Titanium Ferrule Fittings

Titanium ferrule fittings

What are the advantages of using Titanium Ferrule Fittings in high-temperature?

Titanium Gr5 double ferrule fittings get coveted in marine industries, medical instruments, and power generation.

  • They are easy to install and can handle temperatures up to 800°F.
  • The high strength-to-weight ratio of Ti makes it cost-effective over time.
  • Titanium ferrule fittings can manage flowing seawater, impingement, and stress corrosion.
  • Easy machinability helps clients adapt this material to their unique needs.
  • They can sustain high pressures and vibrations in piping.

Note that the corrosion resistance of a UNS R56400 ferrule fitting does not cover (even dilute) hydrofluoric acid; it can cause cracking and embrittlement.

What is the difference between Grade 2 and Grade 5 Titanium Ferrule Fittings?

Titanium Gr2 ferrule fittings refers to commercially pure titanium (over 98.9%). Grade 5 differs in its chemical composition and possesses superior metallurgical properties. They also get called Ti-6AL-4V tube fittings because of the included aluminium and vanadium (6 and 4%).

  Grade 2 Grade 5
Strength 344 MPa Higher (950 MPa)
Can be age-hardened for more strength
Cost Lower Expensive
Scratch Resistance Lower Excellent
Machinability Higher Lower

Although Grade 5 can deliver enhanced properties for some sectors, Ti Gr 2 DIN 3.7165 instrumentation fittings are also excellent options for pharmaceuticals, gas processing, and heat exchangers.

What are the most common testing methods used to ensure the quality and reliability of Titanium Ferrule Fittings? How do they differ from one another?

These robust components undergo different tests, including destructive and non-destructive. While ASTM B338 titanium tube fittings can get assessed via traditional approaches like Charpy impact tests, contemporary methods include optical emission spectrometry and X-ray fluorescence testing.

fluorescence testing. Destructive tests on titanium instrumentation fittings include static, impact, and cyclic procedures. These products get thoroughly examined for pitting resistance, intergranular corrosion, hardness, and chemical composition, via spectrometry.

Mechanical tests on titanium grade 5 compression fittings cover essential characteristics like tensile strength and elongation.
