Van Stone Termowells
It is advisable to use full penetration welds for
flanged thermowells to achieve the highest fatigue strength rating. Forged
thermowells accomplish the same goal without welds, but at a much higher cost.
Van Stone style thermowells accomplish this without the
cost.
Van Stone termowells are machined from solid bar and are
connected using a separate and reusable backing flange. Van Stone termowells
mounted between mating flanges for pocess
insertion.
This design offers two
advantages:
1.
Any weld stress is
eliminated.
2.
The slip on flange not
being exposed to the process conditions can be of a less expensive
material.
Applications:
·
Chemical, process, apparatus and
plantengineering; petrochemical; on/offshore
·
High chemical
loads
·
High process
loads
