Titanium exhibits excellent corrosion resistance in oxidizing and fluorinated media, resists impurities with reducing acids, and is highly resistant to pitting, intergranular corrosion, and stress corrosion. These properties make it indispensable in chemical equipment manufacturing. Below are key application examples.

Advantages of Titanium in Chemical Processes

Extended Equipment Lifespan: Reduces maintenance downtime and production losses.

Lower Operating Costs: Minimizes harmful impurities (e.g., iron) in products.

Applications

1.Titanium-Lined Vessels:

Used for evaporation, distillation, or reactions in weakly acidic or chloride-containing solutions.

Suitable for nitration of organic materials with nitric acid and other oxidative chemical processes.

Handles chromic acid solutions and sulfurized chromic acid at varying temperatures.

2.Catalytic Oxidation:

Copper and fluoride-containing solutions catalyze chlorocarbon oxidation at specific pH levels.

Equipment for catalytic processes at 150–200°C includes titanium-lined towers, pipelines, valves, and acid pumps (rotor-stator assemblies made of engineering-grade titanium).

3.Acetic Acid Purification:

Titanium distillation towers and components dominate multi-stage fractionation processes.

4.Serpentine Heaters:

Titanium coils prevent metal sulfate formation, offering 30% higher thermal conductivity than aluminum-plated copper coils.

5.Urea Reactors:

Titanium reactors (43m diameter, 8.2m length) withstand 120°C and 130 kPa for carbon black recovery and stress relief, handling chlorine and other gases.

6.Electrolysis:

Titanium cathodes with fine-grained starter plates improve copper electrolysis efficiency.

Expansion into Petrochemicals

Desalination: Titanium-clad thin-film evaporators produce freshwater from seawater.

Organic Acid Production: Titanium equipment ensures purity and durability.

Key Examples:

Welded Titanium Pumps and Heat Exchangers: Proven reliable in harsh environments.

Titanium-Clad Components: Widely used in crude oil refining and organic acid synthesis.
