Surge Analysis

INERTANCE has performed the surge analysis for long pipeline as well as network system with various process upset conditions. This analysis study has used a computer based mathematical model of the system to calculate the surge pressure of transient events.

INERTANCE has a capability to perform below kinds of rotor dynamics analysis.

  • Steady State Analysis
  • Case Study for Transient Analysis
  • Surge Pressure ASME B31.1 and ASME B31.3
  • Water Hammer Analysis
  • Liquid Filled Piping System
  • Parallel Operation for Centrifugal Pump
  • Rapid Closure of a Valve
  • Emergency Shut Down by Power Failure, etc
  • Surge Control Measures
  • Air Chamber and Surge Tank

1. Surge Analysis (Water Hammer)

The surge phenomenon like water hammer describes a transient condition in piping systems caused when changing pressure or flow boundary condition, or changing operating condition of equipment such as pump and valve, etc. The surge pressure by transient condition is much higher than steady state, in which we should check if the piping design pressure is acceptable as per maximum allowable surge pressure.

2. Steady State Analysis

The pipeline is firstly modeled to analysis the steady state operating conditions for the purpose of the surge analysis. This initial study is useful to match the process condition with analysis boundary condition and input parameters.


3. Transient Analysis

The process events have to be defined as per operating condition with reviewing the relevant documents to perform the transient analysis. As per results of transient analysis, INERTANCE has checked whether the maximum allowable surge pressure is acceptable with design pressure and international standards.
