Pipeline Engineering 2

ABSTRACT

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.

THEORETICAL PART:

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.

EXPERIMENTAL PART:

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.

MATHEMATICAL PART:

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.
