Yes, FLEX-R® assemblies can have a primary seal weld and a secondary seal weld from the thermocouple to the flange assembly at the face of the flange, not on a single disk, and again after the secondary containment chamber.
What design verification is provided with the FLEX-R® flange assembly?
ASME code calculations are performed to determine the suitability and sizing of the primary connection, the secondary connection, and the secondary containment chamber. All welds are liquid dye penetrant tested (LPI). The assembly receives an inter ...
