BS4504 PN16 Slip On Plate Plff PLRF FLANGES

BS4504 RF/PL/FF/SO Steel Flange is the most widely used 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. PN10 flange, PN16 low pressure Flanges are the most conventional and most useful.
    BS4504 RF/PL/FF flanges are a method of connecting pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
   Weld the BS4504 RF/PL/FF flange evenly with the pipeline, and then fasten the connection 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 the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments.
   Our BS4504 RF/PL/FF 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.
Types of BS4504 RF/PL/FF flanges:
According to the model can be divided into: BS4504 TYPE 101 PL, EN1092-1 TYPE 01, DI FLAT FORWELDING
According to the shape, it can be divided into: FF/PL flange, RF flange, Slip-On flange,
According to the pressure can be divided into PN16. PN10. PN25, PN40, PN63, PN100
According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange
According to the process, it can be divided into: forged flange, cast flange, steel plate flange
Flange production process:
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 ring flanges by forging machines such as forging presses and air hammers, 

b: steel plate flanges

   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
            Put the low carbon steel standard scrap into the intermediate frequency furnace and heat it to 1200-1500, pour it into the mold
            The type is a ring flange blank.
2) The formed 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.
3) For the finished flange product, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.

4) Type the flanges that have passed the inspection on the end face of the flange according to the customer's requirements, and do anti-rust treatment to the flange according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
