Fiberglass reinforced plastic (FRP) container series are highly corrosion-resistant, aging-resistant, lightweight, and strong, with a smooth inner surface and excellent leakage prevention. Easy to form, simple to maintain, and have a long service life. They offer strong design versatility (the corrosion resistance, heat resistance, antistatic properties, flame retardancy, etc., of the FRP equipment can be improved by choosing different matrix resins; different elastic modulus and strength in various directions can be achieved through different fiber laying layers and angles). Horizontal tanks are mostly supported by saddle-type supports (consisting of pads, webs, ribs, and bottom plates, with an included angle ≥120°).
