FRP Pickling Tanks

FRP chemical process equipment includes reactors, scrubbers, columns, and other vessels where chemical reactions or processing take place. These units are fabricated with seamless fiberglass construction and corrosion-resistant liners (PVC, PP, PVDF, PTFE, etc.). Designed per BS/ASTM/JIS/ASME/RTP standards, they safely handle corrosive fluids and can operate at pressures up to 10 bar. With features like UV and fire-retardant additives available, this equipment is suitable for highly aggressive chemical environments.

Key Features

  • Acid-Resistant Laminate: Thick FRP laminates (often vinyl ester or phenolic resin) protect against concentrated acids.
  • Flat Bottom / Open Top: Rectangular or open-top tanks to accommodate metal parts.
  • Drainage & Ventilation: Equipped with leak-proof drains and fume vents to handle hazardous vapors.

Benefits

  • Cost Savings: Eliminates frequent replacement of steel tanks eaten away by acid.
  • Safety: FRP is non-sparking and can be designed to contain spills.

Applications

  • Steel Pickling: Removing oxides from stainless, carbon, or alloy steels.
  • Desulfurization: Process tanks in sulfuric acid regeneration plants.
  • Electroplating & Surface Finishing: Holding tanks for cleaning and etching.

Technical Specifications

  • Acid Types: Suitable for HCl, HNO₃, and H₂SO₄ (up to specified concentrations).
  • Volume: Typically ranges from 1 to 100 m³ per tank; modular configurations available.
  • Temperature: Operates from ambient temperature up to approximately 60 °C, depending on application.
  • Lining: Uses vinyl ester or PTFE lining for extreme service conditions.

Unique Selling Points

  • Experience with Aggressive Media: Proven FRP designs for prolonged immersion in strong acids.
  • Turnkey Pickling Lines: Integratable with FRP filtration, neutralization, and rinse tanks.
