INTERNAL PARTITION We are one of the leading supplier and Installation Company of GRP / SMC Molding Sectional Panel water MOLDING SECTIONAL PANNEL WATER TANKS WITH COMPARTMENTS. We are applying this facility by constructing partitions inside the water tanks.

TANK- INTERNAL PARTITION SYSTEM:
The partition wall is made up of GRP/SMC hot pressed panels. The wall is made with panels of varying size mainly are, 1.00Meter x 1.00Meter, 1.00 Meter x ½ meter & ½ Meter x ½ Meter. The weight configuration of panels for the partition wall is same as using for the side wall (so that the partition wall also can withstand the designed hydrostatic pressure). All panels in the partition wall are assembled together with high quality gasket and SS316 Bolts & Nuts. The wall is supported internally with stainless steel supports (double rod system) and the whole tank is supported externally with G I columns and Tie Rods.

Installation space:
about 600mm space in all direction is required as shown at the bottom image for maintenance and installation of tanks. When want to install multiple tanks with different purposes in the confined space of your underground boiler room you keep the installation guideline in mind beforehand which is a required space of 1 meter. The space in the centre is secured for maintenance. So you should install two water tanks with 6-ton capacity each. If you install partition-type water tanks as shown in the picture you can use 16 tons of water with a single water tank - 8 tons for drinking and 8 tons for other purposes. This will reduce your installation cost and also bring easy maintenance.

THE BASIS OF PANEL DESIGN
The panels are designed using the latest Finite Element Methods of Analysis. Computer modeling allows subtle changes to be made in thickness and geometry of panels, such that stresses and deflections are minimized for high factor of safety and good performance of tanks. For instance: Roof and floor panels of the tanks take compressive loads to make them self-sealing and self-draining. Side panels have their central shell portion designed to take tensile loads. In both cases the load is transferred to the flanges.

HEAT INSULATTED PANELS
With GRP materials excellent for heat insulation, urethane with 25mm thickness foamed in for heating and the warming cover attached appropriately for the external condition. The internal temperature of water tanks never change even in extreme or tropical environments. For its excellent heating and insulation properties, there is no freezing or dew formation. Assembly is straightforward, with special skilled personals. Panels shall be factory insulated on the top and sides, using the 25mm thick low-density polyurethane system. Panels to be insulated within a profiled face covering the maximum surface area and to be encapsulated with an external weather skin made from ultraviolet stabilized material providing total protection against weathering. Connections to be fitted on flat insulated panels and all holes shall be sealed with recessed plastic section from the outer surface of the insulation skin to the cistern panel.

CORE MATERIALS MAY INCLUDE

  • Styrofoam
  • Polyurethane Foam
  • A Combination of Styrofoam & Polyurethane Foam
  • Phenolic Foam

HEAT PROTECTION PERFORMANCE
Due to the wide range of core materials available, products can be made to suit individual customer’s needs. The thickness of core materials measures the rate at which heat is lost through the material. Upon the middle-east countries climatic condition, we are manufacturing 25mm standard thick of the core materials. The ‘U’ value measures the rate at which heat is lost through a material. The lower the ‘U’ value, the lower the amount of heat lost and the lower the amount of energy wasted. ‘U’ values will invariably depend on the core material chosen, but our panels can be manufactured to suit specifications, which requires a ‘U’ value lower than or equal to 0.35 W/m2K.
