Types of Steel Storage Tanks

Flat Bottom Reservoir Tanks.Reservoir tanks come in a broad range of sizes,with the diameter exceeding the height.Reservoirs are economical and effective storage,especially on higher ground.Since these tanks have a lower profile,it is easy to mask them with foliage.Technical Inquiries for API Standard 650,Welded TanksIs it permissible to use Group I plates for a tank bottom,except for plates welded to the shell,for tanks with a -50 ground supported flat bottom tanks Spacing of Connections and Welds#176;F design metal temperature?
