Nuclear forgings: PWR and BWR nuclear power is divided into two categories. Large forgings major nuclear power plant can be divided into the pressure vessel and reactor components into two categories. Pressure vessel containing: cylinder flange, nozzle segments, nozzles, upper cylinder and lower cylinder, cylinder transition section bolts. Reactor components are standard flange forgings under severe conditions of high temperature, high pressure, intense neutron irradiation, boric acid corrosion, erosion and hydraulic vibration, etc., so to choose 18-8 austenitic stainless steel to produce. Any product can not be a hundred percent perfect, Dingxiang flange is no exception. Although the overall assessment of the quality of Dingxiang flange forging relatively high standard, but inevitably some problems in the production and use of the process, some of our common flange failure to understand its general solution. If the flange leakage sealing, then explain it fails steel forgings standards, we can replace the forged seals to solve, if the flange is filled with sealant, then it would replace the sealant. This is the more traditional method of gear forgings standards, many manufacturers now technically been greatly improved, the use of a polymer composite material can be directly flange sealing leakage place. This material is relatively simple construction, the price is relatively low, is the ideal restorative material.
