THERMOWELLS
Protection wells are recommended for applications where the stem may be exposed to pressure, corrosive or high velocity fluids. The use of thermowell also permits instrument interchange or calibration check without disturbing or shutting down the process stream
BULB TYPE AND DIMENSIONS
The bulb is manufactured in AISI 316 seamless pipe and it’s made in two parts : sensitive portion (length depending on bulb diameter) and rigid extension (same diameter of sensitive part).
Bulb can also be in electro welded AISI 316 pipe.
MINIMUM LENGTH OF SENSING PORTION (see below table)
Valid for direct mounting or with capillary ≤ 10m and>10m
≤ 10m >10m
