Cause Analysis of Leakage Occurred in Steam Piping Flange and Prevention Measures

FEI Ji-zeng (Dalian Branch,China National Petroleum Corporation,Dalian 116001,China)  
The failure mechanism of flange connection joint is complicated,Combined with the practice and the theory,the leak cause of steam piping flange was analyzed in full,and then,the application of elastic bolts was proposed.After the execution of this scheme for half year,there is no any leak occurred.It has been proved that the scheme is feasible.
