PIPING SYSTEM, VAPOR TURBINE PLANT, AND METHOD FOR CLEANING PIPING SYSTEM

摘要

A piping system (1000) for a vapor turbine plant comprises a piping member (100) having: a first pipe section (101) having a first flow passage; a second pipe section (102) having a second flow passage; a connection section (104) disposed between the first pipe section and the second pipe section and having a connection flow passage for connecting the first flow passage and the second flow passage; and a third pipe section (103) having a third flow passage connected to the connection flow passage through an opening, the piping member (100) being configured so that vapor is supplied to the first pipe section. The piping system (1000) for a vapor turbine plant further comprises: a vapor stop valve (60) connected to the third pipe section; and a turbine bypass valve connected to the second pipe section. The angle between a first center axis of the first pipe section and a second center axis of the second pipe section is greater than the angle between the first center axis and a third center axis of the third pipe section.
