PP Pickling Tank
PP pickling tank and corrosion-resistant process tank for acid and alkali treatment lines.
SKU: RST-PP-PICKLING
Product Details
Corrosion-Proof Thermoplastic Chemical & Surface Treatment Basins
Our PP (Polypropylene) Pickling Tanks are custom-fabricated process vessels designed specifically for hot acid pickling, metal cleaning, electroplating, and chemical etching applications. Utilizing prime-grade polypropylene plate materials joined via advanced CNC automatic hot-melt welding, our tanks offer exceptional chemical inertness, seamless leak proofing, and high structural longevity.
Key Features & Advantages
- Complete Acid & Alkali Inertness: Superior resistance to hot hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric-hydrofluoric acid blends (HNO3/HF), and caustic solutions.
- Seamless Hot-Melt Welding: Fabricated using automated extrusion welding technology to ensure maximum seam strength and zero leakage risk.
- Reinforced External Structure: Heavy-duty external steel tube reinforcement wrapped in protective PP profiles prevents tank wall deflection under full fluid load.
- High Thermal Insulation: Excellent natural thermal insulation properties reduce heat loss from hot pickling solutions, saving energy costs.
- Custom Configurations: Tailor-made dimensions with integrated options like lip exhaust hoods, heating coils, liquid level sensors, and bottom drain valves.
