The adhesive middle layers join the aluminum and PE-RT layers homogeneously. The PE-RT used for both the outer layer and the inner layer is type II, which is of the type with superior mechanical properties as defined in the ISO 24033, ISO 22391 and DIN 16833 standards. The aluminum layer provides a safe barrier against oxygen and other gases along with an outstanding resistance to crushing. Multilayer pipes R977 are fit for domestic water, heating and cooling systems according to standard EN 21003.

All fittings include a separator that insulates the pipe aluminum from the fitting to prevent galvanic corrosion.  NOTE. Given the wide range of fittings available, we recommend referring to the latest version of our catalog for sizes and product codes along with the corresponding range of application.  Thermal expansions Always take into account thermal expansion for planning and installation of PE-RT/Al/PE-RT multilayer pipes. Use the chart below to carry out proper evaluations. Thermal expansion can be determined by applying the formula ∆l = αa x L x ∆t where:

• ∆l = expansion expressed in mm
• aα = linear thermal expansion coefficient corresponding to 0,026 mm/m K
• L = pipe length expressed in m
• ∆t = temperature variation expressed in Kelvin [K] or Celsius [°C] degrees PIPE LENGTH [m] TEMPERATURE DIFFERENCE [K] 10 20 30 40 50 60 70 80 1 0,26 0,52 0,78 1,04 1,3 1,56 1,82 2,08 2 0,52 1,04 1,56 2,08 2,6 3,12 3,64 4,16 3 0,78 1,56 2,34 3,12 3,9 4,68 5,46 6,24 4 1,04 2,08 3,12 4,16 5,2 6,24 7,28 8,32 5 1,3 2,6 3,9 5,2 6,5 7,8 9,1 10,4 6 1,56 3,12 4,68 6,24 7,8 9,36 10,92 12,48 7 1,82 3,64 5,46 7,28 9,1 10,92 12,74 14,56 8 2,08 4,16 6,24 8,32 10,4 12,48 14,56 16,64 9 2,34 4,68 7,02 9,36 11,7 14,04 16,38 18,72 10 2,6 5,2 7,8 10,4 13 15,6 18,2 20,8 LINEAR EXPANSION [mm]

• Working temperature (TD): working temperature provided for the range of application, expressed in °C.
• Max. working temperature (T MAX): the working temperature highest value, allowed only for a short time.
• Failure temperature (TFAIL): the highest temperature possible when control systems fail (the time allowed for this value is 100 h over 50 years of uninterrupted operation).

• keep the pipe in its package and store in dry roofed areas to prevent damages caused by humidity;
• do not expose to direct sunlight;
• always cut the pipe to be installed using the special tools that provide a clean cut, 90 degrees to the pipe axis and free of burrs;
• after each cut, and before assembling the fitting, carry out the calibration using the special tool and lubricate the seals on the hose connection;
• prevent ice build ups inside the pipe as expansions caused by a change of conditions may damage it irreversibly;
• do not store the pipe at temperatures below -30 °C;
• never expose the pipe to open flames;
• after installation, carry out a pressure test at a pressure 1.5 times the working pressure.  Warranty The warranty shall be void when: 1) the working conditions vary from those provided for; 2) the pipe is used to transfer fluids not compatible with the construction material; 3) the installation instructions are not fully complied with; 4) the pipe shows visible defects caused by accidental factors upon installation or when the system is pressurized; 5) the pipe is installed using components not produced by Giacomini or different from the ones allowed.
