API Std 620

Design and Construction of Large, Welded, Low-Pressure Storage Tanks, Twelfth Edition

Published by: American Petroleum Institute / 10/01/2013 / 277 pages / 12th Edition
The API Downstream Segment has prepared this
standard to cover large, field-assembled storage tanks
of the type described in 1.2 that contain petroleum
intermediates (gases or vapors) and finished products,
as well as other liquid products commonly handled and
stored by the various branches of the industry.

The rules presented in this standard cannot cover all
details of design and construction because of the
variety of tank sizes and shapes that may be

design are not given, the intent is for the
Manufacturer–subject to the approval of the
Purchaser’s authorized representative–to provide
design and construction details that are as safe as
those which would otherwise be provided by this
