Leak in the feedwater line of the hydrogen production boiler

2017-03-08View Original

Thread Content

Leaks are occurring at multiple flange connections on the feedwater line of my hydrogen production boiler. Would replacing the existing RJ-type flanges with FM-type flanges after shutting down the plant be effective? Dear sea friends, please provide guidance by discussing only the flanges with these two types of sealing surfaces.

For flanges weighing only 600 pounds, either flat flanges or octagonal flanges can be used; however, octagonal flanges are safer
