GOST Standard Forging Blind Flange

GOST Standard Forging Blind Flange The blind flange is a form of flange connection, that is a flange without a hole in the middle. There are many kinds of sealing surface, such as plane, convex surface, concave convex surface, tenon and groove surface and ring joint surface. One of the functions of the blind flange is to seal the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. In terms of plugging effect, the blind flange has the same effect as the head and cap.  Parameters: Type: Blind flange Pressure: 1) ANSI B16.5: CLASS150. 300. 600. 900.1500. 2500 2) JIS 2220: 1K. 2K. 5K.10K.16K. 20K. 30K 3) DIN/GOST/EN1092/BS4504: PN6.
