The FRP pickling tank is fabricated from a composite of high-performance vinyl ester resin and alkali-free glass fiber. Specifically engineered for harsh corrosive environments involving strong acids, strong alkalis and other aggressive media, this product integrates outstanding corrosion resistance, robust structural strength and long service life, providing reliable guarantees for pickling processes in modern industry.


1. Excellent Corrosion Resistance
- Broad Medium Compatibility: Resistant to various highly corrosive media such as hydrochloric acid (concentration ≤ 30%), sulfuric acid (concentration ≤ 50%), nitric acid (concentration ≤ 20%), and hydrofluoric acid (concentration ≤ 10%).
- Stable Operating Range: Maintains long-term stability in corrosive environments with a pH value of 1–14, and has an operating temperature range of -30℃ to 80℃.
- Superior Surface Protection: The inner surface is treated with a resin-rich layer, featuring a smooth and dense finish (Barcol hardness ≥ 40), which effectively prevents medium penetration.
- High-Strength Structure: Tensile strength ≥ 200 MPa, flexural strength ≥ 150 MPa.
- Excellent Load-Bearing Capacity: Design safety factor ≥ 8, ensuring no deformation or leakage during full-load operation.
- Strong Impact Resistance: Falling ball impact strength ≥ 20 J, effectively withstanding mechanical shocks during operation.
- Excellent Durability: Designed service life ≥ 15 years under standard corrosive conditions.
- Anti-Aging Performance: Added with ultraviolet absorbers to prevent discoloration and chalking during outdoor use.
- Lightweight yet High-Strength: Density ranges from 1.6–1.8 g/cm³, with weight only 1/4 that of steel and 1/3 that of carbon steel, enabling easy installation.
- Maintenance-Free Design: Smooth surface prevents scaling; no regular anti-corrosion treatment is required, reducing maintenance costs by 70%.
- Integral Molding Process: Seamless tank connection, completely eliminating the risk of leakage.
- Anti-Static Design: Surface resistivity of 10⁶–10⁹ Ω, effectively preventing electrostatic accumulation.
- Structural Stability: Optimized via finite element analysis, with a seismic fortification intensity of up to Grade 8.

Stringent Production Control
- Raw Material Inspection: 100% inspection of resin viscosity, solid content and gel time
- Process Monitoring: Real-time monitoring of winding tension, lay-up angle and curing degree
- In-process Inspection: Quality check at each working procedure and establishment of traceable records
- Factory Acceptance Inspection: 100% water-filling test with 24-hour pressure maintaining and zero leakage
- Performance Testing: Random sampling for mechanical property and chemical property testing
- On-site Acceptance: Provision of installation guidance and assistance for customers to complete final acceptance
- Solution Design: Provision of optimal configuration solutions based on process requirements
- Installation Guidance: Dispatching technical personnel for on-site installation and commissioning guidance
- After-sales Maintenance: Provision of lifetime technical consultation and maintenance support
