COURSE PROGRAM
The aim of the training is to provide the necessary knowledge on design in accordance with the LOGSTOR design principles and the guidelines of EN 13941-1.
General presentation
Theoretical basis - Design Guide and EN 13941-1
Definiton of pipe systems
Temperature / pressure – lifetime
Project classes:
A-B and C – project classes / safety
Number of full load cycles
Fundamentals of bonded pipe systems in soil
Friction, expansion, natural fixpoint
Straight pipe sections
Allowable axial stress level, 150 / 190 MPa or no limitLimit stabilityUse of LOGSTOR online tool on practical examples
Trench
Trench backfill material – compaction, what to inspect on site
Pipes in protection pipe
