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 PEX-b/Al/PEX-b 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]

• The connection of pipes to distribution manifolds or elbows for tap coupling must be executed using fittings and adaptors of the right size for that specific pipe.
• Pipe laying, fixing and connections have to be realized thus to avoid permanent mechanical stress on components.
• All materials used to manufacture pipes expand when they are heated and shrink when they are cooled: for this reason longitudinal change (ΔL) generated by temperature change should always been considered during installation. (see paragraph “Thermal expansions”).
• For surface installation, pipe length must be calculated on the basis of system requirements and distances between pipe supports must be carefully evaluated. Maximum distance between each support (L) depends on the diameter of the pipe used. L L PIPE EXTERNAL Ø [ mm] MAX. DISTANCE BETWEEN SUPPORTS (L) [ mm] 16 1000 18 1100 20 1250 26 1500 32 2000 40 2250 50 2500 63 2750 75 2750 90 2750
• Supports used in surface installations have the two key functions of supporting the pipe and allowing its thermal expansion. Supports can be fixed, clamping the pipe; or sliding, permitting the pipe to slide as a result of thermal expansion.  WARNING. Secure the pipe with the aid of plastic ties. Avoid using metal ties without protection, as they could damage the pipe. FIXED SUPPORT SLIDING SUPPORT

• In long straight pipe stretches, to absorb any length changes, it is advisable to insert at least one expansion bend every 10 m. For pipes with a diameter equal to or greater than 32 mm, expansion bends are mandatory. L Distance between fixed support and expansion bend ΔL Pipe longitudinal change F Fixed support Lb Lenght of the expansion bend L L ∆L ∆L FF F Lb/2 LbLb Minimum lenght of expansion bend (Lb) can be calculated with the following formula: Lb = C x √(Øe x ΔL) Lb = minimum lenght of the expansion bend in mm C = costant of material (for multilayer pipe the value is 33) Øe = pipe external diameter in mm ΔL = pipe longitudinal change in mm Example: L = 5 m Ø e = 25 mm α = 0,026 mm/(m K) ΔT = 60 °C ΔL = 5 x 0,026 x 60 = 7,8 mm Lb = 33 x √25 x 7,8 = 460 mm
• When bends are required, it is fundamental to use fittings and fix/sliding supports correctly, as per the following drawing, It’s advisable to fit an expansion bend each time the pipe changes direction also considering to have clearence around.

• 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;
• the bending radius during the laying of the pipes must be greater than 5 times the external diameter of the pipe;
• pipes were fittings have already been assembled must not be bent. If bending cannot be avoided for technical reasons, the area of the pipe near the fitting must not be subjected to permanent stresses;
• two consecutive fittings must be installed at such a distance so as not to generate reciprocal stresses on all components, both during system installation and operation;
• in installations pipe must always be protected from UV rays and fluorescent lights that could alter its chemical-physical properties;
• make sure the pipe is not exposed to solar radiation or fluorescent lights for long periods;
• if the pipe is chased without a protective sleeve, it has to be covered with at least 15 mm thick screed to prevent cracking of the plaster due to thermal expansion;
• avoid chasing fittings as much as possible. If this is not possible, make sure the fitting can be inspected or protect it from contact with building material and make a note of its position in the project documentation;
• after installing the pipes and before covering them, it is advisable to test the system under pressure, so as to immediately identify any leaks (see paragraph “Pressure test”);
• following the pressure test, the sleeves must be protected by encasing them with cement so that the pipes cannot be crushed or moved.  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.
