Proper installation and high-quality initial setup of heating equipment can not guarantee the full operation of the heating system. Any installation before use must undergo pressure testing. The process is a diagnosis that allows to find weak points. It is considered necessary annual pressure testing the heating system in an apartment or private home, where there is water heating. Otherwise, during the heating season may show unexpected problems that need to be corrected urgently.
What held crimping?
heating pressurization is Hydraulic testing of individual elements. This allows you to determine the integrity and investigate the possibility of keeping the operating pressure, including water hammer. The procedure makes it possible to learn about places leaks, and ensures reliable operation during cold weather.
In which cases is the process?
Tests are carried out on several occasions:
- a new system that has never been included;
- repairs;
- replacement of a single element;
- before you start the heating season;
Who spends?
In buildings with heating system, all operations are carried out by specially invited experts. If the system is mounted on its own, then check these too often carried out in the same way (again it is better to watch the video). In any case, you must comply with all the requirements of the tests, which are registered in the passport or equipment specified in SNIP.
How it is?
The order of testing depends on many factors, including the number of floors, wiring diagrams, material and more. Usually conducted hydraulic diagnosis, by injecting water. Often it happens and air - pressure is created by air.
Crimping in a private house
In a private house, regardless of size, heat crimping is an important procedure. If this is not done in time, in winter problems may occur, which will need to correct for the absolutely other money.
Standalone closed systems in most cases have a working pressure which falls within the scope between 1.5 and 2 atm. To create an additional, which can reach up to 4 atm., Can use electric or manual pumps. Sometimes an excessive pressure is generated by connecting to a normal water supply, as in a tube, this figure could be up to 3 atm.
Filling system is made by a special faucet which is at the bottom. Thus the possibility of air will rise up and out through special valves installed at the highest point on each battery.
Important! The temperature of water which will be poured, the mark should not exceed 45 degrees Celsius.
If the landlord decides to use the residential area the water for the diagnosis already as a coolant, it is It must remember that such a liquid must have a suitable rigidity, located within 75 to 95 units. The most successful example is the rain or melt water. If you can not accurately check this option, you can look at the inner wall of the kettle, or any other element of the heating fluid. Explicit scale appearance indicative of excessive concentrations of various elements.
If water with which conducted pressure testing, will not continue to be used in the system, it is necessary to immediately drain and fill equipment suitable coolant. This is particularly important if the wiring is made of a ferrous metal. Also, water with high stiffness adversely affects the radiators made of steel or cast iron.
How much pressure should be?
The pressure that is created in the tests depends on several key factors:
- the duration of use of the system;
- date of the last rinse;
- material pipes and radiators.
In the new system of indicators of pressure tests must exceed the operating pressure of more than two times. But in this operating mark may be from 20 to 50%.
Various pipes and radiators are designed for different pressure. It is considering this and the calculated maximum values, which are needed for molding.
Crimping heating, regardless of the building size, is an important procedure. If she ignored in the future, you may receive a lot of problems to solve that need to be in unpleasant conditions. In addition, it is likely to be spent much more money.
