The hydrostatic test facility for the secondary side of steam generator

Description

The hydrostatic test facility for the secondary side of steam generator is used to implement the hydrostatic pressure test of the secondary side of steam generator after its on-site installation in NPPs. With this facility, the test medium (over 200t) can be heated to a specific test temperature, and the whole process of hydrostatic test including the pressurization and depressurization can be conducted.

Characteristics

The hydrostatic test facility, whose main devices are integrated into a container, can easily be transported.
Special designs are adopted so that the facility can be connected to the steam generator easily and fast.
With the test facility, the test medium in the secondary side of steam generator (over 200t) can be heated to a specific test temperature.
During the hydrostatic test procedure, the speed of pressurization and depressurization can be easily controlled with various methods. All the parameters in the test will be recorded automatically.

Heating power                   400kW

Achievements

lProviding of complete set of the hydrostatic test facility
The hydrostatic test facilities for the secondary side of steam generator manufactured by NPIC have been delivered to Hongyanhe and Ningde NPPs, and 3 SGs of Hongyanhe 1# unit have been tested by this facility. And now the manufacturing of the facility for Taishan NPP is underway.
lProviding of the training and technical supports
