Threaded flange looks very similar to Slip On flange but the main difference is that the threaded flange has been was bored out to match a specific pipe inside diameter. The backside of this center opening is then threaded with the relevant-sized tapered pipe thread.
Threaded Flange can be used in very high pressure services and their major advantage is that they can be assembled without welding.
A threaded flange is a connecting device that can be secured to a length of pipe without welding. Using a tapered thread, the threaded flange is tightened onto the pipe without leaking, however, a seal weld is commonly used, when appropriate. The nature of the threaded connection makes the threaded flange a viable option when welding is not feasible, such as highly flammable or explosive areas. This flange is commonly used only on smaller diameter pipes.
In many refineries, manufacturing facilities and shipyards, the highly explosive nature of the materials being moved via pipeline prohibit welding. In this type of environment, the threaded flange is often a good choice when assembling pipelines. Using a tapered thread inside of the flange, the pipe is tapered on its exterior and is threaded into the threaded flange. As the two tapers become enmeshed, the flange joint becomes tight and leak-proof. If conditions exist that deem welding safe, a seal weld is occasionally placed around the junction of the pipe and flange.
