Heat Transfer in Gas Transmission Pipelines
Understand the process of heat transfer in gas transmission pipelines and its impact on fluid temperature profiles. It explains how the fluid temperature in pipelines typically decreases towards ambient conditions due to heat transfer to the surroundings. The snippet discusses the key factors influencing heat transfer, including the temperature gradient and the overall heat transfer coefficient, which is derived from conduction, convection, and, less commonly, radiation. Understanding these principles is crucial for addressing flow assurance issues such as condensate dropout, freezing, and hydrate formation, particularly in cold environments or subsea applications. This content is essential for pipeline engineers and students focusing on thermal analysis and flow assurance in pipeline systems.
