Polypropylene for water supply

Types PP pipes

Industry produces polypropylene pipes of three types:

  1. pipes for cold water - PN 10;
  2. products, which is possible to provide both cold hot water - PN 20;
  3. used to supply heat-reinforced polypropylene pipes.

Types of PP pipes

diameters PP pipes

to connect the pipeline of polypropylene pipes using a special blowtorch.Given the diameter of the tip set for soldering, pick and diameter of the pipe.Standard size range includes the following parameters: 20, 25, 32, 40, 50, 63, 75 and 90 mm.

Installation of water using the aqueduct of polypropylene pipes perform the following sequence:

  • remove the old pipes of water supply;
  • cut pipe sections to length;
  • when connecting pipes using special coupling of different materials;
  • using a soldering iron with nozzles, assemble the circuit water supply system;
  • mounted crane valves;
  • stack assembled structure in the pre-prepared in Stroebe wall or drill holes for mounting fixtures on surfaces;
  • perform final assembly of polypropylene pipes for hot and cold water.

The diameters of the PP pipes

When connecting the metal taps and mixers for polypropylene pipes, fittings, their union produced with iron elements.To ensure a tight seal using special tape FUM, which is wound onto a threaded connection.The number of turns laying must not exceed two, as this may damage the inner surface of the threaded fitting.

If the scheme pipeline installation are twists and turns, they organize with the help of the corner fitting.You can also heat the part of the pipe hairdryer and bend it manually.It should be remembered that the polypropylene has a flash point at 350 ° C.

The diameters of the PP pipes

pipe PP pipes for the supply of heat or hot water has the property to expand when heated.Therefore, from the elbows or tees necessary to leave a part of the tube a distance of 1cm.

Pike polypropylene pipes

To make installation of polypropylene water pipe in the wall cut Stroebe, the amount of which shall be equal to the diameter of the pipe plus the insulation gap.Some of the pipes are connected to each other by means of solder sleeves.pipes made of polypropylene manufacturing technology provides for the presence of a metal braiding inside the tube.This solution allows to reduce the degree of expansion of the material during hot water or heating.In the manufacture of PP pipes for arranging the cold water supply does not have a metal expansion joint, and are much cheaper.

Technology soldering pipes made of polypropylene following:

  • on soldering iron tip wear appropriate diameter and begin heating pipe section.Tips for a blowtorch covered with a layer of Teflon, so they need to be cleaned only wooden tools;
  • to expose the soldering iron 260 ° C temperature and wait about 7 minutes to warm it up;
  • cut the required length of the pipe section at a right angle, and put on him a preheated clutch;
  • of the diameter of the polypropylene pipe depends on the heating time.On the free end of the nozzle wear tube, which is heated from the outside.Coupling warm on the inside;
  • Then elements are removed from the handpiece and inserted into each other, soaking time for fixation without moving.

holding time depending on the polypropylene pipe diameter specified in the table.
