Threaded flanges is a type of Flange that has internal threads on its bore, allowing it to be screwed onto a pipe or fitting with external threads. Threaded flanges are commonly used in low-pressure piping systems and are easy to install and remove without the need for welding. They are also useful in situations where the pipe or fitting being connected needs to be easily disconnected for maintenance or repair. Threaded flanges are available in a variety of materials, such as carbon steel, stainless steel, and brass, and can be used with different types of piping systems, including gas, water, and oil.

Difference between Threaded Flange and Square Flange:
Threaded flange is a type of flange that has threads on the inner bore of the flange. It is used to connect pipes with threaded ends. The threaded flange is screwed onto the pipe end and tightened with a wrench. This type of flange is commonly used in low-pressure applications.
Square flange, on the other hand, is a type of flange that has a square shape and is used to connect pipes with square ends. It is commonly used in high-pressure applications and is designed to withstand high pressure and temperature. Square flanges are typically welded onto the pipe end.
Threaded flanges are screwed onto the pipe end, while square flanges are welded onto the pipe end. Additionally, square flanges are typically used in high-pressure applications, while threaded flanges are used in low-pressure applications.
