In 2007, the Pressure Equipment Directive (97 / 23 / AT) was issued by the Ministry of Industry and Trade. This regulation regulates the design, production and conformity assessment principles of pressure equipment and equipment with the highest permissible PS pressure of 0,5 bar. Pursuant to this regulation, which is prepared based on the 97 / 23 / EC Directive on Pressure Equipment issued by the European Union, the safety of people, animals and goods should not be endangered if the pressure vessels are properly installed, maintained and used for the intended purpose. In order to do so, the persons concerned must take the necessary measures.
According to the current legal regulations, all pressure vessels and their materials and equipment must be manufactured and used in accordance with the requirements of science and technique and the conditions of the work to be used.
Depending on the purpose of producing and using the pressurized container, there must be a number of measuring devices on the pressure vessels showing the pressure level, temperature and water level inside. These devices must have a manometer at the head, for example, which indicates twice the maximum operating pressure of the boiler. The maximum operating pressure on the pressure gauge on the pressure gauge must be marked with a red line. These marks must be large enough to be read easily from one and a half times the length of the boiler. Hot water boilers must have a thermometer to indicate the temperature of the water. Boilers should have at least two separate water level indicators indicating the water level. The water gauges should be directly connected to the boiler and showing the highest and lowest water levels.
Each valve must be fitted with a valve suitable for the boiler pressure. All indicators should be visible from the side and front of the accident under normal operating conditions.
Pressure vessels must also have a safety valve separate from these measuring devices. For example, steam boilers must have at least two safety valves. These valves shall be adjusted to the working pressure of the boiler and shall be made of stainless material so as not to cause any seizures.
Since pressurized vessels are the equipment that creates serious hazards for human and property safety, regular inspections and inspections of the safety devices which should be present on them should be done on time.
Control and Inspection Principles of Pressure Vessel Safety Devices
All pressure receptacle safety devices must comply with the specifications of the pressure receptacle, be in working condition, the indicators shall show correct values, and shall comply with the conditions and standards described in the relevant legal regulations.
Safety-related criteria, inspection periods, conditions and related standards are listed in the article entitled Pressure Vessels and Installations in the Regulation on Health and Safety in the Use of Work Equipment, which was introduced to the year 2013. Pressure vessels included in this scope are: steam boiler, hot water boiler, hot oil boiler, hot water (heater) boiler, autoclave, air tank and compressor, pressure tank, fuel oil tank tanker, industrial gases land tanker tank, industrial gas storage tank , tanks and tanks containing dangerous liquids, pressure vessel safety device (safety valve).
The pressure vessel safety device or safety valve is the gas-releasing valve assembly when the highest temperature or pressure detected in the pressure tank and other systems is reached. It is used to ensure safety in boilers and tanks.
As many test and inspection organizations TÜRCERT Technical Control and Certification Inc. provides periodical control and inspection services for liquefied petroleum gas tanks. Our organization has a competent manager and employee staff and a strong infrastructure in this field.
