These tanks can be distinguished from a cone roof tank by the presence of a wind girder that rings the top of the tank.The wind girder acts as a stiffening ring for the top of the tank,giving it additional structural support.Between the shell of the tank and the roof edge,a rim seal will be provided to prevent vapors from escaping to the Location of Primary Wind Girder - Storage tank engineering Wind girders are usually formed by welding an angle or a channel around the top edge of the shell.At the top of an open tank (or one with a floating roof),circumferential stiffening is needed to maintain the roundness of the tank when it is subject to wind load.This stiffening is particularly necessary when the tankIntermediate Wind GirderMay 05,2010 SUG I tanks wind girders#0183;Considering clause 5.9.1 of standard API 65011th Edition,2008,one of my coworkers believe that fixed roof storage tanks must be designed without any Intermediate wind girder.while I believe using Intermediate wind girder is an independent category and it can be applied for both open-top and fixed-roof storage tanks based on clause 5.9.7.
