With the development of materials and processes,non-metallic and composite materials pipes are gradually replacing metal pipes in the field of pressure pipelines and are widely used due to their many excellent characteristics.This paper analyzes the main types and characteristics of non-metallic pressure pipelines.Based on the investigation of the current application status and development research trends of non-metallic pressure pipelines in China,this paper focuses on the practical situation and prospects of non-metallic pressure pipelines in key fields such as city gas,oil and gas field surface facilities,and petrochemical equipment.Relevant safety protection suggestions are proposed for the existing problems in the application.
