T/CSEE 0147-2020 Technical Regulations for Supervision of Installation Quality of High-Temperature and High-Pressure Pipeline Systems in Thermal Power Plants
T/CSEE 0147-2020
Basic Information
Scope
Main technical content: This standard specifies the scope of components, 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 reheated steam pipelines, low-temperature reheated steam pipelines, high-pressure feedwater pipelines, high-pressure bypass pipelines, low-pressure bypass pipelines, and feedwater recirculation pipelines in thermal power plants. The installation quality supervision of other pressurized steam and water piping systems with a temperature of 400℃ or higher or a pressure of 5.9MPa or higher can be implemented with reference to this standard.
