Titanium and Titanium Alloys Polyurethane Insulated Pressure Vessels

Titanium polyurethane insulated pressure vessels combine the exceptional corrosion resistance and lightweight properties of titanium with the thermal efficiency of polyurethane foam insulation. These vessels are fabricated from commercially pure titanium and titanium alloys for applications requiring superior resistance to chlorides, oxidizing acids, and seawater.

Why Choose Titanium and Titanium Alloys for Polyurethane Insulated Pressure Vessels?

Titanium is essential for applications involving chlorides, wet chlorine, hypochlorites, and oxidizing acids where other materials experience rapid corrosion. Its passive oxide film provides exceptional protection, and its lightweight (60% of steel density) reduces structural loads and transportation costs for large equipment.

Titanium and Titanium Alloys Polyurethane Insulated Pressure Vessel Applications

Common applications include:

• Chlor-alkali processing
• Wet chlorine service
• Bleach plant equipment
• Seawater heat exchangers
• Nitric acid processing
• Desalination equipment

Titanium and Titanium Alloys Polyurethane Insulated Pressure Vessel FAQs

What environments are best suited for titanium pressure vessels?

Titanium excels in oxidizing environments including wet chlorine, chlorine dioxide, hypochlorite solutions, and nitric acid. It provides excellent seawater corrosion resistance and is ideal for chlor-alkali, pulp bleaching, and desalination applications. Titanium is not suitable for reducing acids without oxidizers or dry chlorine gas.

What special considerations apply to titanium vessel fabrication?

Titanium fabrication requires inert gas shielding (argon) during welding to prevent oxygen and nitrogen contamination. All tooling must be dedicated to titanium to prevent iron contamination. Heat treatment is typically not required for commercially pure grades. Special procedures prevent galling at mechanical joints.

Is titanium cost-effective for pressure vessel applications?

Despite higher material cost, titanium can be cost-effective due to superior corrosion resistance eliminating maintenance and replacement costs. Lower density reduces structural support requirements. Titanium clad construction provides an economical alternative for larger vessels, combining titanium’s corrosion resistance with carbon steel structural strength.
