Emergency FRP Lining Repair for 15,000L MS HCL Tank at Delta Agro Food

Project Overview

Delta Agro Food faced a critical industrial failure when a 15,000-liter Mild Steel (MS) storage tank containing 34% Hydrochloric Acid (HCL) developed internal corrosion failure, resulting in severe leakage and chemical loss of approximately 10 tons of HCL.

The incident caused urgent production disruption and environmental safety risk, requiring immediate industrial repair and corrosion protection solution.

FiberXperts Enterprise was assigned to execute an emergency FRP (Fiberglass Reinforced Plastic) inner lining system to restore tank integrity and prevent further chemical damage.

Problem Summary

The MS tank suffered from:

  • Internal corrosion due to 34% HCL exposure
  • Sudden leakage from weakened steel surface
  • Loss of approximately 10 tons of HCL chemical
  • Production downtime and operational disruption
  • High safety and environmental risk

Immediate chemical-resistant rehabilitation was required.

Emergency Solution Provided

FiberXperts Enterprise performed a rapid FRP inner lining repair system to seal the damaged MS surface and restore chemical resistance.

Work Scope:

  • Emergency shutdown and tank internal inspection
  • Mechanical grinding surface preparation to remove corrosion
  • Cleaning and defect removal of damaged MS surface
  • Application of chemical-resistant FRP laminate system
  • Multi-layer buildup to achieve 6mm protective thickness
  • Controlled curing and quality inspection

Technical Specifications

  • Tank Capacity: 15,000 Liters
  • Tank Material: Mild Steel (MS)
  • Chemical Stored: Hydrochloric Acid (HCL)
  • Concentration: 34%
  • Failure Type: Internal corrosion & leakage
  • Chemical Loss: Approx. 10 tons of HCL
  • Surface Preparation: Grinding method
  • Lining Material: FRP (Fiberglass Reinforced Plastic)
  • Thickness Applied: 6mm
  • Application Method: Manual lamination system

Project Timeline

  • Total Repair Time: 3 Days
  • Type of Work: Emergency shutdown repair
  • Downtime: Minimized as much as possible

Results & Recovery

  • Complete sealing of leakage points
  • Restoration of chemical containment system
  • Full resistance against 34% HCL corrosion
  • Prevention of further chemical loss
  • Extended service life of MS tank
  • Safe restart of production operations

Key Impact

This emergency FRP lining repair successfully prevented further chemical waste and financial loss while restoring safe industrial operation. The project highlights the importance of FRP lining systems for chemical storage tanks exposed to highly corrosive acids.

Conclusion

The emergency rehabilitation of a 15,000L MS HCL tank (34%) at Delta Agro Food, which suffered leakage and 10 tons of chemical loss, demonstrates FiberXperts Enterprise's capability in delivering fast-response industrial FRP lining solutions. The 6mm FRP system restored full chemical resistance and ensured long-term operational safety within just 3 days.
