What is a Blind Flange?
The blind flange can be described as a flange without a hub or a bore in the center. They come with the same face thickness as that of a flange, along with a matching face type and a bolting pattern which is also quite similar. The blind flanges are used for sealing the ends of a pipe or the open nozzle of a pressure vessel. They are bolted to the pipes, which helps in providing easy access to the interior unlike a welded flange or cap.
The blind flange is a solid disk without any holes or openings, this prevents any liquid or gas from passing through it. The blind flange is placed between two flanges so as to stop the flow through the pipe. They help in performing repairs and maintenance inside the pipeline, by shutting off the pipe run easily. It also helps in speeding up the process of constructing a pipeline.
What is Carbon steel blind flange Face Types
Carbon steel blind flange, just like any other flange, comes with two types of faces, namely raised face and flat face.
What is the difference between blank and blind flange?
A blank flange can be described as a thin plate that is placed in between two flanges in the piping system, so as to stop the flow the pipe runs. Whereas, the blind flange is a thick solid plate with no hubs or bore in the middle but bolted holes throughout its perimeter. It helps to stop the flow at the end of the pipe.
Where is Stainless Steel Blind Flange used?
The Where is Stainless Steel Blind Flanges are used for sealing the ends of the pipes or the nozzle of the pressure vessel. They help to cut off the connection of a pipe, and also comes in handy when inspection or maintenance and repair works need to be carried out inside the piping system. The material grade of the flange is temperature and corrosion resistant, with high tensile strength and durability. Thus, they can be used for high temperature and pressure applications.
Blind Flanges for Hydro test
The hydro test for blind flanges is carried out so as to check its structural integrity. This is a type of pressure test, wherein the flanges are pressured to see if they are leaking. It helps to understand the strength of the flange.

A blind flange can be described as a solid disk used for blocking a section of a pipeline or nozzle. It has mounting holes around its perimeter and consists of gasket sealing rings machined into the mating surface. Unlike a regular flanges, blind flanges do not have an opening for the liquid to pass through them. These are placed between two open flanges to stop the liquid flow without any hassles. BLRF prove to be very useful during the maintenance work of a pipeline or add a new line or valve to the existing pipeline.
The blind flanges type 05 is widely used in installations, piping systems, or equipment construction to close an open end of the pipe. At Petromet, you will get BLRF of various qualities according to your requirements. We have a vast stock of fixings available for various pipe sizes and pressure classes (PN 6 to PN 100).
For some instances, BLRF flanges need a threaded hole to be tapped in the center for inspection or venting purposes. The flange must be thick enough to allow the effective thread length mentioned in the table below for tapped threaded holes. For other cases, a boss needs to be added for reinforcement. It is vital to ensure that the effective thread length T should be less than what is mentioned in the table in no case. The measurements are equal to the effective thread length of external pipe threads. Primarily, one can find the application of ½” tapping holes.

Where S is the connection size- NPS, and T is the minimum threaded length- mm.
To inspect the size and dimension of a blind flange, one needs to check the following things:
The dimensions are covered in ASME B16.5 for the size NPS ½” to NPS 24. It is covered in ASME B16.47 for the size above NPS 26" to NPS 60".
The primary purpose of a blind flange is to terminate the end of a pipeline. This makes the maintenance of the pipeline easier. It also helps in sealing the nozzle opening in a pressure vessel.
A blank flange can be described as a thin plate between pipe flanges in a pipeline to stop the flow. BLRF are thick, with or without bolt holes in the middle. It helps in controlling the flow through the pipe’s end.
