PIPING STRESS ANALYSIS


CAESAR II Stress Analysis
PIPING STRESS ANALYSIS

The Pipex px® Engineering Services Team has a long and wide experience in providing static analysis in low pressure systems in 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.

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 also high loads on supporting structures. Aim towards an optimal design for both piping and structure.

Piping stress analysis project examples:

ADMA-OPCO Zakum fine filter skid – stress code compliance to ISO14692 for suspended BONDSTRAND® 7000M up to 14” diameter including support design, equipment nozzle checks and surge loads from hydraulic analysis.

BP Sullom Voe Terminal fire main – Stress code compliance to ISO14692 for new buried 24” BONDSTRAND® 2416C main with valve chambers and tie-ins to existing including surge loads from hydraulic analysis; road crossings to AWWA M45.

Sete Energy Saudia H2S Stripping Package – stress code compliance to B31.3 for various ASTM A-106 steel lines and UKOOA code compliance for BONDSTRAND® 2414 lines up to 10” including support design and equipment nozzle checks.

TOTAL Clov FPSO Headers– static analysis to ISO 14692 of 40” & 30” large diameter BONDSTRAND® 2425C headers for Mahle Industrial Filtration including support design and equipment nozzle checks.

Shell Prelude Floating LNG – Topside tank ducting stress code compliance to UKOOA for 18” BONDSTRAND® 2416C and ASME B31.3 for 18” 316L stainless steel including hanger support design, incorporating topside structural displacements, hull deflections and accelerations for operational and towing conditions.
