Our core business: Pipe Stress Analysis

In the course of plant planning, engineers are faced with increasing demands and challenges, especially concerning the effective management of materials, quality of design, plant safety, and compliance with technical codes and standards. In this context, pipe stress analysis is essential to fulfil these requirements and achieve optimal results.

As knowledge related to piping technology continues to develop the necessity, in this day and age, to analyse new and even existing designs using internationally recognised calculation methods is increasing. Also in this regard, esn provides professional support.

Customised analysis

With our experience in analysing complex piping systems as well as our know-how in the utilisation of specialised computer programmes, we are able to offer an extensive range of pipe stress analysis services, comprising:

  • Linear and non-linear static stress analysis
  • Dynamic stress analysis including:
    • Earthquake analysis
    • Natural frequency analysis
    • Vibration analysis
    • Surge analysis
    • Time History or Direct Integration analysis
  • Finite element analysis
  • Material strength analysis of pressure parts
  • Material selection, wall thickness and flange – flange joint calculations

All pipe stress analysis services are carried out in accordance with the requirements of recognised codes and standards, such as:

  • ASME B31.1
  • ASME B31.3
  • ASME B31.4
  • ASME B31.5
  • ASME B31.8
  • ASME VIII, Div. 2
  • EN 13480
  • EN 13445
  • EN 13941
  • ISO 14692
  • UKOOA
  • BS 7159
  • FDBR guidelines
  • AGFW
  • KTA
  • AD-Merkblätter

Comprehensive documentation and compilation of results

Documentation of the analysis results are prepared in accordance with the client’s requirements and due to their comprehensive and highly informative content are ideally suited for submittal to the relevant authority, notified body and third party inspection organisations.

In addition, all relevant information required by the piping engineer – such as modifications to pipe routing or optimised support concepts, allowable and calculated equipment nozzle loads, support loads, spring or constant element selection, expansion joint selection, etc. – are included in the reports.
