What is Titanium Flanges?
Titanium flanges and fittings have become quite popular in recent years across several industries. They are built under the ASTM or ASME B381 material specification, and their dimensions can be fully customized according to the requirements specified.The titanium flanges can be a great choice when strength to weight ratio is an issue. Titanium is known for its strength and the flanges made with it also possess high strength.
Titanium grade 2 flanges are the most commonly requested pipe across different industries. Apart from having a high strength, they are also known for their corrosion resistance. They are widely used in marine equipment due to their oxidation resistance, and one of the best things about this material is that they retain their properties even at elevated temperatures. Titanium grade 12 material is known for its high weldability and malleability. Titanium flanges are one of the most popular choices for high temperature and high pressure services, but they come at a reduced weight. These flanges are used in the military equipment and aerospace industry. The flanges show good corrosion resistance in marine and chloride environments, and that is why they are popularly used as an assembly for heat exchangers or a component of offshore oil drilling machineries.
The titanium material also comes with high formability and enhanced workability. They can be both hot and cold formed, and during these procedures, they will be able to retain their mechanical properties.Titanium weighs almost 40-45% less than your regular stainless steel flanges, which helps them be easier to handle during the welding or installation period. Thus, using the titanium flanges once can expect to get better performances with convenience.
The highlights of the titanium flanges are as follows:
Titanium Grade 2 Flanges Vs Titanium Grade 5 Flanges
The titanium grade 2 flanges is made of the grade 2 titanium which is a commercial pure alpha alloy. It has great corrosion resisting properties especially in a wide range of aggressive media. The grade 2 material might be preferred over grade 5 material where aqueous corrosion is an issue. The grade 2 titanium also comes with high formability compared to grade 5.
The titanium grade 5 material can be described as an alpha beta alloy, which can be heat treated to give medium to high strength. It has a limited hardenability and that is why any section which is above 25mm thick might not develop the desired properties. They come with good weldability and hot formability. However, when it comes to hot forming, their degree is limited.
Ti Grade 2 Slip on Flange Vs Titanium Gr 5 RTJ Flanges
The Ti grade 2 slip on flanges are metallic rings that are slipped over to the ends of the pipe. They are then joined to the piping system through double welds, both from inside and outside. This helps to make the piping system leak-proof. The grade 2 flanges are mostly used in corrosive environments, as they can resist it effectively. However, they are capable of tackling low-pressure flows where there is a less leakage risk.
The Titanium Gr 5 RTJ Flanges have high strength and hence they are used for applications that involve high temperature and pressure. The ring type joint flange is a machined metallic ring that has deep cuts and grooves in its face. They help in giving leak-proof connections by establishing a strong seal.
Does Ti Grade 5 Flange rust or corrode?
The Ti Grade 5 Flange has corrosion resisting properties but the grade 2 titanium material offers better performances in such conditions.

Titanium grade 2 Flange corrosion resistance is due to the formation of a strongly adhering, stable, protective oxide film in the presence of oxygen. This film protects commercially pure titanium grades against most oxidising, neutral, and inhibited reducing conditions, as well as slightly reducing situations. Ti Grade 2 Flange is highly resistant to seawater and marine atmospheric corrosion. Corrosion resistance is similar among the four C.P. grades, however mechanical qualities differ due to differences in oxygen and iron concentration.
