Tanks and Silos

Product catalog summary

Overview: The document describes the discontinuous filament winding plants used for manufacturing tanks and silos. This equipment is suitable for creating both vertical and horizontal tanks for various applications, including above and below ground installations.

Manufacturing Process: The filament winding process involves using a fixed length, rotating mandrel. Raw materials are distributed by a horizontally moving carriage. The tank's cylindrical part is cured after achieving the required body thickness and then removed from the mandrel. The properties of the tank depend on the raw material ratio and the winding angle of the fiberglass, which ranges from 35° to 90°.

Applications: Tanks and silos manufactured using this process can store both solid and liquid foodstuffs and chemicals.

Design Variables: The tanks and silos can have diameters ranging from ND 1000 to 12000 mm and lengths up to 12 meters. They can be designed with single or double walls, atmospheric pressure ratings, and stiffness ranging from 1250 to 10,000 N/m². End caps can be domed, flat, or conical.

Plant Characteristics: The plants are CNC controlled with 2, 3, or 4 axes and can support cantilever or double stock mandrels. They offer hoop, chop, and helical winding, as well as polar winding with a minimum of 3 axes. Additional features include a sand supply system and a rib production system.

VEM Scope of Supply: VEM provides liner stations, single or double channel helical and hoop winding stations, end caps molds, spray-up stations, curing stations, post-curing ovens, hydraulic stripping, and de-moulding stations. They also offer know-how transfer, installation, commissioning, training, and after-sales service.

DISCONTINUOUS FILAMENT WINDING PLANTS FOR TANKS AND SILOS This traditional type of the filament winding equipment allows the manufacture of vertical and horizontal tanks (above and below ground applications) and silos. The winding of the filaments is performed on a fixed length, rotating mandrel. The raw materials are distributed by a carriage moving horizontally alongside the mandrel. After the construction of the required body thickness the cylindrical part of the tank is subject to curing and then removed from the mandrel. The tank properties depend on the raw material ratio, which can include...
