Matters to be Considered in the Installation of PPR Pipes and Fittings
  • The installation should be properly tested with 1.5 times the system pressure (20 bar).
  • For bends over 30°, a 45° bend should be used.
  • Pipes should not be cut with any tools other than pipe scissors.
  • After the installation is installed, UV rays coming on the installation should be isolated.
  • Avoid pipes and fittings from direct sunlight. Keep the materials indoors.
  • Hard impacts can cause invisible capillary cracks in PPR pipes and fittings.
  • Therefore, it is necessary to be careful during assembly and transportation.
  • Do not use products whose outer surface is deformed for some reason.
  • Use after cleaning the products that are dirty during installation or have gotten dirt inside the pipe.
  • During the assembly of fittings, tighten metal products when dark:
  • Do not use fire to shape the pipes. Continue with the required additional parts.
  • We recommend that you use Teflon during the assembly of additional parts.
  • Welding should be done by taking precautions at temperatures below + 5C. In welding performed at low temperatures, the material hardens and its crystal structure deteriorates and a smooth welding will not occur.
  • Sudden temperature changes may cause cracks in pipes and fittings. • Since polypropylene materials are flammable, keep them away from fire.
  • If mounting with clamps, expansion and directional changes should be calculated.
  • If the pipe length to be applied is long, bending and bending calculations should be made.
  • Pipe clamps should be mounted in a way that does not prevent expansion.
  • The water in the system must be drained in freezing temperatures. Otherwise, there may be cracks and explosions in the pipes. After the installation is completed, a test must be done before starting the system.
  • Plastherm pipes should only be assembled with Plastherm fittings. Products of different brands should not be used.

Important Technical Issues in PPR Pipes and Fittings
  • Flexing Pipe and Its Calculation
  • Fixed Support and Calculation Clamp Distances
  • Pipe Bend Diameter insulation
  • Pressure Test
Flexing Pipe and Its Calculation Due to the structure of the polypropylene material, if the pipes and fittings produced are heat treated, there will be some expansion and elongation. By making the calculation we have shown in the PPR pipes expansion section, the application should be made so that the pipe expands in one direction. If it is not possible to plan the expansion in one direction, a flex pipe should be added. These can be pieces like bows. (Figure 1) The flexible pipes can be easily used for this process and the system is guaranteed by minimizing the possible errors in the installation. The free bending part length (Ls) can be calculated by the formula or confirmed from the graph in figure 2. For straight installations with a length of more than 5 m, calculations should be made using the formula and the necessary stretch pipes should be used. Elongation calculations in pipes should be done as follows: Fixed Support and Calculation Fixed supports placed in certain places prevent unwanted expansion by keeping the pipe fixed. At these points, the support resistance should naturally be made stronger than sliding supports. Fixed supports can be made by means of additional parts. However, fixed support cannot be made in the turning parts and direction changes should be made inside the pipe. Fixed points should divide the piping into sections that will allow or not prevent expansion such as elongation and shortening. Generally, expansions such as elongation and shortening are provided by parts such as bows. In Figure 4, the principle is illustrated as a diagram. The formula used is as follows: (∆I = xLx At) (mm) ∆l = Elongation amount (mm) ∆t Change in temperature ("C) L = Pipe length (m) = Coefficient of expansion (mm/mk), Clamp Distances Many factors such as the type, diameter, wall thickness, weight of the pipe and the temperature of the water to be used in the system are effective in the clamp distances of the pipes applied horizontally in Plastherm PPR pipes. These factors are calculated and the approximate clamp distances are given in the tables below. In addition, in installations to be applied vertically, the clamp distances are 1.3 times the horizontal calculations. Clamp Distances in PPR Pipes Clamp Distances in Foil Pipes Clamp Distances in Glass and Fiber Pipes Tube Bending Diameter Polypropylene pipes can be bent using hot air (140 ° C) only. Only in this way can it be used by making the insulation of the pipe flexible. No action is taken by direct exposure to the flame. Polypropylene material is flammable and combustible. Recommended approximate bending radii are given in the table below.
Considerations About Insulation in PPR Pipes
Metal or galvanized installations require more filling material and insulation than polypropylene installations. Polypropylene materials seem to be self-insulated because of their low thermal conductivity. There is no need for isolation under normal conditions in PPR installations made inside the building. This self-isolating condition is the biggest factor in minimizing the wall thickness of the pipe and the reinforcement materials used, glass fiber and aluminum foil, to the heat conductivity. However, the place where the system is laid and the size of the system are also very important. Insulation is required to prevent frost and heat loss in hot water pipes. If the installation is made in the external environment or if a part of the system passes through the external environment, that part must be isolated and protected against frost in the winter months. Likewise, if the hot water installation is to be applied longer than the calculated one, the places where the hot water installation passes should be isolated with filling or insulation materials in order to prevent heat loss. It is necessary to take measures against weather conditions in the pipes laid outdoors. Insulation materials will also protect the pipes from external factors. Approximate calculations of the insulation to be made in PPR, foiled and glass fiber reinforced pipes are given in the tables below.

Final Stage Pressure Test
  • After the hot or cold water installation application is completed, it must be subjected to a pressure test. This test should be 1.5 times the pressure to be used. It should not be forgotten that the factor affecting the pressure due to the expansion in the pipe as a result of the temperature change in the environment. A temperature change of 10 ° C creates a pressure difference of 0.5 to 1 Bar in the system.
  • After the installation is completed, the system is filled with water and pressure and leakage tests are performed. The air of the system is automatically taken with the intermediate element parts placed at the end or the top points of the system, or the system is pressure tested with the pump after the end points of the system are closed with a blind plug.
  • Pressure test consists of 3 stages. In the first stage, 30 minutes to the system. It is tested with a pressure value of 1.5 times throughout. Meanwhile, every 10 minutes. The system pressure in it is reduced to its previous state and increased again to the value 1.5 times. Pressure drop up to 0.6 bar or it should not be ascending so that it is understood that there is no leakage or leakage in the system.
  • In the second stage, the same process should be done for a longer time. It takes approximately 2 hours.
  • In the last stage, the resistance and strength of the system are measured by applying the same test in a much more series between 1 and 10 bars. This is based on sudden changes and the pressure test of the system is positive if there are no leaks or leaks in the system.
  • These tests should be done with a pressure measuring device with an accuracy of 0.1 bar.
