Tube-Skin Weld-Pad Thermocouples
Tube-skin and weld-pad thermocouples for furnace tubing, heater surfaces, and process equipment skin temperature monitoring.
Product Overview
Tube-Skin Weld-Pad Thermocouples
Tube-skin and weld-pad thermocouples for furnace tubing, heater surfaces, and process equipment skin temperature monitoring.
Tube-Skin Thermocouple Attachment Styles
Tube-skin assemblies are selected by attachment geometry, tube contact, lead protection, and heater environment so the sensor survives elevated-temperature surface service.
Tubing Attachment Style
Tube-contact format for fired heaters and process coils where direct skin measurement is required.
Protected Lead Exit Style
Weld-pad build with armored lead protection for higher-abuse routing and service-friendly field handling.
Tube-Skin Specification Drivers
Why Tube-Skin Temperature Matters
In fired heaters and reformer furnaces, tube metal temperature is the primary indicator of tube life. Exceeding the metallurgical limit of the tube alloy — even briefly — causes permanent creep damage. Tube-skin thermocouples provide the direct metal temperature measurement that fluid-immersion sensors cannot, enabling operators to manage heat flux and extend tube service life.
Dual-Element Option
Installation Note
Thermometrics can supply tube-skin weld-pad assemblies with the pad pre-tack-welded for customer final-weld, or with pre-welded installation completed in our facility on customer-supplied tube coupons. AWS D17.1 weld procedure qualification documentation is available on request.
