Application of blind flange:
Blind flanges are commonly used in petrochemical, pipe engineering, public services and water works.A blind flange is useful for pipe maintenance.In fact,during construction of a pipeline,a blind flange may be installed at the end of the pipeline.This allows for expansion or continuation of the pipeline simply by adding onto the end flange.
