What does API 650 cover?

What does API 650 cover?

• A. Welded steel tanks for oil storage
• B. Piping design standards
• C. Structural steel shapes
• D. Vessel insulation standards

Answer: (A)

API 650 governs welded steel tanks used to store oil and other liquids above ground. It outlines how these tanks should be designed and fabricated, including material selection, shell and bottom details, welding procedures, coatings and corrosion protection, fabrication tolerances, and the testing and inspection required to ensure safe, reliable storage. It also covers repair and alteration procedures and the overall quality control expected during construction and service. This standard does not address piping design standards, general structural steel shapes, or vessel insulation standards, which are covered by other codes and standards.
