Effect of Fluid End Geometry and Autofrettage Process on Fluid End Field Life
Gorash, Yevgen (Co-investigator) Zhou, Xingguo (Co-investigator) Okorokov, Volodymyr (Researcher) MacKenzie, Donald (Principal Investigator)
Weir SPM (WSPM) manufactures a range of positive displacement pumps typically used for concrete pumping or fracking operations where the pump is subjected to high cyclic pressure and stresses and a severe environment that leads to corrosion and erosion. The pumps are manufactured in low alloy and stainless steel materials according to customer requirements.

Investigators at the University of Strathclyde (UoS) Department of Mechanical and Aerospace Engineering (MAE) previously generated IP related to the WSPM pumps (Mousetrap Project) which when transferred to Weir SPM resulted in major improvement to pump service life:
•Autofrettage pressure optimisation methodologies based on the ASME BPVC Div. 3, Section 8 fatigue assessment.
•Crossbore geometry optimisation and stress reduction using offset bores.
•Valve seat deck geometry optimisation that reduces the stresses in the inlet valve region.

The Research and Development projects proposed here address 3 areas of fluid end design and manufacture:
1.The significance of autofrettage of stainless steel fluid ends to corrosion-fatigue life.
2.Potential improvement of the autofrettage process for alloy steel fluid ends.
3.The significance of offset bore geometry to corrosion-fatigue life of fluid ends.

The contribution of autofrettage to corrosion fatigue life will be quantified through fatigue tests of pre-stressed, double notch material specimens of the form defined. The double notch specimens provide a relatively inexpensive means of simulating the autofrettage residual stress at cross bore regions of fluid ends by preloading the specimen prior to fatigue testing. 30 tests are proposed to cover a range of representative residual stress levels at appropriate working load levels. Fatigue testing will be outsourced to Doosan Babcock.
