Xiaoshan, binjiang district, if there is a failure of natural gas pipelines, natural gas users in more than 200,000 households, will face large areas may occlude.
Recently, a 600 mm diameter, length of 2.6 km of high pressure natural gas pipelines in Hangzhou City, successfully crossing Qiantang River, Qiantang River for the first time by the end of this year is expected natural gas pipeline connecting between the two sides. The pipeline successfully Cross River, the biggest beneficiary is the Xiaoshan, Riverside and more than 200,000 users of natural gas.
After the pipeline connecting, to respond effectively to both sides of the Qiantang River supply and pipeline transportation of natural gas crisis that may arise, is equivalent to natural gas transport and insurance.
The 600 mm diameter high pressure natural gas pipeline, starting at qiantangjiang, fuchunjiang and Puyang Jiang River interchange, from the pond to North Bank of Qiantang River, finish 2.6 km across the River (the Qiantang River) tube full of crossing.
This is natural gas utilization project in Hangzhou City S11 program (Lion binjiang high and middle pressure valve Chamber at a pressure high pressure natural gas pipeline) which is part of. Remaining Lions valve Chamber to Qiantang north bank line, binjiang Middle pressure regulating station and South Bank of Qiantang River to the construction of a pipeline, will be launched in May.
By the end of this year, Hangzhou qiantangjiang River for the first time gas pipeline connecting between the two sides.
Hangzhou gas co officials said: "up to now, this is the only one across the Qiantang River in Hangzhou City pipeline. ”
Four-month-long, complete challenging high pressure natural gas pipeline crossing Qiantang River, what is the significance?
Hangzhou gas, Deputy General Manager Zhu Qinjun said, "watching this picture, you will understand. ”
From figure Shang can see, Hangzhou City gas group construction to "more points consistent, and ring supply" of gas supply pattern, entire pipeline on like ring with Hangzhou of a ring, all of adjustable pressure station, and gas source station and door station mutual through hand in hand, firmly ring live Hangzhou, North to p flat, West to Fuyang, and Yuhang, to East extends to Xia Sha, guarantee gas supply smooth constantly.
Zhu Qinjun explains, "ring-shaped pattern of aims, is interoperability between each regulator station, if one or several of them do not have a gas, or when a pipeline fails, ring-shaped pipe can still guarantee the smooth flow of natural gas, will not affect the supply of the entire ring. ”
If gas or upstream pipeline leading to the Riverside, Xiaoshan itself fails, most of the natural gas pipeline in the East has not yet been built, cannot in the short "reinforcements", Xiaoshan, Riverside will face "expired" dangerous, very serious losses.
2009 Hangzhou fear shortage of gas, it is because the upstream natural gas equipment failure, resulting in Hangzhou, North Gate Station of natural gas cannot be delivered to the user.
Zhu Qinjun says: "high pressure natural gas pipeline crossing Qiantang River, connected to the main city of Hangzhou, Xiaoshan, Riverside and, if this happens, then natural gas through a pipe network," reinforcement "of Xiaoshan and Riverside. Similarly, upper reaches of the main city of Hangzhou or the pipeline itself fails, Xiaoshan, Riverside also crosses the river the "reinforcements". ”
Gas group planning in construction of Xiaoshan, Hangzhou City South of LNG (liquefied natural gas) emergency gas stations, realization of Qiantang "dual insurance."
