what is better to put on heating polypropylene reinforced with fiberglass or aluminum? ? Thank you

  1. put pipes of polypropylene reinforced with steklovoloknom production plant cross.
    everyone is happy!
  2. well, as noted Pol_ekt - metal is certainly better.
    But of the two chosen by you - reinforced with aluminum.
    Fiberglass - for hot water, where the temperature is not constant.
    And in heating it is always the same.
  3. Neither one nor the other. Only steel.
    In the same with the santehs take even a subscription, - for heating only steel. On hvs-hvs please - at least plastic, at least copper, though propylene.
  4. If finances allow you to put shiny polyethylene, but for life
  5. I put parents in the private house with fiberglass.
    The only pipes that mostly have the properties of reinforced pipes and do not require stripping are the so-called glass fiber pipes. Such pipes have a three-layer structure with an average layer of compound (mixture) in which the premix of fiberglass and polypropylene is placed. That is, in the process of welding, this layer from the end can also be welded, and even more so it will not enter into chemical reactions and corrode.
    Rubis Fiber Glass three-layer PP-R pipes, reinforced with fiberglass. Products are designed to facilitate the work of installers, significantly speed up the installation and save material. Areas of application: heating, air conditioning, technical and drinking water supply systems
    The color of fiberglass in polypropylene pipes does not matter and does not affect the quality of the products. This is a kind of marker that allows you to immediately recognize the products of a certain manufacturer.
    The aluminum layer has two varieties: with through holes and without them (the so-called perforated foil and smooth foil). The question of saving on the material, as it may seem, in this case is not the reason for the presence of holes. Simply on the surface of the pipe, reinforced with smooth aluminum, with the passage of time during operation on hot water, small swellings may appear. This is due to the fact that in the process of pipe extrusion and the laying of a metal layer under aluminum, microscopic water particles can remain, since the inner layer of the pipe passes the cooling stages in the water baths before being wrapped in aluminum.
    This defect is not critical, since the deformation affects only the outer layer of polypropylene and the layer of aluminum foil without even tearing them apart. The inner (main) layer remains untouched.
    Pipes reinforced with a perforated aluminum foil are almost completely devoid of this aesthetic drawback.
    Polypropylene pipes reinforced with perforated aluminum foil from the outer edge of the pipe
    Very rare cases of extremely small swellings on the surface of such pipes are very rare. Someone will say that the presence of a perforated foil can lead to the penetration of oxygen into the pipeline system, which is of no small importance in heating systems, since an excessive amount of oxygen in the coolant leads to accelerated corrosion of heating devices (radiators). But this issue usually disappears by itself if we mount polypropylene pipes reinforced with aluminum with perforation for heating systems of typical apartment buildings or we are engaged in replacing steel pipelines in such houses with polypropylene ones. Since in the absence of individual heat points (ITP), i.e. if there is a centralized heating system, the water mixed into the system usually does not pass through the degassing stage, but comes enriched with oxygen. Therefore, there is no difference in how the oxygen enters the system: through the wall of the pipe or from the heat point.
    There is a different solution to the problem of microexpanding of the outer layer of a reinforced pipe by reinforcing aluminum in the middle of the pipe, and not closer to the outer layer, as is customary. In this case, all problems with swellings and bundles will not be conspicuous to consumers.
  6. If the heating is central, in an apartment building, it is better to put steel. And only f. If your house, boiler, it does not matter, especially. But, it is useful to know that the glass fiber reinforced pipe has a much smaller linear expansion, in comparison with a pipe reinforced with aluminum foil. Spoon aluminum, I think, all lowered into a glass with hot tea. I know everything that happens to her. Cut a piece of fiberglass into boiling water - and it will be cold. (opposite end)
    The smaller the linear expansion of the tube, the better. In addition, glass fiber (pipe) is easier to work with. And the technology of production itself is more progressive, more modern. But this is all theory. In practice, with competent installation, if the aluminum pipe was cleaned, and where the aluminum in the middle - its special sharpener was cut-cut, each joint, as required by the installation rule, you will not see a difference. I do not advise a pipe with an outer reinforcement aluminum foil, if you choose aluminum, then only one that is in the thickness of the pipe wall. The pipe with external reinforcement is subsequently covered with water blisters on the heating, the foil layer is blown up. And although they, these blisters, have little effect on (so pipe manufacturers assure us) they obviously spoil aesthetics.
