Be restricted by the transportability, the tank which its diameter is more than DN4000mm has been become the difficult point between the ordering party and the contracting party. To meet the requirements of the order party, our company developed this set of large scale site winding, this set is combined structure, can be assembling or dismountable, the set can be transported to the client site. The set is to be assembled beside the foundation of the large tank according to the requirements of the client. Then the large tank can be finished.

Ⅱ. VFW-25000 Computer Control Vertical Site Winding Machine

1. General
VFW-25000 computer control vertical site winding machine is the most advanced winding machine (hereinafter called Winding Machine) with super large diameter developed by our company, absorbing the foreign advanced technique. It is controlled by computer, specially used for site winding of large caliber FRP tanks. This machine can produce FRP tanks with the diameter from 4m to 25m with the suitable mandrel. The control center of this machine is industrial computer made in Taiwan. Once input the parameters of winding product, the computer can finish the design of linearity of the tank automatically, and then control the compound movement of mandrel rotation and the shift of trolley, put the fiberglass immersed by resin on the inner liner fully in order. This winding machine is the combination of technique and science, such as mandrel rotation, shift of the trolley, and layout of winding roving are all precisely controlled by computer software. The FRP products wound by this machine are widely used in chemical industry, petroleum, and brewery and so on.

2. Parameters of the Winding Machine
Winding diameter scope: 4m-25m
Max height for each section: 6m (Note: if it is more than 6m, it can be formed by many sections )
Winding angle: 60°-90°
Max rotating speed of the mandrel: 4.6rpm
Woven roving strands: 70*
Productivity: 500Kg/h*
*Note：The productivity and the quantity of strand is based upon the quality of roving
