Threaded Flanges is used for special circumstances with their main advantage being that they can be attached to the pipe without welding. Sometimes a seal weld is also used in conjunction with the threaded connection. This special type of flange is generally used for high pressure piping system, yet smaller diameter applications. Obviously, the larger the flange is, the harder the ability to machine a thread would be.
Threaded Flange Types There are two types of threaded flanges. One is to seal the two pipe ends with a certain sealing surface and a lens pad. This type of flange is mostly used for ammonia production. But it has been used less recently, and the lens pad has been replaced by a metal ring. The other type is the same as a normal flange, sealed with two flange sealing faces.
Facing Types There are two facing types for threaded flange, raised face flange and ring joint flange.
Raised Face Threaded Flange When the gasket surface area is above the bolted line of the flange, the raised face flange is easily identified. It is compatible with a wide range of gaskets, from flat to semi-metallic and metallic types, either ring or full.
RTJ Threaded Flange The ring joint flange has a circular groove to accommodate the ring joint gasket, which can be used when metal to metal seals are required. Especially in conditions for high pressure and high temperature.
Heavy oil refineries. Nuclear power (mostly seamless). Petrochemicals and acids.
