Read about START-PROF pipe stress analysis software
Straight buried pipe analysis is done for:
for buried gas networks – using SNIP 2.05.06-85;
for buried district heating networks with polyurethane insulation in polyethylene casing – using GOST R 55596-2013 and RD 10-400-01.
- friction factor, F - cross-section area, Q - backfill load
Input data can be copied using the
toolbar
icon and inserted into any other Start-Elements analysis by using the

External pipe diameter, D |
Pipe wall thickness, S |
Nominal wall thickness |
External casing diameter, Dc |
External insulation casing diameter. If insulation is absent, set as 0 |

Backfill soil number |
Trench soil number, can be selected from the soil database (see appendix 1 below) |
Operation pressure, P |
Operation pressure in operation state. Set for all standards except SNIP 2.05.06-85. More... |
Steel grade |
Pipe material from the materials database |
Depth, Z |
Minimum allowable depth (distance from soil surface to pipe axis). Soil prevents pipe swelling; therefore, increasing depth increases stability |
Axial force |
Maximum allowable compression force in the pipeline |
