Pickling Tank

Product Details

At Kishna Fiber Plast & Fabrication, we manufacture high-quality Pipe Coil Pickling Polypropylene (PP) Tanks designed specifically for the pickling process of pipes and coils. These tanks are essential for removing impurities such as rust, scale, and oxides from metal surfaces before further processing like galvanizing or coating. Our PP tanks offer excellent chemical resistance and durability, ensuring a long service life in industrial environments.

Key Features:

1. Superior Chemical Resistance:

Made from high-grade polypropylene, our tanks are built to withstand the harsh acids and chemicals used in the pickling process, such as hydrochloric acid, sulfuric acid, or other cleaning agents, ensuring corrosion resistance and extended longevity.

2. Customized Design for Pipe and Coil Handling:

The tanks are designed to accommodate pipes and coils of various sizes. We provide custom shapes and dimensions based on your production needs, ensuring efficient and safe handling of large metal items during the pickling process.

3. Durable and Leak-Proof Construction:

Using advanced welding techniques such as butt welding and extrusion welding, our PP tanks feature seamless joints, ensuring leak-proof performance and structural integrity. This is critical for handling corrosive pickling solutions over extended periods.

4. Heat and Temperature Resistance:

Our tanks are capable of withstanding high operating temperatures often required in the pickling process, without warping or degrading, ensuring consistent performance and reliability during thermal treatments.

5. Low Maintenance and Easy to Clean:

The smooth surface of polypropylene prevents chemical buildup and makes the tanks easy to clean. The non-stick properties reduce contamination, ensuring efficient operation and minimal downtime.

6. Reinforcement for Heavy-Duty Applications:

For large-scale industrial operations, our tanks can be reinforced with additional supports or steel frameworks to handle the weight of heavy pipes, coils, and chemical solutions.

7. Integrated Fittings and Accessories:

Our tanks come equipped with necessary fittings like inlets, outlets, and drain valves for easy handling of chemicals. We also offer custom accessories such as covers, heating systems, and agitation mechanisms to enhance the pickling process.

8. Environmentally Friendly Material:

Polypropylene is a recyclable material, making our tanks an eco-friendly choice for industries looking to reduce their environmental impact.

Steps in the Pickling Process:

Surface Preparation:

Before pickling, the metal surface may require preliminary cleaning to remove oils, greases, and other contaminants. This can be done using solvent cleaning or alkaline degreasing methods.

Pickling Solution:

The pickling solution typically consists of a strong acid, most commonly hydrochloric acid (HCl) or sulfuric acid (H₂SO₄). Other acids, such as phosphoric acid, may also be used depending on the specific application and metal type.

Immersion in Pickling Solution:

The metal workpiece is immersed in the pickling tank containing the acidic solution. The duration of immersion can vary based on factors like the type of metal, the concentration of the acid, and the thickness of the oxide layer being removed.

Chemical Reaction:

The acid reacts with the oxides and rust on the metal surface, converting them into soluble salts that can be easily washed away. This reaction typically leads to the formation of gas bubbles, which helps to dislodge the oxides.

Rinsing:

After pickling, the metal is thoroughly rinsed with water to remove any residual acid and dissolved impurities. This step is crucial to prevent any further corrosion or damage to the metal surface.

Neutralization (Optional):

In some cases, a neutralization step may be employed using a basic solution (like sodium bicarbonate) to neutralize any remaining acid on the metal surface.

Drying:

The cleaned and rinsed metal is then dried, either through air drying or using heat, to prevent oxidation before subsequent processing.

Post-Pickling Treatment:

Depending on the application, further treatments such as passivation (especially for stainless steel) or coating may be performed to enhance corrosion resistance.

Applications:

- Pickling of Metal Pipes and Coils:

Designed specifically for use in pickling processes where metal pipes and coils are immersed in acidic solutions to remove rust, scale, and other impurities.

- Surface Treatment:

Suitable for industries like steel manufacturing, pipe production, and metal processing, where surface preparation is crucial before coating, galvanizing, or further fabrication.

Our Pipe Coil Pickling PP Tanks offer a reliable and cost-effective solution for industrial pickling processes, ensuring the efficient removal of impurities while safeguarding the structural integrity of your tanks.
