Description
Heavy-Duty Industrial PVDF Pickling Tanks
Nikunj Fibre Glass manufactures heavy-duty PVDF Pickling Tanks in Vapi, Gujarat. Since 1992, our engineering team has designed specialized corrosion-proof processing equipment across India. Therefore, metallurgical plants and wire drawing units trust our robust pickling baths.
Polyvinylidene Fluoride provides outstanding mechanical strength and chemical stability. In addition, it easily withstands severe hot acid mixtures where PP or HDPE liners deform. Specifically, our tanks deliver continuous service up to 140°C (300°F) under aggressive nitric-hydrofluoric acid and chromic acid conditions.
Structural Steel Caged & Dual Laminate Designs
We fabricate both solid PVDF tanks with external mild steel frames and composite PVDF/FRP dual laminate vessels. For rectangular pickling lines, our steel framework bears all hydrostatic pressures. Consequently, the tank maintains perfect dimensional alignment and prevents wall bulging during heavy component immersion.
Key Advantages of PVDF Pickling Tanks
High-Temperature Resistance & Structural Toughness
- German Butt-Fusion Welded Construction: Our technicians weld PVDF plates using computerized German butt-fusion machines. Therefore, all tank joints achieve 100% homogenous bond strength without vulnerable joints.
- Unrivaled Mixed-Acid Resistance: The tank withstands hot Hydrofluoric Acid (HF), Nitric Acid (HNO3), and Chromic Acid. Consequently, it prevents environmental contamination and hazardous acid leaks.
- High Continuous Working Temperature: PVDF safely operates at bath temperatures up to 140°C. In contrast, standard polypropylenes experience accelerated stress cracking above 70°C.
- 100% Spark-Tested Liner Joints: We non-destructively test every weld using high-voltage 15 kV–20 kV spark testers before shipment. Thus, we guarantee leak-proof performance from day one.
- Custom Process Features: We integrate cascade overflow weirs, bottom sludge slopes, immersion heater bosses, and cathode bars. Furthermore, we supply matching lip extraction fume hoods and scrubber tie-ins.

Industrial Applications & Metal Finishing
Severe Chemical Processing Lines
Metal finishing plants specify our PVDF Pickling Tanks for aggressive processing. Because fluoropolymers resist acid oxidation, they deliver reliable operational safety:
- ✅ Stainless Steel Pickling Lines: Plants use these tanks for hot mixed nitric and hydrofluoric acid pickling. In particular, they withstand harsh descaling reactions.
- ✅ Hard Chrome & Electroplating Baths: They safely contain continuous hot chromic acid (CrO3) plating solutions. Meanwhile, non-stick walls prevent heavy sludge buildup.
- ✅ Wire Drawing & Tube Pickling: Facilities deploy long rectangular troughs for continuous wire coil descaling.
- ✅ Aerospace & Titanium Etching: High-grade PVDF liners resist concentrated acid etching reagents without metallic contamination.
- ✅ Acid Neutralization & Rinse Stations: Furthermore, facilities integrate cascade rinse tanks to conserve washdown water.

Frequently Asked Questions (FAQ)
Common Technical Inquiries
Q1: Why are PVDF Pickling Tanks preferred for stainless steel pickling?
Stainless steel pickling uses highly corrosive mixtures of nitric acid and hydrofluoric acid (HF) at elevated temperatures. Standard PP and FRP tanks degrade quickly in this harsh environment. In contrast, PVDF resists chemical penetration and withstands temperatures up to 140°C (300°F). Therefore, it provides unmatched service life.
Q2: How does the external structural frame support the PVDF pickling tank?
Our tanks incorporate an external framework made of heavy mild steel box sections with corrosion-resistant epoxy coating. Therefore, the structural cage absorbs all hydrostatic liquid pressure. Meanwhile, the inner PVDF liner serves as an impermeable chemical barrier. Consequently, the tank remains structurally stable without sagging.
Q3: Does Nikunj Fibre Glass manufacture custom pickling tanks with fume hoods in Gujarat?
Yes, Nikunj Fibre Glass fabricates custom rectangular pickling tanks from 500 Litres to 40,000 Litres at our Vapi GIDC plant. Moreover, we equip them with lip-extraction fume hoods, immersion heaters, and cascade weirs. Furthermore, we deliver expedited shipments to Ahmedabad, Surat, Vadodara, Ankleshwar, and nationwide across India.
