Hazards and Safeguards of High Pressure Hydraulic Fatigue Testing

Abstract

The creation and transfer of hydraulic pressure at the 690-MPa (100, 000-psi) level is in itself hazardous. When this is used to fatigue cycle large pressure vessels to failure, the potential for catastrophic accidents is always present. This report summarizes the experience gained over several years of this operation wherein several hundred pressure vessels have been successfully taken to fatigue failure. Although accidents still take place, we have eliminated most of the personnel hazards, greatly reduced equipment damage, and are constantly striving to detect and eliminate any existing or new hazards. The hazards and safeguards are grouped into four areas of consideration: high pressure fluids, fragments, large components, and material handling.
