Application of 0.8 Design Factor in China Gas Pipeline

Abstract:

The paper reviews current situation of high design factor application abroad, and analyzes development of high-strength pipeline in China. It shows that related technology has greatly improved in China, such as manufacture of high strength pipe, inspection, quality control, pipeline construction and pipeline integrity management. So it is available to use 0.8 design factor for the class one location in China. And the paper also introduces trial section experiences in the third West-East pipeline on safety pre-assessment, design check, pipe specification, construction technology and integrity management plan. With relative specifications further perfected, it is promising to put the 0.8 design factor into a wide use in Chinese pipeline project.
