Stress analysis and Support design for Pipelines

Stress analysis is conducted to come up with innovative design solutions that meet international code compliances like IBC, UBC, BS, ASME, FEMA, API 618 and API 674. Design of structural steel supports for various piping systems are designed using FEM. These supports are designed using BS 5950 & ASCE.

Modeling & Analysis: The 3D modeling for the entire pipeline network with all the bends and runs along with initial support locations are captured and modeled using pipe stress analysis software Bentley-AutoPIPE.

The piping system are appropriately modeled accounting for their loss coefficient and elevation.

The analysis shows the displacement for the pipes at different locations and also the stresses caused due to operating & occasional loads. Various combinations of loading on the pipeline are provided as per applicable standards, which includes:
i) Dead load
ii) Pressure Load
iii) Thermal Load,
iv) Seismic loads.

Outputs: The output results are compared with allowable values of pipe material and if stresses or deflection exceeds allowable limits, suitable design modification are suggested to mitigate stresses. The results are presented in pictorially and tabular format in a report showing. :-

  • The stress ratio for the different load combinations.

  • Design modifications like additional supports & their types, if required in piping network, to reduce the stresses.

  • Marked AutoCAD drawings with support locations & additional supports and other design modifications, if required.

  • Forces & Moments acting on each support in all 3 directions.

  • Stress Isometrics for Piping network.

  • Structural steel support for Piping system to sustain various loads.

  • Minor details like base plate calculation, anchor bolt calculation & weld calculation are included in report for different types of supports.
