Abstract: A comparison between СНиП Ⅲ-42-80* and GB 50369－2006 is given on the general requirements, groove line-up and welding, inspection and acceptance of welds, excavation, lowering in, crossing or overhead crossing, pigging and hydrotest. It is pointed out that a certain lag existed in СНиП Ⅲ-42-80* since it had continually been used from the 1987's amendment to now. Besides, GB 50369－2006 was more practical and consistent with China's current industrial level and pipeline construction status. Based on the analysis results, an amendment on GB 50369－2006 are proposed, including the relative technology requirements to be added on pipe laying, line-up, position of crosswise pipe joints in overhead crossing project and determination of hydrotest medium for mountainous pipe sections.
