The pipeline stability analysis is receiving increasing attention in natural gas pipeline engineering recently,however there are no relevant standards for HDPE pipeline stability calculation applied to natural gas in China.Through the contrastive analysis with GB 50332-2002 and AS 2566.1, the stability method of Australia natural gas pipeline engineering is applied according to the data of a certain natural gas gathering project in Australia.The result shows that the Chinese GB 50332-2002 Structural Design Code for Pipelines of Water Supply and Waste Water Engineering for HDPE pipe is basically agree with AS 25661 Buried Flexible Pipelines in Australia. But there are more analysis parameters to be considered in Australia.At the same time, the buried depth of pipeline based on domestic standard is more conservative.The Study can provide reference for projects.
