US6085472A - Method of protecting liquid storage tanks

A method of protecting liquid storage tanks from earthquakes and an anchor especially adapted to carry out this method are described.The method includes providing an energy dissipating anchor between the liquid tank and structure which will move with the ground.The anchor includes a stainless steel shaft which is secured to a ring foundation.US5137771A - Perfluoroelastomer seal - Google PatentsUS5137771A US07/422,504 US42250489A US5137771A US 5137771 A US5137771 A US 5137771A US 42250489 A US42250489 A US 42250489A US 5137771 A US5137771 A US 5137771A Authority US United States Prior art keywords ring seal flange perfluoroelastomer retaining plate Prior art date 1989-10-17 Legal status (The legal status is an assumption and is not a legal conclusion.Tank design - wordFeb 04,2016 mechanically anchored tanks annular plate#0183;For our tank Min Thickness of bottom plates = 6 + 1.5(C.A) = 7.5 mm Nominal thickness = 8 mm NOTE he ordered 10 mm thickness 4.5.2.2 ANNULAR BOTTOM PLATES Annular rings are usually used on larger tanks.An Annular Ring is a thicker plate

Preuplift Method to Anchor Liquid Storage Tanks

In many cases neither the bottom plate nor the cylindrical shell are fixed to the ground.When such an unanchored tank is subjected to seismic ground shaking,the lateral inertia of the contained liquid contributes to the overturning moment,but its weight cannot contribute to the stabilizing moment until some uplift of the bottom plate occurs.Performance-Based Seismic Design of Tanks with Energy 3.5 for self anchored tanks .4.0 for mechanically anchored tanks .In traditional seismic design,the reduction factors R ,R ,and R are not explicitly computed for the specific tank.A judgm\nt-based lump-sum reduction factor of R = 3.5 or 4 is used to account for all possible sources of load reduction.Images of Mechanically Anchored Tanks Annular Plate images[DOC]American Petroleum Institute mechanically anchored tanks annular plate#0183;Web viewFor tanks in SUG III and located where S DS =0.5g or greater,butt-welded annular plates shall be required.Annular plates exceeding 10 mm (3/8 inch) thickness shall be butt-welded.The weld of the shell to the bottom annular plate shall be checked for the design uplift load.
