This paper selects several representative penstocks codes of hydropower stations in China and foreign countries including USBR Standards (1970), ASCE Steel Penstocks (1993), Japanese Technical Standards for Gates and Penstocks (1993), the former USSR’s code My 34 747-76 and Π 780-83, and Chinese code DL/T 5141-2001; analyzes and compares their different design methods and corresponding safety levels. In addition, the probabilistic limit state design method adopted in DL/T 5141-2001 is described emphatically. What are described can be taken as reference by the engineering technicians who are engaged in the research, design and construction of steel penstocks for hydropower stations at home and abroad.
