Expansion tanks are vehicles operating under pressure and pressure points always cause danger and damage to people's life and property safety. The fact that these are not regularly checked using timely and correct methods carries the risk of explosion at unexpected times. It is used to meet the need for mains water or pressurized water from tanks in cases where the mains water pressure is insufficient in high buildings. In short, we can say that water pressurization systems are used in places where water pressure is not sufficient. These systems, most of which are powered by electricity, increase the pressure of the water flowing from our taps. Expansion Tank; The expansion tank (expansion tank) is used to prevent the pipes and mechanical parts in the system from being damaged by high pressure of the excess water generated by the increase in the volume of heated hot water in central systems.
When water is pressed into these tanks, air is compressed and pressure increases. Thanks to the increased pressure, the more water is pushed out. In the absence of booster tanks, an air compressor is used. They are generally used in buildings, workplaces, business centers, hotels, villas. Pressure tank controls, which are the main function of the booster system, must be carried out.
The controls of the booster tanks are subject to the ve Health and Safety Conditions Regulation on the use of Work Equipment ”. Femko, which is a Type A inspection body, is periodically controlled according to the issues and standards specified in this regulation.
Turcert Inspection helps you to prevent any dangerous event and to meet your legal requirements by presenting the deficiencies, nonconformities or dangerous situations as a result of the Hydrophore tank controls performed with its expert team and equipment in a report.
Boosters are used since the pressure of the city water network is not sufficient to meet the water requirements of buildings with multiple floors. Pressure boosters are pumping systems that automatically operate and compress water with low and low levels of pressure to the desired height. The air compression process is provided by the pump, the tank and the auxiliary elements found thereon.
Pressure booster auxiliary equipment located on the air tank are valves, check valves, safety valves, air injectors, air water pumps or a compressor, pressure switches, manometers.
There are various types of booster pumps. Some hydrophores supply the air themselves. Hydrophores, which are a part, use an air compressor for this. In some booster tanks, a membrane is used to separate the air and water zone from each other. In general, the membrane is a pressure resistant rubber. Membrane hydrophores are advantageous because they are cheap and take up less space, but because the pressure switch and the pump are switched on and off very often, failure occurs and the failure conditions are high.
Expansion tanks, boilers, central systems and combi boilers. When the hot water volume increases, excess water starts to form. If this excess water is not controlled in one place, high pressure builds up on the pipes, radiators and other mechanical parts on the hot water system. This will cause water to escape from the weakest point. The expansion tank is the tank that holds the excess water that is heated and prevents the increase of the water pressure in the system. Particularly the most important part during boiler maintenance is the expansion tank.
Expansion Tanks are similar in structure to booster tanks. They are generally connected to hot water boilers. Excess volume of water due to expansion by heating is stored in the expansion tank. The tank has a pre-pressure corresponding to the installation pressure. Thus, the system pressure is balanced. Excessive pressure in the installation due to expansion is prevented.
Expansion tanks are also used in heat exchanger systems for similar purposes. They are found in chiller air conditioning systems as “balancing tanks”.
Expansion tanks are also considered pressure vessels when they have internal pressure on the 0,5 bar and their periodic checks are mandatory. Periodic inspections of expansion tanks should be carried out by the Mechanical Engineer, Mechanical Technician or Mechanical Technician at least once a year. If NDT methods are preferred, controls may be performed by engineers, technicians or technicians with appropriate Non-Destructive Testing certificate.
According to the Regulation on Health and Safety Conditions in the Use of Work Equipment, which entered into force in 2013, the booster and expansion tanks shall be inspected and inspected at least once a year unless another period is stipulated in the relevant standards.
The following standards must be taken into account in these inspections, which must be carried out by mechanical engineers, machine technicians or high technicians:
- TS 1203 EN 286-1 Tanks - Simple - Non-flammable - Pressurized - Designed to store air or nitrogen - Part 1: Pressure tanks for general purposes
- TS EN 1012-1 Compressors and vacuum pumps - Safety rules - Part 1: Air compressors
- TS EN 13445-5 Pressure receptacles - Non-contact - Section 5: Inspection and testing
