14. Buried piping modeling
Restrained zone #3
Sliding zone #2
Bending zone #1
Soil drop or swelling
Soil thaw

15. Soil Database contain soil properties, depth, soil type and insulation type is specified in pipe properties. That’s all you need to model buried piping with START

16. No need to select restrained and unrestrained zones for buried piping
No need to select restrained and unrestrained zones for buried piping. Everything calculated automatically
No need to run soil modeler each time you change your model. Soil springs are placed automatically during analysis. Very fast

17. START also consider the buoyancy of water and changing of the soil properties located in water (soil liquefaction)
Ground water level
Ground water level

19. Buried pipe insulation stress check
Stress is checked in 5 points
Equivalent insulation stress
Axial stress depend on steel pipe axial stress
Hoop stress, depend on steel pipe hoop stress from FEM model
Radial stress from FEM model
Shear hoop stress from FEM model
Shear axial stress, depend on axial friction force
Allowable insulation stress

20. High temperature piping with creep effect
High temperature piping creep effect
Creep lead to expansion stress relaxation (reduction) with time
Stress concentration zones
START ignore cold spring added by user for high temperature piping because code said so. Any cold spring will disappear due to creep relaxation

Time
Average stress - stress, at which the creep fracture is equal to real creep curve fracture
Stress after relaxation caused by self-spring after cooling down
- mean expansion temperature difference to consider stress relaxation,
- mean expansion temperature difference to consider self-spring in cold condition,
- real expansion temperature difference,
- creep diminish factor,
- creep self-springing factor.

22. START consider the remaining friction forces at the cold condition of the pipeline. No analog in other software. It is important for pre-stretched buried pipelines
Operation condition of above ground pipeline
Cold condition of above ground pipeline (after cool down). There’s a big anchor force due to remaining friction
Operation condition of buried pipeline
Cold condition of buried pipeline (after cool down). There’s a big anchor force due to remaining friction

23. Plastic piping analysis
