din2565 din2566 threaded stainless steel flanges

DIN 2565 Threaded stainless Steel Flange is a special kind of flange in the DIN flange standard, commonly known as threaded flange, which is a BSPT or BSP inner wire floss on the inner diameter of the flange. The use of DIN2565 Threaded stainless steel flange is different from other Flanges. It is to process one end of the pipe into an outer wire floss and then rotate it with the flange, and connect the flange and the pipe with a thread. The characteristic is that the connection is fast and the construction is convenient. It is usually used in gas pipelines. In the pipe network system with a diameter of ≤DN150, DIN2565 Threaded Stainless Steel Flanges are often used.
    DIN 2565 ThreadedBS Stainless Steel Threaded Flanges are pipe fittings that connect pipes, Valves, pumps and other equipment to form a piping system. It provides convenience for the cleaning, inspection and maintenance of the pipeline.
   When in use, rotate the DIN 2565 Threaded stainless steel flange to the pipeline, connect the flange and pipeline to each other with screws, and then fasten the connection with Bolts to effectively connect pipelines, valves, pumps and other equipment accessories, so that the entire pipeline is constructed. As one, start working normally.
   The biggest features of DIN 2565 Threaded 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.
    It is the most widely used pipe fittings in the pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.
   Our DIN 2565 Threaded stainless steel flanges are made of standard material, finely machined, accurate in threaded Fasteners, 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.
Types of DIN 2565 Threaded Stainless Steel Flanges:
According to the model can be divided into: DIN 2565 DIN2566 DIN2567 BSEN TYPE 13, BS4504 TYPE 113,
According to the pressure can be divided into: PN16, PN10, PN25, PN40,
According to the process can be divided into: forging flange, casting flange
According to the material can be divided into: 304,304l,316,316l,321,201
 DIN 2565 DIN2566 /DIN Threaded stainless steel flange production process:
1) BS EN1092 Threaded stainless steel flange production process:
     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 annular flanges through forging machines such as forging presses and air hammers.
b: 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: 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 ring 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.
