On August 1, 2009, jingjiang yonghe polymer technology co., LTD., the winning red river in liaoning nuclear power plant first phase project rubber expansion joint, the rubber expansion joint diameter for (red river projects: DN2000, DN500, ningde plan: DN2700, DN500, yangjiang project: DN2800).

Liaoning province red river the first phase of nuclear power and the first phase of fujian ningde nuclear power plant installed capacity respectively 4 x 1000 mwe pressurized water reactor nuclear power generators, yangjiang nuclear power plant engineering capacity is 6 x 1000 mwe e pressurized water reactor nuclear power unit, adopting half speed (1500 r/min) steam turbine generator technology. Jingjiang yonghe relies on technology, business and so on various aspects advantage gained wide nuclear engineering co., LTD., the bidding management committee of the judges.

Previously, rubber expansion joint used in nuclear power projects in China depend on import, jingjiang yonghe polymer technology co., LTD., the bidding project for the first time the localization of nuclear power project rubber expansion joint.
