Temperature / catalogue / Design tool / Valid areas / EN – codes
Definition 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 limit
Limit stability
Use of LOGSTOR online tool on practical examples
Trench:Trench backfill material – compaction, what to inspect on site
Pipes in protection pipe
Lifting several pipes
Max trench length exposed with heat on
Shallow installation
Max. soil cover
Change in direction:Allowable axial stress level, Limit stability
Compensated system,
Preheated system ( in open trench)
E-comp system
High axial stress level ( without compensation)
Examples with online tool
