Industrial Chemical Tanks

GPI fiberglass-reinforced plastic tanks are designed and fabricated to meet storage needs for industrial chemicals, concentrations, and temperatures. In order contain the harshest contents, our chemical tanks are made to satisfy the requirements of international standards for storing chemicals such as bleach, acid, sodium chloride, ethylene glycol, and caustic soda.

Storage Tanks can be customized to use compatible resins (Polyester, Vinyl ester, Epoxies etc.), with thermoplastic liners (PP, PP-H, PVC, CPVC, PVDF, ECTFE, FEP, and PFA). Tanks and Equipments are fabricated using contact molding and filament winding processes in compliance with international design standards BS 4994, BS EN 13121, ASME RTP-1, ASME Section-X, ASTM D (3299, 4097, 3517, 3982, 4167, 2634, 3982).

Chemical tanks are corrosion resistant, have a maintenance-free exterior, and are made to protect the environment. Whether the industrial chemical tank is storing mild or aggressive chemicals, we offer Inspection and Test Plan procedures to meet stringent industrial requirements such as:

  • Acetone sensitivity
  • Barcol hardness
  • Dimensional compliance
  • Physical properties
  • Glass content and hydrostatic
