Threaded flanges, or as commonly referred to as screwed flanges are manufactured with internal threads inside the bore of the flange. A threaded flange manufacturer uses highly ductile materials in its production like stainless steels to create internal threads. Since threads form a means of connection, they need to demonstrate a balance between toughness and ductility. Stainless steel is amongst some of the few materials that can exhibit this balance, which is why manufacturers often prefer using this to produce an Asme B 16.5 Threaded Flange. Even though the fastening of these flanges is by means of their internal threads, they can form permanent joints with high integrity.
The mating surface to this device is constructed with external threads that match the inner diameter of the bore and can connect to the internal threads of the npt threaded blind flange. The toughness properties of these flanges need to be high in order to prevent the deformation of threads. Unlike some flanges that may be used in low pressure applications, the Stainless Steel Threaded Flange proves to be an ally in high temperature and high pressure conditions. Usually, the media being ferried across via these flanges is air or gas or liquids like water. Solid and gaseous media often expel high pressure in piping systems, and hence need durable joints, as offered by BSP Reducing Flange. While most flanges need to be bolted or welded to form a connection, the threaded connection forged here ceases the requirement of a weld. The absence of welding eliminates the cause for intergranular corrosion, especially if high carbon stainless steel alloys are used in the manufacture of a Threaded Pipe Flange.
