The most obvious advantage of using various grades of Titanium Flanges as opposed to their more conventionally used steel counterpart is that they have a lower density and therefore are light in weight. Although the metal is light in weight, the Titanium Blind Flange has the ability to withstand elevated temperatures as well as high pressures, especially when involved in piping systems. Typically a blind flange is used to block vessels or a nozzle and hence the activity in the system creates a lot of stress. Since the Titanium RTJ Flange has good tensile strength and toughness properties the metal can be considered as a quintessential part of many systems.
Titanium Flanges
Titanium Alloy Blind Flange
Ti Alloy WNRF Flange
However, it must be noted that while titanium is a metal that is strong, its commercially pure grades i.e. grade 1 - 4 tend to be ductile and are soft, which is why most suppliers across demanding fields would prefer using a titanium based alloy or stainless steel or a carbon steel substitute while choosing flanges for applications. Very commonly, a Titanium Alloy Blind Flange is used to not only test the flow of gas but also liquid through either a pipe or vessel.
Designed for high pressured applications based in either cold or elevated temperature settings the Titanium WNRF Flange can be identified by their long tapered hub. More often than not, the Ti alloy Buttweld Stub End is used to connect flanges & pipes and are often used in combination of a welding process. The Titanium Spectacle Blind Flange is applied to piping systems in order to permanently separate them.
