din2576 pn10 din2502 pn16 stainless steel flanges

DIN2576 DIN2502 stainless Steel Flange is a flat flange with pressure PN10 and PN16, which is the most widely used flange in pipelines. DIN2576 2502 is used in the market together with EN1092 Standard Flange and BS4504 PN16 flange standard. Din2576 DIN2502 stainless steel flange is the most common and most used pipe fittings in pipe connection. In particular, the DIN2576DIN2502 stainless steel casting flange has a low price and the quality meets the low pressure requirements. The biggest feature of DIN2576 DIN2502 stainless steel flange is good stability, strong corrosion resistance, acid and alkali resistance, and is an indispensable accessory for connecting pipes, Valves, pumps and other equipment to form a pipeline system. It is widely used in general industrial drainage, municipal pipeline sewage, civil pipeline drainage, low pressure gas pipeline and air conditioning pipeline.
   During construction and use, DIN2576, DIN2502 Stainless Steel Flanges are welded evenly at both ends of the pipeline, and then bolted to connect the pipelines, valves, pumps and other equipment accessories effectively, so that the entire pipeline is integrated and starts to work normally. .
   DIN2576 and DIN2502 are the most widely used pipe fittings in the piping systems and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, ships and other departments.
   Our Din2576 2502 stainless steel Flanges are made of standard materials, finely machined and priced in line with market demand. According to the needs of different markets and different customers, special molding and manufacturing can fully meet the requirements of customers and markets for different flanges. And inform customers of market needs so that customers can quickly expand the market.

DIN 2576 PN10 DIN2520 PN16 flange production process:
1) a: Forged flange
Cut stainless steel circular hacksaws of different specifications and models into cylindrical flange blanks, heat them to 1300 degrees in a reverberatory furnace, and take them out, and then forge the flange blanks into annular flanges by forging machines such as forging presses and air hammers, b : Steel plate flange
Put the 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 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 customer requirements, and the flanges will be individually packaged according to customer requirements, and then put into wooden boxes for shipment.
