Bar stock thermowell with thread connection
Model: A600 series
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 with the process line operation, and the users are able to perform the maintenance procedure of the process line more easily. A600 series are seamless round bar type thermowell, and does not contain any welded area by processing the internal area of the round bar. It is designed to be installed onto the process line by using screw created on the thermowell, and normally used in the process line where the pressure and the current exist.
* Note. Depending on the material and U-length, the appearance of the connector may change.
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. 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 would be satisfactory from a corrosion standpoint.
■ Insertion
The distance from the end of the well to the underside of the thread or other connection means (Designated as "U") is the insertion length.
■ Bore size
Almost any installation uses several type of temperature measuring instruments. The selection of a standard bore diameter can produce extreme flexibility within the plant.
