gost blind 12836 stainless steel flanges

GOST 12836 BLIND stainless steel blind 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 stainless Steel Flange, which is the most special of all flange standards, consists of three steps.
   GOST 12836 BLIND Blind Stainless Steel Flange is an essential fitting for connecting pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes.
   When in use, the blind flange and the flange at one end of the pipeline are fastened with Bolts to effectively connect the pipeline, valves, pumps and other equipment accessories, so that the entire pipeline is integrated and starts to work normally.
   The biggest features of GOST 12836 BLIND Stainless Steel Flanges are good stability, strong corrosion resistance, acid and alkali resistance, and are widely used in pipeline systems in chemical, pharmaceutical, food, pharmaceutical and other special industries. Connected to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
  It is an indispensable pipe fitting in the application of pipeline systems and equipment in machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.

GOST 12836 BLIND stainless steel blind 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 1300 degrees to take 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
Steel flange: Make the corresponding mold according to the flange size, cut the stainless steel plate with a gas cutting machine according to the corresponding mold or put the stainless steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a ring 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) Put the formed ring flange blank into the annealing furnace for annealing treatment to ensure the stability and consistency of the ring blank material
3) The annealed ring 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.
4) For the finished flange, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.

5) The flanges that have passed the inspection will be laser-printed on the flange end face according to the customer's requirements, and the flanges will be individually packaged according to the customer's requirements, and then put into wooden boxes for transportation.
