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.Venting Aboveground Tanks Part 1 - Tank Types and theMay 01,2000 self anchored tanks bottom joints#0183;NOTE Vertical cone-roof tanks built to UL or API specifications may have a weak roof-to-shell seam,if the seam is built with weak angle iron and the roof does not slope more than two inches per foot.The roof is attached to the top angle iron,with only a three-eighths-inch weld on top of the angle.On the bottom-to-shell seam,both sides of the joint are secured by a three-fourths-inch or Used Tanks For Sale,Used Stainless Steel Vessels SPITank 250 gallon vertical tank,Stainless Steel,25 psi @ 350 self anchored tanks bottom joints#176; F internal,125 psi @ 350 self anchored tanks bottom joints#176; F half jacket,.75 hp agitator,conical bottom
