Heavy-Duty Pickling Enclosures Built for Longevity

During the batch hot-dip galvanizing process, pretreatment pickling produces high concentrations of acid fumes (HCl/H₂SO₄) that cause severe workplace hazards, building corrosion, and environmental non-compliance.

Tianjin Resense designs and manufactures fully enclosed, automated pickling rooms tailored for batch hot-dip galvanizing plants. By integrating heavy-duty anti-corrosion structural design, high-velocity exhaust extraction, and advanced acid mist scrubbing systems, our pickling enclosures maintain a clean plant environment while maximizing pre-treatment productivity.

Key Features & Technical Advantages

1. 100% Acid Fume Extraction & Zero Leakage

• Negative Pressure System: Engineered with dynamic seal mechanisms and negative pressure ventilation to ensure zero acid gas escape during loading, dipping, and transfer.

• Integrated Scrubber System: Multi-stage polypropylene (PP) acid mist scrubbers reduce HCL mist emission to under 10mg/ m³ exceeding stringent European and international environmental standards.

2. High-Performance Anti-Corrosion Structural Materials

• Heavy-Duty Shell: Built using high-density Polypropylene (PP), Fiberglass Reinforced Plastic (FRP), or specialized anti-corrosion coated steel frame structures for extended service life (>15 years).

• Transparent Observation Windows: Impact-resistant, acid-proof polycarbonate panels enable safe real-time visual inspection without opening the enclosure.

3. Seamless Overhead Crane & Automation Integration

• Automated Crane Pass-Through: Custom-designed roof lifting slots with automatic rubber or mechanical seals allow crane hoists to transfer steel components smoothly without leaking fumes.

• Smart Process Control: PLC-controlled automated door systems and hoist synchronization optimize pickling cycle time and reduce human acid exposure.

Frequently Asked Questions (FAQ)

Q1: Can Resense fit an enclosed pickling room into our existing galvanizing plant floor plan?

Yes. Every Resense pickling room is fully custom-engineered. Our engineering team conducts layout modeling based on your crane hoist path, tank arrangement, and roof height restrictions.

Q2: How does the pickling room withstand severe hydrochloric acid corrosion?

We utilize high-grade chemical-resistant polymers (such as PP-H and FRP) for structural panels, piping, and ducts. Structural steel components are treated with multi-layer heavy epoxy fluorocarbon coatings or completely isolated outside the acid vapor zone.

Q3: Does the system comply with environmental regulations in Europe or the Middle East?

Absolutely. Our acid mist treatment systems are designed to meet strict global emission standards, reducing acid exhaust content significantly below local environmental limits.
