Separating one part of a line from another requires a spectacle blind, able to switch from closed to open and back again. Bleed rings provide a means to release pressure from the pipe through a controlled opening.

Spectacle flanges are known for their tensile strength, dimensional accuracy and durability. These flanges are made by using best quality material. We offers an extensive range of spectacle flanges in various dimensions and specification.

These types of flanges are made from plate, and come in 3 different types:

The first and most widely used type are spec blinds a short for spectacle: these are flanges with two equal outside diameter (OD) parts welded together by way of a a bridgea . One of the parts also contains an inside diameter (ID), while the other is a blank, or blind. A whole is put at the halfway mark of the bridge. These are also called spectacles, figure 8a s, and figure 8 blanks, because of their resemblance to reading glasses (spectacles) and figure 8a s. These are referred to as a Line Blanksa in the ASME/ANSI standards.
