An FRP (Fiber Reinforced Plastic) vessel is a container or tank made from a composite material consisting of fiberglass fibers reinforced with a plastic resin such as polyester, vinyl ester, or epoxy. These vessels are widely used in industries because they are lightweight, strong, and highly resistant to corrosion and chemicals. The fiberglass provides mechanical strength while the resin binds the fibers together and protects the vessel from chemical attack. FRP vessels are commonly used in water treatment plants, chemical processing industries, and filtration systems such as RO plants to store liquids, chemicals, or filter media. Due to their durability, low maintenance requirements, and long service life, FRP vessels are often preferred over traditional metal vessels.
