Blind Flanges Manufacturer in India

Forxar Industries Pvt. Ltd. is a trusted Blind Flanges Manufacturer in India, offering precision-engineered industrial blind flanges designed to securely close pipeline ends, valve connections, and pressure vessel openings. Our Blind Flanges, also known as BL Flanges or Blind Pipe Flanges, are widely used in industrial piping systems requiring reliable pressure containment, temporary isolation, maintenance access, and pipeline termination.

Blind Flanges are solid flange components without a central flow opening. Unlike Weld Neck, Slip-On, or Threaded Flanges, they are designed to completely block fluid flow through a flanged opening when properly installed with compatible gaskets and bolting.

Manufactured using carefully selected materials and precision machining processes, Forxar Blind Flanges provide dimensional accuracy, mechanical strength, and dependable sealing performance for demanding industrial environments.

Our industrial Blind Flanges are suitable for oil and gas, petrochemical, chemical processing, power generation, water treatment, marine, and general industrial piping applications.

How Do Blind Flanges Work?

Blind Flanges are designed as solid circular plates with bolt holes arranged to match the mating flange.

During installation, a suitable gasket is positioned between the Blind Flange and the mating flange. Stud bolts and nuts are then tightened using the appropriate assembly procedure to create a pressure-containing connection.

Because the Blind Flange has no central bore, it prevents flow through the closed connection when properly installed and maintained.

Blind Flanges are commonly used for pipeline termination, pressure testing, equipment access, and temporary or permanent closure of flanged openings.

For maintenance work, the system must be safely isolated, depressurized, drained, and verified before removing a Blind Flange. Additional positive isolation requirements may apply depending on the process fluid and plant safety procedures.

Frequently Asked Questions About Blind Flanges

What is a Blind Flange?

A Blind Flange is a solid flange without a central bore, designed to close the end of a pipeline, valve connection, or pressure vessel opening using a bolted and gasketed connection.

What are Blind Flanges used for?

Blind Flanges are used for pipeline termination, pressure testing, equipment maintenance, inspection access, and closure of unused flanged openings.

What is the difference between a Blind Flange and a Weld Neck Flange?

A Blind Flange has no central opening and is designed to block flow, while a Weld Neck Flange has a central bore and is butt-welded to a pipe to provide a continuous flow connection.

Can Blind Flanges withstand high pressure?

Yes. Properly selected Blind Flanges can be used in high-pressure applications when their material, pressure class, temperature rating, gasket, and bolting meet the required design specifications.

Which materials are commonly used for Blind Flanges?

Common material grades include ASTM A105 carbon steel, ASTM A182 stainless steel and alloy steel, ASTM A350 low-temperature carbon steel, and selected corrosion-resistant alloys.

Are Blind Flanges reusable?

Blind Flanges may be reused when their sealing surfaces, dimensions, materials, and structural condition remain suitable. Inspection and replacement of gaskets and bolting components may be required before reassembly.

Which standards apply to Blind Flanges?

ASME B16.5 provides requirements for applicable standard pipe flanges, while ASME B16.47 covers certain large-diameter steel flanges. Project-specific design and inspection requirements may also apply.
