BS4504 PN16 RF/PL/FF stainless
Steel Flange is the most widely used flange in stainless steel flange, BS4504 flange standard is one of the earliest flange standards in the world, it is the most widely used in the market, and is widely used in engineering.
Among them, BS4504 RF/PL/FF PN10 flange and PN16 low-pressure stainless steel casting flange have low price and meet low-pressure requirements.
The biggest features of BS4504 PN16 RF/PL/FF
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. Pumps and other equipment are connected to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
When using, the BS4504 PN16 RF/PL/FF stainless steel 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. , starts working 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, food, and papermaking.
Our BS4504 PN16 RF/PL/FF stainless steel flange material specification, fine processing, 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.

BS4504 PN16 RF/PL/FF/SO 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 and take them out. Then, the flange blanks are forged into annular flanges by 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 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.
