Abstract: In order to solve the problem of flange joint leakage of reforming reactor,this paper analyzes the main reasons for the leakage based on the feedback from the jobsite.Aiming at the main reasons and combined with the situation of no domestic technical specifications for flange joint installation,the paper puts forward the corresponding precautions for flange joint assembly covering the installation of flange operated by professional technicians with special equipment;development of scientific and reasonable installation procedure,selection of special gasket,determination of adequate bolt pre-tightening force,machining of flange sealing surface,regular inspection and maintenance of flange,gasket and bolting after the use of the equipment and so forth.These precautions reduce the risk of flange joint leakage efficiently and guarantee the safe and stable operation of the reactor.
