The fluid ends on high-pressure triplex mud pumps are exposed to high cyclic internal pressures. These fluid ends should therefore have adequate elastic strength and fatigue life under operating conditions. A method for increasing the fatigue life of the fluid ends is the auto-frettage process. The elastico-plastic behavior of fluid ends manufactured with side bores subjected to internal pressure has been studied both mathematically and experimentally. The mathematical analysis was carried out using an elasto-plastic finite-element approach. The experimental study, using direct strain-gage measurements, confirmed the mathematical analysis.
