Blind Flanges Suppliers & Exporters in UAE

Blind flanges Suppliers in UAE is a solid disk used to block off a pipeline or to create a stop. Similar to a regular flange, Blind flanges in UAE have mounting holes around the perimeter and the gasket sealing rings are machined into the mating surface. The difference is that a blind flange has no opening for fluids to pass through. Instead, it is placed in between two open flanges, which stops the flow through a pipe. Many times this type of blockade is used when adding another line to an existing pipeline or when a new valve is being added. Blind flanges stockists in Dubai are commonly used in petrochemical, pipe engineering, public services, and waterworks.

Blind flanges in UAE are useful for making repairs to a pipeline further up the line. In fact, during the construction of a pipeline, a blind flange may be built into the final length of the pipe. This allows for expansion or continuation of the pipeline simply by adding onto the final flange. Without a blind flange, it would be next to impossible to repair or perform ongoing maintenance to a pipeline unless the flow was shut off at an earlier valve, which could affect miles of pipeline.
