Cross - Linked Polyethylene (PE-X)which stands for cross-linked(X) Polyethylene (PE), results from chemically adjoining polyethylene molecules in order to improve their properties, especially at high temperatures. This, results in a structure that stays rigid when high temperature is applied, thus raising the thermal stability of the material under load. Cross-linking makes PEX a “thermoset” polymer, which gives it long-term stability, which greatly increases the environmental stress crack resistance and the resistance to slow crack growth due to deterioration of the material under continuous temperature use.

Mechanical Characteristics of PEX.The technical suitability of PEX for water delivery systems has been proven for decades. The conceptPEX® pipe system is designed for continuous temperatures of 0 °C to 70 °C, short-term peak temperatures of up to 100 °C and a service life of min. 50 years.

The cross-linking raises the thermal stability of the material under load. Thus, the resistance to environmental stress cracking, creep, and slow crack growth are greatly improved over polyethylene.

PEX pipe is approved for potable hot and cold water plumbing systems and hot water (hydronic) heating systems in all model plumbing

Moreover, conceptPEX® Pipe shows unique temperature resistance at elevated temperatures and for long service periods and offers a reliable piping system even in the wide application ranges.

Resistance to PressureAt room temperature, cross linking greatly improves the resistance of conceptPEX® pipes to pressure, reducing tendency to creep. At higher temperatures, this is achieved by reducing intermolecular space, and therefore density, required for DIN 16892 standards. To meet the pressure regulations for flexible under-floor heating pipes, a minimum density of 0.945 to 0.950 is required.The following diagram shows the service life expectancy which depends on the installed system pressure and pressure changes. Under nominal circumstances, however, the service life expectancy of the pipes is more than 50 years.

fore influence the quality. PEX pipes are non-toxic material which make it suitable for drinking water application and included in all of the major model plumbing codes.

UV ResistanceconceptPEX® piping system is designed for indoor and buried applications only and is not recommended for outdoor above ground use. Short indirect exposure to sunlight not to exceed 30 – 45 days are however, permissible when storing conceptPEX®. However it is necessary that the pipes, if stored outside, be shielded from direct sunlight.

Like most plastics, the long-term performance of PEX will be affected by UV radiation from sunlight. Although most PEX pipes have some UV resistance, PEX pipes should not be stored outdoors where they are exposed to the sun. Precautions must be taken once the pipe is removed from the original container.

In most applications, conceptPEX® piping system is not normally installed where subjected to UV-radiation. If exposure to UV rays is unavoidable, then the PEX pipes should be buried in the soil or protective UV rays insulation shielding should be installed. Indirect (diffused) and reflected sunlight also has UV energy. If PEX is exposed to sunlight continuously after installation, such as an unfinished basement, the pipe should be covered with a UV-blocking sleeve (black preferred) or approved pipe insulation.

conceptPEX® pipes and fittings are, however, UV protected with the external packaging upon delivery to allow time for storage, transport and installation for a period of up to 6 months in exposed areas. The protective package should not be removed until installation is commenced.

DurabilityBased on extensive testing and material performance over the span of more than 30 years, PEX piping has proven to be a durable material that does not suffer from some of the historical problems associated with metallic piping, such as reduced interior dimension, corrosion, electrolysis, filming, mineral build-up, and water velocity wear. PEX piping will typically expand if the system is allowed to freeze, and return to its original size when the water thaws.

Corrosion Resistant Brass FittingsBrass components have been widely used in the water industry. When supply of potable water is required, however, and in certain combinations of chloride concentrations in an acidic medium, corrosion of the alloy will occur and is due to the loss of a basic alloying element. To counter this problem, alloys such as dezincification resistant brass alloys (DZR) and other brass compositions approved by German Water authority DVGW have proven to be effective in resisting this corrosion. These alloys are unique through combining a range of alloying elements including high copper content and small traces of other alloys, and subsequently post processing their microstructure of the alloy to chemically resist the attack of the medium and prevent the brass from corrosion. All conceptPEX® brass fittings conform to DVGW requirments.

Hygienic PropertiesFor the healthy and safe delivery of potable water, the network system used must be free from any interactions or reactions or influence on the delivered fluid. This includes all materials and processes used that will be in contact with the water, and there

Fire Resistance:conceptPEX® pipes do not omit toxic gases in the case of fire, thus minimizing risk of developing dioxin or other lethal or harmful gases such as hydrogen chloride.

Fire protection guidelines are set in accordance to national regulations. conceptPEX® materials fulfill requirements of fire class DIN 4102-B2 (normally inflammable materials).

Chemical Resistance:Due to the nature of polyethylene, conceptPEX® pipes are highly chemical resistant at a wide range of temperatures and pressures. The basic cross linked structure physically is resistant to the attack of aggressive chemicals. The material is thus rendered more resistant to permeation and softening by these chemicals.

Installation:The installation of PEX pipe is generally easier than rigid pipe. The pipe is lightweight compared to steel or copper pipes, making it easy to transport and safe to handle before and during installation, and as conceptPEX® pipes are produced in various length coil installation requires fewer coupling joints (fittings). In addition, no solvent, chemical, or solder joining is required, saving times and effort.

*Warranty: As a statement to conceptPEX® quality standards, the conceptPEX® pipes carry a 10 year warranty for any manufacturing faults in all pipes.

cut is made.•Use a level for correct positioning of Elbow Box.•Select the right size screw brass fitting according to the pipe size. Put the nut on the pipe. Make sure the female side of the nut and the pipe end are on the same side. Slide the compression crimp ring over the pipe.•Do not apply lubricant or pipe dope on the insert fitting. •Position crimp ring 3 to 6mm from end of tubing. To prevent ring from moving, squeeze the ring slightly with spanner.•Keeping both ring and tool square with tube. DO NOT CRIMP TWICE. It is recommended that each crimped ring be checked with the appropriate gauge.

PEX Piping Supports•Plastic Brackets and or straps can be used. Supports that damage the pipes should not be used. Support should allow free pipe movement.•Although metal supports which are designed for use with plastic pipes can be used, but should be avoided. In any case, all supports should be inspected for sharp edges before use to ensure that they do not damage the pipe.

conceptPEX® pipe allows easy and quick installation of sanitary and heating systems.When installing it is necessary to follow the simple instructions referring to the connections of the pipes with the proper adaptors, bending of the pipes, protection from sun rays, and possible damages of the pipe or the protective sleeve by cracking.

•The connection to manifolds or to sanitary connections for the taps must be done using adaptors in the correct size.•In order to make a correct connection, it is necessary to cut the pipe precisely and perpendicularly to its axis by the proper cutter.•Pliability of the pipe is only guaranteed when the bends have a minimum radius eight times more than the outside diameter of the pipe.•Do not heat the pipe with naked flame or any other heating sources with high temperatures, as this will cause the pipes to melt.•Upon the completion installation of the pipe it is recommended that the system be pressure tested to ensure there are no leakages. •After the pressure test, the sleeves must be protected by covering them with concrete, to avoid cracking the pipes and movement of the installation.•Where the pipes are visible they must be protected against ultra violet rays, capable of altering the chemical-physical features.•When the pipe is installed without the protective sleeve, it must be covered by a screed of at least 1.5 cm, to avoid fissures due to expansion of the pipe.•In case the pipe is damaged due to incidental causes and must be replaced, traction fitting article must be used.

It is widely recommended that in order to established a consistent and leak free joint, it is necessary to follow conceptPEX® jointing procezdure for screw fittings.•Always use Special pipe cutters to cut and prepare the pipe. Make sure that a straight

by the following chart. The chart represents performance at 80˚C. The deterioration curves indicate life of the piping system, depending on the fluid pressure, temperature and hoop stress created in the pipe.Due to smooth pipe surface, conceptPEX® pipes have very low coefficient of friction compared to the metallic pipes. Moreover, no chemical reaction takes place between the pipe and calcium and magnesium carbonates in the water and no reduction in cross section occurs, thus giving constant pressure losses in long term use.
