Titanium and Titanium Alloy Pressure Vessels
Titanium and titanium alloys offer unmatched corrosion resistance in oxidizing chloride environments, combined with exceptional strength-to-weight ratio for specialized pressure vessel applications. Roben Manufacturing engineers custom titanium vessels for seawater service, chlorine dioxide bleaching, wet chlorine gas, and other oxidizing environments where nickel alloys and stainless steels are inadequate.
Application Importance
Oxidizing chloride environments present unique corrosion challenges that eliminate most metallic materials from consideration. Titanium forms a stable, self-healing oxide film that provides outstanding resistance to chloride pitting and crevice corrosion under oxidizing conditions. The material’s low density also makes it attractive for weight-sensitive applications. Roben Manufacturing provides specialized expertise in titanium vessel design and fabrication for these demanding applications.

Roben Manufacturing Expertise
With over 65 years of pressure vessel fabrication experience, Roben Manufacturing has developed specialized expertise in titanium vessel fabrication. Our titanium welding procedures utilize inert gas trailing shields and complete backpurge protection to prevent oxygen contamination. Clean handling procedures throughout fabrication prevent iron contamination that could compromise corrosion resistance.
Frequently Asked Questions
Why is titanium preferred for chlorine dioxide service?
Titanium’s oxide film provides exceptional resistance to oxidizing chloride compounds. In chlorine dioxide bleaching applications, titanium vessels routinely provide decades of service where stainless steel and nickel alloys would fail within months.
What are the challenges in titanium welding?
Titanium must be shielded from atmospheric contamination at temperatures above 500°F (260°C). Welding requires complete inert gas coverage including trailing shields and backpurge. Our welders are specifically qualified for titanium fabrication with procedures designed to ensure weld quality.
Is titanium-clad steel an alternative to solid titanium?
Yes. Titanium-clad steel plate provides titanium’s corrosion resistance at reduced cost by utilizing a thin titanium layer metallurgically bonded to a carbon steel substrate. This option is suitable for many applications and can significantly reduce material costs.
