Titanium Custom Insulated Pressure Vessels

Roben, Mfg, Inc. is a leading manufacturer of titanium custom insulated pressure vessels, delivering exceptional corrosion resistance and performance for specialized industrial applications. Our titanium insulated vessels combine the unique properties of commercially pure and alloyed titanium with advanced insulation systems for reliable operation in aggressive chloride and seawater environments.

What is a Titanium Custom Insulated Pressure Vessels?

A titanium custom insulated pressure vessel is a closed container fabricated from titanium and its alloys, designed to withstand highly corrosive environments, particularly those involving chlorides, seawater, and oxidizing acids. Titanium’s exceptional strength-to-weight ratio and corrosion resistance make it ideal for demanding applications where other materials fail.

Titanium offers unique advantages including complete immunity to seawater and chloride corrosion, excellent resistance to oxidizing acids, and remarkably low density combined with high strength. When properly designed with appropriate insulation systems, titanium vessels provide decades of reliable service in the most challenging chemical environments.

Titanium Material Properties

• Outstanding Chloride Resistance: Titanium is virtually immune to chloride pitting, crevice corrosion, and stress corrosion cracking.
• Superior Seawater Performance: Titanium requires no cathodic protection and resists marine fouling better than other metals.
• Excellent Strength-to-Weight Ratio: Titanium provides steel-like strength at approximately 55% of the weight.
• Oxidizing Acid Resistance: Titanium withstands wet chlorine, chlorine dioxide, nitric acid, and other oxidizing media.
• Biocompatibility: Titanium is non-toxic and suitable for pharmaceutical and food processing applications.
• Long Service Life: Exceptional corrosion resistance enables service life exceeding 40 years in aggressive environments.

Titanium Grades and Options

• Grade 1: Commercially pure titanium with maximum formability and corrosion resistance for low-strength applications.

Titanium Custom Insulated Pressure Vessels Frequently Asked Questions (FAQs)

Why is titanium preferred for seawater applications?

Titanium is virtually immune to seawater corrosion and biofouling. Unlike copper alloys which require velocity limits to prevent erosion-corrosion, titanium handles high velocities without damage. Titanium equipment in seawater service typically lasts 40+ years without measurable corrosion, eliminating costly replacements and shutdowns.

What are the limitations of titanium vessels?

Titanium should be avoided in reducing acid environments without oxidizers, dry chlorine gas (which can cause ignition), and fluoride-containing solutions. Titanium also requires attention to galvanic compatibility when connected to other metals. Our engineering team evaluates all service conditions to ensure titanium is appropriate for your application.

How does titanium compare economically to nickel alloys?

Titanium typically costs less than premium nickel alloys like Hastelloy C-276 while offering superior performance in many chloride environments. When combined with its longer service life and lower maintenance requirements, titanium often provides the lowest total cost of ownership for seawater and chloride service applications.

Can titanium vessels be repaired in the field?

Yes, titanium can be field welded with proper equipment and qualified procedures. Inert gas shielding is critical to prevent oxygen contamination during welding. We provide repair procedures and can supply qualified field welding teams for on-site repairs if needed.
