Efficient Horizontal FRP Tank Winding Machine

Horizontal FRP tank winding machine is designed to manufacture horizontal FRP tanks, vessels and other winding molded products. These products manufactured from quality FRP materials feature excellent acid and alkali resistance and ensure there is no toxin release and smell. So they are ideal for containing corrosion liquids such as acid, alkali, salt in the chemical industry.

Normally, three types of winding machines are available. The winding machine HTW-1 and HTW-2 for manufacturing tanks below DN4000mm are generally used in the workshop. However, HTW-3 is recommended to be used on site for manufacturing tanks and vessels in larger sizes. Meanwhile, HTW-3 filament winding machines efficiently reduce the manufacturing cost and solve the transportation problems.

A horizontal FRP tank winding machine is winding a FRP tank with diameter less than 4000mm in the workshop.

FRP tanks manufactured by our advanced equipment have three layers: anti-corrosive inner layer, reinforced structural layer and outer anti-aging layer as shown below. So FRP tanks are manufactured through three steps.

Three layers of horizontal FRP tanks
The structure of horizontal FRP tanks
  • Anti-corrosive liner layer: The liner layer of FRP tanks refers to impermeable anti-corrosive layers sprayed using airbrush. It is composed of two films of polyester containing anti-corrosive resin in thickness of 3mm with 80% resin content.
  • Reinforced structural layer: with resin content of 45% to 50%.
  • Outer anti-aging layer: about 0.2mm - 0.5mm in thickness with about 95% resin content.

Step 1: Anti-corrosive liner layer spraying.
