How practical polypropylene? Fittings and pipe made of polypropylene

Polypropylene in modern conditions is gaining more popularity. It has all the requirements of the relevant qualities, easy to install and is relatively low cost.

Therefore, more and more of the water supply system and heating is collected when using this material. Polypropylene fittings which connect with a soldering allows you to create a monolithic structure. It is no different in the joints from one piece of pipe.

However, fittings made of polypropylene it is necessary correctly to pick up for heating, sewer, water.

General notion fittings

Any system that transported water, consists of pipes and their compounds. This fittings. Polypropylene is a good choice.

In English the word "fitting" means "mount", "connect". They are used for folding the straight pipes, turning, branching. With their help, are the transitions from one pipe diameter to another.

Fittings and pipe for water supply of such material, such as polypropylene, can be welded. This happens very quickly when using the soldering iron nozzles. While the joints will not leak with high probability.

This property is one of the main advantages of. Today, demand for such fittings. Polypropylene is used throughout.

Dimensions

Manufacturers produce a wide variety of sizes of fittings. This makes it easy to find the desired kind. There are connections with thread and without it. They are chosen taking into account operation conditions.

If this is the fitting with thread, it can be split and whole. This should be considered when choosing the right size.

Polypropylene fittings which are often used in different systems, allows him a large number of different elements.

The Most frequently used dimensions are considered a part with a cross section 20, 25, 32, 40 mm. For arrangement of water supply system in high-rise buildings and they even use such a size as 110 mm.

The calculation of the diameter is adjusted to the length of the entire system. The bigger it is, the wider the pipes and fittings should be installed.

Range

The purpose of the different elements of the system. Have all sorts of configuration fittings (polypropylene).

Drainage, ventilation, or heating water used in their full extent. Pipes made of this material do not bend, therefore, to apply the compounds have, in any case. Sushestvujut:

• Mufti;
• Perehody;
• Stutzeri;
• Krestoviny;
• Zaglushki;
• Ugolki.

The Clutch will allow you to connect pipes of the same diameter, and the transition of different cross-section. Fitting will be required in case of necessity to connect communication with a flexible hose. The crosses serve to hold branches. Plug will allow you to seal stub pipe.

Accordingly, the positioning can be made using the area. Most often they are 45 and 90 degrees.

Marking

So I don't have a short time to perform the replacement of the pipes properly to pick them up. It is necessary to pay attention to labeling.

Pipes and fittings made of polypropylene for water supply is not suitable for heating. The marking is applied on all the details.

PN10 belongs to the thin-walled details to a cold feed water to +20 degrees. Working pressure is 1 MPa.

PN16 designed for cold water with high pressure.

PN20 suggests that the material can withstand heat up to +80 ° C and pressure up to 2 MPa.

For hot water and heating should be applied to items marked PN25. They are able to hold, heating to +95 degrees. At the same time allowed the system pressure can reach 2.5 MPa.

If the pipes for cold water to let the fluid with higher temperature, they will begin to deform. Therefore, even though the cost of different classes of pipe is very different, should only acquire the suitable parameters of the system fittings and pipe.

Advantages

Polypropylene Fittings for heating water have a number of advantages.

1. Light weight facilitates the process.
2. Long lifetime. In heating the polypropylene will last about 25 years, and in cold water communications - 50 years.
3. Relatively low cost.
4. Quick installation.
5. Aesthetic appearance.

All these qualities make the material so popular. Its popularity is increasing with each passing day. The fittings are resistant to corrosion and chemical effects. They are not deposited calcareous sediments, do not breed microorganisms.

Disadvantages

Fittings made of polypropylene for plumbing and other systems have a number of negative qualities. These include greater stiffness. They cannot be bent. Therefore the installation will require a large number of connections.

The disadvantages include the necessity of using special equipment. You should purchase it for holding the Assembly.

Polypropylene is also too sensitive to temperature rise. Because of this it can expand in diameter and extend linearly. For this material an important temperature.

However, these disadvantages pale in comparison to all the advantages. Soldering the device is not very expensive if you need to weld pipe at home. Professionals will quickly pay for the cost of expensive equipment for frequent use.

Installation

Polypropylene fittings which are used in the regeneration of various systems, involves the use of a specific Assembly technology.

This will need to buy a special soldering iron with nozzles of the desired diameter. It is necessary to cut pipe with a special scissors. Also prepare in advance the milling cutter, tape, marker.

For the Assembly electric soldering iron set temperature 240-260 degrees. With the help of a planer with the pipe removed the middle layer of the foil at 2 mm.

On the one hand the nozzle of the soldering iron is put on the pipe and on the other fitting. Aged heating time 3-5 seconds at the same time remove Them and produce a pipe joint with a fitting. Allow items to cool and test joint. This is a quick and relatively easy installation available even for beginners.

After Reading this material, such as polypropylene, fittings which today is very popular, you can collect different types of systems. Correctly picking up all items, and by assembling them properly, you can count on the long term operation of the system. Being one of the most commonly used materials, polypropylene has many positive qualities. Ease of installation, durability and low cost increase the demand for fittings from him.
