This reference provides the listed dimensions, weight, bolting information, and CAD resource for a 24-inch Class 600 blind flange. Use the technical values below when checking a piping arrangement, preparing fabrication documents, or coordinating a flange connection with related equipment.
A blind flange has no center bore, so it closes an open flanged connection rather than allowing the pipe to continue through the flange. The page also identifies the reference standard and provides a downloadable drawing for layout and detailing work.
Blind Flange 24″ Class 600
Blind Flange 24″ Class 600 is used to seal the end of a piping system or close off a flange connection in Class 600 service. It is a solid flange without a center bore and is commonly used in industrial piping systems, maintenance isolation points, and future pipeline expansion connections where a higher pressure rating is required.
This dimension data is based on ANSI / ASME B16.5-2020.

What Is a Blind Flange?
A blind flange is a blank flange used to close the end of a pipeline, vessel nozzle, or equipment connection. It provides a secure shutoff point and is often selected when future maintenance, inspection, or line extension may be required.
Common Applications
Blind Flange 24″ Class 600 is commonly used for:
- Pipe end closure
- Equipment isolation
- Valve and nozzle blanking
- Maintenance shutdown work
- Process and utility piping systems
- Higher pressure piping applications

Notes
Before fabrication or installation, always confirm the latest project requirements, flange material specification, gasket type, bolt length, and applicable pressure-temperature rating.
How to Use This Blind Flange Reference
Review the dimension list together with the mating flange, gasket, studs, nuts, and connected equipment. The flange thickness, bolt-hole information, bolt quantity, and stud dimensions all affect drafting and installation coordination. Do not treat the listed flange dimensions alone as a complete design approval; confirm the project specification, material requirements, gasket selection, and pressure-temperature conditions before procurement or fabrication.
Bolting and Connection Checks
The listed stud bolt size and bolt count should be checked against the mating flange and the project bolting specification. Hole diameter is also important during CAD detailing because it affects bolt clearance and the representation of the flange connection. Confirm that the selected hardware, tightening procedure, and access space are compatible with the installation.
CAD and Drafting Workflow
Use the downloadable DWG as a coordination reference for piping layouts, nozzle arrangements, maintenance planning, and flange detailing. Before issuing a drawing, verify the flange face arrangement, gasket interface, orientation, and connection requirements against the project documents. A CAD file should support the design process, not replace dimensional and specification checks.

Frequently Asked Questions
What is a blind flange used for?
A blind flange closes the end of a pipe, vessel nozzle, valve connection, or other flanged opening. It can provide an isolation point and may allow later access for maintenance or future system changes.
Does a blind flange have a center opening?
No. A blind flange is solid across its central area. Unlike a welding neck, slip-on, or threaded flange, it does not provide a bore for the pipe to pass through.
What information is provided for the 24-inch Class 600 flange?
The reference lists the nominal and DN size, flange thickness, weight, stud bolt information, bolt quantity, hole diameter, applicable standard, and a CAD drawing download.
What should be confirmed before ordering or installing it?
Confirm the flange material, mating connection, gasket type, bolting requirements, project pressure-temperature conditions, and the applicable design or purchasing specification. Also check the latest project documents before fabrication.
Can the DWG file be used as the final fabrication drawing?
The DWG is intended as a drafting and coordination resource. Review it against the listed technical data, project requirements, and approved engineering documents before using it for fabrication or construction.
