B366 WPNCI Nickel Alloy Steel Flange Spectacle Blind ASME B16.48 600#
The Spectacle is a kind of pipe parts, mainly for easy maintenance, the specific shape you can
paint the upper part of the "8" black. That is, half of it is a blind plate and half of it is an iron ring.
Commonly used in pipeline flanges that need to change the process, the materials are mainly
carbon steel, stainless steel, alloy, and can be selected according to the pipeline pressure level
and pipeline medium.
Significance of use Usually used in pipelines with large pipe diameters, usually use one end of
the flange to occupy the spacing to keep the pipeline smooth, and replace it with a blind plate
of the same thickness at the other end to cut off the pipeline when needed. Avoid forced
expansion of pipelines due to temporary replacement of other blinds, affecting the entire system.
