Pipelines offer an economically and ecologically reliable, good solution for the transport
of liquids and gases worldwide. Even in a small country like Austria they are an
almost indispensable means of transport, especially for natural gas.
This work addresses the most important questions industrial engineers and scientists
are confronted with, when working in the fields of project planning, construction, and
operation of pipelines.
Starting from a description of the situation in Austria and a comparison with worldwide
solutions, the following fields are examined: Damage caused by cracks and corrosion,
as well as countermeasures; materials used in pipeline construction (ferriticpearlitic,
bainitic, and duplex-steels) and their processing properties (especially concerning
welding technology); aspects of materials testing and quality management.
Based on numerous welding-technological and fracture-mechanical examinations,
the influencing parameters and limits, essential for a problem-free construction and
reliable operation of pipelines, are discussed and limits established.
This part offers mathematical approaches for the predetermination of welding-technological
and fracture-mechanical parameters, to be considered during the construction
and the subsequent testing of pipelines.
