Threaded Flange – A flange with internal threads that screws onto a threaded pipe without welding. Best for low-pressure, small-diameter, or flammable-area piping systems.
No welding required
Internal threading allows direct screwing onto pipe
Suitable for low-pressure & low-temperature services
Ideal for highly flammable areas where welding is unsafe
Quick and easy installation
Available in NPT, BSPT, BSPP thread types
Standards: ASME/ANSI B16.5, DIN, and others
A Threaded Flange (TH Flange), also known as a Screwed Flange, has internal threads that allow it to be screwed directly onto a pipe without welding. This makes threaded flanges ideal for low-pressure, non-critical applications, especially where welding is difficult or not allowed due to flammable surroundings.
They are widely used in small diameter pipelines and are preferred for quick installation and easy maintenance.
