Question answer

1. First of all, products of polypropylene sludge can boast of increased heat resistance (+ 95 ° C). Such pipes have demonstrated excellent performance and have proven themselves in hot water supply (including centralized). The permissible temperature indicator for PVC pipes is much lower (up to + 60⁰С), which excludes their use as elements of pipelines for the supply of hot water, heating.
2. Polypropylene pipes are more durable and have excellent indicators of wear resistance. In terms of service life, polypropylene products are significantly superior to PVC models. The reason for this is the insufficient reliability of the structure of polyvinyl chloride, as well as its poor resistance to various factors of influence. In addition, the lower smoothness and wear resistance of the surfaces of PVC pipes contributes to their slow destruction.
3. The advantage of Polypropylene pipes over PVC products is their great frost resistance. It provides materials with access to use at low temperatures up to -20⁰С. At the same time, the PVC material is not only unable to withstand a drop in temperature to the same level, but the possibility of installing pipes in severe frost is also excluded.

If we talk exclusively about color, then the color is due solely to the introduction of the corresponding color dye in the raw material. It can be white, gray, green, blue and any other dye. The dye does not affect product quality in any way and carries an exclusively aesthetic burden.

The service life of polypropylene pipes directly depends on several factors, namely: on the water temperature and the maximum allowable pressure for a particular type of water, as well as subject to the installation technology and operating requirements.

The service life of polypropylene pipes is much higher than that of structures made of other materials.

The recommended technology for soldering polypropylene pipes involves several stages.

1. The device must be installed on a flat surface so that it is easily accessible. The desired temperature is set on the control panel of the device, for polypropylene pipes it is 260 °. The device turns on and heats up, which takes about 10-15 minutes.
2. Using special scissors, the part is cut at a right angle. The cut point is cleaned and degreased with the fitting using a soap or alcohol solution.
3. Elements are put on nozzles of the device of the necessary diameter. The pipe is inserted into the sleeve to the limiter, showing the depth of welding, and the fitting is installed on the mandrel. The heating time of parts is strictly maintained. For each type of pipe it is different.
4. The heated parts are removed from the apparatus and are connected with each other with confident fast movement in compliance with the alignments of the elements. Connecting parts they can not be rotated axially or bent. It is also necessary to strictly monitor that the pipe enters to a depth defined by the inner boundary of the fitting's socket.
5. Preheated parts must be allowed to cool, this is especially important for thin-walled pipes. Any deformation of parts at this time is unacceptable, they can lead to sealing of the inner lumen of the pipe.

• The working temperature of polypropylene sewer pipes is +75 ° C (they withstand temperatures up to +95 ° C for 2 to 3 minutes). For PVC pipes, the upper limit of the withstand temperature is + 65 ° C, which limits the use of these pipes in sewage systems for hot drains (washing machines, dishwashers, etc.)
• Compared to PVC pipes, polypropylene pipes are stronger, especially at low temperatures, which plays an important role in transportation and installation in our climatic conditions.
• Polyvinyl chloride does not have the same molecular memory as polypropylene, therefore, as a result of deformations, PVC pipes poorly recover shape, unlike polypropylene
