Each DTI is laser marked, detailing the flange diameter, class, and its position number, within the ring. There is a large number for installation crews to position all DTI's around the flange in numerical order, and smaller text along the OD for inspectors, to confirm proper placement.
Advantages
- 1. DTI system is significantly faster than the ASME PCC-1 Legacy method by 60 to 70 percent.
- 2. DTI system reliably produces a leak free connection upon startup.
- 3. DTI system requires 75% fewer movements by the bolting operators.
- 4. DTI system does not require the use of precision torques as compared to ASME PCC-1 Legacy technique.
- 5. DTI system reliably yield these results with operators who have received minimal training and have limited experience with bolted flange joint assemblies.
- Above data independently verified by the University of Houston.
