BS EN1092 stainless steel blind flange is the least used flange among all flange varieties, blind flange accounts for about 10% of pipeline
Flanges, or even less, BS EN1092 flange standard is the most used flange in the world One of the standards, widely used in engineering, the BS EN1092 stainless steel blind flanges are stainless steel plate cutting processing. Especially PN10 flanges, PN16 low pressure blind flanges are all
Stainless Steel Flanges.
The biggest feature of BS EN1092 stainless steel blind flange is good stability, strong corrosion resistance, acid and alkali resistance, and is used in branches of pipes,
Valves, pumps and other equipment or the top of each branch of the pipeline system. It provides convenience for pipeline modification, addition, cleaning, inspection and maintenance. Reduced engineering costs.
When using BS EN1092 blind flange, it is only necessary to fasten it with the welded flange at one end of the pipeline with
Bolts, without welding, to effectively connect pipelines, valves, pumps and other equipment accessories, so that the entire pipeline is structured. As one, start working normally.
BS4504 stainless steel blind flange is widely used in the pipeline system of chemical, pharmaceutical, food, pharmaceutical and other special industries. It is less but essential in the pipeline system and equipment of machinery, chemical industry, water conservancy, electric power, shipbuilding, etc. pipe fittings.
Our BS EN1092 stainless steel blind flanges are standard in material, 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.
BS EN1092 Stainless Steel Blind Flange Type:
According to the model can be divided into BS BLIND BS4504 TYPE 105 Blind, EN 1092 TYP05 DIN2576
According to the pressure can be divided into PN16. PN10. 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
According to the production process, BS4504 blind flanges can be divided into: forged flanges, cast flanges, steel plate flanges
1) a: Forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat them to 1000 degrees to take out, and then forge the flange blanks into cake-shaped flange blanks through forging machines such as forging presses and air hammers.
b: stainless steel plate flange
Make the corresponding mold according to the flange size, cut the stainless steel plate according to the corresponding mold with a gas cutting machine 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
According to the characteristics of stainless steel, casting stainless steel flanges mostly adopts the precision casting method. 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, pour it into the mold 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 according to the drawing on the CNC machine tool, 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.
