Installation of polypropylene pipes with his own hands , manual, welding process

Modern polypropylene pipes are becoming increasingly popular, both among ordinary users and specialists.Due to its characteristics, these products are ideal for creating water and heat supply systems of varying complexity.Do not forget that they will last much longer than any other pipes - more than 50 years.Install the system is not difficult to polypropylene, it is only important to follow some rules when working with them to prevent errors.In addition, an independent installation will allow you to save a considerable amount of money for other needs.

What do the markings on

pipe When selecting pipe is taken into account, for what purpose will be used by the system, what temperature and pressure they have to withstand.It is because of this, it is necessary to purchase a particular product. There are four classes of pipes specified destination system.

type PN10 is only used for cold water;

type PN20 withstands high temperatures and can be used for both hot and cold water;

type PN20 exclusively for heating or hot water;

type PN25 is mainly used for heating mains

types PN20 and PN25 have a shell made of fiberglass or foil.This data pipe can withstand exposure to high temperatures.You should also pay attention to the surface.It should be free of burrs, other irregularities or defects.To cut the pipe must be perfectly round, with a smooth surface.Connect fitting and tube in the normal state is not possible.For connecting them is heated, and in this case the force needed for the connection.

Creating a system of pipes

Before mounting the water supply system, make a detailed layout of the system components.At the same time, special attention should be paid to saving space, the absence of superfluous elements or bends.They are fundamentally different in the installation of water supply and heating systems.

laying water pipes

Plumbing homes connected to the general water supply artery for the delivery of water to specific sites, such as faucets, household appliances, water heaters.This connection system can be both open and closed (hidden).This system is much more complicated and its installation requires certain skills and experience.

Reconfiguring existing hidden aqueduct is also associated with certain difficulties and require maximum precision, since it requires access to the interface of the system components.In the case of an open installation of the pipe system are located in the corners of the premises so as not to attract attention.

There are three types of installation of water supply systems.

1. · The easiest-to-use option - connection with a collector;
2. · The most popular due to its low price is a consistent water supply system;
3. · The rarest species - the system throughput outlets.

heating device

heating system project in the same way as the water system should have a listing of alldetailed parts and the location of all nodes including joints, couplings and the mounting system.It is necessary to determine where there will be heating radiators and how they will be fed pipe.Connect the radiators can be one or two pipes.Pipe connection with a radiator may be in a sidewall or bottom.

process welding polypropylene pipes

Before welding the pipe, you need to cut them into pieces of desired size.The required length of the note marker, after which a special tool for cutting pipe cut them and clean up the ends, if the product is reinforced or any other shell.Thereafter the tube is sealed by special soldering tool to polypropylene tubes using teflon nozzles of different sizes for pipes and fittings.These nozzles are located on different sides of the soldering tool.

Stages welding polypropylene pipes

included and ready-to-use tool has a temperature of 260 degrees.When the soldering iron reaches operating temperature, the Teflon packing wear pipe and fitting and begin heating.The heating time is determined by the diameter of products.Usually it is needed 10-15 seconds, then remove the product quickly with a soldering iron and combined to stop when connecting takes some effort, but in spite of this movement should be smooth.Rotating parts on the axis in the process of welding is prohibited, to avoid damage ..

Due to the heating parts are easy to bend for a while.In order not to damage the pipes, they should be placed on a flat surface as long as the product temperature decreases.At the end of the welding process you have to be integral and indivisible part, consisting of pipe and fitting.

Tools required.What you should know

If you decide to install the system yourself, you must have:

1. · adapters are required to connect pipes of different diameters ;
2. · couplings for welding pieces of pipe diameter ;
3. · couplings with male or female thread
4. · nipples to create the tap from the main channel and the connection with the pipe smaller diameter;
5. · Corner and simple tees for pipes breeding ;
6. · Crosspoint connectors ;
7. · plug ;
8. · connectors to different connectors (hoses, other pipes, fittings, etc.) ;
9. · clamps for fixing pipes on different surfaces and structures ;
10. · taps .

First mounted the most important elements of the heating network - heating radiators, heating boilers and plumbing elements.the next step is placed laying line pipes.Across the line set elements for fixing, after which all the elements are combined in a single system.In remote places assembling pipes produced as a separate step.All connections are made easily accessible locations with the use of the coupling, normal or threaded.

Mounting a pipe for heating systems and hot water systems, we should not forget that the pipe under the influence of temperature will be expanded.To compensate for this effect, a special kind of connection elements - the movable mount.After installing and checking all the connections you need to let the system has approximately one hour to rest and only then can we start filling the system.Before the hydraulic test, wait about a day to detect any leaks, deficiencies or errors in installation.

main advantage of polypropylene pipes - their long life and ease of use.Installation of polypropylene pipes may initially scare its complexity, but in fact it is a delusion.You only need to take into account some special features when working with polypropylene.Alternatively, you can easily find a specialist who will perform all the necessary work for you, as it is how well the system is assembled, it will affect its life
