AXIOM’s Mechanical function specialises in the design and engineering assessment of pressure systems. Our Mechanical Engineers have been providing support to owners and operators of high hazard plant for over 20 years, working closely with our clients to improve their assets’ life and reliability, whilst ensuring industry best practices are followed.

Our team is highly qualified and skilled in working with equipment which falls within legislative requirements including PSSR and COMAH. With a wealth of experience, our capabilities include working with pressure equipment design and fitness for service codes such as PD5500, ASME VIII, ASME B31.3, API 579 and BS 7910. Service offerings include:

  • Fitness for Service (FFS) Assessments
  • Design of Equipment Repair and Modification
  • New Equipment Design
  • Mechanical Data Sheet Development
  • Finite Element Analysis (FEA)
  • Pipe Stress Analysis
  • Third Party Review Services
  • Design Verification Certificates (DVC’s)
  • Fracture Mechanics

AXIOM’s Mechanical team sits alongside our Materials Engineering and Process Safety functions, to form AXIOM’s Engineering Services Division. The Engineering Services Division is supported by our UKAS accredited Inspection team, together forming a multi-disciplined service offering which allows AXIOM to deliver solutions of real value to our clients.

Take a look at our Mechanical service offerings for further details on how we can help you.

When reference to the original design code can not demonstrate FFS, AXIOM’s team of Mechanical Engineers are well versed with Level 1 and 2 FFS assessment methods to API 579.

Common deterioration modes:-

  • Locally Thinned Areas (LTA’S)
  • Pitting Corrosion
  • General Corrosion
  • Dents and Gouges
  • Laminations
  • Fire Damage

AXIOM can support our clients with the specification of equipment repairs when FFS cannot be demonstrated, and equipment modifications where required to support plant upgrades.

  • Autodesk Inventor 3D Modelling and 2D Drafting Software
  • Repairs Specified to Original Design Code
  • Repairs Specified to Post Construction Code (e.g ASME PCC-2)

Repair Methods Include:

  • Insert Plate
  • Patch Plate
  • Encirclement Sleeve
  • Like for Like Replacement

AXIOM has over 15 years experience of supporting clients with FEA studies. FEA offers a more in depth analysis, removing conservatism, and can be used to support the design of new equipment and investigate the FFS of aging assets.

  • Linear Elastic and Elastic-Plastic Analyses
  • Eigenvalue and Non-Linear Buckling
  • Thermo-Mechanical Studies
  • Design by Analysis
    • ASME VIII Div. 2 / BS EN 13445 / PD5500
  • Level 3 Fitness for Service
    • LTA’s
    • Pitting
    • Dents and Gouges
    • Thermal Distortion

AXIOM runs Bentley AutoPIPE software to assess piping systems to all major industry recognised piping design codes.
