GOST12820-80 slip-on stainless
Steel Flange is one of the most widely used
Flanges in the world, GOST flange standard is widely used in Eastern Europe including Russia, Belarus, Ukraine, Kazakhstan, the former CIS countries and Mongolia, GOST12820 The slip on pn10 and pn16 type flanges are the most conventional, the most popular, and are commonly used.
GOST12820-80 slip-on stainless steel casting flange is low in price and its quality meets low pressure requirements.
The biggest feature of GOST12820-80 slip-on stainless steel flange is good stability, strong corrosion resistance, acid and alkali resistance, and is widely used in the pipeline system of chemical, pharmaceutical, food, pharmaceutical and other special industries. It is connected with other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
When using, the GOST12820-80 slip on stainless steel flange is evenly welded to one end of the pipeline with a special welding rod, and then fastened with
Bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the entire pipeline is integrated. normal work.
It is an indispensable pipe fitting that must be used in pipeline systems and equipment such as machinery, petroleum, chemical industry, water conservancy, medicine, food, and papermaking.
Our GOST12820-80 slip on stainless steel flange material specification, fine processing, and the price meets the 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 GOST12820-80 slip on
Stainless Steel Flanges:
According to the model can be divided into: GOST SLIPON
According to the shape, it can be divided into: FF/PL flange, RF flange,
According to the pressure can be divided into: PN10, PN16, PN25, PN40, PN63, PN100
According to the process, it can be divided into: forged flange, cast flange, steel plate flange
According to the material can be divided into: 304,304l,316,316l,321,201
GOST12820-80 slip on 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: 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 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 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.
