Product: Hydraulic Rod Tensioner & Hydraulic Rod Nut
PROVIDING
- Greater loads within restricted footprints
- Shortened turnaround times
- Easy adaptation for retrofitting to studs not extending above nut
Problem
Solution
1. Insufficient loading using conventional torqueing methods cased warped flanges
2. Leakage between stages due to gap between flanges (known as “smile”)
3. Labor-intensive operations led to over-budgeted turnarounds
4. Contaminants in the steam path
1. Simultaneous tensioning of studs provided precise loading allowing full flange closure
2. Developed sufficient clamping to overcome warping of inner casing
3. Labor hours drastically reduced – turnaround reduced by one month
4. Water-charged hydraulic nuts eliminated contamination concerns
