Frequently Asked Questions

Why is titanium used for deepwater risers?

Titanium's high strength-to-weight ratio (50% lighter than steel) dramatically reduces the weight of deep-water drilling riser strings, enabling drilling in ultra-deep water exceeding 3000m.

Is titanium resistant to sour gas (H₂S)?

Yes, standard Ti-6Al-4V is resistant to H₂S at moderate temperatures. For more severe sour conditions, Grade 29 (with ruthenium addition) provides enhanced resistance per NACE MR0175.

What is the advantage of titanium fire-water piping?

Titanium fire-water piping on offshore platforms requires zero maintenance over 25+ year platform life. Steel fire-water pipes corrode internally and must be replaced every 5-7 years, costing millions in offshore shutdown time.

Which titanium alloy is used for subsea umbilicals?

Grade 9 (Ti-3Al-2.5V) is the standard alloy for subsea umbilical tubing due to its excellent combination of strength, fatigue resistance under dynamic loading, and cold workability for tube forming.

Do you comply with NACE MR0175 for sour service?

Yes, all our oil & gas titanium products are supplied in compliance with NACE MR0175/ISO 15156 for sour service environments. Material is tested and certified for SSC and SCC resistance.
