T/CSEE 0147-2020 Technical regulations for installation quality supervision of high temperature and high pressure piping systems in thermal power plants (English Version)
This standard specifies the component scope, supervision content, witnessing methods and corresponding technical requirements for the installation quality supervision of high-temperature and high-pressure pipeline systems in thermal power plants. This standard applies to the installation quality supervision of main steam pipelines, high-temperature reheat steam pipelines, low-temperature reheat steam pipelines, high-pressure water supply pipelines, high-pressure bypass pipelines, low-pressure bypass pipelines, water supply recirculation pipelines and other systems in thermal power plants. The installation quality supervision of other pressure-bearing steam and water pipeline systems with temperatures greater than or equal to 400°C or pressures greater than or equal to 5.9MPa can be implemented with reference to this.
