Product: Hydraulic External Tensioner
PROVIDING
• Elimination of galled threads
• Uniform and repeatable loading
• Shorter turnarounds
• Reduced acceptance test periods
APPLICATIONS & FEATURES
• Standard tensioning solution for exposed threads above exiting hex nuts
• Modular design – common load cell with interchangeable puller screws available in any size thread and pitch
• Thread sizes ¾” to 4” for loads up to 615,000 lb
• Simultaneous tensioning as any number of tensioners can be linked together
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
