Threaded flanges are threaded in the bore to match an external thread on the pipe. The threads are tapered to create a seal between the flange and pipe as the tapers approach the same diameter. These flanges are normally designed for low pressure, non-cyclic applications. more...
Threaded Flanges are used for special applications. They can be assembled without welding and can be used in extremely high pressure services--at or near atmospheric pressure--where alloy steel is essential for strength. Threaded flanges are not suited for conditions involving temore...
Threaded flange are referred to as either threaded or screwed. They are used to connect other threaded components in low pressure, non-critical applications. No welding is required. more...
