One of the functions of GOST Blind Flange is to block the end of the pipeline, and the other is to facilitate the sundries in the pipeline during maintenance. As far as the plugging effect is concerned, it has the same effect as the head and cap. But there is no way to disassemble the head, and the flange blind plate is fixed with bolts, which is very convenient to disassemble. GOST Blind Flange is made of carbon steel, alloy steel, stainless steel, plastic and so on.
GOST Blind Flange plays the role of isolation and cutting, which is the same as that of the head and pipe cap. Due to its good sealing performance, it is generally used as the best isolation method for systems that require isolation. A blind plate is a solid circle with a handle, used in systems that are normally isolated. The 8-shaped blind plate is shaped like an 8, with a blind plate at one end and a throttling ring at the other end, but the diameter is the same as that of the pipe, so it does not play a throttling role. GOST Blind Flange is easy to use. When isolation is required, the blind end is used. When normal operation is required, the throttle ring end is used. It can also be used to fill the installation gap of the blind flange on the pipeline. Another feature is that the logo is obvious, which makes it easy to identify the installation status.
GOST Blind Flange is not galvanized when used in oil medium systems, and should be hot-dip galvanized when used in other medium systems. The weight of the small galvanized layer of the stainless steel blind plate is 610g/m2, and the quality inspection of hot-dip galvanized is according to CB*/Z343.
