Blind Flanges
Blind Flanges
Blind flanges are typically used to blank off pipelines. They are bolted on to adjacent flanged pipeline assemblies, where their solid centre acts as a seal. The blind flange can also be adapted by machining into it a smaller bore or a threaded bore. This reduces the bore of the pipeline.
