What is EN ISO 14620-1:2019?

EN ISO 14620-1:2019 is a technical standard that provides guidelines for the design, fabrication, and installation of welded aluminum and magnesium alloy tanks used for the storage of flammable liquids. This standard aims to ensure the structural integrity and safety of these tanks.

Designing Welded Aluminum and Magnesium Alloy Tanks

The design of welded aluminum and magnesium alloy tanks involves several key considerations. Firstly, the material selection is crucial, as it affects the tank's resistance to corrosion, impact, and thermal stress. The standard specifies the requirements for the composition and mechanical properties of these alloys.

The design should also take into account factors such as the tank's capacity, shape, and intended use. Proper calculations and analysis are required to determine the necessary wall thickness, reinforcements, and weld details. Additionally, considerations must be given to the tank's supports, lifting attachments, and pressure relief systems.

Fabrication and Installation Process

The fabrication process of welded aluminum and magnesium alloy tanks follows specific procedures outlined in the standard. It covers aspects such as cutting, forming, welding, and inspection techniques. The welding process must comply with relevant codes and standards, ensuring proper joint configuration, filler material, and heat treatment.

During the installation phase, careful attention must be paid to factors such as positioning, alignment, and connection to the related piping system. Adequate handling, transportation, and protection measures should also be implemented to prevent any damage to the tank or its components during transit and installation.

Ensuring Compliance and Safety

To ensure compliance with EN ISO 14620-1:2019, regular inspections and testing are necessary. These involve checking the quality of materials, welds, and coatings. Additionally, non-destructive testing methods, such as ultrasonic or radiographic examinations, may be utilized to detect any potential defects or discontinuities.

Proper maintenance and periodic inspections are essential to ensure the ongoing safety and reliability of welded aluminum and magnesium alloy tanks. Any necessary repairs or modifications should be carried out in accordance with the standard's guidelines to maintain their structural integrity.

In conclusion, EN ISO 14620-1:2019 provides comprehensive guidance for the design, fabrication, and installation of welded aluminum and magnesium alloy tanks used for storing flammable liquids. By following these guidelines, manufacturers and users can ensure the safety and durability of these critical storage systems.
