Product Description



GOST 12836 BLIND blind carbon Steel Flange is the last glimpse of all pipelines. It indicates the end of the pipeline system. The biggest function is to facilitate the dredging and maintenance of the pipeline, and the relative independence of each part of the pipeline. It is a common industrial drainage, Municipal pipeline sewage, a special flange in civil pipelines, when the blind flange is installed at the end of the pipeline, it indicates the completion of the entire pipeline system. GOST 12836 BLIND blind carbon steel flange, which is the most special of all flange standards, consists of three steps.
   GOST 12836 BLIND blind flange is an indispensable fitting for connecting pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes.

DIN2576 flange production process:
1) a: GOST 12836 BLIND forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat them to 1000 degrees and take them out, and then forge the flange blanks into cake-shaped flanges by forging machines such as forging presses and air hammers, b: GOST 12836 BLIND6 Steel plate flange
Put the steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a pie-shaped flange blank.
c: GOST 12836 BLIND cast flange
Put the low carbon steel standard scrap into the intermediate frequency furnace and heat it to 1200-1500, pour it into the mold
The type is a pie-shaped flange blank.
2) The formed pie flange blank is processed into a ring flange on a CNC machine tool according to the drawing, and then the flange is drilled with a CNC drilling machine according to the drawing requirements, and the finished product is completed.
3) For the finished flange product, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.

4) Type the flanges that have passed the inspection on the end face of the flange according to the customer's requirements, and do anti-rust treatment to the flange according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it.
