Vertical FRP tank with a small diameter


Vertical FRP tanks, also known as vertical FRP vessels or FRP vertical tanks, are a kind of vertical nonmetallic container with a circular end cap and a flat end cap. Featured by excellent corrosion resistance, high strength, lightweight and long service life, FRP vertical tanks are widely used for storing sulfuric acid, hydrochloric acid, gasoline, asphalt and other corrosive media.

In addition, FRP vertical tanks can be designed flexibly to meet the specific need of different industries including chemical, environmental protection, food, pharmaceutical industries, etc.

FRP vertical tanks occupy a small footprint area and commonly work in clusters to achieve amazing storage capacity in limited space.

  • Lightweight yet high strength
    The relative density of FRP tanks ranges from 1.5 to 2.0, only 1/4 to 1/5 to that of carbon steel. However, its tensile strength is close to or even higher than that of carbon steel, and its specific strength can be compared to advanced alloy steel.
  • Excellent corrosion resistance
    FRP is an excellent corrosion-resistant material with great resistance to atmosphere, water and general concentrations of acids, bases, salts and various oils and solvents. It has been widely used in various field of chemical industries for corrosion resistance and are gradually replacing carbon steel, stainless steel, wood, nonferrous metals, etc.
  • Good dielectric properties
    It maintains good dielectric properties at high frequencies. It does not reflect radio waves and is not subject to electromagnetic action, delivering good microwave transmission performance.
  • Good thermal properties
    It has a low thermal conductivity and 1.25–1.67 kJ/(m·h·K) at room temperature, only 1/100 to 1/1000 of metals. It is an excellent thermal insulation material.
  • Flexible design
    • Various structural products can be designed flexibly as required to meet your specific usage requirements.
    • A variety of fiber and resin materials are available to suit to different working environments. For example, corrosion-resistant, instantaneous high-temperature resistant, high strength and insulation vertical FRP tanks can be designed.
  • Superior winding process
    Superior winding process makes one-step forming possible, bringing great economic effects. Its process superiority is highlighted in circumstances where a few quantity of vertical FRP tanks with complex shapes are required and one-step forming is hard to achievable.
  1. Barrier: Protect the safety of workers.
  2. Cover: Hand lay-up
  3. Shell: Microcomputer controlled filament winding process
  4. Ladder: Facilitate workers to carry out their work.
  5. Bottom: Hand lay-up
  6. Flange hole: Store or discharge gases or fluids.
  7. Manhole: Facilitate workers to check and observe conditions inside the tank.
