Examples
Slugging Pulsating Pressure Source Characteristic & Measurement
Slugging in multiphase flows can be analyzed using piezocable pulsation measurement
Boiler Pressure Pulsation Measurement
Flow can drive Vortex Induced Vibration to cause Boiler Noise and Mechanical Fatigue
Small Bore – A Simple Structural Element that MAY Complicate Life
Small bore, a.k.a. appurtenance, pipes are often the first to fail from vibration fatigue. This simple element may cost large sums in lost production.
Angle and Order Analysis
When analysing machines, one may use time- or rotation- as the reference. This example explains how one can transit from a time- to an angle- basis.
Low Frequency Sound Transmission into Offshore Cabin
Offshore space is premium. Cabins tend to be compact, with complicated transmission paths
Strong Pulsation Causes Shock Waves inside Piping
Wave steepening becomes a problem when pulsation is high in comparison to the Line Pressure. The steepened wave results in shock waves.
Computed Order Tracking with Damaged Tach Pulse
Most signal analysis systems rely on the tachometer pulse being in pristine condition - this is not always the case
Waste Incineration and Mechanical Stress Measurement
One of the worst decisions you can make is to measure dynamic stress inside a waster furnace.
