Safety and pressure reducing devices are those devices that activate and reduce the pressure to the permissible values if the limit is exceeded. The most common ones are safety valves, bursting discs, deflection bars or controlled pressure relief systems. Containers and equipment with internal pressure above the 0,5 bar are called pressure vessels. The most commonly used pressure vessels, compressors, pressure boilers, boilers, gas cylinders, pipelines, air tanks, LPG tanks, industrial gas tanks, refrigeration units and autoclaves.
Automatic pressure relief systems are systems that operate when the set pressure is exceeded, close the pressure vessel partially or completely and allow the necessary interventions. Pressure vessels pose a number of risks to human health and safety. Therefore, necessary precautions should be taken beforehand.
In order to use pressure vessels together with safety devices without causing danger in terms of occupational health and employee safety in the enterprises, these containers should be checked and inspected regularly. In these studies, sealing, corrosion, wear, thickness, deformation, scratches, connections and calibration status of the devices are checked.
The main risks of pressure vessels are explosion hazard, risk of fragmentation after explosion, fire hazard, danger of suffocation and poisoning for human health and chemical and thermal burns.
In order to avoid these risks, depending on the usage of the pressure vessels, there must be measuring devices on them that show the pressure level and temperature inside. For example, manometers, thermometers, safety valves, relief valves, explosion covers and expansion valves are used for this purpose. The ability of these safety devices to perform exactly as expected depends on their regular maintenance.
The Health and Safety Conditions in the Use of Work Equipment issued by the Ministry of Labor and Social Security includes safety criteria, inspection periods and related standards for pressure vessels.
Our company conducts regular checks and inspections of pressure vessels safety devices within the scope of regular controls of pressure vessels in accordance with the relevant legal regulations and standards published by domestic and foreign organizations.
Pressure Vessel Safety Device Inspection and Inspection
Features of Pressure Vessel Safety Devices
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 in such a way that it shall never seize.
Since pressure vessels are equipment that poses serious hazards to human and property safety, it is necessary to have the safety devices on which they should be regularly checked and inspected in a timely manner.
Control and Inspection Principles of Pressure Vessel Safety Devices
All pressure receptacle safety devices must comply with the specifications of the pressure receptacle, be operational, the indicators must show correct values and comply with the requirements 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.
