Storage tanks,Fixed-roof tanks,Floating roof tanks

A typical fixed-roof tank consists of a cylindrical steel shell with a cone- or dome-shaped roof that is permanently affixed to the tank shell.Storage tanks are usually fully welded and designed for both liquid and vapor tight,while older tanks are often have a riveted or bolted construction and are not vapor tight.Steel Water Storage Tankson the Steel Tank Institute/Steel Plate Fabricators Associations Subcom- 1-14 Self-supporting dome roof or umbrella roof..14 1-15 Self-supporting ellipsoidal roof 2-4 Recessed inletoutlet pipe bottom connection detail 51 2-5 Nonrecessed inletoutlet bottom connection Stainless Steel - GRAHA EXCELAvailable in 2 type; flat bottom or circular bottom with steel structure.Dual Finishing Design Combination of Matte Satin Finishing on top and bottom of tank with Supreme Shine Polishing on the body to create better color pattern,minimize finger print mark,dirt and scratch on tank.
