Vertical FRP Tank

Vertical FRP tank, or vertical FRP vessel, is made of a kind of nonmetallic material which has strong anti-erosion ability, high strength and long operating life. Vertical FRP tank which is generally cylindrical is set on the base directly and its head is flat or round.
The walls of a vertical FRP tank are comprised of three layers:
Lining. The thickness of the inner layer is 2.5 - 3 mm. This layer which performs as an inside support and airtight partition, adopts anti-corrosion resin with good toughness, high elongation and low curing shrinkage rate.
Reinforced layer. It is also called support layer. Reinforced layer is made using filament winding process. The thickness of this layer depends on the diameter, pressure, safety factor and other factors.
Surface layer. Its thickness is about 0.5 mm. Surface layer is highly anti-aging, uvioresistant and it does well in preventing the permeation of foreign matter. Its resin content is more than 80%.
