In order to replace an XTRACTO-PAD® (model TC59-X) assembly do I need to buy all the accessories?
No. The tube clips, guide tube with weld-pad and the heat shield will be reused. Only the sensor element needs to be replaced. No welding is required.
What is a tubeskin thermocouple?
Tubeskin thermocouples are used for measuring the temperature of tubes in heaters or furnaces. The thermocouple measures the skin temperature of the tube itself.
Do I need expansion loops?
If you anchor a tubeskin thermocouple outside the furnace (fixed exit) and have any furnace tube movement you will need expansion loops. There are various expansion loops used such as S-loop, multiple coil, single coil and spiral loop.
