Glass fiber reinforced plastic container series products are corrosion-resistant, anti-aging, light weight, high strength, smooth inner surface and excellent anti-seepage performance. It is easy to form, easy to maintain, and has a long service life. Strong designability (the corrosion resistance, heat resistance, antistatic resistance, flame retardant and other properties of glass fiber reinforced plastic equipment can be improved by selecting different matrix resins, and the elastic modulus and strength in different directions can be achieved by different fiber layering layers and layering angles). Saddle bearings are mostly used for horizontal tanks (composed of backing plate, web plate, rib plate and bottom plate, with an angle of ≥120°).
