Hot Press GRP Sectional Panel Tanks in UAE

It is a water tank assembled on site from standardised GRP (glass fibre reinforced plastic) panels that are moulded under high temperature and pressure. The panels are bolted together with a sealing tape in every joint and braced with stainless steel and hot dip galvanized steel parts. Because the tank arrives as panels rather than one shell, it can be built in confined spaces.

Wall panels come in 1000 x 2000, 500 x 2000, 1000 x 1500, 500 x 1500, 1000 x 1000, 300 x 1000, 500 x 1000 and 500 x 500 mm. Bottom panels are 1000 x 1000, 500 x 1000 and 500 x 500 mm. Roof panels are 1000 x 2000, 1000 x 1000, 500 x 1000 and 500 x 500 mm. Drain and manhole panels are 1000 x 1000 mm. Panel shapes can change without notice.

The panel system allows side wall compositions from 1 m up to 5 m high, in steps of 0.5 m, built by stacking the standard panels.

Yes. Panels are available insulated or non insulated. An insulated panel has a 3 layer structure with a rigid polyurethane foam core of 25 to 40 mm between GRP skins. Its thermal conductivity is 0.02 Kcal/m.hr.C, compared with 0.15 for standard GRP and 37.0 for steel.

Each joint is sealed with a special PVC or EPDM sealing tape that is compressed between the panel flanges by the assembly bolts. Bolt caps are added to the external bolts to prevent white peril or rust.

Internal reinforcement and roof bolts are stainless steel (SUS 304 or SUS 316). External brackets, bars, corner frames, ladders and the base frame are SS41 steel, hot dip galvanized. Bolt sizes are M10, M12 and M14.

It depends on the system and the water height. With the external reinforcement system, there are no internal reinforcement parts up to 3 m water height, which avoids rusting. Above 3.5 m water height the internal parts are optimised to keep maintenance and cleaning easy.

The design standards cover hydrostatic pressure (water height in metres x 0.1 kgf/cm2), horizontal seismic load Kh = 2/3 and vertical Kv = 1/3, wind, and snow load. Water temperature is suitable up to 50 C and dusty environments up to 70 mg/m3. Confirm the design loads for your site with KHAZAAN before ordering.

It is one tank divided by a partition panel into two sections. One section can hold drinking water and the other service water, such as for fire fighting. A typical example is a 16 ton partition tank used as 8 tons of each. Two separate tanks in the same room would be limited to about 6 tons each, because 1 m must be kept between tanks for maintenance.

The tank sits on concrete plinths 300 to 400 mm wide and over 600 mm high including the base frame, spaced less than 1 m apart. The plinth layout is the tank width and length plus 400 mm and must be level to within 1/500. The base concrete must be at least 180 kg/cm2 and the mortar layer no more than 20 mm thick.

At least 600 mm from the walls and 1,000 mm below the ceiling of the tank room, so the tank can be inspected, maintained and repaired.

Regular inspection more than twice a year is recommended, because the tank stores water for consumption. If the tank will be unused for a long time, drain it. See our guide to water tank cleaning and maintenance for the cleaning schedule.

The panel material test data on this page shows nil toxicity, nil micro biological growth and 0% light transmission. For potable use in the UAE, confirm the approvals that apply to your project with KHAZAAN before ordering.

Panel tank prices depend on the capacity, panel and reinforcement specification, insulation, and site conditions, so they are quoted per project. Send your capacity or available dimensions on WhatsApp for a quotation.
