Titanium threaded flanges are best known for being strong, lightweight and corrosion resistant. One property that stands out when compared to other metal threaded flanges is that titanium threaded flanges have the highest strength-to-weight ratio with a density of 4.51 g /cm³. As an example, titanium grade 5 is 4 times stronger than 316 stainless steel at nearly half the weight. This makes titanium threaded flanges ideal for applications that require both lightness of weight and excellent strength such as oil & gas (down-hole), military and sporting goods. 

Titanium threaded flanges are also unique among metals in the chemical processing industry for handling chlorine (wet) and chlorine compounds in aqueous solutions. Titanium threaded flanges are fully resistant to solutions of chlorides, hypochlorites, chlorates, perchlorates and chlorine dioxide. As a result titanium threaded flanges are often using within the chlorine related industries such as pulp and paper and chlor-alkali / bleach.

Titanium threaded flanges are also an excellent material to prevent seawater corrosion. Because titanium threaded flanges can resists corrosion by seawater up to temperatures as high as 500°F (260°C) as well as survive at ocean depths over a mile below the surface, titanium threaded flanges are used throughout the oil & gas, desalination and marine industries.

The most common grades of Titanium threaded rods are Grade 2 and Grade 5. Gain more insight on these by accessing our Grade 2 and Grade 5 overviews or by contacting our engineering experts.

Titanium Threaded Flange Features & Benefits

Titanium threaded flanges have a tapered female thread to join the male threads of a pipe in order to create a tight seal. This type of flange is most ideal when post weld heat treatment is not possible in hazardous, flammable or explosive applications where welding is too dangerous. Titanium threaded flanges are also convenient in pilot processes whose configuration is often changed.

Threaded Flange Advangtages

• The main benefit is that that threaded seal eliminates the need for welding.
• As they do not require welding they save time and money to install.
• Allow for connections to be made in dangerous, explosive applications where welding is not possible.
• Useful connection in materials that are difficult to create a successful and strong weld.
• Ideal for connecting small diameter pipes.
• Systems could be easily reconfigured.

Threaded Flange Disadvantages

• They are not suitable where high temperatures, frequent cyclic conditions or bending stresses are likely in applications.

Titanium Weld Neck Flange Features & Benefits

Titanium weld neck flanges are best for hazardous, high pressure applications. Weld neck flanges are easily identified by their long tapered neck. The inside of the flange is bored to match the inside diameter of the pipe in order to ensure there is no restriction in flow and also to prevent turbulence at the joint. The tapered neck provides thicker metal at the flange joint, while the neck narrows down gradually to meet the pipe where it is butt welded to the pipe. This design helps to transfer stress from the flange to the pipe, as well as diminish stress concentration at the base of the flange connection.

Titanium weld neck flanges are ideal for critical applications involving high pressure, sub-zero and elevated temperatures, as well as in conditions where fluctuations cause pipe expansion/contraction.

Key Feature: Ideal for high presure applications.

Weld Neck Flange Advantages

• Ability to withstand high pressure – since pipe is welded to the neck of the flange, stress is transferred to the pipe.
• The beveled end that, when connected to a pipe, creates a trough for a strong weld.
• Most versatile flange in the ASME stable of flanges.

Weld Neck Flange Disadvantages

• More advanced welding skill is needed for installation. The inside weld must be smooth to reduce friction and the outside weld must meet code criteria.

Uses

• Severe conditions that include high-pressure, high-cyclic and hazardous fluid applications.
• Fitting-to-fitting fabrication where the flange is welded directly to a fitting, such as an elbow, without the need for a short piece of pipe, as would be required with a slip-on flange.
