With perfect characteristic of designability, shape performance and easy to maintenance, compare with steel, FRP (fiberglass reinforced plastic) has a very high corrosion resistance, and has a specific gravity of 1.5 to 1.9, far lower than 7.8 of steel, but it’s mechanical strength is higher than steel’s, and it also has the advantage of low coefficient of thermal expansion and preface thermal insulation, FRP vessels are widely used in many fields. 

      According to the shape of media, FRP vessels can be divided into three categories of liquid, gas, solid tank; according to the pressure grade, can be divided into two categories of ATM tank and pressure tank; According to shape of vessel, can be divided into three categories of horizontal cylinder tank, vertical cylinder tank, rectangle tank; And PVC/FRP, PP/FRP, PVDF/FRP composite tanks.
