FRP Chemical Tanks
FRP (Fiberglass Reinforced Plastic) chemical tanks are engineered storage containers manufactured using high-quality thermosetting resins reinforced with fiberglass. These tanks are designed to safely store and process a wide variety of aggressive chemicals, acids, alkalis, and corrosive substances in industrial and commercial settings. With exceptional resistance to corrosion, long service life, and customizable design features, FRP chemical tanks have become the preferred choice across chemical processing, water treatment, food and beverage, mining, and power industries.

FAQ
Q :
How do I choose the right resin for my chemical storage?
UN :
The correct resin depends on: Chemical type Concentration Operating temperature Duration of exposure For strong acids or oxidizing agents, vinyl ester resins are recommended. For general-purpose storage, isophthalic polyester may be sufficient.
Q :
What sizes are available for FRP chemical tanks?
UN :
We offer a wide range from 500 liters to over 300,000 liters. Tanks can be vertical, horizontal, underground, or rectangular based on your needs. Custom sizes and designs are also available.
Q :
Are FRP tanks safe for outdoor use?
UN :
Yes. FRP tanks are UV-resistant and weatherproof. An additional UV-protective gel coat or outer resin layer is often applied for long-term durability in outdoor environments.
Q :
Can FRP tanks handle high temperatures?
UN :
Yes, depending on the resin system: Vinyl ester tanks: up to 120°C Isophthalic polyester: up to 65°C Always confirm with the supplier based on your specific chemical and conditions.
Q :
Are FRP tanks pressure-rated?
UN :
Standard FRP chemical tanks are atmospheric pressure vessels. However, custom tanks can be engineered for low-pressure or vacuum applications, such as scrubbers or reactors.
