FRP Chemical Storage Tank Manufacturer in India

The isophthalic-resin FRP suits a wide range of industrial chemicals; share your media and we will confirm compatibility.

10,000 to 55,000 litres per tank, 2400 mm diameter, customizable length.

Both. The UV-resistant build supports above-ground and underground installation.

Every tank passes pneumatic leak, dimensional accuracy and laminate strength testing before dispatch.

FRP (Fibre Reinforced Plastic) is corrosion-proof, non-conductive and naturally leak-proof, so unlike RCC it will not crack, leach or seep, and unlike mild or galvanised steel it will not rust when in constant contact with sewage or water. It is far lighter than concrete yet strong enough to withstand soil and hydrostatic pressure when buried, and it can be moulded as a single sealed vessel rather than assembled on site. Compared with HDPE, filament-wound FRP offers higher structural stiffness for large underground and pressure-bearing tanks, and a well-built unit typically lasts 25 years or more.

Filament winding is a manufacturing process in which continuous glass fibre, soaked in resin, is wound under controlled tension over a rotating mandrel at precise angles, then cured to form the tank wall. CNC control of the winding angle and layer thickness produces a dense, uniform, void-free laminate with consistent strength in every direction. This gives the finished vessel high hoop and axial strength, excellent leak resistance and predictable wall thickness, which is why it suits underground and pressure-bearing FRP tanks.

An underground FRP unit is lowered onto a compacted, level bed and then surrounded with backfill that supports the wall evenly against soil pressure. Clean granular material such as sand or fine aggregate is generally preferred because it is easy to place and compact in layers, though a concrete surround can be specified for high water-table or heavy-load locations. Filling the tank with water as backfill rises helps balance the pressure, and the cover should be rated for any traffic passing over it.

Yes. FRP vessels are moulded or filament-wound as a continuous, seamless laminate with sealed joints, so there are no porous surfaces or construction seams for liquid to escape through, and the material does not crack or corrode over time the way concrete and steel can. This prevents sewage or stored water from seeping out and protects the surrounding soil and groundwater from contamination. Proper installation and gasketed pipe connections maintain this leak-proof integrity in service.

FRP is highly resistant to corrosion, UV, chemicals and weather, so a properly manufactured and installed unit is designed for a long service life, commonly in the range of 25 years and beyond for tanks. The mechanical parts such as blowers and pumps wear over time and are periodically serviced or replaced, but the FRP structure itself does not rust or rot. Sound installation and routine maintenance are the keys to reaching the full design life.
