During the design, installation, and inspection of pipelines, various minor issues that have been overlooked or not taken into account are often identified. These issues are compiled into a series; the list is being updated continuously. Everyone is welcome to actively participate in discussions. This is a compilation post on common problems in Haichuan pipeline design – it’s still being updated, and discussions are welcome: https://bbs.hcbbs.com/thread-5705828-1-1.html ------------------------------------------------------------------ When designing and installing pipelines, it is essential to strictly adhere to relevant standards, ensuring that the locations of supports and hangers avoid all ring welds and meet the specified minimum spacing requirements. These are fundamental conditions for ensuring the long-term safe operation of pipeline systems.
