Tanks began to be used after 1990 years in our country. With the spread of natural gas, the use of these tanks has increased rapidly. Today, almost every boiler room has a membrane tank. Membrane tanks have become a standard part of both heating systems and booster systems. In vehicles such as floor heating, it is directly integrated into the product. Closed expansion tanks, heating and heating systems to meet the volumetric change of the heated water, regulated by the static pressure generated by the pump on the installation and is used to compensate for changes in the flow rate of water. Expansion tanks suitable for the system and selected correctly prevent sudden pressure changes in the system and extend the service life of the pump and installation elements. Due to the hygienic membrane used in its production, expansion vessels are safely preferred in both heating and sanitary installation applications. Tanks and expansion tanks are designed to be compatible with each other. The water is contained inside the membrane but does not come into contact with the tank in any way. Therefore, tanks are used in both heating and cooling systems and sanitary installations.
Pressure vessels meet the needs of workplaces in hot water, steam, heat transfer, compressed air, transfer of pressurized water, sterilization and various processes. Many workplaces have pressure vessels and installations. The most commonly used pressure vessels are heating boilers (hot water boilers), steam boilers and steam generators, hot oil boilers, compressor air tanks, pressure boilers, expansion tanks, boilers, autoclaves, cooking boilers, paint boilers and so on. It shaped.
Pressure vessels should be manufactured in accordance with the standards, installation and installation in the workplace should be done correctly, regular maintenance and checks are made easier work and life. However, when manufacturing, installation, maintenance and controls do not comply with standards and techniques, they are a major source of danger: they may cause fires, burns, explosions, electric shocks. PERIODIC CONTROLS must be carried out in accordance with the Health and Safety Conditions Regulation on the Use of Work Equipment in order to operate pressure vessels and installations safely. Many business officials confuse PERIODIC CONTROL and PERIODIC MAINTENANCE and think that it is sufficient when they are serviced. However, PERIODIC CONTROL is a separate activity from MAINTENANCE as in vehicle inspections. Periodic Inspections include the control and testing of the equipment by technical personnel who are authorized by the Regulation and whether or not the equipment is operating in accordance with the occupational health and safety rules.
Mechanical engineers, technical teachers graduated from mechanical or metal department, mechanical technicians and high technicians are authorized to carry out periodic checks of pressure vessels and equipment. Periodic checks should be carried out at the latest 1 year intervals. Significant changes to equipment, accidents, etc. In cases, 1 periodic controls should be renewed without waiting for years. With the spread of natural gas in our country, the use of membrane tanks has started to increase. Today there is one membrane tank in all boiler rooms.
Pressure vessels and expansion tanks are explained in the annex (Annex 3) of the Regulation on Health and Safety Conditions in the Use of Work Equipment, titled matters related to maintenance, repair and periodic controls. In the hydrostatic tests to be carried out in the regular inspection and control of pressure vessels and expansion tanks, 1,5 times the operating pressure is applied, unless there is a contrary criterion in the standards. In addition, these controls should be carried out at least once a year by mechanical engineers, machine technicians or high technicians.
Periodic controls of expansion tanks are based on the above mentioned regulation as well as the pressure equipment regulation, the portable pressure equipment regulation and the simple pressure vessel regulation.
