Dished end manufacturing for beginners

A particular kind of dished end is widely used by the manufacturers of truck tanks the polycentric dished end.These dished ends,often made of aluminum or stainless steel,are normally made with thin plates up to a maximum of 6 mm.This thickness allows the forming of polycentric dished ends using a technique called hydroforming.Design of Steel Tanks - The ConstructorFeb 05,2010 self anchored flat bottom steel tanks cutting Plates#0183;A rectangular steel tank is shown in Fig.The rectangular steel tanks are made of steel plates with flat bottom.The widths of steel plates generally adopted are 1.20 m,1.25 m and 1.30 m depending upon availability of the plates.the thickness of steel plates should not be less than 6 mm.DESIGN RECOMMENDATION FOR STORAGE TANKS ANDthe uplift of the rim of bottom plate exists.This recommendation shows how to evaluate the energy absorption value given by plasticity of the uplifted bottom plate for unanchored tanks,as well as the Ds value of an anchored cylindrical steel-wall tank.As the number of smaller under-ground tanks used for the storage of water and fuel is
