May 11,2006 self anchored flat bottom tanks closed top API Standard 650 tanks#0183;The tanks are anchored for overturning with bolt chairs,so if the tank moves the bolts will bend and I believe that that is the real concern that they have. The bolts should have some nominal amount of pretension,and that force can be added to the weight in figuring the friction- that's how the bolts resist sliding.[DOC]APPENDIX BRECOMMENDATIONS FOR DESIGN AND self anchored flat bottom tanks closed top API Standard 650 tanks#0183;Web viewSee API 650 Appendix I Under Tank Leak Detection and Subgrade Protection A release prevention barrier (RPB) such as a flexible impermeable membrane liner can be used to increase the inspection interval of the tank bottom API 653 6.4.3.The outside edge of the tank bottom should be sealed to prevent moisture from going under the tank.Venting Aboveground Tanks Part 1 - Tank Types and the API May 01,2000 self anchored flat bottom tanks closed top API Standard 650 tanks#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
