Fiberglass Reinforced Plastic (FRP) Agitated Vessels

Fiberglass reinforced plastic (FRP) agitated vessels utilize composite construction to provide excellent corrosion resistance at low weight for atmospheric and low-pressure applications. These vessels offer economical solutions for corrosive chemical storage, water treatment, and other applications where FRP’s properties provide advantages over metallic construction.

Why Choose Fiberglass Reinforced Plastic (FRP) for Agitated Vessels?

FRP vessels provide corrosion resistance to a wide range of chemicals at lower cost and weight than metallic alternatives. Their seamless construction eliminates weld-related corrosion concerns. FRP is ideal for atmospheric tanks, scrubber vessels, and other applications where its chemical resistance and economics offer clear advantages.

Frequently Asked Questions (FAQs)

What chemicals can FRP vessels handle?

FRP chemical resistance depends on the resin system selected. Vinyl ester resins handle most acids and bleach solutions. Epoxy resins suit alkaline environments. Specialty resins address specific chemicals. Temperature and concentration affect resistance. We recommend resin systems based on complete chemical exposure analysis.

What agitation options are available for FRP vessels?

FRP vessels typically use top-entering agitators with appropriate mounting provisions reinforced into the vessel structure. Side-entering agitators require special reinforcement. Agitator materials must be compatible with process chemistry—often FRP, thermoplastic, or alloy coated. We design complete FRP agitation systems.

What are the limitations of FRP vessels?

FRP limitations include lower temperature capability than metals (typically 200°F maximum depending on resin), atmospheric or low-pressure rating, potential UV degradation without additives, and lower impact resistance. Design must address laminate loads from agitator mounting. FRP excels within its capability envelope.
