| Abstract:This paper discussed the key points of pipeline design for large-scale chemical pulp mills， based on the process technology sources， workflows， and engineering design experience of a certain large-scale chemical pulp mill. Based on an introduction to the fundamental requirements of pipeline design， it provided a detailed analysis of the pipeline design criteria for the oxygen delignification and washing/selection sections， as well as the bleaching section. Additionally， it addressed requirements for pipeline support design and stress calculations. The paper proposed a method that technical breakthroughs and industrial upgrading in pipeline design could be achieved through pathways such as strengthening technological research， emphasizing design planning， implementing standardized and modular design approaches， ensuring maintainability considerations， and leveraging domestic and international experience. |
