Abstract
Taking vibration problem of drain pipeline from a heater in heating network of one power plant as an example
the relation between vibration-exciting force of fluid flowing in the pipe and pipeline vibration response has been expounded through inspection in the field and combined with analysis of pipe vibration frequency and the oscillation mode. Directing against the operating condition and tubulature stress calculation
a technical scheme for remedy of the said vibration has been worked out
to install vibration damper for enhancing the rigidness of said pipeline.
