Flanged thermowells are made from solid barstock stems welded to forged flanges and machined. 

Full penetration welds are available on all sizes, and available with CRN. Flange sealing face profiles are available as Raised Face, Flat Face, and Ring Type Joint. 

RF type sealing faces have a surface finish of 125 to 250 μin Ra (3.2 to 6.3 μm) for better sealing against gaskets. 

Tapered stems start off at a large root diameter and tapper down to the tip diameter. 

This design has a higher natural frequency making them more appropriate for systems with extreme dynamic conditions such as process lines with media flowing at high velocity.
