Abstract:

 This research focuses on chemical pipeline design and material grade selection, aiming to enhance production efficiency, reduce accident risks, and ensure operational stability and safety. Firstly, the basic principles, processes, and key elements of chemical pipeline design were analyzed based on process requirements and environmental conditions, with discussions on achieving rational design. Secondly, material grade selection strategies were investigated by evaluating the impacts of physical and chemical properties of different materials on pipeline performance, along with practical recommendations for material selection adapted to specific working conditions. The findings provide scientific and practical references for industry professionals.

Key words: chemical pipeline, material grade, selection
