What is the maximum recommended flange to flange length of a jacketed pipeline?

The maximum recommended flange to flange length of a jacketed pipeline is considered to be 6 meters. This recommendation is based on multiple factors, including the structural integrity of the pipeline, ease of installation, and maintenance.

Jacketed pipelines are often used to transport fluids that require temperature control, and having a manageable length for sections helps ensure that thermal performance is optimized. Longer segments can create difficulties not only in handling and installation but also in maintaining the uniform temperature distribution needed to effectively control the process fluid's temperature due to potential heat loss along the length of the pipe.

Choosing a length of 6 meters balances the practicalities of construction and maintenance with the operational requirements of the jacketed system. This standard length helps ensure that the flanges align properly and that the connections maintain their integrity under pressure. Adhering to this recommended length also simplifies the calculations involved in stress and pressure drop assessments for the pipeline system, which is critical for ensuring safety and reliability during operation.
