Overview

A spectacle flange is a specialty flange made of two metal discs attached in the middle by a small section of steel. Spectable flanges get their name because they look like a pair of reading glasses, or spectacles. Spectacle flanges, also known as spectacle blind flanges, are most commonly used on piping systems that need to be separated regularly or where the flow through the systems is regularly stopped. One end of the spectacle flange is solid, while the other end has a hole in the center. The spectacle flange can be rotated to place either the solid or hollow end within the pipe system, thereby opening or closing the flow.

The following are the five most important benefits of The following are the five most important benefits of flanges:

Easy assembly in tight spaces where wrenches may not have clearance if traditional flange fittings are used. With moderate torque, they’re easier to put together.
In hard-to-reach areas where flexibility is required, adapters in the hose line, pipe, or tube can be removed.
Pipe connections, tubes, or large hose links with high pressure, vibration, or shock pressures that could damage traditional large hydraulic fittings more easily.
In rigid lines such as metal tubes or continuous pipes, making connections allows for easy maintenance.
In demanding hydraulic applications, reduce the chance of components becoming loose.
