Polyurethane
(PUR) Insulation Stress Analysis according to EN 13941, EN
253, GOST 55596, CJJ/T 81. Stresses in insulation are printed
in insulation
stress report

Interaction
between the pipeline and surrounding soil are applicable for
horizontal, vertical and inclined pipes, pipes with variable laying
depth
  |
| Soil
properties are stored in the
soil
database
|
Ring
bending stress Calculation
|
For
submerged buried piping in liquefied soil with ballasting
weights

| Taking
into account soil subsidence, frost heaving, landslide,
seismic fault crossing
|
Take
into account stiffness of the PUR-insulation
layer and expansion cushions
