The surface treatment process of concentric reducers

In the world of pipeline systems, concentric reducers play a crucial role in facilitating smooth flow transitions and optimizing performance. At Haihao Group, we take pride in our meticulous approach to manufacturing concentric reducers, which includes a comprehensive surface treatment process. In this article, we delve into the surface treatment techniques employed by our experts to enhance the durability, corrosion resistance, and aesthetic appeal of our concentric reducers, ensuring their longevity and optimal performance.

Protective Surface Treatment:

Passivation: Passivation is a chemical process applied to stainless steel concentric reducers. It removes impurities, iron contamination, and oxide layers that can potentially compromise the material’s corrosion resistance. Passivation enhances the surface’s integrity, extending the  concentric reducers’ lifespan and reducing the risk of corrosion in harsh operating conditions.

Pickling: Pickling is commonly employed for carbon steel concentric reducers. This process involves the removal of impurities, scales, and oxide layers from the surface using acid solutions. By eliminating these contaminants, pickling improves the concentric reducers’ resistance to corrosion, ensuring their performance and integrity over time.

Corrosion Protection and Coating:

Zinc Coating: Zinc coating, commonly known as galvanizing, is a widely used method for protecting concentric reducers from corrosion. It involves applying a layer of zinc to the surface, which acts as a sacrificial barrier against rust and environmental elements. Zinc-coated concentric reducers exhibit exceptional resistance to corrosion, making them ideal for demanding applications in various industries.

Epoxy Coating: Epoxy coating is a versatile and highly effective method for protecting concentric reducers from corrosion and chemical exposure. The coating is applied in multiple layers, providing a durable barrier that safeguards against harsh environmental conditions. Epoxy-coated concentric reducers offer excellent resistance to chemicals, abrasion, and impact, ensuring their long-term performance and reliability.

Powder Coating: Powder coating is an environmentally friendly surface treatment option for concentric reducers. It involves applying a dry powder to the surface, which is then heated to form a protective layer. Powder-coated concentric reducers not only exhibit excellent corrosion resistance but also offer enhanced aesthetic appeal, as they are available in a wide range of colors and finishes.

Aesthetic Enhancement:

Polishing: Polishing is an optional surface treatment process that enhances the aesthetic appeal of  concentric reducers. Through mechanical polishing techniques, the surface is smoothed and refined, creating a mirror-like finish. Polished concentric reducers not only provide a visually appealing appearance but also facilitate easy cleaning and maintenance.
