CAESAR II piping stress analysis

The Fiber Glass Systems Engineering Services Team in Plymouth has a long and broad experience in providing static and dynamic analysis in pressure systems for thermoplastic, thermosetting (GRE) and metallic piping for suspended, buried, marine, industrial and offshore applications.

In combination with CAESAR II, the most widely used pipe flexibility and stress analysis software, we carry out detailed piping stress analysis, evaluating and confirming structural and operational integrity of process piping systems to ensure compliance in accordance with international piping codes and standards ISO14692, B31.3, UKOOA, BS7159, API610 and AWWA.

Technical specification:

  • International piping code database
  • Automatic stress isometric creation
  • Material physical and mechanical property database
  • Hanger design and database
  • Expansion joint database

Key features/benefits:

Structural Integrity

  • Design adequacy for the pressure of the carrying fluid
  • Failure against various loading in the life cycle, limiting stresses below code allowable

Dynamic & Seismic Analysis:

  • Utilising CAESAR II dynamic module, we can carry out checks for earthquake effect and natural frequency of the system to ensure integrity through the design life

Operational Integrity

  • Limiting nozzle loads of the connected equipment within allowable values
  • Avoiding leakage at joints
  • Limiting sagging & displacement within allowable values

Optimal Design:

  • Avoiding excessive flexibility and high loads on supporting structures
  • Optimal designs for both piping and structures

Support Verification:

  • Selection of optimal spring hangers if required
  • Evaluate support lift off, friction and gap closure
