We are manufacturer of Blind Flanges that are the used for blocking a pipeline or making a stop. This is a type of solid disk that is machined like a standard flange, the difference being that the mounting holes are present around the perimeter. Also, the mating surface is machined with gasket sealing rings. It has no sort of opening for permitting the fluid to pass through. This flange is used to cut off the liquid flow and for this it is inserted between two open flanges in the pipeline.

Blind Flanges are very important for the repairs and maintenance job works on the pipeline. Without these flanges, the shut-off of liquid flow will be possible only by shutting of the main valve that would be miles away from the actual repair location. Further, actual standard valves are costly and are known to be of sticking nature. On the contrary, blind flanges are more cost effective and easier way to seal off a pipe.

Installation of all types of blind flanges is simple. We manufacture different dimensions of this solid disk valve. These are included during construction of pipeline, into the final length of pipe. Doing this creates a unique design which helps in increase or continuation of pipeline by just adding it onto the end level. This is also possible during the addition of tees in the pipelines. A tee may be installed and thereafter blocked for allowing an extra option of operating a pipe at a later date.
