4.0 OPERATING PARAMETERS
4.1 Maximum Operating Conditions
The Isolator was designed for the operating conditions shown in Table 1.
Table 1: Maximum Operating Conditions
The Isolator can withstand temperatures of 350°F and beyond; however, extended periods of exposure to this extreme
condition should be avoided. Prolonged exposure to consistent elevated temperatures (>300°F) will accelerate the
degradation of the elastomer package, reducing the elastomer’s overall useful life. Elastomer kits rated for high
temperature use are available, please contact your Parker LORD representative for details.
The Isolator has no pressure rating limitations as it is pressure compensated with the downhole environment.
4.2 Maximum Static Loads
The maximum loads for the Isolator are shown in Table 2. Note that the recommended assembly torque is 250 ft-lb, well
below the maximum torque.
Table 2: Maximum Static Loads
Axial Load (Fishing Load)
4.3 Explosive Decompression
The Isolator was not designed to function following an explosive decompression event. If any such event should occur,
the Isolator should be removed from use, disassembled, assessed for damage, and any damaged components replaced.
