4. GENERAL CHARACTERISTICS

4.1 THE MAIN FEATURES OF THE RANDOMKIT SYSTEM

• Potability: these pipes and fittings meet the requirements for drinking water systems;• Safety: the pipe and fittings are joined by polyfusion welding, which provides a safe operating system;• Easy handling: this is possible due to the low specific weight of polypropylene;• Low pressure losses: due to the smooth inner surface of pipes and fittings, so that no limescale or other deposits can be

formed;• Soundproof: absence of noise from fluid flow even at high speeds; • Resistance to chemical agents: provides excellent resistance to many chemical agents; • Reduced thermal conductivity: PPR is a weak conductor which has the effect of reducing condensation;• Lifetime of the installation properly executed and used is 50 years

6. PACKAGING. HANDLING. TRANSPORT AND STORAGE

• Pipes are delivered in bars of 3 or 4 m in plastic bags and the fittings in bags, and remain packaged until installation; • PP-R pipes are stored in their entire length so that they do not bend.• PPR pipes and fittings are stored in dry, clean and shielded areas of external stress like knocks and scratches. Do not throw

the pipes and fittings;• UV rays affect: PPR as all thermoplastic materials, should NOT exposed to sunlight;• Fragile at low temperatures: Pay attention to handling the pipes at temperatures below 0°C;• Scratched or cracked pipes due to handling or transport NOT to be used for installation.

7. THERMAL DILATATION

For the PP-R pipes that will be installed on the wall (visible pipes), the thermal dilatation and how to prevent an uncontrolled movement of them must be considered still from the design phase. For this it have to evaluate the direction and value of pipe expansion, according to temperature variations, which occur not only during the operating life of pipes but also owing to the difference among the four seasons and an expansion compensator with position of the fixed and sliding points. We suggest use of continuous horizontal supports for installation of horizontal pipes where possible or clamps according to pipe outside diameter and fluid temperature. Their expansion should be compensated between 2 fixed points by elbows, flexible arms or, where this is not possible, “compensators” should be fitted between the pipe and the structure.The fixed points of the system are positioned near the branches, valves or wall passages.The sliding points must ensure alignment of the installation, axial support and movement, preventing vibration and noise transmission.For the pipes installed inside the wall or the floor in protective tubes, contraction and dilatation are compensated in this tubes. The material of protective tubes is recomended to be soft, able to absorb pipe expansion and save energy. If the expansion might be excessive, and insulation thickness might not be able to control it, it have to calculate and make an expansion compensator. Please remember that pipes must be installed at an acceptable depth under the surface of wall or floor, in order to avoid cracks; besides, excessively too high internal tension due to stresses on pipe sections and on joints should be avoided.The variation in length of pipe according to pipe length and temperature variation shall be calculated using the following formula:

The thermal expansion coefficient has next value, depending on the type pipe:• monolayer pipe - PP-R α = 0.15 mm/m K (=1.5 * 10-4 K-1) • multilayer pipe PP-R/FIBER α = 0.045 mm/m K (=0.45 * 10-4 K-1)• multilayer pipe PP-R/Al α = 0.03 mm/m K. (=0.3 * 10-4 K-1)

ΔL = α x ΔT x L ΔL = L-LoΔT = T - To

where: ΔL = linear expansion [mm]Δt = temperature difference. [0K]α = thermal expansion coefficient. [mm/m K]L = length of segment under consideration T. [m]T = working temperature. [0K] To = installation temperature . [0K]

Calculation of the expansion compensator type "U"

PF : fixed point ; PM: sliding pointThe U-compensator is made up of 2 type L compensators, the length and minimum width are calculated with follow formula:Lc = 2 x ΔL + ms.Lc = minimum compensator width [mm]ms = safety limit of width = 150 mm

Example: PP-R d = 40 mm. L = 5 m ; T = 60 0C ; To = 20 0C

⇒ ΔT = T - To = 40 0C ; ⇒ ΔL = 0.15 x 5 x 40 = 30 mm ⇒⇒ Lc = 2 x 30 +150 = 210 mm

8. THERMAL ISOLATION OF PP-R PIPES

Thermal insulation for pipes is made according to DIN 1988 standard to avoid condensation for cold water installations and heat loss in hot water and heating installations.The thickness of the insulation is dimensioned according to the temperature difference of the environment and the water temperature flowing through the pipe, the air humidity around the pipe and the thermal resistance of the insulation to be used.The minimum thickness of the insulation layer, depending on the applications, can be appreciated according to the following tables:

9. INSTALLATION

Valrom range has a welding machines and tools for the pipework.

Recommendations for placement:

9.1 Mounting apparentlyEven in the design phase of the installation, the expansion of the pipe must be taken into account and it is therefore necessary to determine the position and size of the expansion joints as well as the mounting method of the installation. The pipe support should be continuously or with clamps.In locations where there is a risk of condensation. the PPR pipe must be insulated.

9.2 Assembly buried in concreteAssembly in concrete is possible because the piping is not sensitive to the aggressive action of the cement and for a safe operation of the installation it has to protect the piping in a protection tube to create the required expansion space and save the energy. The installation depth must be greater than or equal to 1.5 × the outer diameter of the tube. The threaded fittings do not mount in concrete.The pressure test shall be carried out before to pour the concrete.

ATTENTION! Observe the instructions for the use of welding machines and safety regulations

9.3 Pipes and fitting jointing by fusion recommended procedure The jointing between pipes and fittings is made by welding them together using a fusion welder; this acts in the points which come into contact, usually the external surface of pipe and the internal one of fittings. Special equipment is necessary: a fusion welding machine and some tools. Please refer to the manufacturer’s welding machines instructions and the safety regulations.

The operating sequences are following:

Preparing the welding machine:Fit the welding machine with the heating adapters of the diameters to be processed. The heating adapters must be clean and in perfect state.Connect the plug to the 220 V. 50 Hz power supply socket and set the polyfusion temperature indicated by the fittings producer by turning the thermostat on (for Valrom fittings 260°C). Turn on the welding machine. When the red light(s) of the machine is(are) off, the welding machine is ready to use.

Preparing the pipes and fittings for welding:Cut the pipe perpendicularly using the PPR cutting tool and free it from any residual burrs. Check that the parts to be connected are clean. The insertion length should be marked on the pipe with marker.

ATTENTION! In the case of PPR+Al (PPR with aluminum inserts) pipe, the aluminum layer must be removed with careful, if it remove more, the pipe diameter will be smaller, which leads to failed joint. After peeling, we recommend measuring the diameter of the pipe. If it is not correct (equal to the nominal diameter) cut off the piece of compromised pipe and repeat the operation more carefully. For the PPR+FIBER (glass fiber insert) pipe, this operation is no longer required.

19


Making the weld:Fit the pipe and the fitting simultaneously into the heating adaptor of the corresponded size, on the same axis and wait the heating time indicated in the table 1. After heating, quickly remove the pipe and fitting from the heating adapters and press them together up to the limit marked on the pipe joint without twisting them and are pressed all the welding time. Then allow it to cool down according to the recommended cooling time from table1..

After cooling time. check that there are no residues of molten material on the heating adapters after each welding operation.

Table 1

ATTENTION: The temperature of ambient and of the pipes and fittings must be minimum +5 oC in PPR welding procedure time.

9.4 Threaded joints • Use a teflon or similar to prevent escapes in metallic connections. Use only fittings with calibrated fillets and screw them without extreme effort.• The threaded fittings do not mount in concrete

9.5 Bending of PPR pipes• Do not use a blow torch flame to bend the pipe molecular structure of polypropylene could be damage.

• Minimum radius is external diameter multiplied by 8, see next table:

• A bend with radius less than 8x d can be achieved only with controlled air jet at 140 0C..• Changing the direction of the plumbing installation is better to do with fittings (different elbows) than by bending the pipe.

10. PRESSURE TEST

After the system installation is complete before the job is handed over. it is necessary to perform a pressure test to see if the installation has been performed correctly and there are no system losses.The pressure test is done with water. We do not recommend compressed air pressure testing.

10.1 Pressure test procedure according to I 9 and I 1The pipe for which the pressure test is to be carried out must be mounted to be visible and clean in accordance with the design. Valves can be mounted but they must be able to withstand the test pressure to which they are subjected, usually, when this pressure test is performed, shutters are used. The pressure test shall be carried out in accordance with the following conditions:• The maximum length of pipeline for pressure test is 100 m.• Fill the pipeline with 24 hours before pressure test.• The pipe is filled (at least to 2 hours after the last welding) from the lowest place as follows: open all the places through

which permit eject the air and close gradually as soon as water goes out wihout bubbles of air.• Test pressure is equal to 1.5 times the admissible operating pressure, but not less than 6 bar. In the water filled pipeline, we

raise the pressure slightly to the pressure test value.• Beginning of the pressure test is at minimum 1 hour after eject the air from installation.• Duration of pressure test: 60 minutes. During this period is must to check the pipeline and leakages must not occur at any

point in the system being tested.• Pressure loose maximum allowed is 0.02MPa (0.2 bar). If we have a decrease of more than 0.02 MPa means that there is a

fault (water loss) and this must be repaired

11.Disposal at the end of life time considerations

Waste treatmentWaste and products at end-of-life should be recycled as much as possible. Recycling is done on the thermoplastic container or by specialized firms.Methods for disposal of waste and packaging contaminatedThey will be recycled. Treating as domestic garbage is discouragedCommunity and harmonized waste legislationThe legislation in force will be observed
