Flanges are a type of pipe fittings that are used to connect 2 pipes or to terminated a pipe. One such type of flange is the Blind Flange that is used to end a pipe in the piping system. A Stainless Steel Blind Flange does not have a center or a bore. ANSI B16.5 BLRF Flanges is used to seal a nozzle opening of a pressure vessel. A Blank Flange provides easy access to the interior of the vessel since it is bolted. Unlike the flanges that have a cap welded onto them. 6 Inch Blind Flange is said to be a cost efficient way to seal the pipe. 4 Inch Blind Flange is easy to install and saves a lot of time and cost.
Valves might be located far from the job site hence Carbon Steel Blind Flange manufacturers In India recommend the use of these flanges to obstruct the flow of fluid close to the job site. Hence the placement of Blind Flange Class 150 in locations where the shutoff valve is used is sufficient. Using a Spider Blind Flange assists in disconnecting the flange downstream and preventing a leak or a spill. In most of the case, RF Blind Flange is used when there is a repair needed at a further point in the pipeline. It is common to use a Flat Face Blind Flange when one wants to shut down a pipeline or to install a new valve.
Alloy Steel Blind Flanges are available in the size range of ½ inch to 96 inches. Ring Joint Blind Flange has a raised face with a ring attached to it. It is typically used in high temperature or high pressure services at 800 degrees F. Ported Blind Flange has a hole that is surrounded by 4 or more tapped holes. Tapped Blind Flanges is a female port that requires a spot face for the o-ring to seal in it. Spectacle Blind Flanges can be coated with yellow zinc chromate, zinc plate, or can be galvanized if requested by the customer apart from standard black paint coating. This helps the High Hub Blind Flanges combat corrosion. Mechanical Joint Blind Flange is used in plumbing and engineering projects. These Blind Flange With Hole are used in different applications depending upon the requirement. Blind Flange With Threaded Hole manufactured by us is supplied to various companies in different industries.
