Corrosion-Resistant Structured Packing China

Corrosion-Resistant Structured Packing for Demanding Industrial Applications

Introduction

In chemical processing, oil refining, and gas treatment, equipment often faces harsh conditions involving corrosive media, high temperatures, and aggressive chemical environments. Wangdu (Hebei) Chemical Engineering Co., LTD provides corrosion-resistant structured packing designed to maintain performance and durability in challenging separation processes.

This article discusses the materials, design features, and industrial applications of corrosion-resistant structured packing, along with key selection criteria.

Why Choose Corrosion-Resistant Structured Packing?

Standard structured packing materials may degrade when exposed to acids, alkalis, chlorides, or high-temperature steam. Corrosion-resistant structured packing is engineered to withstand such conditions while maintaining:

• Long-term structural integrity

• Consistent mass transfer efficiency

• Low pressure drop characteristics

• Reduced maintenance requirements

Materials for Corrosion Resistance

Wangdu (Hebei) Chemical Engineering Co., LTD offers structured packing in the following corrosion-resistant materials:

1. Stainless Steel (SS 304, 316, 316L, 904L)

• Resistant to acids, chlorides, and oxidizing environments.

• Suitable for refining, petrochemical, and chemical processing.

2. Titanium & Titanium Alloys

• Excellent resistance to seawater, chlorides, and acidic solutions.

• Used in offshore gas processing and marine applications.

3. Nickel-Based Alloys 

• High resistance to sulfuric acid, hydrochloric acid, and other aggressive chemicals.

• Common in sulfuric acid plants and chemical reactors.

4. Plastic (PP, PVDF, PTFE-Lined)

• Lightweight and resistant to acids, alkalis, and solvents.

• Ideal for wastewater treatment and pharmaceutical industries.

5. Ceramic (Alumina, Silicon Carbide)

• Withstands extreme temperatures and highly corrosive media.

• Used in high-temperature gas scrubbing and sulfuric acid production.
