"Replaceable Furnace Tube Skin Thermocouple Assembly"

Accurate reliable temperature measurement for process furnaces is a priority throughout the refining and petrochemical industry.  Traditionally tube skin temperature measurement systems have required the welding and or peening in of the thermocouple on the tube.  This activity had to be repeated if the thermocouple failed.  GAYESCO'S new patented 'XTRACTO-PAD" thermocouple system allows for replacement of the thermocouple without rewelding.  This results in significant cost savings to the operator and provides a practical solution to tube skin temperature measurement.

Data Sheet

The basic configuration for the 'XTRACTO-PAD" design is similar to the "REFRACTO-PAD"; this design has proven to be a popular means of furnace tube skin temperature measurement throughout industry.  The novelty of the "XTRACTO-PAD" involves improvement in the area of replace ability, while maintaining the accuracy and dependability of the device.

The differences are:

1.     The weld pad is fabricated as part of the guide assembly.

2.     The heat shield is modified to keep the weld pad/guide assembly in position.

3.     The tube clips that hold the thermocouple in place are reusable
