An FRP Vertical Storage Tank is a type of storage container made from Fiberglass Reinforced Plastic (also known as Glass Reinforced Plastic or GRP), designed in a tall cylindrical shape for optimal use of ground space.

They are widely used across various industries, particularly for storing corrosive chemicals, water, and wastewater, due to their superior material properties compared to traditional steel or concrete tanks.

 

🛠️ Material and Construction

 

FRP is a composite material consisting of two main parts:

• Fibers (Reinforcement): Typically fiberglass (glass fibers) provides the exceptional strength and high tensile properties.

• Polymer (Matrix): A thermosetting resin (e.g., polyester, vinylester, or epoxy) acts as a binding agent that protects the fibers and provides the chemical resistance. The type of resin is selected based on the specific chemical it will store.

The tank wall is often constructed in multiple layers, including:

1. Inner Corrosion Liner: A resin-rich layer using a corrosion-resistant resin (like Vinylester) and often reinforced with C-Glass veil. This layer is the primary defense against the stored medium.

2. Structural Layer: Composed of layers of fiberglass reinforcement (like chopped strand mat and filament windings) to provide the mechanical strength to withstand hydrostatic pressure, wind, and seismic loads.

3. Outer Surface Layer: A protective layer that is UV-resistant and weather-proof.

Heat Exchanger & Reactor Vessel

Heat Exchanger and Reactor Vessel are two essential process equipment widely used in chemical, pharmaceutical, petrochemical, food processing, and other industries for efficient heat transfer and controlled chemical reactions.

1. Heat Exchanger

A Heat Exchanger is a device designed to transfer heat between two or more fluids without mixing them directly.

Types:

• Shell & Tube Heat Exchanger – Ideal for high-pressure, high-temperature applications.

• Plate Heat Exchanger – Compact design, high efficiency, easy to maintain.

• Finned Tube Heat Exchanger – Enhanced heat transfer for air-cooled or gas applications.

• Double Pipe Heat Exchanger – Simple construction for small-scale processes.

Applications:

• Cooling or heating process fluids.

• Condensation or evaporation in distillation processes.

• Waste heat recovery.

• HVAC and refrigeration systems.
