BS4504 thread SO WN Blind carbon steel flange

BS4504 forged carbon Steel Flange is made of ST20, 20# high-quality low carbon steel billet after forging. BS4504 flange standard is the earliest flange standard and is widely used in the market. Now it coexists with BSEN1092-1 flange standard and is used together. . Among them, PN10 flange and PN16 flange are the most conventional, the most popular, and are widely used.
   BS4504 Forged Flanges are a method of joining 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 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 whole pipeline is integrated and starts to work normally.
   Its BS4504 flange is the most widely used pipe fittings in the pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.
   Our BS4504 flange material specification, fine processing, the price 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.
Types of BS4504 flanges:
According to the model, it can be divided into: TYPE 101 PL, TYPE111 Welding Neck, TYPE 113 Threaded,
TYPE 105 Blind,
According to the shape, it can be divided into: FF/PL flange, RF flange, Blind flange, Slip-On RF flange,
              Welding Neck flange,
According to the pressure can be divided into PN16. PN10. PN25, PN40, PN63, PN100
The production process of BS4504 forged flange:
1) Cut billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat them to 1000 degrees and take them out, and then forge the flange blanks into ring flanges through forging machines such as forging presses and air hammers.
2) The forged 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.
