles of freezing and thawing while under pressure without bursting up to –40°C. Temperature.

Thermal Insulation: KiTEC is having Thermal Conductivity of 0.43 Watt/ [m °K]. KiTEC composite pipes provide an increased resistance to the onset of condensation or pipe sweating in a plumbing application. In case of hot water piping, the insulation requirement is only 50% of the same required for conventional metal pipes.

Chemical Resistance

Resists at 20°C as well as 60°C.: Acids, Alcohol, Aldehyde, Ethylene Glycol, Bleach, Corrosion inhibitors, Detergents, Foodstuff, Petrol, Diesel, Fuel Oils, Veg/Mineral Oils.

Resists at ambient temperature. Performance yet to be ascertained at elevated temperatures. Beverages, Insecticides, Ketones, Oxidation Agents, Paints, Salts, Surfactants/Soaps.

Chlorine Resistance: KiTEC pipe has much better resistance to chlorine attack than other non-composite pipes because of the aluminum middle layer. The outer layer is not exposed to chlorine. Therefore, there is no method for chlorine attack on the outer layer. KiTEC pipes are an excellent choice for continuous re-circulation plumbing applications.
