Blind Flanges

A blind flange is a popular type of pipe flanges. It has no bore in the center,and is primarily used to close the ends of piping systems.This flange premits easy access to a line once it has been sealed.It sometimes can be machined to accept a nominal sizes pipe to which a threaded or welded reduction is being made.Haihao steel blind flanges are available in various sizes and material for you to choose from.

Without the blind flange it would be difficult to perform maintenance or repairs on a pipeline. The flow would need to be shut off at the nearest valve, which could be miles away from the repair area. Valves are also very expensive and are prone to sticking. The blind flange is a much more cost efficient way of sealing a pipe.

Blind Flanges are commonly used in petrochemical, pipe engineering, public services and water treatment etc.
