din 2527 pn10 pn16 blind stainless steel flanges

DIN2527 stainless steel blind flange is the end of all pipelines. DIN2527 stainless steel blind Flanges are distributed at the very end of each pipeline system, indicating the end of the pipeline system. The biggest role is to facilitate the dredging and maintenance of pipelines. And the relative independence of each part of the pipeline. It is a special flange in ordinary industrial drainage, municipal pipeline sewage, and civil pipelines. When the blind flange is installed at the end of the pipeline, it indicates that the entire pipeline system is completed. The most commonly used DIN2527 stainless steel blind flanges are, din2527 pn10, DIN2527 PN16, DIN2527 PN25
 The biggest feature of DIN2527 stainless steel blind flange is good stability, strong corrosion resistance, acid and alkali resistance, and it is an indispensable accessory for connecting pipes, Valves, pumps and other equipment to form a pipeline system. It facilitates the cleaning, inspection and maintenance of pipes.
   There is no need to weld in use, just fasten the DIN2527 stainless steel blind flange flange with the flange at one end of the pipeline with Bolts to effectively connect pipelines, valves, pumps and other equipment accessories, so that the entire pipeline is integrated. Start working normally.
   It is an indispensable pipe fitting in the pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.
   Our DIN2527 stainless steel blind flanges are made of standard materials, finely processed and priced in line with market demand. According to the needs of different markets and different customers, special shaped manufacturing can fully meet the requirements of customers and markets for different flanges. And we will inform customers of market needs so that they can quickly expand the market.

According to the material can be divided into: 304,304l,316,316l,321,201

 DIN2527 stainless steel blind flange production process:
    
1) a: Forged flange
Cut stainless steel circular hacksaws of different specifications and models into cylindrical 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 through forging machines such as forging presses and air hammers.
b: Steel plate flange
2) 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 cake-shaped flange blank .
c: cast flange
In view of the characteristics of stainless steel, cast Stainless Steel Flanges are mostly made of precision casting. First, put the high-quality stainless steel quasi waste into the intermediate frequency furnace for heating, and add non-ferrous metals such as Ni to ensure the stability of the material. When the molten steel melts to 1500-1800 degrees, it is poured into the mold box to form a cake-shaped flange blank.
2) Put the formed pie flange blank into the annealing furnace for annealing treatment to ensure the stability and consistency of the ring blank material
3) The annealed pie-shaped 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.
