Pickling Treatment for Pipes and Tubes: Enhancing Durability and Performance

In various industries, including oil and gas, manufacturing processes play a crucial role in ensuring the durability and performance of products. When it comes to pipes and tubes, one important treatment method that significantly enhances their quality is pickling. Pickling treatment involves the removal of impurities and scale from the surface of metals, resulting in clean and corrosion-resistant pipes and tubes. At Ascent Tubular Products, employees at the Bristol, Tn. facility use pickling to ensure products meet the standards of all customers.

Understanding Pickling Treatment: Pickling is a chemical process used to remove oxide scales, rust, and other impurities from the surface of metals, including pipes and tubes. Typically, a pickling solution, which consists of acids such as hydrochloric acid or sulfuric acid, is applied to the metal surface. The acid reacts with the impurities, dissolving them and leaving behind a clean surface. After pickling, the pipes and tubes undergo thorough rinsing and neutralization to remove any residual acid.

Benefits of Pickling Treatment:

1) Removal of Scale and Oxide Layers: During the manufacturing process, pipes and tubes often develop oxide layers and scale due to exposure to high temperatures, welding, or other industrial processes. These impurities can compromise the structural integrity of the metal and increase the risk of corrosion. Pickling treatment effectively removes these layers, leaving behind a clean surface that is free from impurities. This not only enhances the visual appearances of the pipes and tubes, but also improves their mechanical properties.

2) Corrosion Resistance: Corrosion is a significant concern in various industries, especially in environments where pipes and tubes are exposed to corrosive substances or harsh conditions. Pickling treatment creates passivated surface by removing impurities and creating a protective layer of the metal. This protective layer acts as a barrier against corrosion, enhancing the longevity and performance of the pipes and tubes. By reducing the risk of corrosion, pickling treatment contributes to cost savings by minimizing maintenance and replacement needs.

3) Improved Weldability: Welding is a common process used in the fabrication of pipes and tubes. However, oxide layers and scale on the metal surface can impede the welding process and compromise the integrity of the joint. Pickling treatment removes these impurities, ensuring a clean and smooth surface that promotes better weldability. This results in a stronger and more reliable weld joints, minimizing the risk of leaks or failures in the pipes and tube system.

4) Surface Preparation for Coating or Plating: In certain applications, pipes and tubes may require additional protective coatings or plating to enhance their resistance to corrosion or provide specific properties. Pickling treatment serves as an essential step in surface preparation before applying these coatings. By removing impurities and creating a clean surface, pickling treatment ensures optimal adhesion and performance of the applied coatings, maximizing their effectiveness in protecting the pipes and tubes.

Pickling treatment plays a vital role in the manufacturing process of pipes and tubes, and the Ascent Tubular team integrates this process seamlessly to ensure the product being shipped meets all quality standards. With capabilities to produce product up to 40ft in length – which helps decrease the amount of welding needed – and small diameter product ranging from 3/8” to 114in”, Ascent Tubular Products will certainly have the quality product to meet any challenging project.
