Determination of the damping ratio by multi-channel spectral analysis of seismic downhole data

Soil dynamic parameters such as the damping ratio are of major interest in earthquake engineering. We’ve currently published a publication which comes back to a relationship between attenuation and velocity dispersion of body waves which replaces the measurement of the amplitude characteristics of seismic signals by a frequency dependent velocity function. The implementation of this method ...

Flexible Coupling

Style W77 is the only flexible two-piece housing for 14'/350mm to 60'/1525mm piping systems. Style W77 provides limited linear angular movement to accommodate thermal pipe growth, vibration attenuation, seismic and other design considerations that require flexibility. Working pressures shown are based on standard wall carbon steel pipe roll or cut grooved in accordance with Victaulic ...
