Threaded pipe flanges are the special type of flanges which can be attached to the pipe without welding. Threaded flanges are threaded in the bore which matches an external thread on the pipe. Threaded pipe flanges is just like to slip-on pipe flanges that are used with pipes that have external threads. It is used where small diameter and high pressure is required. These flanges are available in all materials, specifications, sizes and grades.

Key Features of Threaded Flange:

• No welding is needed
• Good for smaller pipe sizes
• Should be avoided for larger roads

Uses of threaded Flanges:

• It can be fitted to pipes of various sizes without welding
• Used in extremely high pressure applications
• Economical and time saving equipment
• Can be used in applications where welding is hazardous

Threaded pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is essential for threaded pipe flanges, the standard height is 1/16″ for threaded pipe flanges under 400#. For threaded pipe flanges of 400# and up, the standard threaded pipe flange raised face height is 1/4″.
