This reference page covers the key identification and installation-related details for a Blind Flange 10 Inch Class 600. Use the source data below when checking flange thickness, bolt arrangement, hole diameter, weight, and stud bolt information for drafting or procurement review.
For piping coordination, compare this flange with related flange dimensions, pipe schedules, gasket selections, and flange bolt patterns. These references help confirm that connected components are being reviewed as one assembly rather than as isolated parts.
Blind Flange 10″ Class 600
Blind Flange 10″ 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 10″ 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
A blind flange has no center opening. Unlike a flange intended to connect directly to a pipe bore, it closes a piping end, nozzle, or flanged connection. The solid face allows a line or piece of equipment to be isolated while preserving the possibility of later access, maintenance, inspection, or extension.
Understanding the Listed Dimensions
The dimension section identifies the nominal pipe size and its DN designation, then provides the flange thickness, weight, stud bolt description, bolt count, and hole diameter. These values should be read together when preparing a piping layout, fabrication detail, material takeoff, or connection check.
The stud bolt entry describes the threaded fastener size, thread form, alternate metric designation, and listed length. Bolt selection should still be coordinated with the flange facing, gasket arrangement, nut engagement, washer practice, and the actual joint stack-up. Do not infer a complete bolting requirement from the flange entry alone.
Design and Drafting Coordination
When placing this component in a CAD model or piping drawing, verify the mating flange, facing arrangement, gasket, and access needed for tightening and future removal. The downloadable DWG can support preliminary drafting and layout coordination, but project drawings should be checked against the governing specification and the approved component data.
For procurement or installation, confirm material requirements, gasket compatibility, bolt and nut details, corrosion or service requirements, and the applicable pressure-temperature basis. A flange class is not, by itself, a substitute for a complete engineering review of the joint and service conditions.

Frequently Asked Questions
What is a Blind Flange 10 Inch Class 600 used for?
It is used to close a piping end, equipment nozzle, valve connection, or other flanged opening where a removable blanking point is required. Typical uses include isolation, maintenance, inspection, and future connection work.
Does a blind flange have a center bore?
No. A blind flange is solid across its center and is intended to block the connected opening rather than pass fluid through the flange.
What does the Class 600 designation indicate?
Class 600 identifies the flange pressure-temperature class designation used for the component. The allowable service condition must be confirmed from the applicable material, temperature, design code, and project specification.
Why should the bolt details be checked with the gasket and mating flange?
The complete joint depends on the mating flange, facing, gasket, washers, nuts, and assembled joint thickness. The listed stud bolt information is an important reference, but it should be verified against the actual connection and installation requirements.
Can the DWG file be used directly for fabrication?
The DWG is intended to support drafting, detailing, and piping layout coordination. Before fabrication, verify the drawing against the approved project specification, required materials, mating components, and controlled engineering documents.
Is the listed weight the shipping weight?
The page provides a flange weight value, but the scope of that value should be confirmed before using it for shipping, lifting, support, or handling calculations. Bolts, nuts, gaskets, packaging, and other accessories may not be included.
