In 2017, Applied Bolting partnered with Bechtel, Carber, and the University of Houston’s College of Technology, for an independent evaluation of Applied Bolting’s DuraSquirt® Single Pass Flange System. The project scope also included a comparison to legacy, multi-pass, star pattern, tightening methodology. In 2018, The UH team released a brief summary of the year long study. A summary, of the study, can be downloaded below:
The following conclusions can be drawn based on the computational and experimental results obtained:
- ABT-DTI system is significantly faster than the ASME PCC-1 Legacy method by 60 to 70 percent.
- ABT-DTI system reliably produces a leak free connection upon startup.
- ABT-DTI system requires 75% fewer movements by the bolting operators.
- ABT-DTI system does not require the use of precision torques as compared to ASME PCC-1 Legacy technique.
- ABT-DTI system reliably yield these results with operators who have received minimal training and have limited experience with BFJA’s [bolted flange joint assembly].
