Screwed Flange

Screwed or threaded pipe flanges look similar to slip on pipe flanges but the bore of the flange is threaded, usually with BSP or NPT thread types.

Threaded flanges are used with pipes that have external threads.

The advantage of these flanges is that they can be attached without welding.

Threaded flanges are often used on smaller diameter pipes but are available up to 6” diameter.
