Fiberglass tanks may be designed and manufactured to fit any number of geometry, strength and corrosion requirements. There are many applications for small tanks for corrosive fluid applications. These smaller applications may be cost effectively addressed using rectangular or square tank geometry, usually not practicable with larger (>1000 liter) sizes. The tanks shown in the picture were Resin Transfer Molded (RTM) for use in battery acid handling. There were approximately 1000 tanks manufactured in two sizes. Use of RTM ensured excellent part to part uniformity and quick turnaround on parts. An added benefit is the smooth "mold side" surface for both the inside and the outside of the tank, an aid in cleaning. Typical Specifications: RTM Tanks shall be designed for the loads imposed with maximum deflection of ½% of span. Design is to be supported by engineering calculations by staff mechanical engineer experienced in fiberglass structural design. Materials of construction are to be suitable to meet the corrosion requirements. Resin Polyester or Vinyl Ester Resin as required by corrosion resistance Nominal Thickness 0.25" minimum with local reinforcement as required Flex Strength 31,800 psi (ASTM D-790) Flex Modulus 1,270,000 psi (ASTM D-790) Tensile Strength 20,000 psi (ASTM D-638) Tensile Modulus 1,430,000 psi (ASTM D-638) Design & Construction: All one piece molded construction using a closed mold system resulting in a smooth surface on both the interior and exterior of the tanks. Corrosion resistant – Suitable for the application at the design temperature All cut edges to be resin sealed.
