Stainless Steel Flanges are essential accessories for pipeline connections. According to the standards, they are divided into JIS BS DIN ANSI GOST Italian standards. Among them, DIN, JIS, and standard non-
Carbon Steel Flanges are the most common, the most popular, and are widely used. flange used. Stainless steel
Flanges are divided into two processes: forging and casting. Among them, cast stainless steel flanges are widely used in Europe and South Korea
The biggest features of 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. The purpose is to connect pipes,
Valves, pumps and other equipment to form Pipeline system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
When in use, the flange is evenly welded to one end of the pipeline with a special electrode, and then fastened with
Bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the entire pipeline is integrated and starts to work normally.
It is an indispensable pipe fitting that must be used in pipeline systems and equipment such as machinery, petroleum, chemical industry, water conservancy, medicine, and food.
Our stainless steel 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.
Type of flange:
According to the shape can be divided into: FF, RF, BLIND, SLIP-ON, Welding NecK
, Threaded, SocketWeld.
According to the pressure can be divided into: PN16. PN10. PN25, PN40, PN60, PN100,
According to the process, it can be divided into: forging flange, precision casting flange, steel plate flange
According to the material can be divided into: SUS304 SUS304L SUS316 SUS316L 321 201
Stainless
Steel 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 annular flanges through forging machines such as forging presses and air hammers.
b: stainless steel plate flange
1: Put the stainless steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a ring flange blank. 2: Design the template and cut it with a copy cutting machine.
c: Cast stainless steel 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 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.
