UPI manufactures robust HDPE / PP storage tanks and reservoirs that serve the storage needs of the housing, municipal and industrial sector. Individual tanks capacity range from 100 gallons to 40,000 gallons or above. Tank units can be assembled in series to form reservoirs with total capacity exceeding 2 million gallons depending on space availability. Tanks / Reservoirs can be installed above the ground or underground and are provided with required inlet, outlet pipe, manhole entry, vent pipes, and PE / PP ladder (if required).
The versatility of UPI’s HDPE / PP Tanks makes them the ideal choice for the storage of water and a diverse range of chemicals, grains, effluents and corrosive materials. The maintenance free material offers following advantages over the conventional types (e.g., Concrete, Steel, GRP):
Tanks are manufactured by using an automated process of extrusion that is specifically designed to wind extruded and hot plastic state material spirally onto a pre-heated and revolving mandrel. Overlap on the edge is fused homogeneously together while it is in the hot plastic state, producing a smooth internal surface. Once the tank body is extruded, it is allowed to cool in open space and therefore subjected to less induced stress. Following this, the tank end caps and entry manholes with stiffeners are extrusion welded on the tank body. Subsequently, tank fittings and accessories are installed onto the tank. The sizes and orientation of the fittings are customized to customers> requirement. This allows for more precise installation of the tank at site and save time and it is cost effective. The entire tank is then ready to be installed at site without the need for any major additional work to be done at site.
Tanks are manufactured as to resist the static horizontal or vertical pressure. The tank walls are produced to resist the radial and axial loads induced by its contents and / or environment. Vertical tanks considerable height (e.g., > 6m) can also be produced with varying wall thickness for optimum options and efficiency. Pressure capacity and stiffness are based inputs from design consultant / client. For horizontal tanks in underground applications, stiffness / buckling guidelines should be compliance with BSEN 1295 or to another applicable international standard. Factors such as Factors s installation depth, traffic and area load, ground water table, soil characteristics and other installation conditions should be analyzed. Anti-floatation blocks should be provided if deemed necessary.
