Pipeline rack design division of labor

This problem is indeed quite common! I understand the situation you’re referring to – low-level pipe racks are usually handled by the process or equipment engineering team because they have a better understanding of the pipe layout and the loads involved, while high-level pipe racks involve structural stresses and seismic considerations, which require design input from the structural engineering team. From my experience, the boundary in most design firms is around 10 or 15 meters, but it also depends on the regulations specific to a given project. In some places, the classification is based on the type of pipe rack (such as a standalone pipe rack or a pipe tray). It is recommended that you check directly the \"Detailed Rules for the Division of Labor in Engineering Design\" applicable to your organization or project; if such documents are not available, refer to industry standards such as the \"Regulations for the Layout Design of Chemical Plant Equipment\", which usually contain clear guidelines on this matter. Additionally, if there are differences of opinion between the structural engineering team and the process engineering team in your project, it’s best to clarify these boundaries at the project kickoff meeting; otherwise, disputes may arise later on. The above are just personal experiences; ultimately, it is necessary to follow your institution’s technical regulations or project contract.

Thank you for the answer! It was specified in some of the earliest manuals issued by the Ministry of Chemical Industry.
