Fitwel Industries LLP is a manufacturer and supplier of blind flanges in different grades and scales. We manufacture flanges of all types as well. Blind Flanges is used widely in applications where the pipeline has to be terminated. The blind end or the plate of the flange seals the connection so that the flow ends with the blind flange. As a leading blind flange manufacturer, & we supply these flanges in different types of material grade. Our experienced professionals are engaged with us who fabricate these flanges with excellent precision. This is a flange without a bore and is used to shut off a piping system or vessel opening. BLRF Flanges are manufactured without a bore and used to blank off the ends of piping, Valves, and pressure vessel openings.
The main purpose of using a Blind Flanges is to block off a section of pipe or a nozzle on a vessel that has not been used. A nozzle typically is a pipe that comes out of a vessel. Usually, a nozzle is flanged so it could be connected to either valves or piping. Several times, a nozzle will be blanked off with the help of Blind Flanges. This is practiced because of two reasons – i.e. for pressure tests in a plant, or simply since the customer may not want all the nozzles that were supplied on the tank. Typically, the best practice would be to use a standard gasket for these Tapped Blind Flange. Blind Flange ASME B16.5 Class 600, similar to standard pipe flanges, can be either raised face (RF) or flat-faced (FF). We offer these products at made-to-order sizes and shapes to our respected customers.
If the Paddle Blind Flanges is raised face, many Blind Flange Manufacturers in India, would recommend using a standard ring gasket that is appropriate for the service and/or test. Whereas if the Blind Flange Jis 10k is Flat-faced, manufacturers would usually recommend that the buyer use a full-face gasket. This is due to the fact that the most common reason the Blind Flange ASME B16.5 Class 150 is flat-faced. Hence, it is not designed to handle the bending forces that are a result of using a ring gasket or a raised face flange as compared to a flat-faced flange.
A Raised Face Blind Flange In Pn16 can be used to stop the flow in a pipeline. This is done with the help of a solid disk since there is no opening controlled in blind flanges, which allows the fluid to pass through. Instead, one placed the Blind Flanges between open flanges creates a block, which effectively causes the flow of a liquid to stop through the pipeline. These blind flanges typically have holes that are machined in order to match those of what might be a connecting valve or a flange that could be in that place. we are leading Blind Flange Suppliers In India.
These flat face BLRF Flange are used to blank off pipelines, valves, and pumps, it can also be used as an inspection cover. A blind flange is used to close ends of piping systems. These BLRF Flanges is available in various size, grades, Specification & thickness as per the client's requirements.
A blind flanges is a solid flange as shown below. The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. (A nozzle is typically a pipe coming out of a vessel and is usually flanged so it can be connected to valves or piping).
Many times a nozzle will be blanked off with a blind flange for pressure tests in a plant, or simply because the customer does not need all the nozzles that were supplied on the tank.
