Abstract: Significance to coordinate the relationship of the overlay segment in Zhejiang Province's planning natural gas networks and 2nd West-to-East Natural Gas Pipeline is reviewed. An analysis is carried out for the planning from distribution of gas resources, safety gas supply on an even keel, system of pipeline pressure levels, pipeline function and status. It is pointed out that Hangjinqu Segment in Hangquwan Pipeline shall be laid in the same direction with 2nd West-to-East Natural Gas Pipeline so as to make the gas networks of Zhejiang Province in "square-shaped loop gas pipeline networks" and the planning layout more reasonable. In this paper, authors describe a scenario of "multi-resources-loop networks" for the plan-ning and layout of gas networks in Zhejiang Province in detail.
