Various storage tanks, FRP performance can be planned, designed according to different uses effectively the expertise of a variety of materials, to do reasonably timber service users. FRP tank: light weight: FRP density of about 1.5-1.9g/cm3, steel 1/4 level, compared with about 1/3 of the light metal aluminum, while the static mechanical strength close to or more than ordinary carbon steel . Corrosion. 3 small thermal expansion coefficient, good thermal insulation properties. Molding easy, easy maintenance medium morphology:. Liquid tank gas tank the solid tank by the use of pressure points 1. Commonly used tank pressure tank, tank shape. Circular horizontal tank round vertical tank 3. rectangular tank
