Final answer:
ASME tanks typically require a recertification every 5 years with more frequent visual inspections, but the exact interval can vary based on tank type and other regulations.
Step-by-step explanation:
The American Society of Mechanical Engineers (ASME) requires that pressure vessels, including ASME tanks, are periodically inspected and recertified to ensure safety and compliance with applicable codes and standards. The recertification interval for ASME tanks can vary based on the type of tank and its service conditions, but typically, hydrostatic or ultrasound test recertifications are conducted every 5 years, with visual inspections often required more frequently, such as annually.
For specific tanks, such as those used in the transportation of goods or mobile pressure vessels, local regulations or federal guidelines like those from the Department of Transportation (DOT) may dictate the recertification interval, which may be different from stationary ASME tanks.
It is important for owners and operators of ASME tanks to consult the latest ASME codes and any applicable local or federal regulations to determine the exact recertification intervals for their tanks.
