Titanium Pipes

Engineering Product Reference for Corrosion-Resistant Piping Systems

Titanium pipes are used in pressure-containing and fluid transport systems where corrosion resistance, structural integrity, and long-term reliability are critical.
Unlike heat exchanger tubes, titanium pipes are selected based on pressure rating, system design, and code compliance, rather than heat transfer efficiency.

This page explains the engineering role, selection logic, and application scope of titanium pipes.

1. Role of Titanium Pipes in Engineering Systems

Titanium pipes are typically used where:

  • Fluids must be transported under pressure

  • Corrosive media are present (seawater, brine, chemicals)

  • Long service life and low maintenance are required

  • System integrity is more critical than compactness

Typical systems include process piping, cooling water lines, chemical transfer lines, and offshore piping systems.

2. Titanium Pipes vs Titanium Tubes – Engineering Difference

From an engineering standpoint, pipes and tubes serve different functions.

Engineering rule

If pressure containment governs design, pipes—not tubes—should be specified.

3. Seamless vs Welded Titanium Pipes

Seamless Titanium Pipes

  • Uniform structure without weld seam

  • Preferred for high-pressure or critical service

  • Excellent reliability in corrosive environments

Welded Titanium Pipes

  • Manufactured from plate or strip

  • Suitable for larger diameters and lower pressure

  • Requires strict weld quality and inspection

Selection depends on pressure class, diameter, and system criticality.

4. Titanium Grade Selection for Pipes

Grade selection must reflect corrosion severity and operating conditions.

Commonly Used Grades

  • Grade 2 – Baseline choice for most piping systems

  • Grade 16 – Used where moderate corrosion uncertainty exists

  • Grade 7 – Selected for severe corrosion, low-flow, or crevice-prone systems

  • Grade 5 – Used only when mechanical strength dominates and corrosion is controlled

Engineering rule

Do not select Grade 5 for piping solely based on strength without corrosion evaluation.

5. Typical Applications of Titanium Pipes

Titanium pipes are widely used in:

These applications emphasize system reliability over initial cost.

6. Design and Installation Considerations

When designing titanium piping systems, engineers should consider:

  • Pressure rating and wall thickness selection

  • Thermal expansion and support design

  • Galvanic isolation from dissimilar metals

  • Proper gasket and flange compatibility

  • Avoidance of stagnant zones

Proper piping design is essential to fully realize titanium’s corrosion resistance.

7. Fabrication and Welding Notes

Titanium piping fabrication requires:

  • Clean working environment

  • Inert gas shielding during welding and cooling

  • Qualified welding procedures

  • Controlled heat input

Improper fabrication can compromise corrosion resistance, even with the correct grade.

8. Inspection, Testing, and Certification

Titanium pipes are commonly supplied with:

  • Chemical composition verification

  • Mechanical testing

  • Non-destructive testing (UT / RT / PT as specified)

  • Dimensional inspection

Typical standards include:

  • ASTM B861 – Seamless titanium pipe

  • ASTM B862 – Welded titanium pipe

  • ASME SB equivalents for code piping

Certification is usually provided per EN 10204 3.1 or 3.2.

9. Lifecycle Value of Titanium Pipes

In corrosive piping systems, titanium pipes offer:

  • Long-term resistance to corrosion-related failure

  • Reduced maintenance and replacement

  • Improved system availability

  • Lower total cost of ownership

Titanium pipes are often selected to eliminate corrosion as a system design variable.
