What is Threaded Weld Flanges?

Threaded weld flanges, sometimes called screwed weld flanges or screwed-on weld flanges, are a type of flange used in piping systems to connect pipes or valves. These flanges include a threaded connection that allows them to be screwed to the pipe or fitting, resulting in a secure and leak-proof junction. The welding technique creates a strong and durable connection between the flange and the pipe, ensuring stability and preventing leaks under pressure.

They can be used to connect pipes made of diverse materials, such as carbon steel, stainless steel, and alloy steel, as well as pipes of varying nominal diameter. Threaded weld flanges are available in a variety of diameters, pressure ratings, and materials to meet specific application needs.
