Description
150# Stainless Steel Blind Plate Flange
150# Stainless Steel Blind Plate Flanges are designed for low-pressure piping applications where a line must be sealed or flow must be stopped. Manufactured from stainless steel plate, these flanges provide a practical closure solution while offering corrosion resistance and straightforward access for future piping-system expansion.
Available in 304/L and 316/L stainless steel and covering sizes from 1" through 12", these blind plate flanges provide an economical alternative to heavier ANSI flange styles for compatible low-pressure service.

Blind Plate Design
A blind plate flange provides a solid closure at the end of a compatible piping system. Because there is no center opening for flow, the plate can be used to stop media movement and isolate the end of a line.
This removable bolted closure also makes future system expansion easier than a permanently welded end closure.
Serrated Sealing Surface
The flange surface is serrated to help improve sealing performance when used with a compatible gasket and mating flange arrangement.
Proper gasket selection, bolting, flange alignment, and installation practices should always be confirmed for the intended low-pressure application.
304/L vs. 316/L Stainless Steel
304/L Stainless Steel
- General-purpose corrosion resistance
- Suitable for many commercial and industrial applications
- Commonly used in water and process systems
- Low-carbon grade supports improved corrosion performance
316/L Stainless Steel
- Enhanced corrosion resistance in demanding environments
- Commonly selected for marine and chemical service
- Suitable for many chloride-exposed applications
- Low-carbon grade supports improved corrosion performance
Economical Low-Pressure Closure
Blind plate flanges provide a lighter, economical alternative to heavier ANSI blind flanges where the piping system operates within appropriate low-pressure conditions.
The plate construction makes them especially useful where a removable closure is required without the added mass or cost of a heavier forged flange.
Common Applications

Frequently Asked Questions
What is a blind plate flange?
A blind plate flange is a solid plate-style flange used to close the end of a piping system and prevent flow.
What pressure class is this flange?
This is a 150# blind plate flange intended for compatible low-pressure applications.
What sizes are available?
The listed size range is 1" through 12".
What material are these flanges made from?
They are manufactured from stainless steel plate conforming to ASTM A240/SA240.
What stainless steel grades are available?
These plate flanges are available in 304/L and 316/L stainless steel.
Why is the surface serrated?
The serrated surface is designed to help enhance gasket sealing performance in compatible flange assemblies.
Can this flange be used for future system expansion?
Yes. Because it provides a removable bolted closure, a blind plate flange can allow easier future piping-system expansion than a permanent welded closure.
How does a plate flange differ from a heavier ANSI blind flange?
The plate flange is intended as a more economical option for compatible low-pressure applications and is manufactured from stainless steel plate rather than a heavier forged flange configuration.
Where can I find the plate flange dimensions?
Use the Stainless Steel Plate Flange Dimensions PDF in the Product Documents section above.
Is there a product brochure available?
Yes. The Stainless Steel Plate Flange Brochure PDF is available in the Product Documents section above.
