Problem

Solution

1. Non-uniform load distribution between casing halves with traditional torqueing methods and multi-jackbolt torque nuts

2. Resulting leak paths and sub-marginal acceptance tests

3. Extended delivery and commissioning times due to numerous adjustments required to achieve clamping uniformity

1. Uniform and repeatable clamping pressure

2. Trouble-free acceptance testing as leak paths are eliminated

3. On-time delivery and start-up
