Composite Titanium-Steel Tube Sheet

A titanium steel composite plate is a high-performance material manufactured by bonding titanium and steel plates through advanced processes such as explosive bonding or hot rolling. Explosive bonding utilizes high-pressure shock waves to create a metallurgical bond between the two metals, while hot rolling achieves a strong, uniform bond by applying heat and mechanical pressure.

Titanium is widely used in chemical reaction vessels, heat exchangers, and corrosive environments due to its exceptional corrosion resistance. However, its high cost makes it impractical for large-scale structural applications. Titanium steel composite plates solve this problem by combining titanium’s corrosion resistance with steel’s structural strength and affordability, significantly reducing material costs while maintaining performance.

- Base Material: Steel

- Cladding Material: Titanium

- Cladding Thickness: 0.3mm – 15mm

- Total Thickness: >4mm

- Delivery Condition: Blasted, blasted-rolled, rolled

1. Superior Corrosion Resistance Titanium naturally forms a dense oxide film when exposed to oxygen, providing excellent protection against corrosion. This passive layer makes titanium highly resistant to: - Acids, alkalis, and salt solutions - Oxidizing media - Chloride ion environments (superior to 304/316L stainless steel)

2. Cost Efficiency The titanium layer (typically 3–12mm thick) provides corrosion resistance, while the steel substrate offers structural support at a lower cost. Compared to pure titanium plates, titanium steel composites reduce expenses by 35–50%.

3. Lightweight Design Titanium has a lower density than steel, making titanium-steel composite plates lighter than solid steel plates of the same dimensions. This reduces the overall weight of heat exchangers and minimizes stress on supporting structures—ideal for offshore platforms, mobile equipment, and aerospace applications.

4. High-Temperature & Pressure Stability The composite structure maintains excellent mechanical strength and thermal stability, making it suitable for demanding industrial environments.

Titanium steel composite plates are widely used in industries requiring corrosion resistance, structural integrity, and cost efficiency, including:

1. Petrochemical Industry

- Concentration towers, reactors, heat exchangers

- Pressure vessels, condensers

- Shell-and-tube heat exchangers (most common application for titanium clad tube sheets)

2. Power Generation & Desalination

- Condensers in power plants

- Heat exchangers in seawater desalination systems

3. Salt Production Equipment

- Evaporator shells (resistant to salt scale buildup, extending maintenance cycles)

- Chloride solution handling systems

4. Metallurgical Engineering

- Reactors for wet pressure acid leaching

- Processing of cobalt-nickel sulfide concentrates, laterite nickel ore, and precious metal slags

5. Emerging Applications

- Wastewater treatment systems

- Marine and offshore engineering

Titanium steel composite plates offer an optimal balance of performance and cost, combining titanium’s corrosion resistance with steel’s strength and affordability. Their lightweight, durable, and cost-effective nature makes them indispensable in industries ranging from petrochemicals to power generation and marine engineering.
