Introduction to Threaded Flange

A threaded flange is a type of flange that has threads on the inside bore. This allows the flange to be screwed onto a pipe with external threads, creating a connection. Threaded flanges are commonly used in low - pressure applications and situations where pipes need to be easily assembled and disassembled. They offer a convenient way to connect pipes without the need for welding, which can be time - consuming and may require special skills and equipment. Threaded flanges are available in various materials such as carbon steel, stainless steel, and alloy steel, and come in different sizes and pressure ratings to meet diverse industrial requirements.
