The spectacle blind is a kind of pipe parts, mainly for the convenience of maintenance. You can paint the upper half of "8" black to know the specific shape. It's half blind, half iron. It is commonly used for the pipeline flange that needs to change the process. The material mainly includes carbon steel, stainless steel and alloy. It can be selected according to the pipeline pressure grade and pipeline medium. The meaning of use is usually used on pipelines with large pipe diameter. Usually, one end of the flange is used to occupy the space to keep the pipeline unblocked. If necessary, the blind plate with the same thickness at the other end is used to cut off the pipeline. Avoid the forced expansion of pipeline caused by temporary replacement of other blind plates, which will affect the whole system.
