ASME B16.48 has two washers, one blind and one annular. They can be mounted in a system in open or closed position. Goggle blind flange manufacturers in India produce different types, such as stainless steel goggle blind flanges or different classes, such as the spec blind. The asme b16.48 spectacle blind flange has the gasket and screw holes in the flat side, so the screws often go through the gasket as well.
The ASME B16.48 is used in maintenance facilities where opening and closing of piping systems is required. The carbon steel spectacle blind flange belongs to the ASME B16.48 class of pipe insulation devices. Depending on the need for an elevated surface, the spectacle blind flanges can be used. On the other hand, if a tight seal is required, the gland blind Figure 8 can be used. These can be rotated to change the position from closed to open and vice versa.

Frequently Asked Questions
Most frequent questions and answers
What is a spectacle blind flange?
A spectacle blind flange is a type of pipe flange that is used to isolate or blank off a section of pipe. It consists of two pieces: a solid disc that is used to blank off the pipe, and a loose ring that is used to isolate the pipe.
What is the difference between a spectacle blind flange and a regular blind flange?
A regular blind flange is a solid piece of metal that is used to blank off a pipe, while a spectacle blind flange is made up of two pieces: a solid disc and a loose ring. This allows the flange to be used for both isolation and blanking off of a pipe.
How is a spectacle blind flange installed?
A spectacle blind flange is installed by first bolting the flange to the pipe, and then inserting the solid disc into the flange. The loose ring is then placed around the disc, and the bolts are tightened to secure the flange in place.
What materials are spectacle blind flanges typically made of?
Spectacle blind flanges are typically made of carbon steel, stainless steel, or alloy steel, but can also be found in other materials such as aluminum and plastic depending on the application.
What function does a spectacle blind flange serve?
A spectacle blind flange serves two main functions: isolation and blanking off. The solid disc part of the flange is used to blank off a section of pipe, effectively blocking the flow of fluid or gas through that section. The loose ring part of the flange is used to isolate the pipe, separating it from the surrounding environment while still allowing for inspection and maintenance. This combination of functions allows a spectacle blind flange to be used in a variety of industrial settings, such as oil and gas, power generation, and chemical processing.
When is a spectacle blind necessary?
A spectacle blind is a type of pipe fitting that is used to isolate or block off a section of a pipe or vessel. It is typically used in situations where maintenance or repairs need to be performed on a specific section of a pipe or vessel, or where a section of the pipe or vessel needs to be taken out of service temporarily. Spectacle blinds are also used in situations where a pipe or vessel needs to be temporarily isolated for safety reasons, such as during a process shutdown or emergency. They are also used in situations where a pipe or vessel needs to be isolated for cleaning or inspection.
What are the standard sizes for spectacle blind flanges?
The standard sizes for spectacle blind flanges vary depending on the industry and application, but they typically range from 1/2″ to 36″ in diameter.
