self anchored storage tanks identification of welded joints

frangible roof tank as per api 650 - API (American

The intent of frangible roof design is for the roof-to-shell joint to fail preferentially to the shell-to-bottom.This you may have already known.However,in order to achieve this,it is necessary to limit the roof-to-shell strength.So,item 5 was added to accomplish this.You are correct that these items are based on an self anchored tank.[DOC]API 650.506 self anchored storage tanks identification of welded joints#0183;Web view3.The bottom is butt welded.4.The slope of the roof at the top angle attachment does not exceed self anchored storage tanks identification of welded joints#190;:12.c.Alternately,for self-anchored tanks less than 15 m (50 ft) diameter,the tank shall meet all of the following 1.The tank shall meet the requirements of 3.10.2.6 a.2.Tank design - wordFeb 04,2016 self anchored storage tanks identification of welded joints#0183;The specifications consist of engineering standards and a storage tank design specification sheet.4.3.1 Standards and Specifications API-650 covers the material selection,design,fabrication,erection,and testing requirements for vertical,cylindrical,above ground,closed- and open-top,welded steel storage tanks for internal pressures that
