Bar stock thermowells
with flange connection
Model : A610, A611, A612, A623
Service intended
Temperature sensors or indicating type temperature gauges
are not directly inserted into the process pipe, unless these
are used to measure the outside temperature of process pipe,
instead, these are used with thermowells. By using
thermowells, sensors and gauges will not interfere the
process line operation, and the users are able to perform the
maintenance procedure of the process line more easily.
These types are most common bar type, and these are
installed onto the process line by attaching a flange. It is useful
in the process line where a high pressure and a fast current
exist. A623 is manufactured with a Full Penetration welding
procedure so can be used in a high pressure gas line.
Standard features
Selection of thermowell
MATERIAL
In general, the thermowell material chosen for the installation is governed mainly by the corrosion condition the themowell will face.
THERMOWELL
Recommended material for various services are given in the corrosion table.
Occasionally, the material consideration is one of strength rather than corrosion. For example, a stainless steel thermowell may be required for
a high pressure water service where otherwise a brass thermowell woule be satisfactory from a corrosion standpoint.

insertion length.
The selection of a standard bore diameter can produce
extreme flexibility within the plant.
TAPERED OR STRAIGHT TYPE
Tapered type thermowells provide greater stiffness for the same
sensitivity. The higher strength to weight ratio gives these
thermowells higher natural frequency than for equivalent length
