How long does it take to perform Thermal Integrity Profiling (TIP™) by the probe method?


Thermal Integrity Profiling is dependent on the shaft’s size (length & radius). If an engineer knows the shaft's size, they can estimate the test's duration. The thermal probe is lowered at a maximum rate of 0.5 feet per second. In order to confirm the data's repeatability, a minimum of 2 tests are required. For example, a 4ft (1.2 m) diameter shaft that is 100 feet (30 m) long, with 4 ccess tubes will take approximately 30 minutes to test. For information on not dewatering the tubes click here. Engineers should consider dewatering the tubes, however, despite the added time. The time to dewater a tube might be twice as long as testing the tube. Tubes longer than 50 ft – 15 m - may take even longer.
