ETA Designed, Built, and operates this DTR
- 580,000 lbf (2580 kN) maximum tension
- +/- 105,000 lbf (467 kN) cyclic tension
- 50,000 ft-lb (67.8 kN*m) maximum moment
- 42.5 ft (12.95m) (Flange to Flange) sample length
- Bolted design allows for future test modifications
- 100-horsepower (75 kW) HPU
- Data acquisition: Tension, Bend/Twist Angle, Bending Moment, Cycle Count, Length
DTR Reliability & Responsiveness
- Previous two 1-million cycle tests have averaged 7.5 months per test
- 3-hour drive from Houston
- Dozens of local machine and fabrication companies for repairs
- Dozens of local crane companies can have pipe sample out of rig in 2 days or less
ETA Recently Installed 200+ strain gauges on a flexible pipe
- 95% of gauges installed on the outer tensile armor survived 1,000,000 cycles of fatigue testing
- Custom NI software continuously logged 200+ strain gauges and 15 instruments to a single file
- Humidity & temperature controlled lab promotes proper strain gauge bonding
High Pressure Bore Cooling System
- Allows DTR to run at a high cycle rate without overheating pipe
- 10,000 PSI (700bar) @ 3-7 GPM (11- 27 LPM) flow rate
Average Million Cycle Test Duration of 7.5 Months
Bolted Design Allows for Design Modifications
