FRP & Thermoplastic Lined FRP Pressure Vessels

About FRP & Thermoplastic Lined FRP Pressure Vessels

FRP (Fiberglass Reinforced Plastic) pressure vesselsare high-performance composite containers designed to safely store and handle pressurized fluids and gases, especially in corrosive and chemically aggressive environments. Constructed by reinforcing thermosetting resins (such as epoxy, vinyl ester, or polyester) with glass fibers, these vessels offer an excellent combination of corrosion resistance, high strength, and low weight.

In more demanding applications involving highly reactive or corrosive chemicals,thermoplastic-lined FRP pressure vesselsare used. These vessels feature an internal lining made from corrosion-resistant thermoplastics such as PP (Polypropylene), PVC (Polyvinyl Chloride), PVDF (Polyvinylidene Fluoride), or PTFE (Polytetrafluoroethylene), bonded to the structural FRP shell. This dual-laminate construction ensures maximum chemical compatibility on the wetted surfaces while maintaining the structural integrity provided by the FRP exterior.

FRP and thermoplastic-lined FRP pressure vessels are commonly used in chemical processing, water treatment, food and beverage, pulp and paper, and power generation industries. They provide a cost-effective, long-lasting alternative to metallic vessels, especially in applications where corrosion is a major concern.
