Forms of Titanium Grade 2 Pipes

Titanium Grade 2 pipes are supplied in 3 primary manufacturing forms.

  • Titanium Grade 2 Seamless Pipes
  • CP Ti Gr.2 Welded (EFW) Pipes
  • Ti Grade 2 ERW Pipes

All forms are delivered in annealed or cold-worked and stress-relieved condition.

Corrosion Resistance of Titanium Grade 2 Pipes

Titanium Grade 2 pipes resist general corrosion in seawater, brines, moist chlorine gas, alkaline solutions, and oxidising acids. The subsections below address 3 specific corrosion modes.

General Corrosion

The passive oxide film (TiO2) on Titanium Grade 2 pipe surfaces reforms instantly when damaged. The alloy withstands erosion velocities without degradation.

Crevice Corrosion

Crevice corrosion is the primary limiting factor for unalloyed titanium in hot chloride media. Grade 2 pipes remain resistant to crevice attack at temperatures below 80 °C in seawater.

Stress Corrosion Cracking

CP Ti Grade 2 resists chloride stress corrosion cracking. This resistance holds across the full operating temperature range of the alloy.

Industrial Applications of Titanium Grade 2 Pipes

Commercially pure Titanium Grade 2 pipes find use across 5 major industrial sectors where corrosion resistance, low density, and long service life justify the material cost. The sections below cover each application in detail.

Chemical Processing

Ti Gr 2 pipes carry acids, alkalis, and organic solvents through reactor vessels and heat exchangers. The alloy resists oxidising acids, including nitric and chromic acid, up to 70% concentrations.

Seawater and Desalination

Grade 2 titanium pipe handles seawater intake, brine discharge, and condenser tubing in desalination plants. The alloy is immune to chloride pitting at temperatures below 260°C.

Oil and Gas

Offshore platforms use this piping for firewater systems, seawater cooling loops, and produced water handling. Resistance to hydrogen sulphide makes this grade suitable for sour service.

Power Generation

Power plants use Titanium Grade 2 for condenser tubing and heat exchanger bundles. The alloy's resistance to brackish cooling water reduces maintenance intervals considerably compared to copper-nickel alternatives.

Pulp and Paper

Bleach plant piping benefits from Ti Gr 2's resistance to chlorine dioxide, hypochlorite, and wet chlorine gas. These pipes outperform stainless steel by a factor of 3 to 5 in bleaching environments containing chlorine.

Titanium Grade 2 vs Stainless Steel Pipes

The comparison below provides the key differences between Ti Gr 2 and common stainless steel pipe grades for corrosive service.

Property Titanium Grade 2 SS 316L
Density 4.51 g/cm3 8.0 g/cm3
Tensile Strength 345 MPa (50 ksi) 485 MPa (70 ksi)
Seawater Resistance Fully resistant up to 260 degrees C Susceptible to pitting above 40 degrees C
SCC Immunity Yes, all chloride environments No, fails in warm chlorides
Relative Cost Higher initial cost Lower initial cost
Lifecycle Cost Lower (3 to 5x longer service life) Higher (frequent replacement)

While the initial purchase price of Titanium Grade 2 is higher, the extended service life in chloride and seawater environments reduces total lifecycle cost significantly.

Frequently Asked Questions:

What schedules are available for Titanium Grade 2 Pipes? +
Titanium Grade 2 pipes come in SCH5, SCH10, SCH40 (STD), SCH80, and SCH160 per ANSI B36.19M and B36.10.
What is the price of Titanium Grade 2 Pipes per kg? +
Prices start from Rs 1,200 to Rs 1,600/kg in India ($17 to $24/kg internationally). The final prices vary with size, origin, and quantity. Contact us for current rates.
What is the difference between Titanium Grade 2 and Grade 5 Pipes? +
Grade 2 is commercially pure titanium with 345 MPa minimum tensile strength, superior corrosion resistance, and excellent weldability. Grade 5 (Ti-6Al-4V) is an alpha-beta alloy with 895 MPa minimum tensile but it costs more and has reduced weldability.
What is the maximum service temperature for Titanium Grade 2 Pipes? +
Titanium Grade 2 pipes are rated for continuous service up to 425 °C (800 °F).
Can Titanium Grade 2 Pipes be welded? +
Yes. Ti Gr 2 has excellent weldability using GTAW (TIG) with argon shielding gas. Filler metal should match Grade 2 composition per AWS A5.16 ERTi-2. Back-purging with argon is required to prevent oxidation.
Are Titanium Grade 2 Pipes resistant to seawater corrosion? +
Titanium Grade 2 pipes are fully resistant to seawater corrosion at temperatures up to 260 °C and immune to stress corrosion cracking in all chloride environments.
Is Grade 2 Titanium good for piping applications? +
Grade 2 is widely specified commercially pure titanium for industrial piping. It offers the best balance of corrosion resistance, formability, weldability, and cost among unalloyed titanium grades.
What is the difference between Titanium Grade 2 and 2H Pipes? +
Grade 2H has the same composition as Grade 2 but requires a higher minimum tensile strength of 450 MPa (65 ksi) compared to 345 MPa for standard Grade 2. Grade 2H is specified when tighter mechanical property control is needed for pressure vessel applications.
