Pressure tank safety standards and regulations

The pressure tank is one of the vital equipment in various industries such as oil and gas industry, chemical industry and petrochemical industry. In order to maintain safety and reduce the risks associated with fixed equipment, there are safety standards and regulations for the design, construction and operation of pressure vessels. In this article, we will review the standard and safety regulations of pressure vessels.

Related standards and regulations

ASME Section VIII standard in pressure vessel safety standards and regulations

One of the most important standards related to the pressure vessel is the ASME (American Society of Mechanical Engineers) Section VIII standard. This standard includes provisions and requirements for pressure vessel design, construction, and inspection. This standard is divided into four sections, each covering specific aspects of tanks.

API 650 standard in pressure tank safety standard and regulations

For liquid storage tanks, especially oil and its derivatives, API 650 standard is considered as one of the most important standards. This standard is provided by the American Petroleum Institute (API) and provides specifications for the design, construction and maintenance of tanks.

NFPA 58 standard in pressure tank safety standards and regulations

For gas tanks, the NFPA 58 standard provided by the National Fire Protection Association (NFPA) is used as a comprehensive guide to the safety and firefighting measures of gas tanks. This standard provides specifications for the design and installation of gas tanks.

EEMUA 159 standard in pressure tank safety standards and regulations

The EEMUA 159 standard (Engineering Equipment and Materials Users Association 159) is used to improve the performance and productivity of pressure vessels in process industries. This standard includes the requirements related to the maintenance, reconstruction and improvement of tanks.

The most important items in the standards

Design and construction materials

The standards specify exactly how the pressure vessel should be designed and what materials it should be made of. This includes criteria for material selection, wall thickness, and various connection methods.

Inspection and test

The standards provide detailed requirements for the inspection and testing of pressure vessels during construction and operation. This includes defining non-destructive inspection (NDE) processes and criteria for performing pressure tests.

Safety and fire protection

The standards seriously address safety and fire protection in pressure vessels. This includes things like installing fire extinguishers, coolers, and safety notices.

The importance of using standards

The use of standards and regulations in the design and construction of pressure tanks is very important because these standards have a significant protective role in preventing accidents and technical problems. Safety of personnel, environment and equipment are all considered as the main objectives of these standards.

New approaches in pressure vessel safety standards


Modeling and simulation

Among the new approaches in pressure tank safety standards is the use of modeling and simulation in order to more accurately analyze the behavior of tanks in different conditions. By using advanced modeling software, engineers are able to simulate the dynamics, heat transfer, and behavior of materials used in tanks. This action helps to improve the performance and stability of tanks and thus increase their safety.


New technologies in safety

Today, the use of new technologies such as sensors, nanotechnology and artificial intelligence to increase the safety level of pressure vessels is on the agenda. Automatic systems with the ability to detect and prevent accidents play an important role in the safety of these tanks.


risk management

One of the critical aspects of pressure vessel safety is risk management. With the help of risk management methods, the probability and effects of accidents are accurately evaluated and appropriate safety plans are developed. This approach helps not only to optimize the use of resources but also to make better decisions in the field of safety.

Challenges and improvement solutions

Due to technological advances and the need for greater safety, challenges have also arisen. Some of the challenges are:

Complexity of standards: standards require constant analysis and review due to the complexity of the content and continuous changes.

Costs: Implementation of standards and compliance with safety will lead to additional costs. Especially in industries that require a large number of tanks.

Training and maintenance: personnel training and timely maintenance of equipment are among the challenges that some industries may face.

To improve the above, it is necessary to conduct more research on new safety standards and approaches. Also, the participation of the industry and the development of advanced technologies can have a significant effect on improving the safety of the pressure tank.


Pressure tank safety standards and regulations play a very important role in the safety, optimal performance, and stability of these equipments. Correct implementation of these standards ensures the safety of systems and prevents serious accidents related to pressure vessels. Therefore, compliance with these standards at every stage of the construction of a spherical tank or a cylindrical tank under pressure is of great importance and is considered an important point in improving the safety and efficiency of systems for various industries.
