Pipe Stress Analysis

Pipe Stress Analysis is becoming more important as the demands on piping designers with respect to material saving, quality of design, plant safety, legislation, and not to forget liability, increase. What was often taken for granted in the past as being in accordance with good engineering practice must now be analysed using internationally recognized software tools.

Utilising such tools and experience in designing complex piping systems esn is able to offer an extensive range of Pipe Stress Analysis services that include:
  • Linear Static Stress Analysis and Non-Linear Stress Analysis
  • Dynamic Stress Analysis including:
    • Earthquake Analysis
    • Natural Frequency Analysis
    • Vibration Analysis
    • Surge and Water Hammer Analysis
    • Time History Analysis
  • Finite Element Analysis
  • Material Strength Analysis
  • Material selection, wall thickness and flange rating calculations
All Pipe Stress Analysis services are performed and conform to the requirements of European and International design codes, such as:
  • PED (Pressure Equipment Directive)
  • AD-Merkblatt
  • FDBR-Guidelines
  • AGFW
  • KTA
  • ASME B31.1
  • ASME B31.3
  • ASME B31.4
  • ASME B31.5
  • ASME B31.8
  • ISO 14692
  • UKOOA
  • BS 7159
Reports are generated and prepared in accordance with the client's requirements and our own in house engineering procedures, and are suitable for third party approval or for presentation to a relevant licensing or certifying body.

In addition, all relevant information needed by the piping designer such as, modifications to pipe routing or optimised supporting concept, allowable and calculated equipment nozzle loads, support loads, spring selection, expansion joint selection, etc are included and are clearly indicated in the reports and documentation supplied by esn.
