NEW EQUIPMENT AND TECHNOLOGY APPLIED IN WEST-TO-EAST GAS PIPELINE PROJECT

The great project of “West-to-East” gas pipeline helps abundant gas in West China transmitted to East China successfully. Therefore, a gas supplying network traversing from west to east, taking the Tarim Gas Field as its main gas source, areas at the Yangtze River Delta as its key target markets, connects each gas consumer along the pipeline with its trunk line, important branch lines and gas storage as its main body. By the end of 2006, a 5800 km long pipeline with total gas transmission of 15.8 CBM had been put into production and operation. As Chinese first long-distance gas pipeline with extremely large diameter and high pressure, the West-to-East gas pipeline has introduced many kinds of technologies and adopted various new equipments during its design, production and operation, as for which this paper reviews and sums up for the continual pipeline construction in the future to learn lessons and experiences from the previous great work.
