    Pump Skid Grout Recommendation

    We are working on vibration problem for a 2500 hp skid mounted pump-motor assembly. The skid has 12" deep cavities between the top plate and bottom plate, for filling with material to stiffen the skid and increase the mass. The cavities have only had sand fill so that the skid could be...

    Guidelines required for Refinery piping vibration assessment

    I would suggest contacting the Southwest Research Institute, in San Antonio Texas.&nbsp;&nbsp;They have determined guidelines for displacement, velocity, and acceleration vibration values (all are equivalent measures of a given vibration) as functions of frequency.&nbsp;&nbsp;I don't know if...
