Flushing and crimping of heating systems

In the period of sharp temperature changes is very importantserviceable work of the heating system. It is the heat in the house that ensures the normal existence of its inhabitants. The elements of this system, which work under pressure, have some features of operation in difficult conditions.

Therefore, in order to prevent leakageradiator, pipeline breakthroughs and other troubles, it is necessary to resort to preventive measures. Pressurization of a heating system is a complex of measures, consisting in assessing the degree of availability of equipment for efficient operation.

The main requirements forheating of apartment houses and apartments, consist in uninterrupted operation and long-term operation of communications. The serviceability of the entire system is laid at the design stage, and durability depends primarily on the quality of service. It is the flushing and crimping of heating systems that will ensure a long service life of the coolant.

Importance of flushing heating systems

On the quality of heating and the efficiency of its supplyRust, scale, deposits of dirt and sand have a great influence. To eliminate the influence of these negative factors, there are two possibilities. First, increase the quality of the coolant to the required level. The second possibility is the crimping of heating systems, which is made regularly.

Improve the characteristics of water is difficult enough, and to carry out preventive work on cleaning pipes, radiators and boilers is quite within everyone's power.

Problems of the heating system

The scale that appears on the walls of the pipes causesmechanical wear of metal. Because of the deposits, the heat transfer of the pipes decreases, their diameter decreases. In this case, the friction of the coolant on the wall increases significantly, which causes a drop in the flow rate of hot water. Therefore, the temperature decreases due to thermal resistance.

All these consequences of the appearance of scale causeincreased fuel consumption. This will help increase costs, and the effectiveness of the systems will be constantly reduced. In this regard, crimping heating systems is an extremely important measure.

Preparation for works

Pressure is the main characteristic affectingto promote the coolant and the quality of heating the house. If the pressure is increased by more than 40%, a pressurization of the heating system is necessary. The pressure depends on the number of floors in the building (the higher the number of storeys at home, the higher the pressure level). Hot water moves through the pipeline under the influence of various hydraulic forces. For strong jumps, the pressure may exceed the permissible values. To avoid this, it is necessary to carry out preventive works.

Pressurization of heating systems begins withthe preparatory part. It is necessary to carefully inspect all components of the structure. To create tightness, gland seals are added. If necessary, the insulation of the pipeline is restored. After that, the building is cut off from the common heating system by means of plugs.

Crimping technology

Work begins with the filling of pipes with water. The system is connected to the water supply. The liquid comes under low pressure and pushes the air out of the device, filling all the nodes. The gas leaving the system should be lowered, and for several approaches.

To detect a water leak in an apartment building, it is necessary to produce air at a certain pressure. Therefore, the washing and pressing of the heating system is carried out with the help of a press.

The pressure drop during crimpingleakage and leakage. The place of failure can be various threaded connections, batteries, locking units and other elements of the system. It is necessary to find their localization, then partially or completely drain the water and repair the damaged areas.

The crimping of heating systems takes place until the working pressure is stabilized. To achieve its optimum value, special pumps are used.

Currently, there are three main technologies for washing the heating system. Each method has certain advantages and disadvantages.

Chemical flushing

The most popular ischemical Technology. Scale from pipes is removed with the help of reagents. The composition of such substances include solvents, alkalis, mineral and organic acids, complexones. Work with them must be very carefully, because they are very toxic.

Chemical flushing and crimping of the systemHeating is carried out by means of special equipment: pump, hoses and reservoir. A solution or powder for operation should be selected depending on the material of the pipeline. The work is done in several stages, lasting a couple of days. At the same time, the whole system continues to work, and the room receives heat.

The main advantages of this type are the simplicity of implementation, the extension of the service life of the pipeline and the complete restoration of the capacity of the heating system.

Hydrodynamic flushing

The essence of the method is to remove scale anddifferent deposits of water under pressure. The liquid enters the system through hoses connected with special nozzles. The effectiveness of this method is much higher than in chemical cleaning. But the cost of work increases.

Hydraulic flushing is optimal for cleaning cast-iron batteries. In this case, the use of chemical reagents will be less effective.

Pneumohydrolypulsive flushing

To carry out this method of cleaning, a special pneumatic gun is used. The tool is used for cleaning elements of the heating system with a diameter of less than 150 mm.

The technology of the method allows for purificationseparate nodes and remote sections of the pipeline. And you can work with a pneumatic gun at a distance from the object (up to 50 meters). The work is done very quickly and efficiently, without having to turn off the heat in the houses.

Equipment for work

The main tool for the workis a compressor that creates a pressure of water or solution. The range of devices on the market is quite wide, each unit has its own features and various functions. Therefore, the press for pressing the heating system must be selected correctly.

When buying a tool, you should pay attention toon the technical parameters of the device: water consumption, pulse pressure indicator and others. Also, you should consider the availability of additional functions, such as the possibility of adding disinfectants to the water.

The automation system of the compressor is also veryuseful. If it is available, the work will be more secure, and the whole process will be under control. The unit must be compact and reliable, so that its use does not cause any inconvenience.

To avoid trouble with the heatingsystem, it is necessary that specialists regularly carry out preventive work. To perform all the necessary actions, it is necessary to conclude a contract for crimping the heating system, which will note all the features of the process, deadlines, costs and responsibilities of the parties. The procedure should be performed in the summer, at least once every 5 years. And then the heating in the house will be served without interruptions and lining.
