EN13480

EN13445 is a European standard for unfired pressure vessels, while EN13480 is a European standard for metallic industrial piping. They both cover similar domains (pressure equipment) and can be considered competitors, as companies may choose one over the other depending on the specific application and regulatory requirements.

ASME (American Society of Mechanical Engineers) standards, particularly ASME B31.3 for Process Piping, are widely used internationally and directly compete with EN13480 for industrial piping design and construction.
