Titanium welding neck flanges with raised face (WN RF) are a type of flange that is commonly used in piping systems. They are designed to be welded to the end of a pipe, and provide a secure connection between two pipes or a pipe and a piece of equipment.
The term "raised face" refers to the fact that the flange has a raised area around the bore hole, which helps to center the gasket and provide a more secure seal. This raised area is typically 1/16" to 1/4" high, and extends beyond the bolt holes.
Welding neck flanges have a long tapered hub, which allows for easy alignment and welding to the pipe. The tapered design also reduces the stress concentration at the base of the flange, making it less susceptible to cracking and other types of damage.
Titanium is a popular material for flanges due to its excellent corrosion resistance and strength-to-weight ratio.

Titanium welding neck flanges with raised face (WN RF) are used in a variety of applications where high strength and corrosion resistance are required. Here are some examples of where these flanges might be used:
1.Chemical industry: Titanium WN RF flanges are commonly used in the chemical industry, where they are used to connect pipes and equipment that are exposed to highly corrosive chemicals. The raised face design helps to provide a secure seal, while the titanium material offers excellent corrosion resistance.
2.Oil and gas industry: Titanium WN RF flanges are also used in the oil and gas industry, where they are used to connect pipelines that transport oil and gas over long distances. The flanges are often used in offshore applications, where they are exposed to harsh environments such as saltwater and extreme temperatures.
3.Aerospace industry: The aerospace industry requires lightweight, strong and corrosion-resistant materials for its components. Titanium WN RF flanges are used in aerospace applications where weight reduction is critical, such as in the construction of aircraft fuel tanks and other components.
4.Medical industry: Titanium WN RF flanges are also used in the medical industry, where they are used to connect pipes and equipment in medical gas delivery systems. The titanium material is non-toxic and biocompatible, making it suitable for use in medical applications.
Overall, titanium WN RF flanges are widely used in industries where high strength and corrosion resistance are required, as well as in applications where weight reduction is critical. Proper selection and installation of these flanges is important to ensure a safe and reliable connection.
