    Shear Pin Stress Concentration V-Notch vs. U shape grooved in bending

    I had already seen this reference but unfortunately it only provides regerence to V-notch in torsion, but not bending.

    Shear Pin Stress Concentration V-Notch vs. U shape grooved in bending

    Can someone link a website or attach a picture of a chart distinguishing the differences between the stress risers in a shear pin (round circular shaft) with a V-notch groove versus if it was a rounded groove. I have been looking but can only find charts, tables and graphs for round circular...

    Ball valve plugging with solids, alternatives ideas to fix problem?

    The solids are very dense when packed and wet. Nearly like wet thick cement. Not sure if we can use vibration to clear the solids as the valve is attached to the discharge of a pump and induced vibration could be a concern. The pressure is aroun 90 psig and is designed at 150 psig. If the valve...

    Ball valve plugging with solids, alternatives ideas to fix problem?

    I am having issues with solids building up in the 10” discharge ball valves on Mother Liquor Pumps that prevent operations from being able to close the valve. I have had a few discussions regarding ways to improve or eliminate this issue which have included insuring the valve is insulated/traced...
