About This Product
Threaded Flanges
GS MetalFit supplies Threaded Flanges, also known as Screwed Flanges, for piping applications where a flanged connection is required without welding the flange directly to the pipe. These flanges feature internal threads that engage with the external pipe thread to create a mechanical connection.
Threaded flanges can be useful for selected piping systems where welding is not preferred or where installation and maintenance requirements call for a threaded connection. They are generally considered for suitable low-temperature and non-cyclic service conditions where the application is compatible with a threaded flange connection.
Our range includes stainless steel, carbon steel, alloy steel, duplex and super duplex steel, nickel alloys and copper-nickel materials. Products can be supplied in different sizes, pressure classes, face configurations, material grades and dimensions according to specified project requirements.
